A privacy-preserving identity card is a personal device device that allows its owner to prove some binary statements about himself (such as his right of access to some resources or a property linked to his identity) while minimizing personal information leakage. After introducing the desirable properties that a privacy-preserving identity card should fulfill and describing two proposals of implementations, we discuss a taxonomy of threats against the card. Finally, we also propose for security and cryptography experts some novel challenges and research directions raised by the privacy-preserving identity card.
