Identity information safety authorization system and method based on block chain

Abstract

The invention belongs to the technical field of information safety technologies, and discloses an identity information safety authorization system and method based on a blockchain. The system comprises an identity information authorization terminal hardware module which is used for recognizing an identity IC card of a user, and is connected with an identity information chain through a service contract main module to carry out the verification of the identity information of the user; the encryption module is also used for encrypting identity information, generating a secret key for each user passing identity information verification and completing encryption and decryption operations on authorized contracts created by both parties of the contracts; the service contract main module is used for a contract B to carry out identity information authorization contract, identity information registration contract creation and contract sending, receiving and verification; Meanwhile, the contractparty A decides whether to accept the received authorization information. The identity information authorization record evidence is formed through the block chain technology, and it is guaranteed thatidentity information authorization cannot be falsely used, tampered and repudiated, and traceable verification is achieved.
