In this chapter, we describe how to perform a secure and efficient IrisCode-based identification. In this use case, the first party has an IrisCode, the second party has one or several IrisCodes and they would like to discover whether the first party's IrisCode is close to at least one IrisCode belonging to the second party without revealing any information about their own IrisCodes to the opposing party. Secure Two-Party Computation (S2PC) protocols are dedicated to this use case because they enable two parties to jointly evaluate a function over their inputs while preserving the privacy of their inputs. In this chapter, we explain how to efficiently use S2PC protocols for secure iris-based identification.
