Description

  The present invention relates to time signature processing in a client server system type document management system constructed on a network (LAN).

  2. Description of the Related Art Conventionally, in this type of document management system, a document management system having a device that can read a document, a server that manages document files, and a client such as a PC for using them is constructed.

  Furthermore, a document management system is constructed in such a manner that devices having a function of connecting to the server and transferring document files to the server are arranged on the same network.

  In recent years, the demand for managing electronic documents has increased, and an infrastructure for storing business transaction records as electronic documents is being developed.

  In addition, a time certification service (type stamp service) using a time signature is available from the Internet as means for proving that an electronic document exists at a certain time.

  Here, the time stamp service gives reliable time information to digital information in order to perform a time authentication service. This means that the existence of each document data is proved by using an organization that provides a technology (called a time stamp) that proves whether the digital information has been changed or altered.

Such a time certification service is provided in such a way that a fee is charged for each time signature.
JP 2004-126967 A

  As a client using such a time certification service, it is necessary to install a special application for using this infrastructure for each client as disclosed in Patent Document 1 above. Therefore, the cost for client management has become necessary.

  In addition, since the designation of the time stamp position is fixed, it is not possible to display a document file time-signed at a position intended by the user.

  In addition, when a document file is updated and a time signature is newly received, if the display position is fixed, only the latest time signature is displayed, and the certification history cannot be displayed at the same time. There was a problem.

  In other words, the conventional time signature process is performed to prove that the document file existed at the time of the time signature and that no modification has been made since that time. When the document is modified after the time stamp is added, the time signature must be performed again. For this reason, there is a problem in that it is impossible to specify such a display position even though it is necessary to specify a position to which a time stamp is added at the time of time signature.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to install software for requesting a time signature process from the first server apparatus in the data processing apparatus in the document management system.

And it is providing the mechanism which can confirm the arrangement | positioning of time signature information visually easily, or can change the arrangement | positioning freely.

  Further, the user can freely select the position where the time signature information certified by the first server device is pasted to the document file that receives the time signature information. And even if it receives a plurality of time signatures, it is to provide a mechanism that can recognize each time signature individually.

  The document management system of the present invention that achieves the above object has the following configuration.

  A first server device that provides a time signature processing service for a document file, and the first server device that mediates a time signature processing request from a data processing device to the first server device. And a second server device capable of issuing a time signature process.

  The time signature processing method of the present invention that achieves the above object has the following configuration.

  A first server device that provides a time signature processing service for a document file, and the first server device that mediates a time signature processing request from a data processing device to the first server device. A time signature processing method in a document management system having a second server device capable of issuing time signature processing, wherein the second server device receives time signature information issued by the first server device Time signature setting for displaying a selection part for selecting a visible display position to be pasted on a document file, and a preview part for synthesizing the time signature image and the document image of the document file at the visible display position in the selection part. Creation step for creating screen information, and transfer step for transferring the time signature setting screen information created in the creation step to the data processing device And the data processing device displays a time signature setting screen on a display device via a predetermined browser based on the time signature setting screen information acquired from the second server device, and the display A selection step of selecting a visible display position by the selection unit on the time signature setting screen displayed on the display device by the step, and based on the time signature screen information, the stored time signature image and the document file And a preview step of previewing a document image with a time signature, which is synthesized by associating the document image with the visible display position selected in the selection step, on a display device.

  This example is a system example illustrating a module configuration example of the client application 1010, the Web application 1050, and the server application 1040 in the document management system.

  In FIG. 2, it is assumed that the server application 1040 is running on the document management server 1, the web application 1050 is running on the web server 2, and the mail notification service 2010 is running on the mail sending server 3.

  Further, it is assumed that the client application 1010 is running on the client 4 and the client 5, and a general web browser application is running on the web client 6 and the web client 7.

  The system includes a client application 1010, a server application 1040, and a web application 1050.

  The client application 1010 and the server application 1040 are provided as application software that can operate on a computer operating system having general hardware resources. Here, the hardware resources correspond to a CPU, RAM, ROM, hard disk, and input / output device.

  The web application 1050 operates as a general web application that operates in cooperation with an HTTP (Hyper Text Transfer Protocol) server.

  Here, computers on which the client application 1010, the Web application 1050, and the server application 1040 operate are connected to the network via Ethernet (registered trademark) or the like.

  The computer is configured to be communicable using a predetermined protocol, for example, HTTP (Hyper Text Transfer Protocol).

  In the present embodiment, the client application 1010, the Web application 1050, and the server application 1040 are operated on different computers, but they may be operated on the same computer.

  In addition, this system is connected to the time certification server 1060 via a network, and functions such as time signature assignment and time signature verification provided by the time certification service 1061 can be used.

  The configuration of the client application 1010 will be described.

  In the client application 1010, reference numeral 1011 denotes a user interface control unit that controls an operation screen of a screen for an operator to operate.

  By operating the operation screen displayed by the user interface control unit 1011, the operator can browse, register, move, copy, delete, assign an electronic certificate, verify the document, etc. managed in this document management system. It has become.

  Similarly, time signatures can be assigned and verified, folders can be created, moved, copied, deleted, cabinets can be created and deleted, mail notification conditions can be managed, and mail notification settings can be set.

  Here, the operation of the operator is interpreted, and the main control unit 1012 performs actual work.

  The main control unit 1012 performs operations such as operation of the database 1042 and file conversion processing as necessary according to the operation of the operator.

  The cabinet management unit 1013 operates the database 1042 when an operation on the cabinet is performed, and performs processing such as cabinet creation and deletion.

  The folder management unit 1014 operates the database 1042 when an operation is performed on the folder, and performs processing such as creation, deletion, movement, and copying of the folder.

  The document management unit 1015 operates the database 1042 when an operation is performed on a document, and performs processing such as document registration, deletion, movement, and copying.

  The user group management unit 1016 operates the database 1042 when an operation is performed on a user or group, and performs processing such as registration or deletion of a user or group, attribute change, or registration or deletion of a user to a group.

  In addition, an access right setting process is performed in cooperation with the folder management unit 1014 and the document management unit 1015. Further, authentication processing for using the cabinet is also performed here.

  The keyword management unit 1017 manages classification keywords created by the user. Here, creation and deletion of classification keywords, setting of values for classification keywords, and the like are performed.

  The mail management unit 1018 performs a process of creating an operation notification mail and registering it in the mail transmission queue when the folder management unit 1014 or the document management unit 1015 performs an operation on a folder or a document.

  In the time stamp management unit 1019, corresponding processing is performed by using a function provided by the time certification server 1060 when a time signature is added or a time signature verification operation is performed in the document management unit 1015.

  The database access unit 1020 transmits database operation commands in the cabinet management unit 1013, the folder management unit 1014, the document management unit 1015, and the user group management unit 1016 to the server application 1040 through network communication. Similarly, the database access unit 1020 transmits database operation commands in the keyword management unit 1017, the mail management unit 1018, and the time stamp management unit 1019 to the server application 1040 through network communication. Then, the result received from the server application in response to the database operation command is returned to the requester that issued the database operation command.

  The file operation unit 1030 operates a file system provided by the operating system.

  Here, processing for registering a file managed by the file system of the operating system as a document in the document management system is performed.

  Also, a process of taking out a document registered in the document management system as a file to the file system of the operating system is performed.

  The web application 1050 receives an HTTP request from a web client. The Web application is a general Web application that performs processing such as transmitting a requested content such as an HTML page or an image file as an HTTP response to a Web client.

  Similarly, the web application 1050 is a general web application that performs processing for executing a program in response to a program execution request from the web client and transmitting the result as an HTTP response to the web client.

  The Web application is assumed to be constructed using CGI (Common Gateway Interface), JSP (Java (registered trademark) Server Pages), ASP (Active Server Pages), and the like.

  The Web application 1050 provides the same function as the client application 1010, but the user interface portion is different.

  That is, the configuration is almost the same as that of the client application 1010, but the HTML / HTTP processing unit 1051 that is an input / output portion with the operator is different.

  The HTML / HTTP processing unit 1051 executes a program in response to a program execution request from a Web client.

  Then, the HTML / HTTP processing unit 1051 configures the result as a screen using HTML or Java (registered trademark) Script, and transmits the result to the Web clients 6 and 7 as an HTTP response.

  Next, the configuration of the server application 1040 will be described.

  The database access unit 1041 operates the database 1042 in response to a request from the client application 1010 through network communication, and returns the result.

As described above, the Web clients 6 and 7 are configured to be able to display the time signature setting screen information acquired from the Web server 2 via a predetermined browser.

  Note that this screen is displayed via a predetermined browser when the user selects a document to which a time signature is to be added on the Web application 1050 on the Web clients 6 and 7 of the document management system and performs an operation for requesting the time signature setting. Displayed.

  In FIG. 3, reference numeral 301 denotes a user interface including a combo box for designating the display position of the visible display image of the time signature stamp attached together with the time signature.

  In the figure, “upper left” is selected, but it is also possible to select “upper right”, “lower left”, “lower right”, and the like.

  Reference numeral 302 denotes a button for requesting creation of a preview image. When this button 302 is pressed by a user operation, a preview image 303 is displayed on the display devices of the Web clients 6 and 7. In the preview image 303, a time stamp 404 is synthesized and displayed. Details of this processing will be described later with reference to FIG.

  Reference numeral 305 denotes a button for executing time signature assignment. When the user instructs to press the button 305 by a user operation, a request for time stamp assignment is issued to the Web server 2. When the time signature assigning process is completed, this screen is closed.

  Reference numeral 306 denotes a button for ending this screen without giving a time stamp.

  The Web clients 6 and 7 have a function of previewing a document file with time signature information shown in FIG. 3 via a predetermined browser.

  More specifically, the time signature image stored and managed by the Web server 2, the document image of the document file, and the visual display position selected by the user interface 301 are combined and combined. Then, the time signature screen information of the document image with the time signature created by the Web server 2 is acquired and used as a display device via a predetermined browser.

  Note that the preview processing is actually performed before the time certification service is executed for the time certification server 11 by a request from the Web server 2, so that the users of the Web clients 6 and 7 can check the pasting status of the time signature information. Visual confirmation is possible.

  FIG. 4 is a diagram for explaining an example of a database management table provided in the document management server 1 shown in FIG.

  Note that the cabinet management unit 1013, folder management unit 1014, document management unit 1015, and user group management unit 1016 of the Web server 2 shown in FIG. 1 are configured to be able to refer to the following management table via the database access unit 1020. Yes.

  For example, it includes at least a cabinet management table 401, a folder management information table 402, a document management table 403, a user management table 404, and a group management table 405. The configuration and function of each table will be described.

  The cabinet management table 401 includes a cabinet ID 401a and cabinet information 401b. The cabinet ID is identification information for identifying the cabinet.

  The cabinet information is actually composed of a cabinet name, cabinet creation time, and the like.

  The folder management table 402 is a table in which a plurality of folder records including a folder ID 402a, a parent folder ID 402b, folder attribute information 402c, an access right list 402d, a mail notification setting 402e, and the like are registered.

  One folder record is registered per folder. Folder records are created when an operator creates a folder and are deleted when the folder is deleted. The folder ID 402 a is a folder identifier having a unique value in the folder management table 402.

  The parent folder ID 402b stores the folder ID of the parent folder. By having the parent folder ID 402b, folders can be managed in a hierarchical structure on the tree.

  The folder attribute information stores information necessary for folder management such as a folder name, a folder creation time, an update time, a creator, an owner, and a storage expiration date. In the access right list, a list of a pair of access right for a user ID or group ID and a folder which will be described later is registered.

  The access right list 402d includes a “reference right” that allows only document names and document attributes to be referred to, and a “reading right” that allows browsing of document contents. The access right list 402d includes “write right” that allows document registration, document content change, folder creation, and attribute change, and “deletion” that allows document and folder deletion.

  The mail notification setting 402e holds “not notify mail” which does not transmit an operation notification mail even when a folder or document is operated in this folder.

  Also, the mail notification setting 402e holds “inherit the setting of the upper folder” that operates by taking over the mail notification setting set in the upper folder.

  Further, the mail notification setting 402e holds “Set to folder unique” for applying the mail notification setting to the folder. In addition, when “set for folder” is set, a list of mail notification conditions is stored.

  The document management table 403 is a table in which a plurality of document records including a document ID 403a, a parent folder ID 403b, document attribute information 403c, an access right list 403d, and the like are registered.

  One document record is registered per document. The document record is created when the operator registers a document, and is deleted when the document is deleted. The document ID is an identifier of a document having a unique value in the document management table 403.

  It is assumed that the document management table 403 stores preview image data of a file to which a time signature is attached.

  The parent folder ID 403b stores the folder ID of the folder in which the document is stored.

  The document attribute information 403c stores information necessary for document management by the document body, document name, document creation time, update time, document last access time, creator, and owner.

  The document attribute information 403c stores information necessary for document management such as classification information, preview images, and document types.

  The access right list 403d is the same as that of the folder information table 402.

  The user management table 404 is a table in which a plurality of user records including a user ID 404a and user information are registered.

  One user record is registered per user. The user record is created when the operator creates a user, and is deleted when the user is deleted. The user ID is a user identifier having a unique value in the user management table 404.

  The user attribute information 404b stores information necessary for user management such as a user name, password, user creation time, update time, mail address ID, and approver user ID.

  In the privilege information 404c, a user group creation privilege for managing users and groups and a keyword creation right for creating keyword information can be set on the database 1041.

  In the privilege information 404c, a time signature management privilege capable of managing time signature information, a time signature provision privilege capable of providing a time signature, and the like can be set.

  The group management table 405 is a table in which a plurality of group records including a group ID 405a, group information 405b, privilege information 405c, a user list 405d, and the like are registered.

  One group record is registered per group. The group record is created when the operator creates a group, and is deleted when the group is deleted.

  The group ID 405a is a group identifier having a unique value in the group management table 405.

  The group information stores information necessary for group management, such as group name, group creation time, and update time. As the privilege information, the same information as that used in the user management table 404 is used.

  The user list stores a list of user IDs of users registered in this group.

  FIG. 5 is a flowchart showing a first data processing procedure in the document management system according to the present invention. This processing corresponds to the processing procedure for creating the time signature assignment screen described with reference to FIG. In addition, (501)-(506) shows each step. Each step is realized by the CPU of the Web server 2 being executed by the Web server 2.

  Further, this processing is performed when the user selects a document file to which a time signature is to be added on the Web client application of the document management system from the Web clients 6 and 7 and performs an operation for requesting setting of the time signature. 2 is executed.

  This process is executed by the Web server 2 when the preview button 302 shown in FIG. 3 is pressed.

  First, in step 501, when the Web server 2 receives a time signature assignment screen creation processing request from the Web clients 6 and 7 shown in FIG. 1, is the processing due to the operation of the preview button 302 shown in FIG. Make a judgment.

  If it is determined that the preview button 302 is operated, the process proceeds to step 502. If the preview button 302 is not operated, the process proceeds to step 506.

  In step 502, the document management table 403 shown in FIG. 4 is inquired and a preview image of the document selected by the user is acquired.

  Next, in step 503, stamp image data corresponding to a visible image with a temporary time stamp is extracted. This stamp image data (data functioning as a time signature image) is assumed to be stored in advance by the Web client application.

  In step 504, the preview image data acquired in step 502 and the stamp image data corresponding to the visible image of the time stamp acquired in step 503 are combined by performing overlay development processing in a memory (not shown).

  At this time, the time stamp image data is pasted on the basis of the position information (a plurality of positions can be designated) designated by the operator at the time stamp pasting position 301 on the time signature assignment screen, and the composition processing is performed.

  The data format of the composite image is a format that can be directly displayed by a general Web browser, for example, a format that can be displayed by a general browser, such as JPEG or GIF. For example, any data format may be used.

  Also, time stamp image data enlargement / reduction processing and resolution conversion processing are performed according to the document size, the output paper size, and the like.

  The time stamp image data may be image data read by the user with a scanner or the like, or image data created by a drawing command such as an image processing application.

  Here, enlargement / reduction processing and resolution conversion processing are performed as needed. To reduce the load of such processing, time-stamp image data (virtual time signature images) corresponding to a plurality of sizes and resolutions are preliminarily stored. Prepare in a storage device on the Web server 2.

  Then, when obtaining the time stamp image data in step 503, it is possible to obtain the optimum time stamp image data according to the size and resolution of the preview image.

  Next, in step 505, a process of writing the image data synthesized in step 504 on a website accessible from the web clients 6 and 7 is performed. Here, it is assumed that the URL of the written image is stored.

  In step 506, the time signature assignment screen described with reference to FIG. 3 is created as an HTML page, transmitted to the Web clients 6 and 7, and the process ends.

  On the other hand, if the determination result in step 501 is based on the preview button operation, in step 506, an image element whose source is the URL to the preview image stored in step 505 is added. However, this image element is not included otherwise.

  As a result, the Web clients 6 and 7 can easily visually confirm the display position of the time-authenticated information before the time signature by the time certification server 11 with the Web server 2.

  Therefore, the prior confirmation process of the user's time signature information is reduced without adding a time signature to an arbitrary position of the document file managed by the user.

  Next, a process of receiving a time signature processing request from the Web clients 6 and 7 and performing a time signature on the time certification server 11 by the Web server 2 will be described with reference to FIG.

  FIG. 6 is a flowchart showing a second data processing procedure in the document management system according to the present invention. This processing corresponds to a processing procedure in which the Web server 2 performs time signature processing. In addition, (601)-(606) show each step.

  Further, in this process, the OK button 305 on the time signature adding screen shown in FIG. 3 which is transmitted to the Web clients 6 and 7 by the Web client 2 and the Web server 2 in Step 506 shown in FIG. Started when pressed.

  When the user operates the pointing device or the like (not shown) to press the OK button 305 on the time signature assignment screen shown in FIG. 3, a request for requesting the time signature assignment from the Web clients 6 and 7 to the Web server 2 is made. Will be sent via.

  At this time, parameters including the document ID of the document to be operated and the position where the visible image of the time signature is pasted are sent from the Web clients 6 and 7 to the Web server 2.

  First, in step 601, the Web server 2 makes an inquiry to the document management table 403 and acquires the document file entity to be operated from the document management server 1.

  In step 602, the time stamp display position information designated from the Web clients 6 and 7 is taken out and converted into an expression format used when the time signature is applied to the time certification server 11.

  Subsequently, in step 603, the time certification server 11 connected to the Internet 10 via the router 9 is requested to perform time signature assignment processing based on the information created in steps 601 and 602.

  Here, a time signature request is sent by a predetermined protocol from the Web server 2 to the time certification server 11 according to a predetermined procedure.

  In step 604, a time-signed file is received from the time certification server 11.

  Next, in step 605, processing for registering the document file with the name of the time book received from the time certification server 11 in step 604 as a document in the database 1042 managed by the document management server 1 is performed.

  At this time, whether to overwrite the original document, register it as a new version of the original document, or register it as a new separate document may be left to selection based on an instruction from the user. Moreover, you may make it register by the method defined beforehand among the said processes.

  In step 606, the Web server 2 creates a result screen as an HTML page, sends it to the Web clients 6 and 7, displays the time-signed document file, and ends this processing.
