BLOCKCHAIN-BASED ACCESS CONTROL METHOD AND SYSTEM, MANAGEMENT TERMINAL AND ACCESS CONTROL TERMINAL

摘要

A blockchain-based access control method and system, a management terminal and an access control terminal. The method applied to the management terminal comprises: receiving an identity correspondence between externally inputted identity information of at least one legitimate user and an access control identification of at least one external access control terminal (101); generating an access control smart contract carrying the identity correspondence (102); determining a corresponding blockchain node in a blockchain system and storing the access control smart contract in the blockchain node (103); separately synchronizing the access control smart contract into blockchain nodes respectively corresponding to other management terminals in the blockchain system (104); and sending the access control smart contract to the at least one external access control terminal (105). Thus, the management difficulty of the access control terminal may be reduced.
