Security Efficiency Analysis of a Biometric Fuzzy Extractor for Iris Templates
A Biometric fuzzy extractor scheme for iris templates was recently presented in [3]. This fuzzy extractor binds a cryptographic key with the iris template of a user, allowing to recover such cryptographic key by authenticating the user by means of a new iris template from her. In this work, an analy...

| Sumario: | A Biometric fuzzy extractor scheme for iris templates was recently presented in [3]. This fuzzy extractor binds a cryptographic key with the iris template of a user, allowing to recover such cryptographic key by authenticating the user by means of a new iris template from her. In this work, an analysis of the security eficiency of this fuzzy extractor is carried out by means of a study about the behavior of the scheme with cryptographic keys of diff erent bitlengths: 64, 128, 192, and 256. The diff erent sizes of the keys permit to analyze the variability of the intra- and inter-user in the iris templates. |
