A Crypto-Biometric Scheme Based on Iris-Templates with Fuzzy Extractors

One of the most important uses of Biometrics is the identification and authentication of individuals using one or several of their physiognomical or behavioral features. Moreover, Biometrics offers a good option to assist Cryptography for confidentiality, encryption, and decryption of messages by using some biometric traits. In this paper, a crypto-biometric scheme, based on fuzzy extractors, by using iris templates, is proposed, i.e., the authors propose a new system in order to permit a user to retrieve a secret or a previously saved key by using her own biometric template.
