Information Cards, the identity specification developed by Microsoft, is headed to a standards body that will work to ensure interoperability among implementations and adoption as a standard authentication method across the Internet.

The Organization for the Advancement of Structured Information Standards (OASIS), which is known for hammering out Web services standards, has created the OASIS Identity Metasystem Interoperability (IMI) Technical Committee. The group plans to hold its first meeting Sept. 29 in London.

This is the first effort to take the user-centric identity model championed by Microsoft and others such as Novell, Oracle and IBM and have it standardized for use across platforms and across the Internet.

Microsoft's InfoCard technology and its user interface implementation called CardSpace presents users with an identity selector interface, basically a palette of secure identity cards, that can be used to authenticate to various Web sites or network resources such as applications or databases. It is all part of the company's Identity Metasystem that also includes back-end servers and gateways for exchanging cards and the data they contain.

The OASIS group will focus on making sure implementations of the Information Cards technology, first introduced by Microsoft in 2005, are interoperable. It will not create an entirely new specification.

The foundation of the IMI's work will be built around the Identity Selector Interoperability Profile from Microsoft, the Web Services Addressing Endpoint References and Identity specification from IBM and Microsoft, and the Open Source Identity Systems (OSIS) Feature Tests from Identity Commons.

The IMI group said in a statement that it would "assure the portability of Information Card content by defining a standard method of transferring collections of Information Cards between Identity Selectors." The group says Information Cards have relevance to Web 2.0, consumer and corporate intranet applications.

"Having things be real standards created by internationally recognized standards bodies is important for adoption in certain sectors such as government and telcos," says Mike Jones, director of identity partnerships for Microsoft and the author of the Identity Selector Interoperability Profile. Jones says the expectation is that other organizations such as the ITU would recommend the use of the IMI's eventual standard.
