Preserving the Privacy for University Data Using Blockchain and Attribute-based Encryption

An effective IT solution is required for the administrative processes which is the core of university. The tamper resistance, transparency and auditability for university management data are very important to avoid the corruption. Blockchain occupies the immutability and irreversibility properties thus, it becomes a potential solution. Regrettably, there are some challenges such as privacy concern and limited storage exists in blockchain technology. In this work, a blockchain-based university data storage model is proposed and such barriers of blockchain are handled. The proposed model achieves the tamper resistance, transparency and auditability feature by using blockchain technology. CP-ABE and other cryptographic techniques are used to provide the fine-grained access and privacy preserving facilities. The security analysis is performed and shows that our approach is tamper resistant and provably secure for privacy.
