A Blockchain Based Decentralized Certificate Management System Using Hyperledger Fabric

Abstract

The development of blockchain has influenced various fields, including Banking, healthcare, fiśnancial and supply chain systems. At present, this technology is applied in the education sector and its unique features like decentralization, trustworthiness and security have added revolutionary characteristics to existing systems. An individual deals with a variety of certificates in daily routine life which includes voter ID, land documents, marriage documents, vehicle documents and health documents. These documents showcase an individual’s capabilities, achievements, strengths in terms of educational, extracurricular and professional certificates. Management of digital copy of these certificates became the main motive and the hardcopy perseverance became obsolete. The digital certificates help us to preserve and showcase an individual’s capabilities for career growth. These certificates can be forged and misused for self motives. Need to secure these certificates against frauds. A variety of systems exist to manage these certificates and to thwart forgery. Traditional method of certificate storage involves usage of a centralized database or a web server for certificate storage which is vulnerable to theft and forgery. Best alternative is a Blockchain based system. Different Blockchain based certificate management systems and their drawbacks are discussed and will propose a hybrid model of educational certificate management model using Hyperledger Fabric, IoT and 2D Barcode.
