Methods, apparatus, and computer program products are herein described that provide for an identity-based cryptosystem using a highly secure biometric model through which both access and data transmission are effectively made very secure. Through implementation of generating and securely storing biometric data as syndrome vectors tolerance is provided for the inherent variability of biometric data. In addition, to insure that the biometric data is not duplicated by adversaries who might gain access to the syndrome generation algorithm and the biometric data, present aspects, provide for keeping the private key more secure and making the cryptosystem user-identity dependent. As such the systems, apparatus and computer program products herein disclosed provide end-to-end authentication of end users using secure biometry, which constitute the symmetric and/or asymmetric identity-based cryptosystem.
