Problems solved by technology

[0007] The advantages and disadvantages of the closest existing technologies are: the current mainstream digital signature technology is based on public key cryptography RSA, DSA, elliptic curve and other signature systems
[0012] At the same time, the problem with this method is that it is the invisible digital signature data that really guarantees the security of the document, but the seal that the user sees is a digital image of a traditional seal or a handwritten signature, and it is easy for the user to follow the habit of using a traditional seal. Understand the electronic seal, which is prone to misuse and affects security
If the user does not make a distinction, it is easy to mistake it for a legal seal

Embodiment Construction

[0032] The electronic anti-counterfeit seal of the present invention is composed of a general seal signature and a digital signature, the digital signature is inserted into the seal signature as a part of the general seal signature, and the electronic anti-counterfeit seal combined by the digital signature and the seal signature is recorded as a part of the business document. In the electronic document recording the business: the preparation steps are as follows:

[0033] (1) When stamping an electronic document with an electronic anti-counterfeiting seal, the seal holder first digitally signs the electronic document by performing a hash operation on the document with sha1 or other hash algorithms to obtain a message summary, and then This message digest formulates a public key algorithm or digital signature, such as RSA, DSA or elliptic curve algorithm, and then performs digital image processing on the traditional seal signature, embeds the unique digital signature for this do...

Abstract

The present invention provides an electronic forgery prevention seal manufacture method. Electronic forgery prevention seal is composed of tradition seal signature and digital signature, wherein said digital signature using digital signature algorithm to calculate to signed electronic text and signer identity representative encryption key to obtain a string of digit, then embedding this digit to tradition seal image, it being used as a part of commerce file recording in said commercial electronic documents. Said invented method generated electronic seal not only can identify electronic documentation trueness, but also paper characteristic documentation trueness generated from electronic documents.

Description

1. Technical field [0001] The invention relates to a computer application technology or an e-commerce application technology, in particular to a method for making and using an electronic anti-counterfeit seal. 2. Background technology [0002] Today, with the rapid development of information technology, networks and computers make information dissemination and exchange more convenient and faster. In order to improve office efficiency, more and more government agencies and companies adopt electronic office software platforms (such as MS Office, WPS or other OA systems) to realize the transmission of official documents through the network and enjoy the speed and efficiency brought by the Internet. However, the ensuing network intrusions and attacks have brought great security problems, and its destructive power is far beyond people's imagination, and network security issues have attracted more and more attention. [0003] There are considerable differences between electronic ...
