A privacy enhanced identity scheme that may use public and private key cryptography to selectively distribute attributes of a token holder to a relying party. A challenge message {Rnonce, RID}, where Rnonce is a reader nonce and RID is a reader identifier. Methods may also include, responsive to the challenge message, sending a response message including at least an encrypted private token identifier TID and a session key k. In response to a challenge from a reader. The token sends a message that includes token identifier that is un-linkable to other identifiers sent from the same token. ® KIPO & WIPO 2009 |
