Embodiment Construction

[0027] The present invention provides a method for signing electronic contracts based on fingerprint digital certificates. In order to make the purpose, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] Usually there are two electronic contract signing parties, of course there may be more than one. The parties to the contract first jointly determine the final electronic contract content document through interactive means such as electronic data exchange or e-mail, so as to enter the final step of signing the contract.

[0029] figure 1 It is a flow chart of the method for signing an electronic contract according to an embodiment of the present invention. As shown in the figure, the method for signing an electronic contract based on a fingerprint digital certificate includes steps: .

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.
