U-Prove is a Microsoft technology for user-centric identity management. The underlying cryptographic protocols were designed by Dr. Stefan Brands and further developed by Credentica.[1] U-Prove enables application developers to reconcile seemingly conflicting security and privacy objectives (including anonymity), and allows for digital identity claims to be efficiently tied to the use of tamper-resistant devices such as smart cards. Application areas of particular interest include cross-domain enterprise identity and access management, e-government SSO and data sharing, electronic health records, anonymous electronic voting, policy-based digital rights management, social networking data portability, and electronic payments.
In 2008, Microsoft committed to opening up the U-Prove technology.[2] As the first step, in March 2010 the company released a cryptographic specification and open source API implementation code for part of the U-Prove technology as a Community Technology Preview under Microsoft's Open Specification Promise.[3] Since then, several extensions have been released under the same terms and the technology has been tested in real-life applications.
