"WebID is an authentication protocol which uses X.509 certificates to associate a User Agent (Browser) to a Person identified via a URI. WebID is compatible with OpenID and provides a few additional features such as trust management via digital signatures, and free-form extensibility via RDF. By using the existing SSL certificate exchange mechanism, WebID integrates smoothly with existing Web browsers, including browsers on mobile devices. WebID also permits automated session login in addition to interactive session login. Additionally, all data is encrypted and guaranteed to only be received by the person or organization that was intended to receive it."
