Digital Credentials Offer Enhanced Privacy

John Q Random writes _“[Stefan Brands][1]‘s company credentica.com announced their [U-Prove library and SDK implementing ID tokens][2] â€�? also known as [digital credentials][3] or private credentials. (Private Credentials are a cool PKI replacement and anonymous e-cash tech that allows you to prove certified attributes like age, credit rating, group membership, etc. without revealing who you are; to allow you to have a digital life without the digital dossier effect inherent in a central databases.) Following this announcement, [Adam Back][4] [announced][5] [credlib][6], an open source implementation of Brands credentials (and the older more basic Chaum certificates). These developments relate to recent news from IBM’s Zurich labs on their [identity-mixer][7] project (previously [discussed on Slashdot][8]) that is based on the less efficient Jan Camenisch and Anna Lysyanskaya credentials.” From Slashdot: http://yro.slashdot.org/article.pl?sid=07/02/20/2158240&from=rss
