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 [...]

I found the samples very clear, and uncluttered with a lot of "sample decoration"

Microsoft recently created a Consumer Website for CardSpace to educate end-users about Windows CardSpace and Information Cards. This complements the developer-focused information at the MSDN CardSpace site and the CardSpace Community Site. No, it’s not the kind of content targeted at regular readers of this blog – especially the short video – but then, that’s [...]

Kim Cameron and I recorded a podcast on digital identity for MySuccessGateway this week at the invitation of Jim Peake of SpeechRep Consulting. Jim was a gracious, informed, and enthusiastic host during our conversation, which covered a wide range of digital identity topics including identity theft, shared secrets, privacy, Information Cards and the Information [...]

Last week IDology demonstrated a first that many of us see great possibilities for: an Information Card making a verified age claim. I’m excited at this first step towards the goal of enabling people to routinely use interoperable verified claims about themselves via Information Cards. Obtaining my age-verified card online was easy. I submitted my name, address, and birth date (via a self-issued card) to IDology’s verification process. Next they asked me a few additional questions to confirm that

In May 2005, when I wrote the whitepaper “Microsoft’s Vision for an Identity Metasystem”, these sentences were aspirational: Microsoft’s implementation will be fully interoperable via WS-* protocols with other identity selector implementations, with other relying party implementations, and with other identity provider implementations. Non-Microsoft applications will have the same ability to use "InfoCard" to manage their identities [...]

Information Cards take a familiar off-line consumer behavior – using a card to prove identity and provide information – and bring it to the online world
