Privileged-Based Secure Sharing of Student's Credentials using Blockchain Technology and Secret Image Sharing Scheme

Any educational ecosystem that comprises a wide range of stakeholders, including students, teachers, various institute committees, administrations, government agencies, and many more, must have a framework in place for the sharing of students' credentials. All of these stakeholders take extensive steps to ensure the authenticity and confidentiality of shared student testimony. Despite these concerns, the distribution of students' credentials is a vulnerable, potentially complex, and sometimes insecure process. The aim is to use blockchain technology and secret-sharing scheme to mitigate existing security concerns when sharing the students' credentials. Due to the immutable nature of blockchain technology, the problem of safely exchanging student credentials can be resolved using blockchain technology. This paper proposes a privileged system for storing student credentials that ensures security and privacy while sharing sensitive credentials with other parties. This can be achieved by combining blockchain technology with the SIS (secret Image Secret Sharing) scheme and IPFS (Interplanetary File System), giving students the privilege of sharing their information. Moreover, to ensure limited access and enhanced privacy, the system also includes student privilege management. As a result, the proposed scheme provides tamper-proof, immutable, authentic, non-repudiation, privacy-preserving exchange of student credentials among stakeholders.
