Windows CardSpace 2.0 'R.I.P.', U-Prove Coming to Live

CardSpace, which got its start as "Windows InfoCard," attempted to represent an individual's digital identity that the user could use to communicate with a third party entity. According to a blog post, "In spite of the elimination of CardSpace, Microsoft is still a big proponent of claims-based identity concepts, and the company has baked support for these identity solutions into SharePoint, Office 365, Dynamics CRM, and Windows Azure."

"Windows CardSpace was initially released and developed before the pervasive use of online identities across multiple services. Perhaps more importantly, we released the user component before we and others had delivered the tools for developers and administrators to easily create claims-ready services. The identity landscape has changed with the evolution of tools and cloud services. Based on the feedback we have received from partners and beta participants, we have decided not to ship CardSpace 2.0," writes Microsoft's Claims-Based Identity team.

Microsoft has been a leading participant in the identity community and an active contributor to emerging identity standards. We've increased our commitment to standardization activities and added support into our products for the SAML 2.0, OpenID 2.0, OAuth WRAP and OAuth 2.0 protocols.

Microsoft is also releasing a new technology preview of U-Prove. This release of U-Prove will take the form of a user agent that takes account of cloud computing realities and takes advantage of the high-end security and privacy capabilities within the extended U-Prove cryptographic technology.

The Agent is "software that acts as an intermediary between websites and allows sharing of personal information in a way that helps protect the user's privacy," the U-Prove Frequently Asked Questions (FAQ) document explains. U-Prove is based on technology that Microsoft bought when it acquired Credentica in 2008.
