JPH06119363A - Electronic document authorizing system - Google Patents

Abstract

PURPOSE:To protect the unfair authorization and the content of a document in an electronic document system using a computer. CONSTITUTION:After the preparation of an electronic document, an authorizer adds authorization information such as the number of pages outputting authorized image data of the number, seal, sign, etc., of an authorizer and the authorized information of locations/sizes, etc., by an authorized information unabling means 4 and makes a writing protection attribute addition means 3 add the changed information of document data. When an operator performs the output request of a document, document data to which the authorized information is added is read from a document data storage means 1, a synthetic output means 5 reads authorized image data from an authorized image data storage means 2 based on this authorized information, synthesizes the data on document data and outputs it to an output device.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic document approval system, and more particularly to an electronic document approval system for protecting a document handled by a word processor or electronic mail.

[0002]

2. Description of the Related Art Conventionally, in this type of electronic document approval method, the name of the approver is inserted as character data when the document data is created.

[0003]

In the above-mentioned conventional electronic document approval method, since the name is entered as character data when the document data is created, there is no confirmation that the approver has really approved it, and the approval is made. It is said that electronic documents are exposed to threats of malicious acts such as criminal acts and fraudulent acts because the contents of documents can be changed after approval because approval by unauthorized persons and modification of document contents are possible at any time. There's a problem.

[0004]

The electronic document approval system of the present invention is a document data storage system for storing created electronic document data in the electronic document approval system of a computer system that handles documents of word processors and electronic mails. Means and
The approval image means for storing the stamp or signature of the approver as image data corresponding to the approver number and the data change of the electronic document data stored in the document data storage means are prohibited. Write protection attribute adding means for adding a write protection attribute to the electronic document data, and approval information including an approver number in the electronic document data stored in the document data storage means by the operation of the approver. And the approval information adding means for adding the write protection attribute via the write protection attribute adding means and the approval information adding means stored in the document data storage means added the approval information and the write protection attribute. Electronic document data obtained by reading out electronic document data by designating an approver number and reading out image data corresponding to the approver number stored in the approval image data storage means. It constituted by having a composite output means for outputting synthesized and the output device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment shown in FIG. 1 has a document data storage means 1 for storing document data of a word processor or electronic mail, and a stamp or signature of an approver as image data, and corresponds to the approver number. The approval image data storage means 2 for storing the data, the write protection attribute adding means 3 for adding the write protection attribute for prohibiting the modification of the document data stored in the document data storage means 1, and the document by the operation of the approver. Approval information addition means 4 for adding approval information such as an approver number, number of pages, position and size to the data and requesting the write protection attribute means 3 to make the document data unchangeable, and document data storage means. The approval image data stored in the approval image data storage unit 2 is extracted corresponding to the approval number of the approval information added by the approval information adding unit 4 in the document data stored in 1 and the document Over data and approval Ime - a Jideta synthesized to have a composite output means 5 for outputting to the output device.

To explain the operation of the embodiment shown in FIG. 1, the approver checks the content of the document when the document is completed, and the approval information adding means 4 is used to perform the approval process. The approval information adding means 4 adds approval information such as an approver number, the number of pages for outputting approval image data of a seal or a signature, and the approval information such as position and size to the document data stored in the document data storage means 1 and writes it. Protection attribute adding means 3
Request that the document data cannot be changed. The write protection attribute adding means 3 gives a write protection attribute to the document data so that the document data cannot be changed thereafter.

On the other hand, when the document data stored in the document data storage means 1 is output at any time in response to an output request from the operator, the synthesizing output means 5 causes the approval information adding means 4 to operate.
The approval image data corresponding to the approval number in the approval information added to the document data is extracted from the approval image data stored in the approval image data storage unit 2, and the approval image data in the approval information added to the document data is extracted. According to the number of pages, position and size to output the approval image data,
The document data and the approval image data are combined and output.

FIG. 2 is a diagram for explaining another embodiment of the present invention. In this embodiment, a document data storage means 11 for storing a document in which a user-defined character code is written in the approval column of a document handled by a word processor, and a user-defined character file in which the approver has registered his mark as a user-defined character. 12 and that only the approver knows the user-defined character code. Also, the word processor will give a password to the document,
Only a person who knows the password can change the document data.

In the above configuration, after the document creator creates the document, the approver checks the content of the document, and the input document 13 in which the user-defined character code corresponding to the approval mark is input in the approval column is the document data storage means. It is stored in 11. At this time, the password given only to the approver is given to the document. This password prevents approval by people other than the approver, and prevents unauthorized changes to the document after approval.When printing, the approver's approval mark and document data corresponding to the user-defined character code entered by the approver in the document data are printed. The output document 14 obtained by combining and is printed.

[0011]

As described above, according to the present invention, in the approval of the electronic document of the word processor or the electronic mail by the computer, the approval image data is included, and the composite image is output at the time of output, and the operation of the approver. By adding approval information to the document data, it is impossible to change the document data, so it is possible to prevent unauthorized approval by a person who is not qualified to approve, and prevent unauthorized modification after approval. , There is an effect that electronic documents can be protected from malicious and malicious acts such as crime and fraud.
