Embodiment Construction

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] figure 1 It is a flowchart of an electronic document anti-counterfeiting method in an embodiment of the present invention. Such as figure 1 As shown, in this embodiment, the flow of the electronic document anti-counterfeiting method includes the following steps:

[0023] Step 101, dividing the entire contract seal pattern into several sub-seal patterns, the number of sub-seal patterns is equal to the number of pages of the electronic document of the contract;

[0024] Specifically, the seal pattern of the entire contract can be unevenly and randomly divided into several sub-seal patterns, and the number of sub-seal patterns is equal to the number of pages of the electronic document of the contract.

Abstract

The invention relates to a method and a device for electronic document anti-counterfeit. The method for electronic document anti-counterfeit comprises the steps that : a whole contract stamp pattern is segmented into a plurality of sub-stamp patterns, and the number of the sub-stamp patterns is equal to the page number of the electronic document of a contract; the sub-stamp pattern is stamped additionally at the border of each page of the electronic document of the contract; after all the borders of all the printed pages of the contract document are arranged in a certain mode, the complete contract stamp pattern is formed through combining all the sub-stamp patterns which are on the contract document. With the method and the device for traditional anti-counterfeit in the invention, illegal stamp operation of a tradition contract is avoided; the influence of human factors is reduced and a contract process is made to be circulated more efficiently; contract manufacturing cost and energy are saved; the most important matter is that the method and the device effectively assist in preventing forgery of the electronic document contract and improving security of the electronic document contract.

Description

technical field [0001] The invention relates to the field of computers, in particular to an electronic document anti-counterfeiting method and device. Background technique [0002] Typically, contract documents are in paper form. This form of contract can only become effective after the contract seal is affixed on the paper document of the contract. With the popularization of computers, contract documents are increasingly used in the form of electronic documents. The electronic document contract saves the transmission time of the contract, improves the efficiency of making the contract, and brings great convenience to both parties of the contract. However, there is a serious problem that cannot be ignored in the electronic document contract, that is, the contract in the form of electronic document cannot be directly affixed with the contract seal like the contract in paper form to prove the validity of the contract. Therefore, how to solve the anti-counterfeiting problem ...
