U-Prove is a credential system that allows users to disclose information about themselves in a minimalistic way. Roughly speaking, in the U-Prove system a user obtains certified cryptographic tokens containing a set of attributes and is able to disclose a subset of his attributes to a verifier, while hiding the undisclosed attributes. In U-prove the actual identity of a token holder is hidden from verifiers, however each token has a static public key (i.e. token pseudonym), which makes a single… CONTINUE READING
