Privacy-preserving age verification that never learns who you are.
Issues signed age-band credentials without storing names, birthdates, or ID images. Six REST endpoints cover registration, authentication, scoped token issuance, field-level access control, and instant revocation, with JWT auth and bcrypt hashing. Built in a 24-hour window at HackFax x PatriotHacks 2026, where it took 2nd place in both the Cybersecurity and Gemini API tracks.
