Interesting news: According to the posts over at identity corner, Microsoft is picking up (some of? all of?) Credentica's patent portfolio, and Stefan Brands himself will join the team.
Brands has one (of two) lineages of patents on digital blinding, the other one was via David Chaum, and is now lost somewhere in some bank's hands due to bankruptcy. Though Chaum was working on something new, haven't heard anything about that . . . Anyhow, this means Microsoft is in control of the current state of the art for digital money, and identity management.
Congratulations - it must have been a fantastic monetary offer to make you withdraw credentials from the open market like this and hand over control of identity to MS.
This just set [Privacy Enhancing Technologies] back many years.
And Kim Cameron (Microsoft) has a great round up of the PR and reactions in the wake of the announcement at identityblog: Reactions to Credentica acquisition
He ends with:
That doesn’t mean it is trivial to figure out the best legal mecahnisms for making the intellectual property and even the code available to the ecosystem. Lawyers are needed, and it takes a while. But I can guarantee everyone that I have zero intention of hoarding Minimal Disclosure Tokens or turning U-Prove into a proprietary Microsoft technology silo.
Sure you don't, but what about your evil overlords?
