Description

The present invention relates to an input reduction method in a computer system using a personal computer or the like, and is particularly suitable for performing an input operation when security is required. Is.

[Prior Art] In a computer system that conventionally uses a personal computer or a host computer, in order to reduce the input operation of commands or data,
A data processing device having a so-called automatic input mechanism (method) has been considered. In a data processing device equipped with such an automatic input mechanism, commands or data required for data processing are collectively input, or response data prepared in advance in response to a message from the system is output. Has been.

For example, JP-A-59-200362 and JP-A-56-162123.
In the data gazette of the publication, in a data processing device provided with an input device, a central processing unit, and a display device, a means for extracting trigger data from a message from the central processing unit, and an automatic input data corresponding to the trigger data are triggered. Storage means for storing the data in association with the data, and determination means for determining whether the trigger data in the message matches the trigger data in the storage means,
There is described a technique provided with means for outputting to the central processing unit automatic input data corresponding to the trigger data from the storage means by the coincidence determination of the determination means.

[Problems to be Solved by the Invention] In the above-described conventional data processing device equipped with an automatic input mechanism, there is a lack of sufficient consideration in the input of data such as a password to be protected. There is still a possibility that the password will be checked only by the partner system, so there is a difficulty that each operator has a password locally and cannot freely register and repair it. .

An object of the present invention is to provide a data processing device which can be easily and flexibly modified for security protection and has an automatic input mechanism which requires a minimum number of input operations.

[Means for Solving Problems] The above-mentioned object is to make data for triggering automatic input possible not only by a message from a partner system but also by input data inputted by an operator, and the triggering data ( The message from the partner system and the data input by the operator) and the automatically input data are registered in advance in the storage area, and it is checked whether there is a relationship between the trigger data and the display content. This is achieved by processing the data automatically input according to the result as if it were input from the input device.

[Operation] In the present invention, the data that is automatically input is not only the message from the partner system but also the data input by the operator, which is triggered.

Therefore, if data that does not occur in the partner system is registered in the trigger data, the automatic input is not performed unless the registered data is input by the operator.

By registering a local password for each operator in the trigger data in this way, security can be protected.

In addition, this local password can be corrected and registered very easily because it can be done only on the personal computer side.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

 First, a first embodiment of the present invention will be described.

FIG. 1 shows an example of a computer system including a host computer 100 and a personal computer 200 which constitute a data processing apparatus, and a command, data or various messages are exchanged between them by a data line.
Further, the personal computer 200 includes a main body 210 having a built-in central processing unit, a display 221 and a text RAM for storing data to be displayed on the display 221.
(Random Access Memory) 222 and a display device 220,
For example, an input device 230 of a typewriter type for inputting various commands and data, an external storage device 240 for storing various data, and the like are configured. Of course, various interface circuits and main memory are arranged in the main body 210, and the main memory further includes a second memory.
Programs of various levels as shown in the figure are loaded. That is, briefly explaining this with reference to FIG.
213 is an OS that determines the personality of the personal computer 200
(Operating System), 211 and 212 are a display device interface program and a keyboard data acquisition program that operate under the control of the OS 213, and these lower-level input / output operation programs are usually BIOS (Basic Input Ou).
tput System) is also called. Reference numeral 214 denotes an application program that operates on the OS 213, and in the embodiment, the personal computer 200 is used as the host computer 1
A communication program for use as a terminal device of 00 is loaded. Reference numeral 215 denotes an automatic input / output program for realizing an automatic input operation, which is a characteristic part of the embodiment apparatus. As is clear from the figure, this automatic input / output program 215 is mainly used for loading the OS 213 and keyboard data. It is located between the programs 212 and performs necessary processing for signals (data) exchanged between the OS 213 and the keyboard data acquisition program 212.

Next, regarding the general operation of the automatic input / output program 215,
This will be described with reference to FIGS. 3 and 4. First, when the automatic input / output program 215 is executed, the automatic input / output program 215 will set itself to the OS 213 and the keyboard data acquisition program 2.
Position it between 12 and and secure your own work area for reading the registration data shown in Fig. 3. After such preparation, the automatic input / output program 215 reads the registration data. This registration data is prepared in advance in the external storage device 240 in the form as shown in FIG. 3, and the trigger data to be displayed on the display device 220 and when the trigger data is displayed. The table of the correspondence relationship with the automatic input data to be output to is constructed. In addition, the trigger data further includes data regarding the display position of the display device 220 and data regarding the display characters displayed at this display position.

After that, the automatic input / output program 215 operates whenever an application program 214 or PS 213 issues any request to the input device 230, and pseudo input / output to the application program 214, OS 213, or keyboard data acquisition program 212. The operation is performed.

Now, when the preparation of the host computer 100, the personal computer 200, and other communication lines is completed, a key request is generated from the host computer 100 via the application program 214. Upon receiving this key request, the automatic input / output program 215 confirms the presence / absence of data input from the input device 230 through the keyboard data acquisition program 212 as shown in step 2 of FIG. In this case, in step 3, the input device 230 is sent via the OS 213 and the display device interface program 211.
The input data is displayed on the display device 220. Subsequently, in step 4, the same data is passed to the host computer 100 via the OS 213 and the application program 214.
Next, the automatic input / output program 215 confirms in step 5 whether or not there is a reply from the host computer 100, and if there is a message, this message is sent to the OS 21.
3. Display on the display device 220 via the display device interface program 211. After displaying the message, the automatic input / output program 215 reads the display character or the data relating to the display screen from the display position of the trigger data previously read in the work area as shown in step 7. Specifically, via the OS 213 and the display device interface program 211, the relevant address of the text RAM 222 of the display device 220 is determined from the data relating to the display position of the trigger data, and stored in the text RAM 222 of this determined address. This is done by reading the contents. Continuing, in step 8, text RAM222
Compare the data read more and the data related to the display characters of the trigger data read in the work area in advance. If they match, in the next step 9, the automatic data corresponding to the trigger data read in the work area in advance will be displayed. The input data is displayed on the display device 220 via the OS 213 and the display device interface program 211, and in step 10, the automatic input data is transmitted to the host computer 100 via the OS 213 and the application program 214. After the transmission of this automatic input data, control is transferred to the host computer 100, and the automatic input / output program 215 waits for an input request from the host computer 100 side. The branch processing when the conditions are not satisfied in steps 2, 5, and 8 was not described in detail, but as is clear from FIG. 3, the intermediate step is skipped and the processing is skipped. It is something that can be advanced to.

Thus, in the embodiment, the host computer 10
When the message "ENTER LOGON" arrives from 0, input device 2
You can enter the "LOGON" command without operating 30. Further, in the embodiment, since the display screen of realization is read and the correspondence with the trigger data is confirmed, the data input by the input device 230 and displayed on the display device 220,
Data received from the host computer 100 and displayed on the display device 220 can be handled in the same manner. In other words, this allows the personal computer 200 to set a local password, for example. Specifically, a local password is used as the trigger data, and a true password (host computer
(Registered password in 100) is registered in advance as registration data of the automatic input / output program 215, and when a local password is input from the input device 230, this local password matches the previously registered local password. If so, the true password can be sent to the host computer 100.

According to such an embodiment, the host computer 100
According to the message, the reply command can be automatically transmitted, and the input operation of data or command can be reduced. Further, since the input data can be converted into another data and a reply can be made, the password and the like can be managed more carefully.

Although detailed description is omitted in the embodiment, in response to an input request from the application program 214 (host computer 100), the data input from the input device 230 is sent to the display device 220 via the OS 213 and the display device interface program 211. Those which are displayed immediately (obviously, the acquired data are also returned to the application program 214 via the OS 213), but the acquired data are not displayed on the display device 220 via the OS 213 but simply the application program 214.
What to pass to the OS, the acquired data OS213, application 214
There are those of various levels (types) such as those which are transferred to the host computer 100 via the, and the answerback data of the host computer 100 is displayed on the display device 220.

 The second embodiment of the present invention will be described below.

In the second embodiment, since the first embodiment described above cannot control even the transition of the automatic input (movement of the input state), this point is the fourth embodiment used in the first embodiment.
This is enhanced by replacing the processing in the figure with the processing shown in FIG. That is, a plurality of sets of registration data are prepared and the concept of step processing is added to this.
Specifically, at each step, set the limit to repeat the condition check with the trigger data for a fixed time or a certain number of times, and set the step destination to proceed if the condition is not satisfied within the check time. The term of the step at the time of failure is newly added.

Hereinafter, by the process shown in FIG. 5, the automatic response to the message from the host computer 100 and the input device 2
It is shown that automatic transmission of transmission contents according to input from the input device 230 such as transmission of a true password to the host computer 100 according to a local password received from 30 can be realized by step processing.

First, in order to facilitate understanding of the basic flow of the processing of FIG. 5 and the concept of step processing according to the second embodiment, the automatic transmission of a message from the host computer 100 as in the prior art described above is performed. The operation will be described by taking as an example the case where the processing of FIG.

The registration data shown in FIG. 6 prepares in advance the relationship of commands to be responded to in response to a message from the host computer 100 at each step in order to advance the TSS (Time Sharing System) processing using the host computer 100. Further, in the automatic input / output program 215, a work area for reading the registration data, a step counter for managing the step to be executed at present, a time-up counter for repeating the condition check, etc. are prepared.

Now, the operation of the automatic input / output program for performing the processing of FIG. 5 when using the registration data shown in the sixth step will be described. When you load the automatic input / output program,
The automatic input / output program, like the above-described embodiment, initializes itself and then stores the sixth data from the external storage device.
The registration data explained in the figure is read, and in step 1, the data of step 1 in FIG. 5 is set in the work area of itself. Then, the automatic input / output program sets the first step "1" to the step counter in the next step 2.
After setting, waits for input request from OS or application program. Since the operations from step 3 to step 7 thereafter are the same as those of the embodiment already described, the description thereof will be omitted. If the display data read in step 8 meets the condition of the trigger data, step 10, Processing similar to that of the embodiment already described in 11 is performed. Then, in step 12, the step counter is updated, and at the same time, the trigger data and the automatic input data to be checked next are read. In addition, as a result of the condition check in step 9, if the condition is not satisfied, the condition check count is exceeded or time is exceeded in step 13
Check with, and if not over, control is returned to step 3. If it is over, the number of steps registered in advance in the registration data when the specified condition is not satisfied and various data corresponding to this number of steps are calculated in step 14
Prepare for the step counter and work area. Next, if a new step is prepared in step 12 or step 14, it is checked in step 15 whether or not it is an end step, and if it is the end, the automatic input / output program 215 is ended. If not, the control is returned to step 3 and thereafter.

Next, the description will be continued in relation to each data shown in FIG. When the preparation on the host computer 100 side is completed, an input request reaches the automatic input / output program via the application program. At this stage, if there is no key input from the input device, the process proceeds to step 6, and if there is no message from the host computer 100, at step 8, display data is fetched from the display device 220. Here, in the next step 9, the captured data and the trigger data are compared with each other. However, as shown in FIG. 6, the trigger data is blank, so unconditionally, in this step "1" Input data “LOGON” is step 10
Is displayed on the display device 220 and the data is transmitted to the host computer 100 in step 11. Thereafter, the automatic input / output program 215 reads the trigger data of the next step "2" and updates the step counter to "2". Next, in step 15, it is judged whether or not the read data is the end step. However, at this stage, the control is restarted from step 3 in FIG. 5 because it is not the end step yet. By automatically inputting “LOGON”, the host computer 100 displays “MODE =” on the display device 220 and then makes a key input request. Therefore, step 3 and subsequent steps are executed, "MODE =" is read from the display device 220 in step 8, and is compared with "MODE =" of the trigger data in step 9. If the comparison of both data is established in step 9, the "TSS" command of the automatic input data is output in steps 10 and 11 below. If the message “MODE =” has not arrived from the host computer 100 side at this stage, this value is within the check time set in FIG. 6 after counting up the time-up counter in step 13. Is checked, and if it is within the check time, steps 3 and below are re-executed. That is, in step 13, it waits until the display data matches the trigger data within the check time. If the two data do not match within the check time, the number of steps in the unsuccessful step shown in FIG. 5 and the trigger data or automatic input data corresponding to the number of steps shown in FIG. It is read into the counter and other work areas.

As described above, in this embodiment, a plurality of trigger data and automatic input data corresponding thereto are prepared, and each item of the check time and the step at the time of failure is provided. If the required message is not obtained, the number of execution steps of the automatic input program 215 can be returned on the personal computer 200 side and the automatic input can be repeated again.

In the embodiment, when there is an input request from the host computer 100 or the application program 214 side, the input request is repeatedly generated continuously to the keyboard data acquisition program 212 until the necessary input from the OS 213 is completed, The number of occurrences is counted and used to manage the check time. That is, when the display data and the trigger data do not match in step 9, the time-up counter is counted up. Also,
Time-up counter is step 12 or step
It is initialized when the trigger data for the next process is read in 14.

Further, in the embodiment, it is of course possible to use an appropriate timer device for managing the check time.

Further, as shown in FIG. 7, registration data can be constructed. In this example, only steps “4” and “5” are different from those described above with reference to FIG. 6,
No automatic input data is set in this step. Therefore, in steps "4" and "5", the trigger data "467" is input from the input device 230 of the personal computer 200.
Unless the data matching 1 "and" KY "is input, the process with the host computer 100 does not proceed further. That is, if such a structure of the trigger data is adopted, the management of the password and the like is performed with the host computer 100. It can be separated and managed only by the personal computer 200 side.

The processing of FIG. 5 according to the second embodiment is applied to the processing of FIG. 5 as an example when only the automatic response to the message from the host computer 100 is applied as in the prior art described above. I explained the basic flow and the concept of step processing.

Hereinafter, the host computer 10 is processed by the processing of FIG.
Input device 230 such as automatic response to message from 0 and transmission of true password to host computer 100 according to local password accepted from input device 230
The operation of the second embodiment, in which the automatic transmission of the transmission contents according to the input from the step S1, is performed by the step processing will be described.

 The structure of registration data used in this case is shown in FIG.

A characteristic part of this example is that a local password on the personal computer 200 side is provided in steps "4" and "5". That is, the input device 230 is used in step "4" in which such a trigger data structure is adopted.
When the local password "A123" is entered, the control code "C" that cancels this local password "A123"
After outputting "AN", the password "4671" of the host computer 100 is continuously output automatically. In step "5", when the valid local identification code "XYZ" is input on the personal computer 200 side, this After outputting the control code "CAN" that cancels the local identification code "XYZ",
A valid identification code "KY" is automatically output on the host computer 100 side. Therefore, by preparing such trigger data and automatic input data, a local password can be set and managed on the side of each personal computer 200 separately from the host computer 100.

More specifically, the input device 230 and the display device 220 of the personal computer 200 handle all local passwords, and the host computer 100 side password is not displayed at all. This means that even if an outsider or the like knows the local password or the like, it cannot be used directly. Further, since the local password can be easily changed only by updating the registered data, if this is done regularly or irregularly, the security protection of the password and the like will be further strengthened.

In this embodiment, when the display data matches the trigger data in each step, the process proceeds to the next step. Therefore, the local password is configured in a hierarchical structure by preparing a plurality of local password comparison processes. It is also possible to manage it.

Note that step 9 of the process of FIG. 5 according to the second embodiment, that is, the part of the trigger data comparison process may be expanded. That is, as shown in the configuration example of the trigger data in FIG. 9, the number of items of the trigger data is set so that the position range in which the display data to be compared is fetched from the display device 220 can be specified and the display colors can be compared. To increase. Then, the trigger data of the start row (low), the end row (high) and the start column (low), the end column (high), and the display color for fetching the display data from the display device 220 are prepared,
As shown in FIG. 10, it is confirmed whether or not the display data captured from the display device 220 corresponds to the trigger data. To add a little explanation, step 1 in Figure 10
Then, whether the display character of the trigger data is within the line range specified by the trigger data, step 2
Then, whether the display character of the trigger data is within the column range specified by the trigger data, or step 3
Then, it is further examined whether the display character is the color specified in the trigger data, and if all the conditions are met,
For example, the processing from step 6 onward described with reference to FIG. 5 is continued, and the output operation of the automatic input data (details are omitted in FIG. 9) is performed. On the contrary, if the condition is not satisfied, the processing from step 13 onward described in FIG. 5 is advanced. Specifically, in the example of the trigger data shown in FIG.
When the white "ENTER" character is displayed for almost the entire screen of 0, output processing of unillustrated automatic input data is performed, and then from the 1st row and 1st column of the screen to the red "LOG"
When the character is displayed, the following automatic input data is being output. Of course, the same processing is performed when the above-mentioned local password or the like is used as the trigger data.

By doing so, not only the character data of the display device 220 but also the display color can be used for comparison with the trigger data.

Now, in the above embodiment, the host computer 10
In the relation between 0 and the personal computer 200, the application program of the personal computer 200 1
Although the description has been given of the case where the communication program is read as 4, the present invention is not limited to the personal computer.
It is also possible to use the application program 214 that is executed as a single unit of 200.

That is, FIG. 11 shows an example of an application program 214 for converting a file. In executing this program, after the program is started in step 1, the conversion mode is set in step 2 and then in step 3.
The source file name must be input in step 4, the conversion pattern data format in step 4, and the new file name in step 5. Therefore, in the embodiment, by preparing the registration data as shown in FIG. 12 in advance,
Each of these command data can be automatically input. That is, the automatic input / output program 215 is activated prior to the activation of the application program 214. Then, after reading the registration data, the automatic input / output program 215 unconditionally outputs "FCNV" in step "1" and starts the application program 214 ("FCNV" is the program name of the application program).
After this, the automatic input / output program 215 displays a message on the display device 220 from the application program 214 side, and whenever an input request arrives, it outputs the automatic input data corresponding to this message (matches the trigger data), Proceed with processing. According to this embodiment, the automatic input / output program 21
After activating 5, the subsequent processing can proceed without touching the input device 230.

Next, a configuration example of the trigger data shown in FIG. 13 will be described.
In this example, the local password is set in step "2" in addition to the one described above with reference to FIG. That is, in this embodiment, the subsequent processing cannot be performed unless the local password "KY" is input. As described above, in the embodiment, the application program 21 having no password registration function is used.
Also in 4, the local password can be set using the automatic input / output program 215.

[Effects of the Invention] As described above, according to the present invention, it is possible to easily obtain an automatic input device having a security protection function that can be corrected reliably and flexibly.
