Research in the International Journal of Information and Communication Technology has looked at potential security and privacy weaknesses in remote higher education systems, focusing on centralized virtual learning platforms.
The researchers explain that these platforms usually rely on a single administrative infrastructure for authentication, records and content delivery. This, they suggest, creates a single point of failure, where disruption or compromise of the central system might affect the entire environment. This could open up the possibility of data tampering, credential fraud and unauthorized access, while undermining trust in online degrees.
The team suggests that blockchain technology, usually associated with digital or cryptocurrencies, has the potential to protect education systems, making them tamper-proof. Earlier work allowed simple static credential storage. But the new approach is dynamic and could be used for enrollment, course access and ongoing assessment, rather than serving mainly as a certificate verification system.
The team's proposal of Blockchain-Enabled Secure Distance Learning (BESDL) represents a lifecycle-based framework covering the full education process. It uses smart contracts, self-executing rules on a blockchain, to manage decentralized identity management, secure content-based access control and encrypted content delivery.
