Description

  Embodiments described herein relate generally to a browsing information management apparatus that manages information browsed by many users using a client terminal, and a program for causing a computer to function as the browsing information management apparatus.

  In a client / server model client terminal in which a plurality of client terminals are connected to a server via a network, it is possible to browse various information managed by the server using a browser. However, information that can be viewed includes information that can be shown to general users and information that only a specific user wants to show. Therefore, information that only a specific user wants to show is already encrypted by assigning a password to the unit of the record in which the information is recorded so that only a user who knows the password can view it. .

  However, the method of assigning a password in units of records cannot cope with a case where items that can be viewed by a general user and items that only a specific user wants to show to a specific user are mixed.

Hereinafter, an embodiment of a browsing information management device will be described with reference to the drawings.
Note that this embodiment is a case where a server of a client / server model realizes a function as a browsing information management apparatus.

  FIG. 1 is a system configuration diagram of a client / server model in the present embodiment. This system includes a plurality of client terminals 1, a browsing information management server 2 that functions as a browsing information management device, and a mail server 3. Each client terminal 1, browsing information management server 2, and mail server 3 are It is connected via a network 4 such as a LAN (Local Area Network) or the Internet.

  The browsing information management server 2 manages the user database 5 and the browsing information database 6. In the user database 5, information related to users who use each client terminal 1 is registered. In the browsing information database 6, browsing information that can be browsed by the user using the client terminal 1 is registered. In the present embodiment, in order to simplify the description, the screen 7 having the layout shown in FIG. 2, that is, the screen 7 including the subject, the first browsing item A, and the second browsing item B is browsed. As an example. It goes without saying that the browsing information is not limited to the screen information of the pattern shown in FIG.

  FIG. 3 is a schematic diagram showing the data structure of the user data record 5R registered in the user database 5. As shown in FIG. 3, the user data record 5R includes a user ID, a first attribute X, a second attribute Y, a user name, and a mail address as data fields.

  The user ID is set for each user in order to identify each user individually. The user name is the name of the user specified by the corresponding user ID, and the mail address is an e-mail address on the network 4 owned by the user. The e-mail stored in the mail server 3 can be downloaded to the client terminal 1 by this e-mail address.

  The first attribute X and the second attribute Y represent the affiliation of each user registered in the user database 5, and the second attribute Y is below the first attribute X. That is, all users are divided into a plurality of groups by the first attribute X, and each user belonging to one group is further divided into a plurality of groups by the second attribute Y.

  FIG. 4 is a schematic diagram showing a data structure of the browsing information record 6R registered in the browsing information database 6. As shown in FIG. As shown in FIG. 4, the browsing information record 6R includes a subject, a plurality of browsing items A and B, a browsing flag A and a restriction flag F for each browsing item A, a browsing target person code, and a browsing password as data fields.

  The subject is a name for individually identifying the browsing information record 6R registered in the browsing information database 6, and is controlled by the browsing information management server 2 so as not to overlap with the subject of the other record 6R. Multiple viewing items A. B is a component of the browsing information specified by the corresponding subject. The restriction flag F sets for each item whether or not the corresponding browsing items A and B are subject to browsing restriction. In the present embodiment, the restriction flag is “1” when the corresponding browsing item is a viewer restriction target, and the restriction flag is “0” when it is not a viewer restriction target.

  The browsing target person code is a code that limits the users who can browse the item when the browsing target restriction item exists in the browsing information of the browsing information specified by the corresponding subject. Specifically, the user ID or attribute X or Y is set in the browsing information record 6R as the browsing target person code. The browsing password is used to encrypt the item data subject to the viewer restriction. The browsing password is encrypted (obfuscated) with a specific encryption key and set in the browsing information record 6R.

  FIG. 5 is a block diagram showing a main configuration of the browsing information management server 2. As shown in FIG. 5, the browsing information management server 2 includes a CPU (Central Processing Unit) 21 as a control unit body, a ROM (Read Only Memory) 22 and a RAM (Random Access Memory) 23 as a main storage unit, An auxiliary storage device 24, a communication interface 25, and the like are provided. The auxiliary storage device 24 includes an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like. The communication interface 25 manages data communication with the client terminal 1 connected via the network 4. The CPU 21, ROM 22, RAM 23, auxiliary storage device 24, and communication interface 25 are connected by a bus line 26 such as an address bus or a data bus.

  In the browsing information management server 2 having such a configuration, the user database 5 and the browsing information database 6 are stored in the auxiliary storage device 24. The ROM 22 stores a browsing management program 31.

  On the other hand, a browser 32 for browsing browsing information is installed in each client terminal 1. That is, the client terminal 1 functions as a terminal that displays browsing information managed by the browsing information management server 2 using the browser 32. Here, the communication interface 25 constitutes a communication means with the terminal (client terminal 1).

  FIG. 6 is a flowchart showing the main procedure of the browsing information registration process executed by the CPU 21 of the browsing information management server 2 according to the browsing management program 31. An operator who registers new browsing information using the client terminal 1 activates the browser 32. Then, the operator selects the browsing information registration job from the job menu screen displayed on the display of the client terminal 1. Then, a browsing information registration request is issued from the client terminal 1 to the browsing information management server 2. When this registration request is received via the communication interface 25, the CPU 21 starts the browsing information registration process. First, the CPU 21 transmits the browsing information registration screen 8 through the network 4 to the client terminal 1 that has requested registration (ST1).

  An example of the browsing information registration screen 8 is shown in FIG. As shown in the figure, the browsing information registration screen 8 includes a subject input box 81, input boxes 82 and 83 for browsing items A and B, a viewer restriction button 84, a registration end button 85, and a cancel button 86. Is displayed. Therefore, the operator inputs the subject of browsing information in the input box 81. In addition, the operator inputs each data of the browsing items A and B in the input boxes 82 and 83. At this time, when the input item is a viewer restriction item, the operator inputs a viewer restriction button 84. When the input of the subject and each data of the browsing items A and B is completed, the operator inputs a registration end button 85. When the registration is stopped halfway, the operator inputs a cancel button 86. When any one of the viewer restriction button 84, the registration end button 85, or the cancel button 86 is input, the browser 32 displays the data in each of the input boxes 81, 82, and 83 together with the data for identifying the input button. 2 to send.

  The CPU 21 that has transmitted the browsing information registration screen 8 waits for any one of the cancel button 86, the viewer restriction button 84, and the registration end button 85 on the screen 8 to be input (ST2, 3, 4). ). When the input of cancel button 86 is detected from the data received via communication interface 25 (YES in ST2), CPU 21 ends the browsing information registration process.

  When the input of the viewer restriction button 84 is detected instead of the cancel button 86 (YES in ST3), the CPU 21 inputs data just before the viewer restriction button 84 is inputted in the client terminal 1. The browsing item A or B is specified as a viewer restriction item. Then, the CPU 21 stores the identification information of the viewer restriction item in the RAM 23 (ST5). Thereafter, the CPU 21 waits again for any one of the cancel button 86, the viewer restriction button 84, and the registration end button 85 to be input (ST2, 3, 4).

  When the input of registration end button 85 is detected, not cancel button 86 or viewer restriction button 84 (YES in ST4), CPU 21 has input into each of input boxes 81-83 of browsing information registration screen 8. A browsing information record 6R is created from the data of the subject and the browsing items A and B. At this time, if the subject entered in the input box 81 overlaps with the subject of another browse information record 6R registered in the browse information database 6, the CPU 21 attaches a series of numbers to the end of the subject. To make it unique. Further, the restriction flag F corresponding to the browsing items A and B is set to the initial value “0” (ST6: registration accepting means).

  Next, the CPU 21 checks whether or not there is a viewer restriction item (ST7). If the identification information of the viewer restriction item is stored in the RAM 23 in the process of step ST5, it is recognized that there is a viewer restriction item, and if it is not stored, it is recognized that there is no viewer restriction item.

  When there is no viewer restriction item (NO in ST7), the CPU 21 registers the browsing information record 6R created in the process of step ST6 in the browsing information database 6 (ST10). The CPU 21 ends the browsing information registration process.

  When there is a viewer restriction item (YES in ST7), the CPU 21 updates the restriction flag F corresponding to the viewer restriction item in the browsing information record 6R to “1” (ST8). Thereafter, the CPU 21 executes a viewer restriction process specifically shown in FIG. 7 (ST9). That is, the CPU 21 transmits the viewer setting screen 9 through the network 4 to the client terminal 1 that has requested registration (ST11).

  An example of the viewer setting screen 9 is shown in FIG. As shown in the figure, the viewer setting screen 9 includes a first attribute X selection box 91, a second attribute Y selection box 92, a user ID selection box 93, a setting end button 94, and a cancel button. A button 95 is displayed. In the selection box 91, a list of the first attributes X is displayed in a pull-down manner. In the selection box 92, a list of second attributes Y contained in the first attribute X selected in the selection box 91 is displayed in a pull-down manner. In the selection box 93, a list of user IDs and user names of all users is displayed in a pull-down manner.

  When a user who belongs to any one or more first attributes X is a viewer and other users are non-viewers, the operator selects all the first attributes X corresponding to the viewer from the list in the selection box 91. select. In addition, when a user who belongs to any one or more second attributes Y among the users belonging to the first attribute X is set as a viewer and other users are set as non-viewers, the operator selects All the second attributes Y corresponding to the viewer are selected from the list in the box 92. On the other hand, when any one or more users regardless of attributes are viewers and other users are non-viewers, the operator selects all user IDs corresponding to the viewers from the list in the selection box 93. To do.

  After selecting the viewer, the operator inputs a setting end button 94. Note that the operator inputs a cancel button 95 when the viewer setting is stopped halfway. When the setting end button 94 or the cancel button 95 is input, the browser 32 sends the data of the viewer selected in each selection box 91, 92, 93 to the browsing information management server 2 together with the data for identifying the input button. Send.

  The CPU 21 having transmitted the viewer setting screen 9 waits for the cancel button 95 or the setting end button 94 on the screen 9 to be input (ST12, 13). When the input of cancel button 95 is detected from the data received via communication interface 25 (YES in ST12), CPU 21 ends the browsing information registration process.

  When the input of the setting end button 94 is detected instead of the cancel button 95 (YES in ST13), the CPU 21 stores the browsing target person code in the RAM 23 based on the data selected in the selection boxes 91, 92, 93. (ST14: browser accepting means). Specifically, when the first attribute X is selected in the selection box 91 but the second attribute Y is not selected in the selection box 92, the first attribute selected in the selection box 91 is displayed. The attribute X is the browsing target person code. When the first attribute X is selected in the selection box 91 and the second attribute Y is selected in the selection box 92, the first attribute X selected in the selection box 91 and the selection box The second attribute Y selected at 92 is the browsing target person code. When the user ID is selected in the selection box 93, the selected user ID becomes the browsing target person code.

  When the browsing target person code is stored in the RAM 23, the CPU 21 transmits the browsing password setting screen 10 to the client terminal 1 that has requested registration (ST15).

  An example of the browsing password setting screen 10 is shown in FIG. As shown in the figure, the browsing password setting screen 10 displays a browsing password input box 101, a setting end button 102, and a cancel button 103. The operator inputs a desired end password in the input box 101 and then inputs a setting end button 102. In addition, the input of the browsing password is arbitrary and does not necessarily need to be input. When not inputting, the cancel button 103 is input.

  The CPU 21 that has transmitted the password setting screen 10 waits for the cancel button 103 or the setting end button 102 on the screen 10 to be input (ST16). When the input of cancel button 103 is detected from data received via communication interface 25 (NO in ST16), CPU 21 automatically generates a browsing password using a predetermined algorithm (ST17). Then, the CPU 21 stores the automatically generated browsing password in the RAM 23 (ST18).

  When the input of the setting end button 102 is detected instead of the cancel button 103 (YES in ST16), the CPU 21 acquires the data input in the input box 101 as a browsing password. Then, the CPU 21 stores this browsing password in the RAM 23 (ST18: password accepting means).

  Next, the CPU 21 uses the browsing password stored in the RAM 23 in the process of step ST18 as the data of the browsing restriction item in which the restriction flag F is set to “1” in the browsing information record 6R created in the process of step ST6. (ST19: data encryption means). Further, the CPU 21 encrypts this browsing password with a specific encryption key (ST20: password encryption means). Thereafter, the CPU 21 adds to the browsing information record 6R the browsing target person code stored in the RAM 23 in the process of step ST14 and the browsing password encrypted in the process of step ST20 (ST21).

  Next, the CPU 21 searches the user database 5 with the browsing target person code stored in the RAM 23, and acquires the mail address of the user set as the browsing target person (ST22). For example, when the browsing target person code is the first attribute X, all user data records 5R in which the first attribute X is set are detected, and the mail address of the record 5R is acquired. Similarly, when the browsing target person code includes the first attribute X and the second attribute Y, all the user data records 5R in which both the first attribute X and the second attribute Y are set are stored. It detects and acquires the mail address of the record 5R. When the browsing target person code is a user ID, the user data record 5R in which the user ID is set is detected, and the mail address of the record 5R is acquired.

  In this way, if the user's e-mail address set as the browsing target is acquired, the CPU 21 is an electronic device for notifying the browsing target of the browsing information subject and the browsing password before encryption with the encryption key. Create an email. Then, the CPU 21 transmits the created electronic mail to the mail server 3 through the network 4 (ST23: password notification means).

  Thereafter, the CPU 21 registers the browsing information record 6R to which the browsing target person code and the browsing password are added in the processing of step ST21 in the browsing information database 6 (ST10: browsing information registration means). The CPU 21 ends the browsing information registration process.

  The electronic mail transmitted to the mail server 3 is accumulated in the mail server 3. The operator of the client terminal 1 can read e-mails addressed to him stored in the mail server 3 using mail software. That is, the operator can know the subject and the browsing password of the browsing information set as the browsing target by reading the e-mail addressed to the operator. The email browsing password is not encrypted (obfuscated) with the encryption key.

  FIG. 8 is a flowchart showing the main procedure of the information browsing support process executed by the CPU 21 of the browsing information management server 2 according to the browsing management program 31. An operator who browses arbitrary browsing information using the client terminal 1 activates the browser 32. Then, the operator selects an information browsing job from a job menu screen displayed on the display of the client terminal 1. Then, an information browsing request is issued from the client terminal 1 to the browsing information management server 2. When the browsing request is received via the communication interface 25, the CPU 21 starts the information browsing support process.

  First, the CPU 21 transmits a browsing information list screen through the network 4 to the client terminal 1 that has requested browsing (ST31). On this list screen, the subject names of the respective browsing information records 6R registered in the browsing information database 6 are displayed as a list. Therefore, the operator selects a subject of browsing information desired to be browsed from the list. When the subject is selected, the browser 32 of the client terminal 1 transmits the subject to the browsing information management server 2.

  CPU21 which transmitted the browsing information list screen waits for reception of the subject selected in the client terminal 1 (ST32). If the subject is received (YES in ST32), the CPU 21 calls the browse information record 6R of the subject from the browse information database 6. Then, the CPU 21 transmits browsing information including the subject of the browsing information record 6R and the data of the first and second browsing items A and B to the client terminal 1 through the network 4 (ST33).

  Thereby, on the display of the client terminal 1, the screen 7 on which the subject of the browsing information and the first and second browsing items A and B are laid out is displayed. However, when the first and second browsing items A and B are encrypted by the browsing password, the encrypted data is displayed. Or nothing is displayed.

  The CPU 21 confirms whether or not there is a viewer restriction item in the related items A and B laid out on the screen 7 (ST34). If there is no viewer restriction item (NO in ST34), CPU 21 waits for a browsing end command from client terminal 1 (ST35). When the end of browsing is instructed, the CPU 21 returns to the process of step ST32. At this time, the screen of the client terminal 1 is switched to the browsing information list screen.

  When there is a viewer restriction item (YES in ST34), CPU 21 waits for a browsing end command from client terminal 1 (ST36) or selection of a viewer restriction item (ST37). When the viewer restriction item is selected (YES in ST37), CPU 21 transmits a user ID and password input screen to client terminal 1 (ST38).

  Thereby, the input screen of the user ID and the password is displayed on the display of the client terminal 1. Therefore, the operator inputs his / her user ID and browsing password. The operator can know the browsing password if there is an email notifying the browsing password of the subject selected by himself / herself in the email addressed to his / her email address. In other words, an operator who has not received the e-mail notifying the browsing password of the subject cannot know the browsing password.

  CPU21 which transmitted the input screen of user ID and a password waits for a user ID and a password being input in the client terminal 1 (ST39). When the user ID and password are input (YES in ST39), CPU 21 confirms whether or not the user specified by the input user ID is a browsing target person (ST40).

  For example, when the browsing target person code of the browsing information record is a user ID, the CPU 21 checks whether or not there is a browsing target person code that matches the input user ID. If there is a browsing target person code that matches the input user ID, the CPU 21 determines that the user of the client terminal 1 is the browsing target person. If the browsing target person code is the first and second attributes X and Y, the CPU 21 searches the user database 5 with the input user ID, and the user data record identified by the user ID. 5R first and second attributes X and Y are acquired. Then, the CPU 21 checks whether or not the acquired first and second attributes X and Y match the browsing target person code. If they match, the CPU 21 determines that the user of the client terminal 1 is the browsing target person. .

  When the user is a person to be browsed (YES in ST40), CPU 21 decrypts the browse password of the browse information record with a predetermined decryption key. Then, the CPU 21 confirms whether or not the decrypted browsing password matches the password input at the client terminal 1 (ST41: determination unit). If they match, the password entered is correct. In this case (YES in ST41), CPU 21 decrypts the data of the viewer restriction item in the browsing information record with the browsing password (ST42). Then, the CPU 21 transmits the decrypted data to the client terminal 1 and displays it in the corresponding browsing item column on the screen 7 (ST43: permission means). Thereafter, the CPU 21 returns to the process of step ST36.

  If the user is not a person to be browsed (NO in ST40), or if the password is incorrect (NO in ST41), CPU 21 counts up a retry counter (ST44). The CPU 21 accepts input of the user ID and password until the number of retries counted by the retry counter exceeds the upper limit value N (ST45). If the number of retries exceeds upper limit N (YES in ST45), CPU 21 outputs an error message to client terminal 1 and ends the current information browsing support process.

  If browsing termination is instructed from client terminal 1 in the process of step ST36 (YES in ST36), CPU 21 returns to the process of step ST32. At this time, the screen of the client terminal 1 is switched to the browsing information list screen.

  When the subject is not selected in the process of step ST32, the CPU 21 confirms whether or not browsing termination is instructed from the client terminal 1 (ST46). If browsing is not instructed (NO in ST46), it waits for the subject to be selected. When browsing is instructed (YES in ST46), CPU 21 ends this information browsing support process.

  In the present embodiment configured as described above, the user can register browsing information that other users can browse using the client terminal 1. And at the time of registration, a viewer can be restrict | limited about any one or both of the browsing item A or the browsing item B which comprises this browsing information. As a person to be browsed, a user ID can be used to specify one person at a time, or an attribute X or Y can be used to specify a group as a group.

  The data of items for which the viewer is restricted is encrypted with a predetermined browsing password. Therefore, even if a general user browses the browsing information using the client terminal 1, it cannot know the data of the items for which the viewer is restricted.

  On the other hand, the browsing password is notified to the browsing target person in advance using an e-mail. Therefore, the browsing target person can browse the data of the items for which the browsing person is restricted by inputting the browsing password when browsing the browsing information using the client terminal 1.

  As described above, according to the present embodiment, even in the case of browsing information in which items that may be shown to general users and items that only a specific user wants to show to a specific user are mixed in the browsing information item unit, It can be easily registered in the browsing information database 6 of the management server 2.

  In the present embodiment, the browsing password given to the browsing information registered in the browsing information database 6 is encrypted with a predetermined encryption key. Therefore, even if the browsing information registered in the browsing information database 6 is illegally accessed, the illegal executor cannot recognize the browsing password, and thus the browsing data cannot be browsed by the browsing user.

  Moreover, in this embodiment, when a user registers browsing information, a browsing password can be designated. Therefore, by deciding the browsing password between the user and the browsing target person, the browsing target person can retrieve the data of the items whose browsing is restricted without using the browsing password notification system by e-mail. It becomes possible to browse.

  From the opposite viewpoint, since there is a browsing password notification system by e-mail, the user does not have to consider the browsing password when registering browsing information. Therefore, the burden on the user can be reduced.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, e-mail is exemplified as a mechanism for notifying the browsing target person of the browsing password. However, the present invention is not limited to this, and any mechanism that can notify the browsing password with high security to the browsing target person. That's fine.

  Moreover, in the said embodiment, in the procedure of a viewer restriction process of FIG. 7, encryption of the data of a visitor restriction item and encryption of a browsing password are performed as step ST19,20,21, and after that, as step ST22,23 The e-mail of the browsing password is sent, but the e-mail of the browsing password may be sent first, and then the data of the browsing restriction items and the browsing password may be encrypted.

  Moreover, in the said embodiment, although user ID was input with the browsing password at the time of browsing a browsing restriction item, the timing which inputs user ID is not limited to this time. Normally, when the client terminal 1 is started up, the user logs in by entering his / her user ID. Therefore, by using the user ID input at the time of login when browsing the browsing restriction item, it may be omitted to input the user ID when inputting the browsing password. In addition, if the usage password has a high security for the browsing password, the user ID can be omitted.

  In the above embodiment, the browsing management program for realizing the functions of the invention is recorded in advance in the ROM 22 which is a program storage unit in the apparatus. However, the present invention is not limited to this, and a similar program may be downloaded from the network to the apparatus. Alternatively, a similar program recorded on the recording medium may be installed in the apparatus. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by the apparatus. Further, the function obtained by installing or downloading the program may be realized in cooperation with an OS (operating system) in the apparatus.

  In addition, although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
