Fingerprint digital certificate-based electronic contract signing method

Abstract

The invention relates to a fingerprint digital certificate-based electronic contract signing method, which comprises the following steps that: each party of a contract is registered in a certificate authority (CA), and takes a fingerprint characteristic as a password; the CA generates a pair of public and private keys, and generates a digital certificate by using the public key and an account; the CA confirms the identity of each party of the contract, and issues the private key and the digital certificate; each party of the contract passes fingerprint verification at a user terminal, calls the private key to digitally sign the electronic contract, and transmits the electronic contract to the CA; the CA decrypts the signed electronic contract by using the public key, and confirms the legal identity of each party of the contract; the CA implants the electronic signature of each party of the contract into the electronic contract, and transmits the electronic contract to the user terminal of each party of the contract; and each party of the contract acquires the electronic contract into which the electronic signature of each party of the contract after passing the fingerprint verification at the user terminal. The CA and a user terminal system are adopted, and digital signature and fingerprint recognition technologies are combined, so that the security and confidentiality of the contents of the electronic contract and the signing process of the electronic contract are improved.

Description

technical field [0001] The invention relates to the field of electronic commerce, in particular to an electronic contract signing method based on a fingerprint digital certificate. Background technique [0002] With the popularization of the Internet and the development of e-commerce technology, electronic contracts, as the basis and core of e-commerce, are increasingly used in online business activities. [0003] At present, the commonly used method of signing electronic contracts is that the parties to the contract first determine the final electronic contract content document through electronic data exchange or email reply, then print out the paper contract and sign it, and finally scan it into an electronic document Or send it to the other party by fax. This method is relatively cumbersome to operate. Since the electronic contract is not encrypted during its confirmation and transmission, the electronic contract is easily intercepted or modified illegally, posing a thre...

AI Technical Summary

Problems solved by technology

Although this method is relatively simple to operate, it also does not encrypt the electronic contract, and does not confirm the legal identity of the contract signer during the contract signing process. Contracts usually lack sufficient electronic document information or support of signing traces, which in turn affects the legal effect of electronic contracts

[0005] Therefore, the existing electronic contract signing method needs to be improved
