Description

  The present invention relates to a WEB content sharing system, a server device, an information processing terminal device, an operation restriction method, and a program in which a plurality of users share one WEB content and synchronize operations.

  In recent years, with the spread of Internet technology using the WWW (World Wide Web) system, various information can be acquired. In addition to the acquisition of information, various web services such as electronic commerce have been developed for the convenience of Internet technology. However, there are many scenes where the contents and operation methods of WEB contents are complicated and difficult to use. For this reason, a WEB browser is used to support a user of the WEB service, so that a plurality of users share one WEB content (hereinafter, such WEB content is referred to as “shared WEB content”). In addition, there is a “browser sharing method and system” that synchronizes each operation in the shared WEB content between terminals (see, for example, Patent Document 1).

  However, in the conventional WEB content sharing system such as Patent Document 1, since operations are synchronized regardless of the contents of the shared WEB content, for example, a store operator visits an EC (Electronic Commerce) site or the like. When the system is used to explain an operation to a customer (user), there is a problem that a store operator can perform a decision operation such as a sales contract that is originally permitted only to the customer. Therefore, it is necessary to perform operation restriction on the shared WEB content.

As a prior art example related to web content operation restriction, in a system in which a user and an operator share a WEB form, the operator prohibits the input operation for each input part by performing the restriction setting of the operation performed by the operator. In addition, there is an “input proxy system” that can be permitted and can be operated on the user side (see, for example, Patent Document 2).

  According to the present invention, it is possible to restrict operations according to shared WEB content and users, and it is possible to perform operation limitations common to all users.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

  A feature of the present invention is a mechanism for restricting one operation (operation) in a WEB content sharing system that jointly browses WEB content on a WEB browser between different terminals and synchronizes operation and display.

First, a comparison between the prior art and the present invention will be described with reference to FIG.
In the conventional WEB content sharing system, a method is proposed in which the shared server 2 operating as a proxy is synchronized using a dynamic change detection script and a communication applet. The display contents of each browser are as follows: the WEB content relay unit 21 on the shared server 2 makes an HTTP request to the shared WEB server 3 on behalf of the WEB browser 1 and the WEB browser 4 with the same content. WEB content). The dynamic change detection units 13 and 43 on the WEB browsers 1 and 4 detect an event generated by a user's operation such as onclick, and the other party passes through the shared command transfer unit 23 of the shared server 2 through the shared command communication units 14 and 44. Synchronize operation with your device.

  In the WEB content sharing system of the present invention, operation restriction information 22 which is information for restricting synchronization control is stored in advance on the shared server 2, and the operation restriction is performed by the WEB content relay unit 21 of the shared server 2. The operation restriction information for restricting the operation performed on the information processing terminal device for the shared WEB content is embedded in the shared WEB content to be targeted. After the shared WEB content is displayed, when the dynamic change detection unit 13 of the WEB browser 1 detects an event due to an operation such as a button, the operation restriction control unit 15 is based on the operation restriction information embedded. It is determined whether or not the event is an operation restriction. If the event is an operation restriction target, the operation is restricted.

The configuration of the first embodiment of the present invention will be described in detail with reference to FIG.
The WEB content sharing system according to the present embodiment includes a WEB server 3 in which the shared WEB content is disclosed, a WEB content relay unit 21 that relays the shared WEB content to each browser, and a sharing command transfer for synchronizing operations such as events. Unit 23, shared server 2 having operation restriction information 22, and WEB browsers 1 and 4 on a terminal (information processing terminal device such as a personal computer) operated by a user of this system. . The terminal device having the shared server 2 and the browsers 1 and 4 executes the operation restriction method by program control.

  The operation restriction information 22 is information for restricting operations performed on the information processing terminal device with respect to a predetermined shared WEB content, and is held in advance in a predetermined storage unit (database or the like) of the shared server 2. In the present embodiment, by using this operation restriction information, it is possible to determine whether or not a predetermined shared WEB content is an operation restriction target, and it is possible to set two kinds of operation restrictions. One is operation restriction (overall operation restriction) in the entire predetermined WEB page (WEB content). The other is an operation restriction (partial operation restriction) for only a part (input field, input button, check box, etc.) to which an ID tag is added in a predetermined WEB page. Therefore, the operation restriction information 22 is information added to each WEB page that is subject to operation restriction, and “total operation restriction information” indicating that the operation on the entire WEB page is restricted, and the operation restriction target. “ID tag information (partial operation restriction information)” indicating an ID tag added to a predetermined portion in order to restrict an operation at a predetermined portion in the WEB page. ,including.

  The operation restriction information 22 is added to a plurality of “operation restriction target URL information” indicating URLs of web contents (WEB pages) subject to operation restriction, and for each WEB page (URL) subject to operation restriction. “User operation restriction information” (for example, “operator = no operation / customer = operation is possible” or “can be operated” on a predetermined WEB page) or “information on operation restriction” for each user. Information indicating “operator = operable / customer = non-operable”).

  One “operation restriction target URL information” is associated with at least one of “total operation restriction information” and “ID tag information (partial operation restriction information)” and “user operation restriction information”. Stored / held.

  Each of the WEB browsers 1 and 4 is provided in the information processing terminal device and has dynamic change detection units 13 and 43 for detecting an event such as an input operation such as onclick in the WEB content display units 12 and 42, respectively. The web content control units 16 and 46 have shared command communication units 14 and 44 for communicating with the server 2 and operation restriction control units 15 and 45 for performing control based on the operation restriction information, respectively.

  The operation of this embodiment will be described with reference to FIGS. In this embodiment, it is assumed that WEB content is operated by the WEB browser 1.

  The WEB browser 1 and the WEB browser 4 access the shared server 2 together with the URL of the shared WEB content, and start sharing (step S1). At this time, the WEB browser 1 and the WEB browser 4 notify the shared server 2 of user attribute information indicating whether each is an operator or a customer. The shared server 2 temporarily holds the received user attribute information in the WEB content relay unit 21.

  The shared server 2 acquires predetermined shared WEB content (shared WEB page) from the WEB server 3 (step S2), and transmits the shared WEB content to the WEB content display units 12 and 42 via the WEB content relay unit 21. Forward. Here, before transferring the shared WEB content acquired from the WEB server 3, the WEB content relay unit 21 stores the URL of the shared WEB content to be transferred acquired from the WEB server 3 and the shared server 2 in advance. By comparing each operation restriction target URL information of the operation restriction information 22 and determining whether or not they match, it is determined whether or not the shared WEB content to be transferred is an operation restriction target ( Step S3). Further, the WEB content relay unit 21 identifies the user (for example, operator or customer) of each of the WEB browsers 1 and 4 based on the user attribute information temporarily stored in step S2.

  As a result of the determination in step S3, if the transfer target URL matches the operation restriction target URL information (step S3 / YES), the WEB content relay unit 21 determines that the shared WEB content is an operation restriction target, The operation restriction information associated with the matched operation restriction target URL information is added to the shared web content to be transferred and transferred to the web browsers 1 and 4 (step S4). The operation restriction information to be added is at least one of the whole operation restriction information and the ID tag information (partial operation restriction information) and the user operation restriction information.

  In this embodiment, for adding user operation restriction information, for example, when the browser 1 is identified as the operator and the browser 4 is the customer based on the user attribute information, the shared WEB to be sent to the browser 1 is used. User identification result such as adding user operation restriction information “operator = no operation” to content and adding user operation restriction information “customer = operation available” to the shared WEB content to be sent to the browser 4 The user operation restriction information is added to each browser on the basis of the user information. For example, the user restriction information “operator = operation impossible / customer = operation available” is used as common information for each browser 1, 4. You may make it add to the shared WEB content to send. In this case, the shared server 2 does not need to acquire user identification information and does not need to identify the user. The operation restriction control units 15 and 45 of the respective WEB browsers analyze the common user restriction information.

  As a result of the determination in step S3, when the transfer target URL does not match the operation restriction target URL information (step S3 / NO), the WEB content relay unit 21 determines that the shared WEB content is not the operation restriction target. Then, the shared web content is transferred to the web browsers 1 and 4. The WEB browsers 1 and 4 display the shared WEB content on the terminal by the WEB content display units 12 and 42 (step S10).

  The WEB browsers 1 and 4 receive the shared WEB content to which the operation restriction information is added, transferred from the WEB content relay unit 21, at the shared command communication units 14 and 44 of the WEB content control units 16 and 46. The shared web content is displayed on the terminal by the content display units 12 and 42 (step S5).

  When the user of the WEB browser 1 performs a predetermined operation on the browser after the shared WEB content is displayed on the terminal, the dynamic change detection unit 13 detects the operation as an event (step S6 / YES), Event information indicating the content of the detected event is notified to the shared command communication unit 14.

  The shared command communication unit 14 that has received the event information transmits the event information to the operation restriction control unit 15 and requests to determine whether or not the event of the event information is a restriction operation.

  Upon receiving the determination request and the event information from the shared command communication unit 14, the operation restriction control unit 15 recognizes the operation restriction information added to the shared WEB content, and the event of the event information is a restriction operation based on the operation restriction information. It is determined whether or not there is (step S7). For example, the browser 1 is identified as an operator, and a click operation is detected as an event in the shared WEB content being displayed on the browser 1, and the overall operation restriction information and “ When the user restriction information “operator = no operation” is added, all the operations of the operator in the displayed shared WEB content are all restricted, so the operation restriction control unit 15 is detected in the shared WEB content. It is determined that the click operation is a limited operation.

  As a result of the determination in step S7, if the event is not a limited operation (step S7 / NO), the operation restriction control unit 15 notifies the shared command communication unit 14 of the determination result, and the shared command communication unit 14 Event information indicating the contents of the event is transmitted to the two shared instruction transfer units 23. The shared command transfer unit 23 that has received the event information from the shared command communication unit 14 transfers the event information to the shared command communication unit 44 of the WEB browser 4. The operation restriction control unit 45 forcibly operates the event information (step S8).

  As a result of the determination in step S7, if the event is a restriction operation (step S7 / YES), the operation restriction control unit 15 displays a message on the display unit of the browser 1 that the performed operation is a restriction operation. At the same time, control for invalidating the operation is performed (step S9).

  Then, while sharing the same page, Steps S6 to S9 are repeated, and if a page transition occurs, the process returns to Step S3.

  In the present embodiment, as the operation restriction information added to each WEB content (WEB page), at least one of the whole operation restriction information and the ID tag information (partial operation restriction information) and the user operation restriction information are both included. Although added, at least one of the whole operation restriction information and ID tag information (partial operation restriction information) and the user operation restriction information are added, and any one of them added The operation restriction may be determined based on the information.

  In this embodiment, the operation restriction information is added to each WEB content (WEB page). However, the entire WEB content (all WEB pages) may be subject to operation restriction. In this case, for example, by adding the operation restriction information to the top page of a predetermined WEB content, the operation is performed so that pages belonging to the content are subject to operation restriction.

  As described above, according to the present embodiment, it is possible to operate only in the case of a specific user attribute depending on the content of the WEB content to be shared, and only a customer such as EC site contract determination is operated. It is possible to restrict the operation of WEB contents that should not be handled.

  In the description of the operation of the first embodiment described above, the operation is restricted as shown in steps S6 to S9 in FIG. 2, but it is also possible to perform an operation that allows the operation but does not notify the shared instruction transfer unit 23. It is. In this case, for example, it is possible to input a password or the like but not to notify the sharing partner of the input password.

  In the description of the operation of the first embodiment, the operation restriction information is stored in advance in the shared server. However, the operation restriction information is described in advance in the shared WEB content of the WEB server, not on the shared server. By doing so, the same operation can be performed. In this case, correction to the shared WEB content (description of operation restriction information) is required, but it is not necessary to determine whether or not the shared server is a restriction target, and the load on the shared server is reduced. This is also effective when the restriction cannot be determined by the URL (for example, when the display is changed by the parameter on the dynamic page and the URL does not change).

  As mentioned above, although each Example of this invention was described, it is not limited to description of the said Example, A various deformation | transformation is possible in the range which does not deviate from the summary.

  The present invention can be applied to a system that handles shared WEB content.

It is a block diagram which shows the whole structure which concerns on Example 1 of this invention. It is a flowchart which shows the operation | movement which concerns on Example 1 of this invention.
