Abstract

In this paper, we propose a novel finger vein based cancelable biometric key generation scheme. Three main steps are involved in the proposed scheme: (i) Finger vein feature is extracted by maximum margin locality preserving projection (MMLPP); (ii) Chaotic random projection was used for cancelable biometric template generation; (iii) Construct a fuzzy commitment based key generation system. Experiment and analysis show our proposed scheme is a secure and efficient key generation scheme.
