AbstractOne 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., we 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. The properties and efficiency for selecting the most useful parameters to provide a high level of security in the scheme are thoroughly analyzed. © 2012 Elsevier Inc. All rights reserved.
