Biometric cryptosystem can not only provide an efficient mechanism for template protection, but also facilitate cryptographic key management, thus becomes a promising direction in information security field. In this paper, we propose a robust key extraction approach which consists of concatenated coding scheme and bit masking scheme based on iris database. The concatenated coding scheme that combines...
The combination of biometrics and cryptography is a promising information security technique which offers an efficient way to protect the biometric template, as well as to facilitate user authentication and key management. We propose a key-binding scheme based on iris data, in which reliable region is selected to reduce the intra-class variation, and error control technique that combines RS and convolutional...
