Liberty Alliance


The Liberty Alliance is an industry consortium defining standards for federated identity – including enabling simplified sign-on through federated network identification using current and emerging network access devices, as well as supporting and promoting permission-based attribute sharing to enable a user's choice and control over the use and disclosure of his/her personal identification.

The group was originally conceived and named by Jeff Veis, at Sun Microsystems in 2002

Liberty Alliance defined:

Liberty's Identity Web Services Framework (IDWSF), a platform for securing identity-based web services, continues to evolve within the Liberty Alliance. Liberty ID-WSF uses SAML assertions as the security token format by which the authentication and authorization information associated with the various web service actors are communicated amongst them.

Kantara Initiative took over the work of the Liberty Alliance in 2009
