Abstract


As Augmented Reality (AR) in Science, Technology, Engineering, and Mathematics (STEM) education is emerging, the problem of securing and verifying digital content is becoming a central challenge. This study proposes a blockchain-based augmented reality framework to improve the authenticity and security of educational content in Tanzania's STEM education system. The framework consists of five main components: a content submission portal, a blockchain ledger, a digital certificate of authenticity issuance system, a content verification system, an integrity check, and an access control system. Together, the system ensures that the content remains authentic. Moreover, algorithms are developed to hash the AR content and compare it against the hash of the content stored on the blockchain to verify the content before access is given. A set of experts was invited to validate the technical soundness, feasibility, and alignment with the centre's educational standards. Future work aims to improve the decentralization level of the framework and test the impacts of the platform on the academic outcomes of users in real-world settings.
