This paper aims to provide a remote fingerprint object authentication protocol dedicated to anti-counterfeiting
applications. The corresponding security model is given. The suggested scheme is based on an Elliptic Curve
Cryptography (ECC) encryption adding a mechanism to control integrity at the verification stage. The
privacy constraint useful in many applications leads us to embed a Private Information Retrieval scheme in
As in a previous SPIE presentation, we begin with an optical reader. We drastically lower the amount of
computation made at this stage.
This paper follows a paper by Bringer et al.<sup>3</sup> to adapt a security model and protocol used for remote biometric
authentication to the case of remote morphometric object authentication. We use a different type of encryption
technique that requires smaller key sizes and has a built-in mechanism to help control the integrity of the messages
received by the server. We also describe the optical technology used to extract the morphometric templates.
