It was announced today that Microsoft has purchased Credntica's U-Prove technology.
Trust (and privacy) is a key aspect of connectedness. We share more with people we trust and less with those we don't. As Kim Cameron puts it, U-Prove works on a "need to know" basis. If a web site proves worthy we might share more details and the Info Card with U-Prove will make that easier to accomplish.
We will eventually see adoption of Info Cards as a mechanism. Adoption is slow but this bit of news will undoubtedly move things along.
