Microsoft used to refer to WS-* as the identity metasystem, as if you couldn't achieve the defining heterogeneity without WS-Trust et al to tie it all together. That's why it's nice to see the Cardspace book acknowledge this (albeit indirectly). Use of 'the' when an 'a' would be more appropriate does remain . I did get a chuckle out of for the purpose of understanding the concepts presented in this book, you can safely ignore the protocol portion of SAML. The ostrich strategy may not be working out Read More...

The Organisation for Economic Cooperation and Development (OECD) this week released At a Crossroads: Personhood and Digital Identity in the Information Society, by Berkman Fellow Mary Rundle and co-authors Bob Blakley, Jeff Broberg, Anthony Nadalin, Dale Olds, Mary Ruddy, Marcelo Thompson Mello Guimarães, and me.
The paper describes user-centric “properties of identity” that can guide [...] Read More...

Why are there not levels of 'greenness', as in identity assurance ? Green Seal provides science-based environmental certification standards that are credible, transparent, and essential in an increasingly educated and competitive marketplace. FSC is an international certification and labeling system that guarantees that the forest products you purchase come from responsibly managed forests and verified recycled sources. EcoLogo is North America’s most widely recognized and respected certification Read More...

This is such a smart move of Microsoft! I am impressed and I am sure that Credentica's technology will lead to a privacy improved version of CardSpace. I hope that Microsoft will provide open access to this technology for others to implement identity selectors, relying parties and security token servers. CardSpace is token agnostic but when I have read the U-Prove papers correctly then there is more then one roundtrip between id selector and STS required to deliver all the nice features. The protocol Read More...

This past Monday, Bret Taylor (FriendFeed), Ian Kennedy (MyBlogLog), Kevin Marks (Google) and I spoke about the role of feeds in social networking. We talked both about some of the technical aspects of RSS and Atom feeds (such as the endless re-feed problem) as well as feeds from a feature perspective such as the Facebook News Feed, Six Apart's Movable Type Action Streams, FriendFeed, MyBlogLog, etc. We also touched on some issues of data portability, ownership, and privacy. I think we were a pretty Read More...

Stefan and his team are rock stars in privacy-enhancing crypto. Today their technology and patents were acquired by Microsoft as you can read here, here and here. I want to congratulate Stefan personally. Here’s a fellow entrepreneur, and someone I’m honored to call a friend who’s done it all. Developed a deep technology, created a [...] Read More...

The news just become official that Microsoft has acquired Stefan Brand’s Credentica and all its intellectual property. This pairs up Stefan with Microsoft’s Identity and Access team to bring Credentica’s groundbreaking U-Prove zero-knowledge-proof technology to market.
This is a very exciting development, particularly because it means that between Microsoft’s work on CardSpace and Higgins work on [...] Read More...

Across the wires this morning comes news from Kim and Stefan that Microsoft has acquired Credentica 's U-Prove technology and the services of Stefan and his Credentica colleagues. I'm curious as to why the news isn't simply 'Microsoft acquires Credentica', but business is sometimes like that, I guess. Anyway, congratulations to Stefan and co! I've been following their technology for a few years now (I even worked my way through Stefan's book - well, most of it - some of the formal proofs were a little Read More...

In announcing Microsoft's purchase of the Credentica patents (and hiring of Stefan's core team), Kim uses the 'need to know' analogy. That danger can be addressed by adopting a need-to-know approach to the Internet. (For the life of me, I just cannot get Sgt Shultz's 'I know nothing' out of my head.) Credentica's U-prove technology promises to close off a (depending on the deployment environment, potentially big) 'knowledge leak' - if the IDP doesn't need to know what/where/why/when/who the user Read More...

I am thrilled to announce that Microsoft has acquired Credentica’s U-Prove™ technology, together with all of the underlying patents. Microsoft plans to integrate the technology into Windows Communication Foundation and Windows Cardspace. Check out the blogs of Kim Cameron and Microsoft’s Corporate Privacy Group for more information.
In addition, I and my stellar colleagues Greg Thompson [...] Read More...
