Biometric encryption using fingerprint fuzzy vault for FPGA-based embedded systems

This paper discusses a biometric encryption system using fuzzy vault scheme implemented on FPGA development board. Cryptographic algorithms are very secure overall but have a weak point in terms of the storage of the crypto keys. Biometric authentication systems have many exploitable weak points that can be used to compromise the system. Biometric encryption is a security scheme that combines strong cryptographic algorithms with biometric authentication to provide better security. This paper discusses a simple implementation of a biometric encryption system as a stand-alone embedded device. Fuzzy vault scheme is used as the method to bind the crypto key and biometrics. The system processes were implemented as software blocks run on the firmware.
