Data security mechanism of hyperledger fabric and its application in academic documents verification system
Keywords:
blockchain, distributed ledger technology, data security, academic documents verification, hyperledger fabricAbstract
Blockchain technology ensures that data is tamper-proof, traceable, and trustworthy. This article introduces a well-known blockchain technology implementation—Hyperledger Fabric. The basic framework and privacy protection mechanisms of Hyperledger Fabric such as certificate authority, channel, Private Data Collection, etc. are described. As an example, a specific business scenario of an academic documents verification system m is figured out. And accordingly, some design details about how to apply these privacy protection mechanisms are described. The information of each enterprise in the blockchain needs to be shared, in this process, the privacy of ADVs needs to be protected, and we need an algorithm to protect privacy. Data sharing is not implemented in the traditional academic documents verification system. Therefore, the privacy protection requirements are different from those in the academic documents verification system based on blockchain. Therefore, the local database should also establish a corresponding hash value of the private transaction data and implement mapping with the private database on the chain to achieve traceability based on the same hash value.
