Abstract

The invention discloses an identity information management method and system based on block chain technology. The method comprises the following steps: identifying user identity through a block chainnetwork so as to protect personal privacy information; and performing identity verification on a user according to the identified user identity through the block chain network and the user module. Theidentity information management method disclosed by the invention has the advantages that unified identity management infrastructure with strong privacy protection, strong security protection and strong audit accountability is constructed based on the block chain network, and the unified identity management infrastructure can provide identity identification, identity verification, authorization,audit accountability and like services.

Description

technical field [0001] The present invention relates to the field of access control technology and blockchain technology, in particular to an identity information management method and system based on blockchain technology. Background technique [0002] The primary role of access control is to control how users and systems communicate and interact with other systems and resources. Access control is the first line of defense in information security management and the foundation of other security mechanisms. At the heart of access control is identity management. Referring to the "AAA" design requirements (Authentication, Authorization, Accounting), identity management mainly involves four key steps: identity identification, identity verification, authorization, and audit accountability. Among them, the main identification technologies are: static password authentication, token authentication (U-shield, SMS verification code, etc.), Challenge / Respond authentication, biometric...
