Age verification is increasingly mandated by law, especially in online services. In this paper, we present a proof-of-concept protocol for privacy-preserving age verification. Our approach allows users to prove compliance with age requirements without revealing their identity to the service provider. Furthermore, the website remains unaware of which authority issued the age certification, and the certification authority does not learn which website is making the request or the specific age being verified. This design ensures strong privacy guarantees for all parties involved. Its properties served as a baseline for part of the reference document published by the French regulator ARCOM.
