Introduced by cryptographer Dr. <B>Stefan Brands<\/B> in 2004, it took the industry by storm (<A href=\"http:\/\/www.schneier.com\/blog\/archives\/2008\/02\/credentica.html\">1<\/A>,&nbsp; <A href=\"http:\/\/www.identityblog.com\/?p=778\">2<\/A>). In 2008 <A href=\"http:\/\/www.identityblog.com\/?p=934\">Microsoft acquired the technology<\/A> and hired Stefan &amp; his crew (<B>Christian Paquin<\/B>, <B>Greg Thompson<\/B>) in the identity and access division. They have been busy ever since to integrate U-Prove in the Identity Metasystem: today we can finally let the world give a first glance to their work.<\/P><br \/>\n<P>Today, March 2, 2010, at the RSA Security Conference, Microsoft is taking a first step to make the U-Prove technology available to the public and interested parties: <\/P><br \/>\n<UL><br \/>\n<LI>First, we are <B>opening up the U-Prove intellectual property<\/B> with a cryptographic specification under the Microsoft <A href=\"http:\/\/www.microsoft.com\/interop\/osp\/default.mspx\">Open Specification Promise<\/A> (OSP).&nbsp; <B>Two open source software toolkits are being made available<\/B>&#8212; <B><A href=\"http:\/\/code.msdn.microsoft.com\/uprovesdkcsharp\">C#<\/A> and <A href=\"http:\/\/code.msdn.microsoft.com\/uprovesdkjava\">Java<\/A><\/B> editions&#8211; so the broadest audience of commercial and open source software developers can access the technology. <\/LI><br \/>\n<LI>Second, we are <B>releasing a public <A href=\"http:\/\/www.microsoft.com\/uprove\">Community Technology Preview (CTP<\/A>)<\/B>, which integrates the U-Prove technology with the Microsoft identity platform technologies (Active Directory Federation Services 2.0, Windows Identity Foundation, and Windows CardSpace v2).
