Abstract

PROBLEM TO BE SOLVED: To improve the reliability of acknowledgment processing of an electronic slip using a computer system. SOLUTION: When an acknowledgment request is transmitted from a client computer of an acknowledging person, it is discriminated in a server computer whether this ID code and password are registered in a user authentication file 37c or not; and if it is discriminated that they are registered there, an authority register file 37b is retrieved to discriminate whether the acknowledging person corresponding to this ID code has authority of acknowledgment or not. If it is discriminated that he has this authority, the result is informed to the client computer as a requesting source to allow acknowledgment operation, and the server computer receives acknowledgment/non-acknowledgment information and writes an acknowledgment or non-acknowledgment mark on an electronic slip file based on this information.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a computer
The present invention relates to a system that enables electronic slip approval processing on the system.

[0002]

2. Description of the Related Art In general, various documents are exchanged between departments or between individuals in an office or a company.
Some of them, such as order slips, purchase settlement slips, and withdrawal slips, require the approval of a superior or a related department. Conventionally, paper such as carbon paper has been used for this type of slip, and rules have been established so that necessary approval can be obtained by transferring the paper to a supervisor or an approver of a related department. The number of approvers for one slip is generally two.

On the other hand, in recent years, offices, offices, and the like have a local area network (LAN) installed on the premises.
Are connected to personal computers of each in-house client, thereby performing data communication between the personal computers. However, at present, the use of this type of system is generally limited to transmission and reception of e-mail, facsimile mail, and the like.

Therefore, recently, it has been considered that the above-mentioned slips are converted into electronic files, and the electronic slips are transmitted using the above-mentioned computer network system so as to be approved by an approver. However, in order to achieve this, there are issues that must be solved, such as how to confirm the approver on a computer network system and how to prevent falsification of electronic slips. A solution was desired.

[0005]

As described above, in the conventional computer network system, no specific countermeasures have been established for the approval processing of electronic slips, and effective countermeasures are eagerly desired. The present invention has been made by focusing on the above circumstances, and the purpose thereof is to:
An object of the present invention is to provide a computer system having an electronic slip approval function and a storage medium storing an electronic slip approval program, which can increase the credibility of approval processing for an electronic slip.

It is another object of the present invention to provide a computer system having an electronic slip approval function capable of preventing falsification of an electronic slip and improving the security of the system.

[0007]

According to the present invention, there is provided a computer system in which a plurality of computers are connected via a network. At least one of the plurality of computers includes an electronic slip. Means, a first determining means for determining access qualification, a second determining means for determining approval authority, and an approval processing means.

[0008] When an approval processing request for the electronic slip stored in the slip storage means is input,
The first determining means determines the access qualification of the client that has input the approval processing request to the computer system based on the access qualification information prepared in advance, and when it is determined that the client has the access qualification, The second determining means determines the approval authority of the requesting client based on the approval authority information prepared in advance. Then, when it is determined that the requesting client has an approval authority sufficient to approve the electronic slip to be approved, the approval processing means performs an approval process on the electronic slip in accordance with the approval operation of the client. Is executed.

Therefore, according to the present invention, when an approval processing request for an electronic slip is input, it is first determined whether or not the client making the approval processing request is registered as a system user. Is determined. Only when it is determined that the user is registered as a system user and has the approval authority, the approval processing for the electronic slip is permitted.

[0010] That is, the client who has requested the approval processing is determined by an independent two-stage determination processing as to whether or not the client is qualified as an approval processor. Therefore, the credibility of the approval processing for the electronic slip can be kept high.

Another aspect of the present invention is a computer system in which a server computer and a plurality of client computers are connected via a network, wherein the server computer receives an electronic slip received from the client computer. An access qualification determination unit and an application qualification determination unit are provided in addition to a slip storage unit to be stored, an approval authority determination unit, and an approval processing unit.

When an electronic slip approval request is received from the client computer, the access qualification determining means first determines whether or not the requesting client has access qualification. When it is determined that the client has the application qualification, the application qualification determining unit determines the application qualification of the client that has made the application request based on the application qualification information prepared in advance. And
As a result of this determination, when it is determined that the application requesting client has the application qualification, the electronic slip transmitted from the application requesting client computer is received and stored in the slip storage means. .

Thus, according to the present invention, when a client makes an application for approval of an electronic slip, the access qualification to the server computer is first determined, and then the presence or absence of the application qualification is determined. And you have access,
Only if the applicant has the application qualification, the application for approval of the electronic slip can be made. That is, even when an electronic slip approval application is made, it is determined whether or not the electronic slip is qualified as an applicant by an independent two-stage determination process. Therefore, it is possible to eliminate the problem that an electronic slip which does not originally require approval is sent from a client who does not have the approval application qualification, thereby improving the efficiency of the approval process. In addition, by identifying applicants who can apply for approval,
It does not unnecessarily increase network traffic, thereby maintaining proper system operation.

Further, in each of the above inventions, the slip storage means stores the electronic slip main body and the management information necessary for the application and approval processing of the electronic slip main body individually in association with each other, and It is also characterized in that requests other than reading from the electronic slip body are rejected.

[0015] By doing so, the electronic slip stored in the slip storage means can no longer perform any processing other than reading from any client. For this reason, there is no fear that the applied electronic slip is falsified by a third party, and the security of the electronic slip approval processing can be improved.

The server computer 2 sends the I
When the D code and the password are sent, the user authentication file 37c is searched in step 7d, and the ID
It is determined whether a code and a password are registered. If not registered, it is determined that there is no access qualification to the server computer 2, and the requesting client computer PCn is notified that access is not possible.

If registered, step 7
From e, the process proceeds to step 7f, in which the authority registration file 37b is searched to determine whether the approver corresponding to the ID code has the authorization authority. If the user does not have the approval authority, the requesting client computer PCn is notified of the approval failure. On the other hand, when it is determined that the user has the approval authority, the process proceeds from step 7g to step 7h, where the client computer PCn is notified of the approval authority. At the same time, the corresponding electronic slip is read from the slip storage file 37a, and the requesting client computer PC
n.

Upon receiving the permission of the approval authority, the approver checks the contents of the electronic slip displayed on the display unit 21, and if the contents are appropriate, inputs the approval. On the other hand, if the contents are not appropriate, a rejection is input.
This approval / denial information is sent to the client computer PC
n to the server computer 2. Upon receiving the approval / denial information, the server computer 2 writes an approval mark or a denial mark at a corresponding position in the electronic slip file based on the received approval / denial information in step 7j, and the writing is performed. The electronic slip file is stored in the storage file 37a.

Thus, the approval processing of the electronic slip is completed.
The result of the approval / denial is notified to the client computer PC1 of the applicant who has made the approval application, and is displayed on the display unit 21.

As described above, in this embodiment, when an approval request for an electronic slip is transmitted from the client computer PC1 of the applicant, the server computer 2
First, it is determined whether or not the ID code and the password of the applicant are registered in the user authentication file 37c.
The authority registration file 37b is searched based on the D code to determine whether or not the applicant is qualified. If it is determined that the application is qualified, the request is sent to the requesting client computer PC1. In response, the electronic slip file sent from the client computer PC1 is received and the slip storage file 37a is received. To be stored.

When an approval request is sent from the client computer PCn of the approver, the server computer 2 first determines whether or not the approver's ID code and password are registered in the user authentication file 37c. If it is determined that the user is registered, the authority registration file 37b is searched to determine whether the approver corresponding to the ID code has the approval authority.
If it is determined that the user has the approval authority, the request is sent to the requesting client computer PCn to perform the approval operation, the approval / denial information is received, and the electronic slip is received based on the information. An approval mark or a rejection mark is written in the file.

Therefore, according to the present embodiment, the access qualification and the application qualification or approval authority are independent of each other when the applicant makes an application for approval of the electronic slip and when the approver performs the approval processing. Therefore, the approval application process and the approval process can be performed only when both of the two stages are passed.

Therefore, only the applicant who has the qualification for approval application can apply for approval of the electronic slip, thereby limiting the number of applications and enabling efficient approval processing. By identifying applicants who can apply for approval,
The traffic of the LAN 1 is not unnecessarily increased, thereby maintaining proper system operation. Further, since the person other than the person having the approval authority cannot perform the approval process or even refer to the electronic slip, the credibility of the approval of the electronic slip can be kept high.

The slip storage file 56a stores an electronic slip requested for approval from the client computers PC1 to PCn. Approval procedure registration file 56b
Stores the approval procedure information sent from the client computers PC1 to PCn attached to the electronic slip in association with the electronic slip.

On the other hand, the main control unit 50 includes, as functions relating to the approval of the electronic slip, access qualification determination means 31, application qualification determination means 32, application acceptance processing means 51, approval authority determination means 34, approval processing means 52 and a file access control unit 53.

The access qualification determining means 31 requests an ID code and a password from the requesting client computer when an approval application request or an approval processing request arrives from the client computer PC1 to PCn of the applicant or approver. Then, it is determined whether or not the incoming ID code and password are registered in the user authentication file 37c.

The application qualification judging means 32 searches the authority registration file 37b based on the ID code for the applicant who is judged to have the access qualification by the access qualification judging means 31, and judges whether the application qualification exists. And notifies the result to the client computer of the applicant.

When the application qualification judging means 52 determines that the application is eligible, the application reception processing means 51 first requests the applicant for approval procedure information. The information is stored in the approval procedure registration file 56b. Next, an electronic slip is requested from the applicant, and when the electronic slip is sent, the electronic slip is stored in the slip storage file 56a.

The approval authority judging means 34 searches the authority registration file 37b for the approver judged to have the access qualification by the access qualification judging means 31 based on the ID code and the type of the electronic slip to be approved. To determine whether the user has the approval authority, and notifies the result to the client computer of the approver.

The approval processing means 52 reads out the corresponding approval procedure information from the approval procedure registration file 56b when the approval authority determining means 34 determines that the approver has the approval authority, and also executes the slip storage file 56a.
The relevant electronic slip is read out from the server, and the approval procedure information and the electronic slip are transmitted to the client computer of the approver for display. When the approver sends information indicating approval / denial, the approval / denial information is described in the corresponding approval procedure information and then stored in the approval procedure registration file 56b.

The file access control means 53 sets a mode in which only reading is permitted and writing is prohibited with respect to the slip storage file 56a, whereby the electronic slip stored in the slip storage file 56a is overwritten, added, corrected, and deleted. All writing, such as deletion, is prohibited.

Next, the operation of the system configured as described above will be described. "Electronic Voucher Approval Application" FIG. 11 is a flowchart showing the procedure and contents of this electronic voucher approval application process. Note that, in the figure, the processing relating to the determination of the access qualification of the applicant and the determination of the application qualification are omitted because they are the same as those shown in FIG.

The applicant first creates an electronic slip to be applied on his / her client computer PC1. The creation of the electronic slip is performed by using the electronic slip creation processing means 11 provided in the client computer PC1 (step 11a).

When the creation of the electronic slip is completed, the applicant next inputs a connection request to the server computer 20. Then, a connection process to the server computer 20 is performed in the client computer PC1, and when the communication link is connected, the server computer 20 sends an ID code and password transmission request. On the other hand, when the applicant enters his or her own ID code and password, the ID code and password are transmitted from the client computer PC1 to the server computer.
Transferred to computer 20.

Upon receiving the ID code and the password from the applicant, the server computer 20 searches the user authentication file 37c to determine whether the ID code and the password are registered. If it is not registered, it is determined that there is no access qualification to the server computer 20, and the requesting client
The computer PC1 is notified that access is not possible.

On the other hand, if registered, the authority registration file 37b is searched to determine whether or not the applicant corresponding to the ID code has the application qualification. If there is no application qualification, the requesting client computer PC1 is notified that the application cannot be made. On the other hand, if it is determined that the user is eligible for the application, the client computer PC1 is notified of the application permission.

Now, as described above, the server computer 2
When application permission arrives from 0, the applicant sends an electronic slip application request from his / her client computer PC1 to the server computer 20 (step 11).
b). Then, the server computer 20 sends a request for an approval procedure to the requesting client computer PC1. Upon receiving this request, the applicant enters various information necessary for the approval procedure, for example, the applicant name, the slip name, and a plurality of approver names.

Then, the client computer PCn performs connection processing to the server computer 20 (step 12a), and when the communication link is connected, the server computer 20 sends an ID code and password transmission request. On the other hand, when the approver enters his or her own ID code and password, the ID code and password are transmitted to the client computer PC.
n to the server computer 20.

When the ID code and the password are sent from the applicant, the server computer 20 searches the user authentication file 37c to determine whether or not the ID code and the password are registered. If not registered, it is determined that there is no access qualification to the server computer 20, and the requesting client computer PCn is notified that access is not possible.

On the other hand, if it is registered, it is determined whether the approver corresponding to the ID code has the approval authority by searching the authority registration file 37b. If the user does not have the approval authority, the requesting client computer PCn is notified of the approval failure. On the other hand, when it is determined that the user has the approval authority, the client computer PCn is notified of the approval authority permission.

When the authorization of the approver is completed, the server computer 20 first proceeds to step 12b.
Reads out the corresponding approver procedure information from the approval procedure registration file 56b and sends it to the requesting client computer PCn. Upon receiving the approval procedure information, the client computer PCn displays the approval procedure information on the display unit 21.

Subsequently, when the approver performs an operation for requesting the transmission of the electronic slip, the client computer PC
n transmits an electronic slip transmission request (step 12).
c). Upon receiving the electronic slip transmission request, the server computer 20 reads the corresponding electronic slip from the slip storage file 56a and sends it to the requesting client computer PCn (step 12d). This electronic slip is displayed on the display unit 21 of the client computer PCn.

The approver checks the contents of the electronic slip displayed on the display unit 21 and, if the contents are appropriate, inputs the approval. On the other hand, if the content is not appropriate, a rejection is input (step 12e). These approvals /
The denial information is written in the corresponding approval result entry column in the approval procedure information. For example, the approver is approver 1 "Tanaka"
If so, the approval mark is written in the column of approval result 1 shown in FIG.

The approval procedure information in which the approval / denial information is written is transferred from the client computer PCn to the server computer 20, and replaces the corresponding approval procedure information previously stored in the approval procedure registration file 56b. It is memorized. Thus, the electronic slip approval process by the first approver ends.

When the approval process by the first approver is completed, the server computer 20 notifies the second approver that the electronic slip to be approved has been received. When the second approver receives this notification and performs an approval request operation, the client computer and the server
Approval processing is performed with the computer 20 by the same processing as in the case of the first approver described above.

As described above, in the second embodiment, in addition to the electronic voucher, approval procedure information that collects various information necessary for the approval processing of the electronic voucher is created, and these are stored in the voucher storage file 56a.
