JP6164032B2 - Program, input screen display method, and information processing apparatus - Google Patents

Description

  The present application relates to a program, an input screen display method, and an information processing apparatus.

  Before the input information entered by the user on the input screen of the browser is transmitted from the terminal device to the web server, the session expiration date may elapse. Even if input information is transmitted from the terminal device to the web server after the expiration date of the session has elapsed, the web server does not accept the input information. When the user accesses the web server again, the input screen is displayed in the browser in the initial state, and the user has to input the input information from the beginning.

  Therefore, there is a technique for temporarily storing input information input by the user before the expiration of the session in a web server (for example, Patent Document 1). As a result, the input information transmitted from the terminal device to the web server does not disappear even after the expiration date of the session has elapsed. When the web server receives the input screen request from the terminal device again, the web server restores the input screen using the saved input information, and transmits the restored input screen information to the terminal device.

Embodiment 1
FIG. 1 is a block diagram illustrating a hardware configuration example of the online system 10. The online system 10 includes a terminal device 20 and a web server 30.
The terminal device 20 is a desktop PC (personal computer), a notebook PC, a tablet PC, a smartphone, or the like. The web server 30 is a PC, a workstation, a general-purpose computer, or the like. In the following, it is assumed that the terminal device 20 is a desktop PC and the web server 3 is a workstation.

The terminal device 20 and the web server 30 are connected via a network 1N. The network 1N is, for example, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), a telephone communication line, a satellite communication line, or the like.
In FIG. 1, three terminal devices 20 and one web server 30 are depicted, but the number of terminal devices 20 may be two or less, or four or more, and there may be a plurality of web servers 30. There may be.

  FIG. 2 is a block diagram illustrating a hardware configuration example of the terminal device 20. The terminal device 20 includes a CPU (Central Processing Unit) (display control unit, storage control unit, determination unit, update storage control unit) 21, ROM (Read Only Memory) 22, and RAM (Random Access Memory) 23. The terminal device 20 includes a hard disk (storage unit) 24, a disk drive 25, a display unit 26, an operation unit 27, a timer (timer unit) 28, and a communication unit (reception unit, transmission unit) 29.

  The CPU 21 is a processor for executing an instruction set described in the software program. The CPU 21 controls each component of the terminal device 20. The CPU 21 reads the program 2P stored in the hard disk 24 to the RAM 23 and executes the program 2P read to the RAM 23.

  The ROM 22 is a read-only storage medium, for example, a nonvolatile semiconductor memory. The ROM 22 stores a BIOS (Basic Input / Output System) executed by the CPU 21 when the terminal device 20 is activated, firmware, and the like.

  The RAM 23 is a main storage device. The RAM 23 is, for example, SRAM or DRAM, and temporarily stores work variables, data, and the like that are necessary in the course of processing executed by the CPU 21. Note that a flash memory, a memory card, or the like may be used instead of the RAM 23.

  The hard disk 24 is an auxiliary storage device. The hard disk 24 may be replaced with a flash memory capable of storing a large amount of information or an optical disk 2d such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a BD (Blu-ray (registered trademark) Disc). . The hard disk 24 may be attached inside the terminal device 20 or may be placed outside the terminal device 20.

The hard disk 24 stores a program 2P executed by the CPU 21, a cookie file 2c, and an input information saving file 2f.
The program 2P includes a browser program and browser add-on software. The cookie file 2c is a text file that stores the session ID received by the terminal device 20 from the web server 30 and the session expiration date (cookie expiration date). The input information save file 2f is a document file that temporarily stores input information input by the user from the input screen of the browser, and is not limited to a specific format. The input information save file 2f is, for example, a file in text format, csv format, tsv format, prn format, HTML format, XML format, table format, or the like.
The cookie file 2c and the input information saving file 2f have different storage destinations (paths) in the hard disk 24.

The cookie file 2c may be discarded when the browser is closed. On the other hand, since the input information saving file 2f is independent of the cookie, even if the browser is closed or the terminal device 20 is shut down, it is stored in the hard disk 24 unless deleted by the processing of the program 2P. Remain.
If the terminal device 20 is infected with spyware, the storage location of the cookie file 2c is known for each type of browser, and thus the content of the cookie file 2c may be stolen. However, since the storage location of the input information saving file 2f is different from the storage location of the cookie file 2c, the risk that the input information written in the input information saving file 2f is stolen is low. Accordingly, the fact that the storage destinations of the cookie file 2c and the input information saving file 2f are different contributes to security enhancement.

  The disk drive 25 reads information from an optical disk 2d such as a CD, DVD, BD or the like, which is an external storage medium, and records information on the optical disk 2d.

  The display unit 26 is a display device that displays an image. The display part 26 has screens, such as a liquid crystal display, an organic EL (Electro Luminescence) display, a CRT (Cathode Ray Tube) display, for example, and displays the various information which concerns on the program 2P on the said screen according to the instruction | indication from CPU21.

  The operation unit 27 is an input device such as a keyboard, a mouse, a touch panel, and a power switch on which a user performs various inputs. The operation unit 27 generates an input signal based on an operation by the user. The generated input signal is output to the CPU 21 via the bus 2b.

  The timer 28 is a device that counts a predetermined time by counting clocks. The timer 28 outputs the clocked result to the CPU 21.

  The communication unit 29 is a wired or wireless communication modem, a LAN card, a router, a USB (Universal Serial Bus) terminal, a connection connector, or the like. The communication unit 29 is connected to the network 1N.

  The CPU 21 may read the program 2P from the optical disk 2d via the disk drive 25. The CPU 21 may read the program 2P from an external information processing apparatus or storage device via the communication unit 29. Further, a semiconductor memory 2m such as a flash memory storing the program 2P may be mounted in the terminal device 20.

Next, functions of the terminal device 20 will be described.
FIG. 3 is a functional block diagram illustrating an example of functions of the terminal device 20. Each functional unit of the terminal device 20 is realized by the cooperation of the program 2P stored in the hard disk 24 and hardware resources such as the CPU 21, RAM 23, and hard disk 24. The terminal device 20 includes functional units such as a communication unit 201, a session management unit 202, a display control unit 203, a determination unit 204, a storage control unit 205, and a restoration unit 206.

  The communication unit 201 corresponds to the hardware communication unit 29 and is a functional unit that transmits and receives information to and from the web server 30 via the network 1N. The communication unit 201 transmits an acquisition request for a web page for registering personal information to the web server 30 (hereinafter referred to as an information registration page (input screen)). The communication unit 201 receives screen information on the information registration page from the web server 30. The screen information here includes an HTML document, an image file, an audio file, a CSS (Cascading Style Sheet) file, an XML (Extensible Markup Language) file, a script, and the like. Image files, audio files, and the like are associated with HTML documents. At that time, the communication unit 201 simultaneously receives web page identification information (hereinafter referred to as a screen ID), session identification information (hereinafter referred to as a session ID), and a session expiration date from the web server 30.

The session management unit 202 is a functional unit that manages a session with the web server 30.
The HTTP protocol does not provide a session management mechanism. Therefore, when the user transitions to a plurality of related web pages, the web server 30 shares the session ID issued by itself with the terminal device 20 to identify the terminal device 20 or the user and start a session. Information received from the device 20 is managed. In order to avoid wasting resource resources, the web server 30 ends the session and discards the session ID when the expiration date of the session has elapsed.

  The session management unit 202 stores the session ID and session expiration date received by the communication unit 201 in the cookie file 2c of the hard disk 24. The session management unit 202 adds a session ID and a screen ID of the information registration page to the input information when the communication unit 201 transmits the input information of the information registration page to the web server 30. Thereby, when the input information is received from the terminal device 20, the web server 30 can specify the terminal device 20 from the session ID and can specify the web page corresponding to the input information from the screen ID.

  In the case of a system that logs in and logs out, a user ID and a password may be used as session identification information instead of the session ID. Further, when the terminal device 20 is a mobile phone, the mobile phone browser does not support cookies, so that the mobile phone identification number (for example, a manufacturing number or serial number) may be used instead of the session ID. .

  The display control unit 203 is a functional unit that displays a web page, a pop-up screen, a message box, and the like on the display unit 26. The display control unit 203 displays the information registration page on the display unit 26 based on the screen information corresponding to the information registration page received by the communication unit 201 from the web server 30.

  FIG. 4 is an explanatory diagram showing an example of the screen layout of the information registration page 2p. The information registration page 2 p is a web page for inputting user personal information to be transmitted to the web server 30. The information registration page 2p includes a screen area of a basic information area 21ar, a history area 22ar and a self-PR area 23ar, and a transmission button 2btn. The basic information area 21ar, the history area 22ar, the self-PR area 23ar, and the send button 2btn are arranged in this order from the top to the bottom of the information registration page 2p.

The basic information area 21ar includes a text box for the user to input his / her name, date of birth, and the like, and a radio button for selecting and inputting gender.
The career area 22ar includes a text box for the user to input his / her history.
The self-PR area 23ar includes a text box for the user to input his / her strengths.
The send button 2btn is a button for sending the personal information input to the information registration page 2p to the web server 30.

Returning to FIG. 3, the description of the function of the terminal device 20 will be continued.
The determination unit 204 is a functional unit that determines whether or not the session expiration date has passed. The determination unit 204 determines whether or not the session expiration date has passed based on the session expiration date stored by the session management unit 202 in the cookie file 2c and the result of the timer 28 timing.

  The storage control unit 205 is a functional unit that stores the input information input by the user on the information registration page 2p in the input information save file 2f of the hard disk 24 when the determination unit 204 determines that the session expiration date has passed. . Specifically, the storage control unit 205 encrypts the HTML document of the information registration page 2p including the input information and the screen ID of the information registration page 2p, and stores them in the input information save file 2f.

  Even if the received HTML document is associated with an image file, an audio file, or the like, the storage control unit 205 writes only the HTML document including the input information and the image ID as a character string in the input information saving file 2f. Since image files, audio files, and the like generally have large capacities, this can reduce the storage capacity of the hard disk 24 and shorten the access time to the hard disk 24.

  If the user inputs all input information related to personal information on the information registration page 2p and presses the send button 2btn before the expiration date of the session elapses, the communication unit 201 inputs the input information, the session ID and the information registration page 2p. The screen ID is transmitted to the web server 30. Accordingly, the web server 30 registers the received input information in, for example, a database, and transmits screen information for notifying the user that the input information registration processing has been normally completed, to the terminal device 20. The display control unit 203 displays a notification screen corresponding to the screen information received by the communication unit 201 on the display unit 26. This is a normal case.

  However, since the web server 30 discards the session ID when the expiration date of the session has elapsed, the terminal device 20 or the user can be specified even if input information, a session ID, and the like are received from the terminal device 20. Therefore, the registration process cannot be executed. This is the case of an abnormal case. Accordingly, when the web server 30 receives input information or the like from the terminal device 20 after the expiration date of the session has elapsed, the web server 30 transmits error screen information for notifying the user of a session expiration date error to the terminal device 20. The display control unit 203 displays an error screen corresponding to the error screen information received by the communication unit 201 on the display unit 26. As a result, the user knows the session timeout.

  In the case of a web page having many input fields, such as the information registration page 2p, the user needs a long time to input, and therefore the frequency of expiration of the session is high before the input ends. The user who knows the session timeout from the error screen accesses the web server 30 again in order to display the information registration page 2p on the display unit 26 again. In response to the re-request for the information registration page 2p from the terminal device 20, the web server 30 transmits again the screen information, the screen ID, and the new session ID corresponding to the information registration page 2p to the terminal device 20. The communication unit 201 receives again the screen information, the screen ID, and the new session ID corresponding to the information registration page 2p from the web server 30.

  The restoration unit 206 is a functional unit that restores the information registration page 2p corresponding to the screen information received again from the web server 30 to the state when the storage control unit 205 stores the input information in the input information save file 2f. Alternatively, the restoration unit 206 reads the HTML document of the information registration page 2p received again from the web server 30, and the HTML document of the information registration page 2p at the time when the storage control unit 205 stores the input information in the input information save file 2f. It is a functional part that restores to When the communication unit 201 receives again the screen information (including the HTML document) corresponding to the information registration page 2p from the web server 30, the restoration unit 206 receives the encrypted HTML document and the screen ID from the input information save file 2f. The read HTML document and the screen ID are decrypted. The restoration unit 206 compares the decrypted HTML document with the HTML document received again.

  FIG. 5 is an explanatory diagram showing a comparison between the HTML document stored in the input information saving file 2f and the HTML document received again. The left side of FIG. 5 shows a part of the HTML document stored in the input information saving file 2f. The right side of FIG. 5 shows a part of the HTML document received again. In the HTML document stored in the input information saving file 2f, a portion corresponding to the input column for personal information is indicated by a solid line. Also, in the HTML document received again, the portion corresponding to the personal information input field is indicated by a broken line.

  The restoration unit 206 compares the stored HTML document and the HTML document received again, line by line from the first line to the last line, and extracts a difference. As a result, the restoration unit 206 extracts, for example, a portion surrounded by a solid line as a difference in the HTML document stored in the input information save file 2f on the left side of FIG. The restoration unit 206 embeds the extracted difference in the HTML document received again, and completes the restoration of the HTML document on the information registration page 2p.

  The display control unit 203 displays the information registration page 2p related to the HTML document restored by the restoration unit 206 on the display unit 26. As a result, the user can restart the input operation from the input state at the time when the previous session timed out, instead of starting the input to the information registration page 2p from the beginning.

  When the user finishes inputting the input information on the information registration page 2p and presses the send button 2btn before the expiration date of the new session elapses, the communication unit 201 sends the input information to the web server 30 and the screen of the information registration page 2p. Send ID and new session ID. When the transmission within the validity period of this session is completed, the storage control unit 205 deletes the input information save file 2 f from the hard disk 24.

  Since the input information saving file 2 f is independent of the cookie, the input information saving file 2 f remains in the hard disk 24 even if the browser is closed or the terminal device 20 is shut down unless deleted by the storage control unit 205. Accordingly, the restoration unit 206 can reliably restore the information registration page 2p even when a shortage occurs.

Next, the operation of the terminal device 20 will be described.
6 and 7 are flowcharts illustrating an example of the procedure of the restoration process. The restoration process is a process executed by the terminal device 20 and the web server 30 every time a user newly accesses the web server 30.

  The CPU 21 receives access to the web server 30 from the operation unit 27 (step S101). CPU21 transmits the request | requirement of the screen information corresponding to the information registration page 2p to the web server 30 (step S102).

  The web server 30 receives a request for screen information corresponding to the information registration page 2p from the terminal device 20 (step S103). The web server 30 transmits the HTML document, screen ID, session ID, and session expiration date of the information registration page 2p to the terminal device 20 (step S104). In step S104, when an image file or the like is associated with the HTML document on the information registration page 2p, the web server 30 also transmits the image file or the like to the terminal device 20. Hereinafter, it is assumed that the image information is only an HTML document.

  The terminal device 20 receives the HTML document, screen ID, session ID, and session expiration date of the information registration page 2p from the web server 30 (step S105). The CPU 21 writes the received session ID and session expiration date in the cookie file 2c of the hard disk 24 (step S106). Based on the result of the timer 28, the CPU 21 starts counting down toward the time when the session ends (step S107).

  The CPU 21 determines whether or not the input information saving file 2f is stored in the hard disk 24 (step S108). The input information save file 2f is created by the save process shown in FIG. When the CPU 21 determines that the input information saving file 2f is not stored in the hard disk 24 (step S108: NO), the CPU 21 displays the received HTML document information registration page 2p on the display unit 26 (step S109). The CPU 21 executes the save process shown in FIG. 8 (step 110) and ends the process.

  If the CPU 21 determines that the input information save file 2f is stored in the hard disk 24 (step S108: YES), it reads the contents of the input information save file 2f to the RAM 23 (step S111). The CPU 21 decrypts the content of the input information saving file 2f read to the RAM 23 (step S112). The CPU 21 reads the received HTML document of the information registration page 2p into the RAM 23 (step S113).

  The CPU 21 compares the HTML document (including input information) written in the decrypted input information save file 2f with the received HTML document of the information registration page 2p, and extracts the difference (step S114). The CPU 21 embeds the extracted difference in the received HTML document (step S115). That is, the CPU 21 restores the received HTML document of the information registration page 2p to the state when the input information is written in the input information saving file 2f. The CPU 21 displays the restored information registration page 2p on the display unit 26 based on the HTML document in which the difference is embedded (step S116), and moves the process to step S110.

  FIG. 8 is a flowchart illustrating an example of the procedure of the saving process. The saving process includes a process in which the terminal device 20 writes the input information input to each input field of the information registration page 2p into the input information saving file 2f. The saving process includes a process in which the terminal device 20 deletes the input information saving file 2f when the terminal device 20 transmits input information to the web server 30 within the expiration date of the session. Further, the saving process includes a process of registering the input information of the information registration page 2p received by the web server 30 from the terminal device 20.

  The CPU 21 determines whether or not the countdown started in step S107 has ended (step S201). If the CPU 21 determines that the countdown started in step S107 has ended (step S201: YES), the CPU 21 determines whether or not the input information save file 2f is stored in the hard disk 24 (step S202). If the CPU 21 determines that the input information saving file 2f is stored in the hard disk 24 (step S202: YES), the CPU 21 proceeds to step S205.

  If the CPU 21 determines that the input information save file 2f is not stored in the hard disk 24 (step S202: NO), the CPU 21 creates an empty input information save file 2f (step S203). The CPU 21 stores the created input information save file 2f in the hard disk 24 (step S204). The CPU 21 encrypts the HTML document of the information registration page 2p including the input information and the screen ID of the information registration page 2p (step S205). The CPU 21 associates the encrypted HTML document and the screen ID, writes them in the input information save file 2f (step S206), and ends the process. In step S206, the CPU 21 opens the input information save file 2f in the write mode, and closes the input information save file 2f after writing.

  When it is determined that the countdown started in step S107 has not ended (step S201: NO), the CPU 21 determines whether or not the transmission button 2btn on the information registration page 2p has been pressed (step S207). If the CPU 21 determines that the send button 2btn on the information registration page 2p has not been pressed (step S207: NO), it returns the process to step S207. If the CPU 21 determines that the send button 2btn of the information registration page 2p has been pressed (step S207: YES), the web server 30 uses the input information input to the information registration page 2p, the screen ID and the session ID of the information registration page 2p. (Step S208). The CPU 21 deletes the input information save file 2f from the hard disk 24 (step S209).

  The web server 30 receives the input information input from the terminal device 20 to the information registration page 2p, the screen ID and the session ID of the information registration page 2p (step S210). The web server 30 executes a registration process for registering the received input information (step S211). The web server 30 transmits the HTML document, the screen ID, and the session ID of the notification screen that notifies the end of the registration process to the terminal device 20 (step S212).

  The CPU 21 receives the HTML document, the screen ID, and the session ID of the notification screen for notifying that the registration process has been completed from the web server 30 (step S213). CPU21 displays the notification screen of the HTML document received from the web server 30 on the display part 26 (step S214), and complete | finishes a process.

  In the above example, the online system 10 deals with a case where information is newly registered from the terminal device 20 to the web server 30. However, it goes without saying that the online system 10 may handle a case where information is updated and registered from the terminal device 20 to the web server 30. For example, even when the input information including the changed content is transmitted from the terminal device 20 to the web server 30 in order to change the content input by the user on the information registration page 2p, the restoration processing and the saving processing can be applied as they are. .

In the above example, the timing for writing the input information to the information registration page 2p in the input information saving file 2f is after the expiration date of the session has elapsed. However, the timing at which the input information to the information registration page 2p is written to the input information saving file 2f may be when the session expiration date has passed, or at a certain time before the session expiration date. The certain time here is, for example, several minutes when the effective period of the session is 1 hour, for example. Further, the certain time here is, for example, ˜several tens of seconds when the valid period of the session is 10 minutes, for example. In other words, a time point a certain time before the time point at which the expiration date elapses is a time point corresponding to a certain proportion of time with respect to the period from the start of the countdown until the expiration date elapses. In order to set or change the timing for writing the input information to the input information saving file 2f, in the process of determining the end of the countdown (step S201), the time point at which the countdown ends may be changed as appropriate.
By writing the input information to the input information saving file 2f before the session times out, even if an unexpected situation (for example, shutdown of the web server 30 or the terminal device 20) occurs within the expiration date of the session The screen can be restored.

  In the above example, the terminal device 20 restored the information registration page 2p using all of the input information saved in the input information save file 2f. However, the terminal device 20 may restore the information registration page 2p using a part of the input information stored in the input information saving file 2f. For example, it is assumed that the session expiration date has passed while the user started to input to the basic information area 21ar from the upper part of the information registration page 2p and input to the history area 22ar. In such a case, the terminal device 20 stores the input information input by the user in the basic information area 21ar and the history area 22ar in the input information saving file 2f. At the time of restoration, the terminal device 20 may restore the information registration page 2p using only the input information input to the basic information area 21ar among the input information stored in the input information saving file 2f. Alternatively, it is assumed that the session expiration date has elapsed when the user starts to input to the self-PR area 23ar. In such a case, the terminal device 20 stores the input information input by the user in the basic information area 21ar, the history area 22ar, and the self-PR area 23ar in the input information saving file 2f. At the time of restoration, the terminal device 20 may restore the information registration page 2p using only the input information input to the basic information area 21ar and the history area 22ar among the input information stored in the input information saving file 2f.

In the above-described example, the input information save file 2f is deleted after the input information is transmitted to the web server 30 within the session expiration date. However, when the input information save file 2f is deleted, the information registration page 2p newly displayed on the display unit 26 when the user accesses the web server 30 again is restored using the contents of the input information save file 2f. After you do.
After the information registration page 2p is restored, even if the input information save file 2f is deleted, the user can avoid loss of input information. Further, the remaining storage capacity of the hard disk 24 can be increased earlier by deleting the input information saving file 2f earlier than the time when the input information is transmitted.

According to the terminal device 20, the input screen can be restored even if the expiration date of the session with the web server has elapsed.
When the input information on the input screen is transmitted from the terminal device 20 to the web server 30 after the session has timed out, the web page displayed on the browser screen transitions to an error screen with an expiration date. When the user accesses the web server 30 again and redisplays the initial input screen on the browser screen, the input information that has already been input is lost. However, the terminal device 20 retains the input information even after the expiration date of the session has elapsed by saving the input information in the input information saving file 2f. When the user accesses the web server 30 again, the terminal device 20 can restore the input screen in the initial state to the input state at the time when the expiration date has passed and display it on the browser screen.

  Note that the user can display the information registration page 2p that is in the middle of input or input completion cached by the browser by pressing the return button of the browser. However, to re-establish a session that has timed out, the user must access the web server 30 again. When the user accesses the web server 30 again, the web server 30 transmits screen information corresponding to the information registration page 2p in the initial state to the terminal device 20 together with the new session ID. For this reason, the information registration page 2p that is in the middle of input or in the state of completion of input transitions to the information registration page 2p in the initial state, and therefore the loss of input information cannot be avoided with the return button of the browser.

The input information input by the user on the input screen can be held by, for example, a web server. However, even if a specific web server is provided with a function for holding input information, other web servers still lose input information.
The terminal device 20 stores input information related to a session with any web server in its own hard disk 24. Therefore, the terminal device 20 can restore the input screen to the input state at the time when the expiration date has passed even if the expiration date of the session with an arbitrary web server has elapsed.

There are other advantages that the terminal device 20 holds the input information than the web server holds the input information.
In order to provide an input information holding function and an input screen restoration function for each web page of all web servers, a large amount of money is required.
However, the program 2P for executing the saving process and the restoring process in the terminal device 20 can be provided as add-on software for an existing browser, and the program 2P can be installed and distributed at a low cost.

When the web server holds the input information, the input information must be sequentially transmitted from the terminal device to the web server, and a communication load is applied to the terminal device, the web server, and the network each time this communication is performed.
However, since the terminal device 20 holds the input information therein, the terminal device 20 does not apply any load related to the communication process of the input information to the web server 30 and the network 1N. Also, the terminal device 20 itself is released from the communication load for transmitting input information to the web server 30.

In general, the number of terminal devices with which one web server establishes a session is far greater than the number of web servers with which one terminal device establishes a session.
The web server generates 100 files or instances related to the session when 100 sessions are established, and 100,000 files or instances related to the session when 100,000 sessions are established. Is generated. The web server holds and manages input information through a file or instance related to the generated session. Therefore, when the web server holds the input information, the resource resources of the web server are used as many as the number of sessions, and the load on the web server increases.
However, since the terminal device 20 holds the input information therein, the terminal device 20 does not place a load on the web server 30 regarding the holding and management of the input information. Further, the load applied to the terminal device 20 for holding the input information is much smaller than when the web server holds the input information.

Embodiment 2
The second embodiment relates to a mode in which the user selects input information for restoring the information registration page 2p.
In the second embodiment, the same reference numerals are assigned to the same components as those in the first embodiment, and detailed description thereof is omitted.

  When the send button 2btn on the information registration page 2p is pressed within the session expiration date, the CPU 21 deletes the input information save file 2f. However, if the user does not press the send button 2btn within the expiration date of the session, the input information saving file 2f remains on the hard disk 24. In this state, when the user re-accesses the web server 30 many times and inputs input information from the information registration page 2p, and each session expires, a plurality of HTML documents are stored in the input information saving file 2f. Will be accumulated.

  Therefore, in the second embodiment, the CPU 21 associates the HTML document including the input information with the screen ID and writes it in the input information save file 2f together with the save date and time. The CPU 21 displays on the display unit 26 a selection screen for allowing the user to select input information used for restoration when the information registration page 2p is restored. The CPU 21 restores the information registration page 2p using the input information selected by the user from the selection screen.

  FIG. 9 is an explanatory diagram showing an example of the screen layout of the selection screen 2s. The selection screen 2s is displayed as a pop-up screen, for example, in front of the information registration page 2p. On the upper left of the selection screen 2s, the screen ID of the web page and the name of the web page are displayed. In FIG. 9, three pieces of input information regarding the self-PR of the information registration page 2p are illustrated. The contents of the input fields other than the self-PR are not displayed on the selection screen 2s, assuming that all three pieces of input information are the same. For example, when the contents of all the input fields are different for all three pieces of input information, the input information related to all the input fields is displayed on the selection screen 2s.

  The selection screen 2s includes input information labels 21l, 22l, and 23l and selection buttons 21btn, 22btn, and 23btn. Input information is displayed on the input information labels 21l, 22l, and 23l. In addition, at the head of the input information labels 21l, 22l, and 23l, the storage time of the input information is displayed in, for example, yyyy / MM / dd HH: mm: ss format. When the size of the input information labels 21l, 22l, and 23l is smaller than the information amount of the input information, a scroll bar is displayed at the right end. On the right side of each input information label 21l, 22l, 23l, selection buttons 21btn, 22btn, 23btn corresponding to the respective input information are displayed. The selection buttons 21btn, 22btn, and 23btn are buttons for the user to select input information used for restoring the information registration page 2p. The CPU 21 specifies input information from the pressed selection buttons 21btn, 22btn, and 23btn, and restores the information registration page 2p with the specified input information.

  10 and 11 are flowcharts illustrating an example of the procedure of the restoration process. Note that the restoration process according to the second embodiment includes steps S101 to S107 in the restoration process of FIGS. 10 and 11 show processing subsequent to the processing (step S301) corresponding to step S108 in FIG.

  The CPU 21 determines whether or not the input information saving file 2f is stored in the hard disk 24 (step S301). When the CPU 21 determines that the input information saving file 2f is not stored in the hard disk 24 (step S301: NO), the CPU 21 displays the received HTML document information registration page 2p on the display unit 26 (step S302). The CPU 21 executes the save process shown in FIG. 11 (step 303) and ends the process.

  If the CPU 21 determines that the input information save file 2f is stored in the hard disk 24 (step S301: YES), it reads the contents of the input information save file 2f to the RAM 23 (step S304). The CPU 21 decrypts the contents of the input information saving file 2f read to the RAM 23 (step S305). The CPU 21 determines whether or not the content of the decrypted input information saving file 2f includes an HTML document (including input information) corresponding to the received screen ID (step S306). If the CPU 21 determines that the decrypted input information save file 2f does not include an HTML document (including input information) corresponding to the received screen ID (step S306: NO), the information registration page 2p Is displayed on the display unit 26 (step S302). The save process shown in FIG. 11 is executed (step 303), and the process ends.

  If the CPU 21 determines that the HTML document corresponding to the received screen ID is included in the content of the decrypted input information saving file 2f (step S306: YES), the CPU 21 stores the received HTML document of the information registration page 2p. Reading to the RAM 23 (step S307). The CPU 21 extracts one or more combinations of the HTML document (including input information) and the storage time corresponding to the received screen ID from the content of the decrypted input information save file 2f (step S308). The CPU 21 generates the selection screen 2s based on the combination of the extracted HTML document (including input information) and the storage time (step S309).

  The CPU 21 displays the information registration page 2p of the received HTML document and the generated selection screen 2s on the display unit 26 in a state where the selection screen 2s is arranged in front of the information registration page 2p (step S310). The CPU 21 determines whether any one of the selection buttons 21btn, 22btn, and 23btn has been pressed (step S311). If the CPU 21 determines that none of the selection buttons 21btn, 22btn, and 23btn has been pressed (step S311: NO), the process returns to step S311.

  When the CPU 21 determines that any one of the selection buttons 21btn, 22btn, and 23btn is pressed (step S311: YES), the HTML document includes input information corresponding to the pressed selection buttons 21btn, 22btn, and 23btn. Is identified (step S312). The CPU 21 compares the identified HTML document with the received HTML document of the information registration page 2p, and extracts the difference (step S313). The CPU 21 embeds the extracted difference in the received HTML document (step S314). The CPU 21 displays the restored information registration page 2p on the display unit 26 based on the HTML document in which the difference is embedded (step S315), and moves the process to step S303.

FIG. 12 is a flowchart illustrating an example of the procedure of the saving process.
The CPU 21 determines whether or not the countdown started in step S107 has ended (step S401). If the CPU 21 determines that the countdown started in step S107 has ended (step S401: YES), the CPU 21 determines whether or not the input information save file 2f is stored in the hard disk 24 (step S402). If the CPU 21 determines that the input information save file 2f is stored in the hard disk 24 (step S402: YES), the CPU 21 proceeds to step S405.

  When the CPU 21 determines that the input information save file 2f is not stored in the hard disk 24 (step S402: NO), the CPU 21 creates an empty input information save file 2f (step S403). The CPU 21 stores the created input information save file 2f in the hard disk 24 (step S404). Note that steps S403 and S404 are performed only when the save process is first executed.

  The CPU 21 encrypts the HTML document of the information registration page 2p including the input information and the screen ID of the information registration page 2p (step S405). The CPU 21 associates the encrypted HTML document and screen ID with the current date and time counted by the timer 28, writes them in the input information save file 2f (step S406), and ends the process. The current date and time in step S406 is the save date and time when the input information is saved in the input information save file 2f. In step S406, the CPU 21 opens the input information save file 2f in the add mode, closes the input information save file 2f after additional writing.

  If the CPU 21 determines that the countdown started in step S107 has not ended (step S401: NO), the CPU 21 determines whether the transmission button 2btn on the information registration page 2p has been pressed (step S407). If the CPU 21 determines that the send button 2btn on the information registration page 2p has not been pressed (step S407: NO), it returns the process to step S407. If the CPU 21 determines that the send button 2btn of the information registration page 2p has been pressed (step S407: YES), the web server 30 uses the input information input to the information registration page 2p, the screen ID and session ID of the information registration page 2p. (Step S408).

  The CPU 21 deletes the HTML document, the screen ID (these are encrypted) including the input information corresponding to the transmitted screen ID, and the save date and time from the input information save file 2f (step S409). In step S409, if one or more HTML documents including the input information corresponding to the transmitted screen ID, the screen ID, and the storage time are stored in the input information saving file 2f, all of them are deleted. That is, in step S409, all information used to generate the selection screen 2s is deleted from the input information save file 2f. As described above, in the second embodiment, the input information saving file 2f is not deleted. Information used for selecting the input information is deleted from the input information saving file 2f. There is a possibility that a plurality of HTML documents including input information input on a plurality of different input screens are written in the input information saving file 2f. Therefore, in order not to delete the HTML document of the input screen that is not used for restoration from the input information save file 2f, the HTML document, the screen ID, and the storage time are displayed in units of screen IDs corresponding to the input information that has been transmitted. Delete with.

  The web server 30 receives the input information input from the terminal device 20 to the information registration page 2p, the screen ID and the session ID of the information registration page 2p (step S410). The web server 30 executes a registration process for registering the received input information (step S411). The web server 30 transmits the HTML document, the screen ID, and the session ID of the notification screen that notifies the end of the registration process to the terminal device 20 (step S412).

  The CPU 21 receives the HTML document, the screen ID, and the session ID of the notification screen for notifying that the registration process has been completed from the web server 30 (step S413). The CPU 21 displays a notification screen of the HTML document received from the web server 30 on the display unit 26 (step S414), and ends the process.

According to the terminal device 20, the input screen can be restored using the input information selected by the user.
When the user repeatedly inputs input information multiple times on the same input screen, and the expiration date of the session elapses each time, the input information save file 2f stores a plurality of input information corresponding to the same screen ID. Is done. When a plurality of pieces of input information corresponding to the same screen ID are stored, when the input screen is restored, the terminal device 20 restores the input screen using, for example, the most recently saved input information. However, the input screen restored according to the predetermined specification is not always optimal for the user.
Since the terminal device 20 restores the input screen using the input information selected by the user, the most desirable input information for the user is reproduced on the restored input screen.

Embodiment 3
The third embodiment relates to a mode in which input information input to the information registration page 2p is stored in the input information saving file 2f every time an event occurs in the terminal device 20.
In the third embodiment, the same reference numerals are assigned to the same components as those in the first and second embodiments, and detailed description thereof is omitted.

When a terminal processor 20 is used to activate a word processor, spreadsheet software, or other software for a long time input operation, the user usually saves input information on the hard disk 24 on a small basis. This is to avoid loss of input information in preparation for a problem that occurs in the terminal device 20, software, work environment, etc. during the input work.
On the other hand, in the case of the on-line system 10, even when the amount of input information or the number of input items is large, information input by the user on the web page is not stored in the hard disk 24. Even if the information input to the web page is saved in the hard disk 24 in some file format, when the saved information is restored to the web page, the user has to repeat copy and paste, which is complicated.

  Therefore, in the third embodiment, the CPU 21 associates the HTML document including the input information at regular time intervals with the screen ID while the information registration page 2p is displayed on the display unit 26, and the input information saving file 2f. Save over. When the user re-accesses the web server 30 after the expiration date of the session has elapsed, the CPU 21 restores the information registration page 2p with the contents of the input information save file 2f. When the CPU 21 transmits the input information and the screen ID to the web server 30 within the validity period of the session, the CPU 21 deletes the input information and the information corresponding to the screen ID from the input information save file 2f.

  FIG. 13 is a functional block diagram illustrating an exemplary function of the terminal device 20. Each functional unit of the terminal device 20 is realized by the cooperation of the program 2P stored in the hard disk 24 and hardware resources such as the CPU 21, RAM 23, and hard disk 24.

The terminal device 20 includes a timing event generation unit 207 and an update storage control unit 208.
The timed event generating unit 207 detects the date and time counted by the timer 28, and generates a timer event at regular time intervals.

  While the display control unit 203 displays the information registration page 2p on the display unit 26, the update storage control unit 208 updates the input information input by the user on the information registration page 2p to the input information save file 2f at regular time intervals. It is a functional part to memorize. The update storage control unit 208 encrypts the HTML document of the information registration page 2p including the input information and the screen ID of the information registration page 2p at regular time intervals based on the timer event generated by the timing event generation unit 207. To do. The update storage control unit 208 updates and stores the encrypted HTML document and the screen ID in the input information save file 2 f stored in the hard disk 24 at regular time intervals based on the timer event generated by the timing event generation unit 207. .

  When the user finishes inputting the input information on the information registration page 2p and presses the send button 2btn before the expiration date of the new session elapses, the communication unit 201 sends the input information to the web server 30 and the screen of the information registration page 2p. Send ID and new session ID. When transmission within the validity period of this session is completed, the update storage control unit 208 deletes the HTML document and the screen ID (encrypted) including the transmitted input information from the input information save file 2f. .

  14 and 15 are flowcharts showing an example of the procedure of the restoration process. Note that the restoration process according to the third embodiment includes steps S101 to S107 in the restoration process of FIGS. 14 and 15 show processing subsequent to the processing (step S501) corresponding to step S108 in FIG.

  The CPU 21 determines whether or not the input information saving file 2f is stored in the hard disk 24 (step S501). If the CPU 21 determines that the input information saving file 2f is not stored in the hard disk 24 (step S501: NO), the CPU 21 displays the received HTML document information registration page 2p on the display unit 26 (step S502). The CPU 21 executes the save process shown in FIGS. 16 and 17 (step 503) and ends the process.

  If the CPU 21 determines that the input information save file 2f is stored in the hard disk 24 (step S501: YES), it reads the contents of the input information save file 2f to the RAM 23 (step S504). The CPU 21 decrypts the content of the input information saving file 2f read to the RAM 23 (step S505).

  The CPU 21 determines whether or not the content of the decrypted input information saving file 2f includes an HTML document (including input information) corresponding to the received screen ID (step S506). When the CPU 21 determines that the HTML document corresponding to the received screen ID is not included in the content of the decrypted input information saving file 2f (step S506: NO), the information registration page 2p is displayed on the display unit 26. (Step S502). The save process shown in FIGS. 16 and 17 is executed (step 503), and the process ends.

  If the CPU 21 determines that the HTML document corresponding to the received screen ID is included in the content of the decrypted input information saving file 2f (step S506: YES), the CPU 21 stores the received HTML document of the information registration page 2p. Reading to the RAM 23 (step S507). The CPU 21 extracts an HTML document (including input information) corresponding to the received screen ID from the content of the decrypted input information saving file 2f (step S508).

  The CPU 21 compares the extracted HTML document with the received HTML document of the information registration page 2p, and extracts the difference (step S509). The CPU 21 embeds the extracted difference in the received HTML document (step S510). The CPU 21 displays the information registration page 2p on the display unit 26 based on the HTML document in which the difference is embedded (step S511), and moves the process to step S503.

16 and 17 are flowcharts illustrating an example of the procedure of the save process.
The CPU 21 determines whether or not the input information saving file 2f is stored in the hard disk 24 (step S601). If the CPU 21 determines that the input information saving file 2f is stored in the hard disk 24 (step S601: YES), the CPU 21 advances the process to step S608.

  If the CPU 21 determines that the input information save file 2f is not stored in the hard disk 24 (step S601: NO), the CPU 21 creates an empty input information save file 2f (step S602). The CPU 21 stores the created input information save file 2f in the hard disk 24 (step S603). Note that steps S603 and S604 are performed only when the saving process is first executed.

  The CPU 21 encrypts the HTML document of the information registration page 2p including the input information and the screen ID of the information registration page 2p (step S604). The CPU 21 opens the input information save file 2f in the update mode (step S605). The CPU 21 updates the encrypted HTML document of the information registration page 2p and the screen ID in association with each other (step S606). The CPU 21 closes the input information save file 2f (step S607).

  The CPU 21 determines whether or not a fixed time has elapsed based on the result of the timer 28 (step S608). Step S608 corresponds to the function of the timing event generation unit 207 in FIG. If the CPU 21 determines that a certain time has elapsed (step S608: YES), it returns the process to step S604. While displaying the information registration page 2p on the display unit 26, the CPU 21 repeats Steps S604 to S607 at regular time intervals.

  It should be noted that an event program that outputs a constant signal to the CPU 21 when a certain period of time has elapsed based on the time measured by the timer 28 may be created, and the process of step S608 may be executed. In such a case, in step S608, the CPU 21 determines whether or not a certain signal is input from the newly created program.

  In step S606, when the already encrypted information is written in the input information saving file 2f, the CPU 21 decrypts the encrypted information and writes the input information related to the same screen ID in the input information saving file 2f. It is determined whether or not. When the CPU 21 determines that the input information related to the same screen ID is written in the input information save file 2f, the CPU 21 writes the encrypted HTML document and the screen ID in the input information save file 2f in the overwrite mode. When the CPU 21 determines that the input information related to the same screen ID is not written in the input information save file 2f, the CPU 21 writes the encrypted HTML document and the screen ID in the input information save file 2f in the insertion mode.

  Since step S606 is repeated at regular time intervals, decryption of the encrypted information may have a heavy load. In such a case, the CPU 21 encrypts only the HTML document in step S604, and writes the HTML document of the information registration page 2p encrypted in step S605 and the unencrypted screen ID in association with each other in the input information saving file 2f. When the input information related to the same screen ID is written in the input information save file 2f using the screen ID as a key, the CPU 21 uses the input information related to the same screen ID in the input information save file 2f in the overwrite mode. If not written, the encrypted HTML document and the unencrypted screen ID are written in the input information saving file 2f in the insertion mode.

  When determining that the certain time has not elapsed (step S608: NO), the CPU 21 determines whether or not the countdown started in step S107 has ended (step S609). If the CPU 21 determines that the countdown started in step S107 has ended (step S609: YES), it returns the process to step S608. If the CPU 21 determines that the countdown started in step S107 has not ended (step S609: NO), the CPU 21 determines whether the transmission button 2btn on the information registration page 2p has been pressed (step S610).

  If the CPU 21 determines that the send button 2btn on the information registration page 2p has not been pressed (step S610: NO), it returns the process to step S608. If the CPU 21 determines that the send button 2btn on the information registration page 2p has been pressed (step S610: YES), the web server 30 uses the input information input to the information registration page 2p, the screen ID and the session ID of the information registration page 2p. (Step S611). The CPU 21 deletes the transmitted input information and information corresponding to the screen ID from the input information save file 2f (step S612).

  The web server 30 receives the input information input from the terminal device 20 to the information registration page 2p, the screen ID and the session ID of the information registration page 2p (step S613). The web server 30 executes a registration process for registering the received input information (step S614). The web server 30 transmits the HTML document and the screen ID of the notification screen for notifying information according to the result of the registration process to the terminal device 20 (step S615). If the session has not timed out in step S615, the notification screen is a screen for notifying that the registration process has been completed normally, and the web server 30 also transmits the session ID. On the other hand, if the session has timed out in step S615, the notification screen is a screen for notifying a session time-out error.

  The CPU 21 receives an HTML document and a screen ID of a notification screen for notifying information corresponding to the result of the registration process from the web server 30 (step S616). If the session has not timed out in step S616, the CPU 21 also receives the session ID. The CPU 21 displays a notification screen of the HTML document received from the web server 30 on the display unit 26 (step S617), and ends the process.

  In the above example, the terminal device 20 updates and stores the input information input to the information registration page 2p in the input information save file 2f based on timer events that occur at regular time intervals. However, the terminal device 20 may update and store the input information input to the information registration page 2p in the input information save file 2f in response to an event other than the timer event. The event other than the timer event is an event that occurs when, for example, a keyboard key included in the operation unit 27 is pressed, a mouse button is clicked, or a touch panel is tapped. Alternatively, an event other than a timer event is an event that occurs when, for example, an active input field on the information registration page 2p moves to another input field, or when the content of the input field on the information registration page 2p is changed. .

In the above-described example, the terminal device 20 inputs the input information input to the information registration page 2p based on the timer event that occurs at regular time intervals while the information registration page 2p is displayed on the display unit 26. Updated and saved in the save file 2f. Therefore, when the user closes the browser, the save process is not executed. However, even when the browser is activated, the user may access a website other than the website of the web server 30 and start browsing web pages of the other website. Alternatively, it is conceivable that the user interrupts the input work on the information registration page 2p, starts other software other than the browser, and starts other work. In such a case, repeating the update storage of the input information in the saving process may put an excessive load on the terminal device 20.
Therefore, when the active web page moves from the information registration page 2p to another web page, the CPU 21 temporarily stops the saving process, and when the active web page moves from another web page to the information registration page 2p, The evacuation process may be resumed. On the other hand, when the active screen is moved from the browser information registration page 2p to another software screen, the CPU 21 temporarily stops the saving process, and the active screen is transferred from the other software screen to the browser information registration page 2p. When moved, the evacuation process may be resumed. In the latter case, the CPU 21 determines an active screen change between the browser and other software based on an event generated by an OS (Operating System).

According to the terminal device 20, the input screen can be restored regardless of the session timeout.
The terminal device 20 updates and saves the input information input to the information registration page 2p at regular time intervals in the input information save file 2f without depending on the session expiration date. As a result, the input information remains in the hard disk 24 even if a failure occurs in the terminal device 20, the web server 30, the network 1N, or the browser regardless of the session expiration date. Even if the user closes the browser for his own convenience, the input information remains on the hard disk 24. When the user re-accesses the web server 30, the terminal device 20 can restore the information registration page 2p with the contents updated and saved in the input information save file 2f. Thereby, the terminal device 20 can reduce the re-input work to the information registration page 2p.

  Since the terminal device 20 overwrites and saves input information and the like in the input information save file 2f at regular time intervals, a plurality of input information for the same web page is saved in the input information save file 2f as in the second embodiment. It will never be done. Therefore, the terminal device 20 does not need to allow the user to select input information used for restoration.

The web server cannot identify the terminal device unless it is within the session expiration date. Therefore, when the web server stores the input information, the timing at the time of storage is limited before the session is terminated. Therefore, when the web server stores the input information, the web server does not retain the input information input by the user after the session has expired, and cannot restore the input screen to a state after the session has expired. .
However, the terminal device 20 stores the input information in the hard disk 24 regardless of the session timeout. Therefore, the terminal device 20 can restore the input screen to the state at the time when the web server cannot restore.
