Electronic academic degree certificate data protection and sharing system based on block chains

Abstract

The invention relates to an electronic academic degree certificate data protection and sharing system based on block chains, and belongs to the technical field of block chains. According to the specific implementation scheme, the electronic academic degree certificate data protection and sharing system which is controllable by a user and coordinated by multiple departments is provided. The system is based on a Proof Of Authority (POA) consensus algorithm. Under the condition of following an existing academic degree management system, data consistency of all departments is achieved, and the data sharing efficiency is improved. Content encryption and multiple authentication are performed on the electronic academic degree certificate by using cryptographic technologies such as Hash encryption and digital signature, and high automation of academic degree awarding, auditing and verifying operations is realized by combining with an intelligent contract technology. By constructing a block chain alliance connecting an education management department, colleges, students and external users, comprehensive academic degree data sharing and academic degree certificate review are realized, and a brand new solution is provided for breaking through data intercommunication among the departments and improving privacy, security and credibility of academic degree certificates.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based electronic degree certificate data protection and sharing system. Background technique [0002] A certificate is a certificate issued by the government for related matters and is protected by law. In recent years, due to the shortcomings of traditional paper certificates, such as low shareability and poor transferability, electronic certificates have become a new trend. Electronic certificates, as professional and voucher-type electronic documents with legal and administrative effects, have increasingly become the main electronic certificates for market entities and citizen activities, and are important basic data to support the operation of government services. Conventional certificates are generally reviewed by the relevant management departments, and a certificate in a uniform format is issued as a certification certificate. The awarding and issuing ...

Problems solved by technology

[0003] In addition, all functional permissions of the traditional centralized system are concentrated at one point. After malicious intrusion, the stored information can be read, tampered with or deleted at will, and when the system suffers from a large number of DOS or DDOS attacks, it needs to consume a lot of resources to maintain The system is running normally, and data security issues should be highly valued
