Fingerprint template protection techniques — A survey and analysis

Biometric security threat is an issue of dynamic attack against weakness in a biometric system. While biometrics may enhance security detached situations, in the same way as some other security system, it has vulnerabilities and it is vulnerable to threats. They are defenceless to outer vulnerabilities of biometric systems so that their shortcomings can be discovered and valuable counter measures against predictable attacks can be created. The undeniably prominent utilization of biometrics for security purposes has incited new enthusiasm toward inquiring about and investigating systems for attacking biometric systems. In this survey, we have taken different categories of template protection methods and stated the evolution, usage, merits and demerits of each category along with comparison of the metrics GAR, FAR, FRR and EER in tabular form. This paper gives the ideology to find out the pitfalls in the existing algorithm and suggests for research development in hybrid methodologies to achieve better results.
