Description

  The present invention relates to an improvement of an electronic seal stamp system that can obtain the same effect as a case where a user (creator or sender of an electronic document) attaches imprint image data to an electronic document to seal it on a paper document. It is.

  At present, most documents created on the job are electronic documents created using a computer, but there are cases where they are output on paper in order to obtain a seal from the supervisor. The stamping system that proves the intention of the stamper for approval / settlement has been established in Japan for many years, and it is maintained even today when the documents are digitized. As a result, there is a problem that the advantage as an electronic document is not fully exhibited, and the electronic document does not advance for an important document that needs to be stamped.

  Therefore, in recent years, an electronic seal system that enables electronic seal stamps on electronic documents on a network has been developed and used in many companies and government offices. This electronic seal stamp system does not simply paste the user's seal image data into an electronic document, but embeds security information such as an electronic signature or an electronic certificate obtained from a certificate authority into the seal image data so that a person other than the stamper can imprint it. When image data is copied and used illegally, the fact can be easily found.

  In addition, as shown in Patent Document 1, in the electronic seal stamp system provided by the applicant company, a seal data file in which seal image data of all users (all employees in the case of a company) are registered together with user names and passwords is stored. It is on a shared computer. Then, the user enters the user name and password from his / her terminal connected via the network, logs in to the electronic seal stamp system, retrieves his / her own imprint image data from the shared computer, and stamps it on the electronic document created on the terminal. ing.

  Furthermore, every time a user stamps the above electronic seal stamp, the stamp time and the serial number of the stamp counter are embedded in the seal image data, and the management system on the shared computer centrally manages these information, and which user is It records which electronic seal stamp was stamped and how many times it was stamped. Since these pieces of information cannot be changed, when a person other than the stamper copies the seal image data, there are a plurality of electronic seal stamps having the same stamp counter number, and unauthorized use is revealed.

As described above, the electronic seal stamp system is a system capable of stamping an electronic seal stamp on an electronic document while maintaining security. However, since the above electronic seal stamp system is a system for logging in to a seal stamp data file on a shared computer via a network, it cannot be connected to the network as in the case where an electronic document is created with a notebook computer at a business trip destination. Under the local environment, there is a problem that the electronic seal stamp cannot be called and used.
JP 2003-169051 A

  The present invention solves the above-mentioned conventional problems, and enables a user who is not connected to the network to use the electronic seal stamp in the same way as the connected state without losing the centralized management form of the electronic seal stamp. The purpose is to provide an electronic seal stamp system.

The electronic seal stamp system of the present invention made to solve the above-mentioned problem is to store the main seal data file in which the seal image data of each user is registered together with the user name, password and use history in the memory means of the shared computer, In the electronic seal stamp system for logging the seal image data taken out from the main seal data file by logging on to the shared computer management system from the terminal via the network, the management system sends the stamp to the user terminal. Checkout means for copying and lending a user's seal data file, block means for disabling access to the user's seal data file on a shared computer during lending, and returning a rented seal data file Usage history It possesses a check-in means for taking in the body seal data files shared computer, the user's terminal to the rented its users seal data file, means for recording the time and number of uses using the imprint image data in the terminal It is attached, and the use history of the seal image data being lent out at the time of return is added to the main body seal data file .

As time acquisition source system time on unique computer by using the time of imprint image data in lending to the user of the terminal refers to the system time of the shared computer except when unable to connect such to the other computer Preferably it is.

  The electronic seal stamp system according to the present invention, in a normal environment in which a user can log on to a shared computer management system from a terminal via a network, electronically imprint image data extracted from the main stamp data file of the shared computer as in the past. Documents can be stamped. Under this environment, the management system on the shared computer centrally manages information such as the stamping times of all electronic seal stamps and serial numbers of stamp counters.

  In addition, a user who wants to use his / her own electronic seal stamp at a business trip destination, etc., logs on to the shared computer in advance and uses the check-out means of the management system, and borrows the user's seal data file from the user's terminal. . Through this checkout procedure, the user can make an electronic seal stamp at his / her terminal. The seal data file lent to the user's terminal is attached with means for recording the use time and the number of times of use of the seal image data on the terminal. During this lending period, access to the seal data file of the user of the shared computer is disabled to prevent use by others.

  The user who returns from the business trip logs on to the shared computer from his terminal and uses the check-in means of the management system to return the rented seal data file. At that time, the electronic data stored in his terminal is stored. The use history of the seal is written in the main body seal data file of the shared computer. Therefore, the centralized management form of the electronic seal stamp by the shared computer management system is not impaired. In this way, according to the present invention, a user who is not connected to the network can use the electronic seal stamp in the same manner as in the connected state.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram of the entire electronic seal stamp system, and shows a state in which a shared computer 1 and terminals 2 of many users are connected via a network 3. A management system 4 for an electronic seal stamp system is set in the shared computer 1. The memory means 5 of the shared computer 1 stores a main body seal data file 6 controlled by the management system 4.

  In this main body seal data file 6, as shown in FIG. 2, seal image data 7, user name 8, password 9, usage history 10 and the like of each user are registered for all users. The usage history 10 includes a stamping time 11 for each stamp image data 7, a serial number 12 of a stamp counter, and other information. In addition, security information 13 such as an electronic certificate acquired from a certificate authority can be included.

  Under a normal environment, the user logs in to the management system 4 of the shared computer 1 through the network 3 by inputting a user name and password from his terminal 2, and his own imprint image data 7 from the main seal data file 6 And an electronic seal stamp can be stamped on the electronic document created on the terminal 2. As described above, the management system 4 centrally manages the stamping time and the number of times of stamping for all the stamp image data 7.

  The contents described above are the same as those of the conventional electronic seal stamp system. However, in the present invention, as shown in FIG. 1, the management system 4 of the shared computer 1 has a checkout means program 14, a block means program 15, and a check In-in program 16 is incorporated.

  The check-out program 14 has a check-out function for copying and lending the user's seal data file to the user's terminal 2. That is, as shown in FIG. 3, a user who wants to use his / her electronic seal stamp in an environment disconnected from the network 3 logs in to the management system 4 of the shared computer 1 via the network 3 in advance and enters the checkout program 14. The user is requested to lend the user seal data file. The checkout means program 14 copies and lends the seal data file requested from the main body seal data file 6 stored in the memory means 5 to the user terminal 2.

  This lending is merely a copy of the seal data file, but in order to make the situation similar to the case where the actual seal is lent, the block means program 15 works simultaneously with the lending by the check-out means, and the shared computer 1 during the lending period. Disable access to the user's seal data file. As a result, the electronic seal stamp lent out is not usable even by the person himself, as well as others, and unauthorized use is prevented. This state can be canceled by the following check-in.

  A user who has rented a seal data file can use his / her own electronic seal stamp to seal an electronic document even in a non-connected state with the network 3. For this reason, the electronic seal stamp system can be used even at a business trip destination. The user's terminal 2 loaned to the user's terminal 2 is attached with means for recording the use time and the number of times of use of the seal image data in the terminal 2. However, the use time is acquired from the system clock of the user's terminal 2 and recorded.

  A user who has returned from a business trip or the like logs in to the management system 4 of the shared computer 1 via the network 3 and performs check-in to return the seal data file lent using the check-in means program 16. At this time, the check-in means program 16 reads the usage history from the memory means of the user's terminal and takes it into the main body seal data file 6 of the shared computer 1.

  At the same time, the recording information used from the time when the check-out means is performed until the time when the check-in means is performed is written in synchronization with the data in the main body seal data file 6. As a result, the usage status of the electronic seal stamp during the lending period is also incorporated into the unified management by the management system 4 of the shared computer 1, and the unified management form is not impaired. At the same time as the check-in, the block means program 15 stops and returns to the normal management state.

  FIG. 4 is a block diagram showing a utilization state of hardware resources in the shared computer 1 used in the present invention. FIG. 5 is a flowchart showing the login process, FIG. 6 is a flowchart showing the check-out means, and FIG. 7 is a flowchart showing the check-in means.

  In the above description, each user has been described as having a single imprint image data 7. However, as shown in Patent Document 1, the same user can also use a plurality of types of imprint image data 7. In addition, since various security information embedded in the seal image data 7 is also lent out at the same time, the user who has lent out the terminal 2 can use an electronic seal stamp combined with an electronic signature or the like. In this way, according to the present invention, a user who is not connected to the network can use the electronic seal stamp in the same manner as in the connected state without damaging the centralized management form of the electronic seal stamp.

  In addition, according to the present invention, it is possible to use an electronic seal stamp such as an accounting department that is used frequently for one day by separating it from the system and loading the usage history for one day into the management system 4 of the shared computer 1. It becomes. In particular, when the number of users exceeds 1000, the response speed of the system may be reduced during a time period when access to the shared computer 1 from each user is concentrated. If the system is disconnected from the system and checked into the management system 4 of the shared computer 1 at night or the like, there is an effect that the burden on the system can be reduced.
