Revisiting the accuracy of the biohashing algorithm on fingerprints

Biometric template protection is suitable with the widespread deployment of biometric authentication schemes. Template protection methods are used to ensure the diversity and the security of biometric data, by avoiding storage and misuse of the original template. This study provides an evaluation of the accuracy performance of biometric template protection methods, by revisiting experiments on the biohashing algorithm on fingerprints. It is shown how and why experimental results can be completely falsified with only five random bits.
