Academic Information Storage and Verification Using Blockchain Technologies

In general, academic verification of an employee is done manually takes a lot of time, cost and less trustworthy. The trustworthiness of the certificate is dependent on the employee. Due to financial benefits and other advantages, fake certificates are easily created by fraudulent members. Detecting a fraudulent certificate is a hard process. Nowadays, blockchain technology provides wonderful benefits to all sectors for maintaining documents in an immutable manner. Once the data is stored in a blockchain, no one can change or delete that data. Hence, blockchain technology is used to store and verify academic information is highly scalable and guaranteeing the privacy of users’ data. In a proposed work, the blockchain network is created between the educational institutions and employers for efficient information sharing and verification. For unique identification of the certificates QRcode is assigned to each academic certificate. By using SHA256 algorithm the hash value of the QRcode is calculated and has been stored in a block in a distributed ledger. The employer calculates the hash value of the certificate which is submitted by the employee and compared this hash value to the hash value of the certificate stored in the block. If both are equal, the employer identifies it’s a valid certificate or else rejected it’s invalid certificate. Thus, trustworthy verification like confidentiality, authentication, authorization, ownership and privacy is achieved through blockchain technology. Likewise, the certificate verification latency is reduced and throughput is increased in this approach.
