Embodiment Construction

[0016] As shown in FIG. 1 , it is a hardware architecture diagram of a preferred embodiment of the electronic document automatic signature system of the present invention. The system mainly includes an application computer 10 , a certificate server 20 , a network 30 , multiple client computers 40 and a database 50 . The application computer 10 is connected to the certificate server 20 and the client computer 40 through the network 30. The certificate server 20 is used to generate a key pair (comprising a public key and a private key) to authenticate the user's digital certificate application. If the user If the application is passed, a digital certificate is authorized to the user. The digital certificate includes: user information, public key, private key, validity period, etc., wherein the public key is disclosed to the other party, and is used for the other party to verify its identity. In this invention, the public key is also used to verify the electronic The identity of...

Abstract

The utility model relates to a system and a method for electronic document automatic signature; wherein, the method comprises the following steps: an electronic document used for electronic signature is generated and then the signature information is sent to a user end computer and the user is informed to carry out the operation of electronic signature; the operation of electronic signature is confirmed by the user; a digital certificate of the user is obtained from the database of a certificate server; the identity of the user is verified according to the digital certificate; after the verification of the identity of the user, a summary of the electronic document is generated; according to the private key of the digital certificate, the summary of the electronic document is encrypted, thus an electronic signature of the electronic document is obtained. With the utility model, the identity of the signer can be verified before the generation of the electronic signature, thus the electronic signature from forging is effectively prevented.

Description

technical field [0001] The invention relates to an electronic document automatic signature system and method. Background technique [0002] Usually, electronic documents are printed in paper and signed by hand. The implementation rate of e-commerce process is low, and the use of paper work increases the cost. In view of the fact that various countries have introduced corresponding electronic signature laws, electronic signatures have the same legal effect as traditional paper document signatures, and electronic signatures make electronic documents have privacy, integrity and non-repudiation, and can be used as evidence of the effectiveness of their rights application. [0003] Electronic signatures are mainly implemented by using digest algorithms and public key cryptography algorithms to encrypt and decrypt electronic documents. Digest algorithms (such as MD5, SHA-1, etc.), also known as one-way hash algorithms, are used to convert any variable-length The file is transfor...
