Microsoft is releasing a second Community Technology Preview (CTP) of U-Prove and related software innovations to help put users in control of how their identity information is shared on the internet. Microsoft is pleased to announce this preview during RSA 2011,  and to enable policymakers, end-users, and members of the Internet Identity community to try out the concepts, evaluate the capabilities and provide feedback.


U-Prove is an advanced cryptographic technology that, combined with existing standards-based identity solutions, overcomes the long-standing dilemma between identity assurance and privacy. U-Prove technology offers the same level of security as X.509 certificates, with additional privacy protecting features. These capabilities unlock a broad range of scenarios that have historically been out of the reach of both the private and public sectors - cases where both verified identity information and privacy are required.


At the core of Microsoft’s vision are U-Prove Agents—software that acts as an intermediary between websites and explicitly represent the users’ interests in choosing to share (or not to share) their personal information with sites on the Internet. In this Preview, Microsoft offers a U-Prove Agent running as an online service, accessible from any computing device with a web browser. Optional client-side software delivered by this service provides enhanced security and privacy capabilities.
This Preview also includes several sample websites, representing organizations in public and private sectors that can issue verified information or consume this information.

Industry Working Group for a Claims Agent

To further the practical collaboration on privacy protecting solutions among open source and commercial partners, Microsoft is working within the Identity Commons helping to form a new working group. The charter for the Claims Agent Working Group includes sponsoring open source variants of a U-Prove Agent, testing for interoperability among common browsers and platforms, and testing specific scenarios in an end-to-end manner in order to build confidence in the identity and privacy ecosystem.

Testing the Microsoft U-Prove Agent

For testing purposes, Microsoft has created several sample websites, representing organizations in public and private sectors that can issue verified information or consume this information. These sample sites have been setup with fictitious user accounts and fictitious user data.

 Instructions for using these sample websites is available on the sample websites page.
