IBM and Microsoft just published the specification “Application Note: Web Services Addressing Endpoint References and Identity” at http://schemas.xmlsoap.org/ws/2006/02/addressingidentity/. This specification is referenced by the Identity Selector Interoperability Profile (ISIP) and is covered by Microsoft’s Open Specification Promise (OSP). This completes the publication and licensing under the OSP of all specifications that Information Cards [...]

Relying Parties often identify subjects using the Private Personal Identifier (PPID) claim and Signing Key values sent by an Information Card. Thus, it is important that the PPID and Signing Key values produced by a card be stable and long-lived. Unfortunately, the PPIDs and Signing Keys generated by self-issued (a.k.a. personal) Information Cards using the [...]

I am pleased to announce the publication of the Identity Selector Interoperability Profile V1.5 and companion guides. The ISIP (as it’s come to be called) documents the protocols and data formats used by Windows CardSpace so as to enable others to build compatible Information Card software. Version 1.0 of these documents corresponded to the.NET Framework [...]

Non-Microsoft applications will have the same ability to use "InfoCard" to manage their identities [...]

Following on the Interops at IIW in May and Catalyst in June , the participants continued their joint work of ensuring that the identity software we’re all building works great together.
