Research question
Verifying a qualification usually means emailing the university and waiting days, which makes forged certificates easy to pass off.
Approach
Each issued certificate is recorded in an append-only, hash-chained log; a QR code on the certificate lets anyone check it against the log.
Key features
- Instant verification from a QR code
- Tamper-evident, append-only record of issued certificates
- Students control who can see their full record
Evaluation
The design was analysed against common forgery and tampering scenarios and load-tested for graduation-season traffic.
