Abstract

The quantity of fraudulent certificates in circulation is a major issue we face today, and it is a widespread one. Day-to-day development of academic information security is essential in Blockchain technology has become an influential paradigm in education. Objectives: This paper presented an innovative recommendation system for privacy-preserving originality of academic certificates and prevent fake certifications. Methods:In order to accomplish secure and trustworthy exchange of student credentials this paper propose a HLEeCERT blockchain based application to fake prevention method based on hashing and smart contracts in order to classify the attack thoroughly. The proposed system was implemented using the Hyperledger fabric network with MongoDB, Node.js, and Go Lang with hyperledger caliper benchmark tool and Python 3.8 were used at the client side. Findings: Proof of Validity smart contract is developed and deployed two different blockchain network to provide data security. The system performance are analyzed and compared with existing blockchain network using hyperledger fabric caliper benchmark tool to evaluate the performance of proposed HLEeCERT frameworks on various aspects, including response time, throughput, and transaction overhead, were performed. Novelty: This work proposes a new method Proof of Validity consensus protocol as smart contract that uses a hyperledger block-chain that records the hash value of students’ academic certificates and a trusted employer third party to verify the certificates hash values, thereby avoiding recording the duplicate certificates throughout the hyperledger block-chain.
