A '''trust federation''' is part of the evolving [[Identity Metasystem]]  that will bring a new layer of persistent identity and trusted [[data sharing]] to the Internet. Although the concept of trust federations is technology neutral, several protocols like [[Security Assertion Markup Language|SAML]], [[OpenID]], [[Information Card]], [[XDI]] can handle the challenges of technical interoperability. The challenge of business and social interoperability requires a new type of cooperative association similar to a credit card association. Instead of banks, however, a trust federation is an alliance of i-brokers and their customers who agree to abide by a common set of agreements in the care and handling of customer data. A model for trust federations is offered by [http://openidentityexchange.org/node/44 Open Identity Exchange] and [http://kantarainitiative.org/ Kantara Initiative], which is applied in the [http://www.idmanagement.gov/drilldown.cfm?action=icam U.S. Government ICAM Trust Framework].

Some operational trust federations<ref>{{Cite web| url =http://kantarainitiative.org/confluence/display/bctf/Implemented+Trust+Frameworks | title= Kantara Initiative: Implemented Trust Frameworks}}</ref> are:
* [http://www.incommon.org/ InCommon] (academic, USA)
* [http://www.terena.org/activities/refeds/ REFEDs] (Research and Education Federations, Europe)
* [http://www.igtf.net/ IGTF] Interoperable Global Trust Federation
* [http://www.portalverbund.at/ Portalverbund] Government Portal Federation, Austria

Trust federations are not limited to the social web use case, but apply to all federations where trust in identity and compliance to other objectives of information security such as confidentiality, integrity and privacy is brokered.
