Blockchain Integration for Scantron System

As an educational institution, we want to integrate blockchain technology into our Scantron testing system to ensure the security and verifiability of test results on desktop, mobile, and tablet platforms.

Acceptance Criteria

• The system supports the creation of digital test records as blockchain transactions.
• Each submitted test is recorded as a unique and immutable transaction on the blockchain.
• Instructors can view the transaction on the blockchain to verify test submission authenticity.
• Students can securely access their test results using a blockchain-based verification system.
• Integration does not compromise the existing Scantron system usability across desktop, mobile, and tablet interfaces.
• The system adheres to GDPR and other relevant data protection regulations for handling personal information.
• The blockchain solution facilitates smart contract usage to automate result processing.
• There’s a mechanism for resolving disputes or errors in test submissions recorded on the blockchain.
