Abstract

The invention discloses a method and a system for fixing electronic evidence and a user identity by a blockchain, belongs to the technical field of information security and aims to solve the problem that the user identity, the electronic evidence and a contract text can not be solidified and bound through the blockchain. The method comprises the following steps that: (1) through an electronic evidence snapshot file, binding the following texts including the identity authentication recording text of a user, an authorized behavior evidence text and the text of an electronic contract or protocol; (2) utilizing the blockchain to bind and solidify the electronic evidence snapshot file; and (3) storing a block transaction ID (Identity), the electronic evidence snapshot file, the identity authentication recording text, the authorized behavior evidence text and the text of the electronic contract or protocol. The system structurally comprises a user identity acquisition unit, a user identity authentication unit, an electronic contract or protocol display unit, an electronic evidence acquisition unit, an electronic evidence processing unit, an electronic snapshot generation unit and a storage unit.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and a system for fixing electronic evidence and user identity by using blockchain. Background technique [0002] With the advancement of the Internet, a large number of transactions involving clear responsibilities and identity identification appear on the Internet. The original method of using black and white characters and signatures cannot meet the existing needs. However, electronic contracts, electronic vouchers, and digital assets composed of data messages face many challenges, such as the content of data messages is easy to be tampered with, identity is difficult to determine, and time is difficult to fix. [0003] In the process of signing an electronic contract, how to solidify and identify the user's identity, how to solidify the electronic evidence generated in the transaction, and how to bind the user's identity, user behavior, time, place, contr...
