attester.no proves a certificate is genuine without storing information about you.
Only the QR code on the certificate carries your personal data. When someone scans the code, the verification page computes the fingerprint of the data in the code and compares it with the fingerprint we stored when the certificate was issued. If they match, the certificate is genuine and unaltered. Change as little as one character and they no longer match.
A certificate you can trust, and an organization that does not have to look after your data. Everybody wins, and nobody is left guarding an archive.
