1. Certificate PDFs are hashed to find unique, irreversible digital fingerprint.
2. Digital fingerprints are digitally signed by the issuer and published onto Polygon Blockchain.
3. Unqiue blockchain proofs are computed and attached to Certificate PDF to form blockchain-enabled certificate, subsequently issued to students.
1. Verifier uploads Certificate_legitdoc.pdf to the verification portal.
2. Verification portal parses and extracts Blockchain proof out of blockchain-enabled Certificate PDF.
3. Verification portal calculates PDF fingerprint; Compares fingerprint and Blockchain proof data with the data put on the Blockchain for verification.
