Improving the performance of projection-based cancelable fingerprint template method

Biometrics, especially fingerprint, has been popular to use for authenticating users because it is relatively permanence. This characteristic, however, is a problem because once it is compromised, fingerprint data can not be replaced. The conventional cryptographic algorithm may not be able to protect fingerprint data since the fingerprint scanning result is unstable. This paper improves the performance of the previous projection-based fingerprint protection method by removing the need of the core point and applying further minutiae checking hierarchically. The experimental result which is done in a public database produces the EER of about 1%.
