Blockchain Based-Student Credit Bank Records in Guinea Education System

Nowadays, despite the continuous advancement of digital technologies, several countries in sub-Saharan Africa, notably Guinea, face several challenges in managing academic records (main units of the educational ecosystem). Issues are mainly related to storage, availability, privacy, sharing, integrity, access control, and interoperability of data across stakeholders, leading to additional difficulties, namely data loss, security breaches, lack of data continuity, and a high profile of fraud cases. Our goal is to take advantage of blockchain technology's potential to address these issues. As a result, this approach presents novel blockchain-based system architecture for the secure storage, issuance, sharing and efficient access control of student academic records among relevant stakeholders while protecting student privacy. In the proposed framework, student academic records are stored securely, scalable, immutable, and authenticated using Hyperledger fabric, IPFS, chain codes, and encryption techniques with specific access control mechanisms involving only authorized stakeholders. The study carried out a system design starting from the aspects of the registration of the users, the management of the academic records attributed to the students, access control to other functionalities. It also uses UML Diagrams to grasp and depict the concept of the proposed solution
