Abstract

The invention provides a method for confirming a signer of an electronic contract with a digital signature combined with a handwritten signature. The method firstly performs real-name authentication and contract creation, and secondly, both parties sign the contract to sign the contract, and generate a contract signature feature and a digital signature, and then The supervision system verifies the contract signature features and digital signatures, and then performs special processing on the verified contracts, and finally puts the specially processed contracts on the blockchain for on-chain storage, and both parties to the contract can check the contract parameters by decrypting them. Contract, on the basis of confirming the identity of the contract signer through the traditional digital signature, the present invention increases the user's handwritten signature feature, enhances the identity authentication strength of the contract signer, increases the difficulty of contract forgery, and combines new blockchain technology as a contract. The storage platform ensures that the contract cannot be tampered with, forged and denied.

Description

technical field [0001] The invention relates to the technical field of electronic contracts, in particular to a method for confirming electronic contract signers by combining digital signatures with handwritten signatures. Background technique [0002] At present, domestic mainstream electronic contract solutions are mainly divided into two camps, namely traditional CA (Certificate Authority, e-commerce certification authority) institutions and Internet electronic contract platforms. The main ideas are as follows: [0003] (1) Real-name authentication [0004] Before 2015, traditional CA institutions generally conducted real-name authentication of customer identities offline, verifying user ID cards for individual users and business licenses for corporate users. [0005] After 2015, due to the popularity of P2P (peer-to-peer, peer-to-peer) Internet finance, online real-name methods are widely used, and ID card online verification (name, ID number matching query), live body...
