Microsoft has acquired U-Prove, which allows internet users to disclose only minimal personal information when conducting electronic transactions, to reduce the likelihood of privacy violations. U-Prove also employs cryptography to prevent systems from pulling together information about users from various sources.
Microsoft plans to integrate U-Prove into Windows Communication Foundation and CardSpace. WCF is built on the .Net framework and allows programmers to build and run connected systems. CardSpace is also technology built on .Net that developers use to build software and websites that are less susceptible to common identity attacks like phishing. CardSpace is used in sites that support shopping, banking and bill payment.
The purchase price was not disclosed.
