Verification Of Integrity And Secrecy Properties Of A Biometric Authentication Protocol

In this paper, we clarify and verify an established biometric authentication protocol. The selected protocol is intended to have three properties: effectiveness (integrity checks are carried out on all hardware before enabling transmission of biometric data), correctness (the user is satisfied that integrity checks have been executed correctly before transmission of biometric data occurs), and secrecy (unauthorized users cannot obtain biometric data by intercepting messages between the system's hardware components). We analyse the clarified protocol using applied pi calculus and the ProVerif tool, and demonstrate that it satisfies the intended proper-ties of the protocol. Moreover, this paper shows that the verification result between the naive interpretation and the clarified interpretation is different.
