Design And Implementation Of Trusted Storage System Based On Blockchain

Biometric data applied to authentication and authentication often suffers from network threats and attacks such as illegal monitoring,deciphering,tampering and replay.It is a commonly used and effective method to store biometric information using a trusted third-party authentication server.However,the application background of Internet + Internet of Things is increasing the demand for distributed miniaturized microservices.How to store and protect biometric information on a non-central lightweight microserver is an urgent application problem.In this paper,with reference to the blockchain technology for non-central distributed processing,combined with the directory system of X.500 protocol,a lightweight blockchain data structure suitable for microservices is designed and constructed,and biometric authentication information processing records created through design are constructed.The table conveniently and securely manages the basic operations of storing,accessing,adding,updating,and the like of the biometric feature,and adding an index item to the processing record table,and combining the index table algorithm,improves the access speed and efficiency of the record in the block linked list.In the processing and storage process of biometric authentication information,this paper designs and implements a block coding algorithm to process irregular biometric authentication data,which is suitable for storage in blockchain list,realizes encryption algorithm to protect biometric authentication data block,and realizes authentication algorithm to confirm processing organism.The operator of the authentication data implements a hash algorithm to guarantee the integrity of the biometric data block.The consensus module,blockchain module,blockchain content module,blockchain verification module and query module designed and implemented in this paper ensure the credibility and security of the microservice system.This paper innovatively combines lightweight blockchain technology to design and implement bio-authentication information trusted storage technology for micro-servers.In the Raspberry-based embedded application platform,LayUI is used to implement front-end and micro-services as background and Redis for data caching.Consul implemented the back-end management system as a service registration.The research technology of this paper has certain application value for the distributed trusted storage of micro-service critical data of miniaturized platform.
