Privacy-preserving Diploma Management System based on Blockchain

In this paper, we proposed the privacy-preserving diploma management system (P2DMS) based on blockchain. Since the learning curve and cost are too high to operate a blockchain network, most schools outsource blockchain-based DMS. However, the challenges of outsourcing blockchain-based DMS include a lack of data privacy and man-in-the-middle attacks. P2DMS utilizes data encryption and digital signature algorithms to ensure data privacy and to prevent man-in-the-middle attacks while outsourcing blockchain-based DMS.
