InfoCards＋"Web Application"

おおー

The Identity Metasystem allows users to manage their digital identities from various identity providers and employ them in different contexts where they are accepted to access online services. In the Identity Metasystem, identities are represented to users as "Information Cards" (a.k.a. "InfoCards"). One important class of applications where InfoCard-based authentication can be used is applications hosted on Web sites and accessed through Web browsers.
