PileumConnect is a public OpenID Connect Provider designed for proof of personhood and privacy.

Users must own a french electronic national identity card to register an account and prove their identity. The user's identity is processed directly in the browser, ensuring it is never transmitted over the internet.

Any OpenID Connect Relying Party can use the service to authenticate its users : the only user information provided is a Pairwise Pseudonymous Identifier (PPID). PPID is the identifier of a User to a Relying Party and cannot be correlated with the User's PPID at another Relying Party.

PileumConnect also extends the official OpenID Connect specifications with EIP-712 signatures to make authentication responses compatible with Ethereum smart contracts.
