Analysis of SOF(Strength of Function) and vulnerability on Fingerprint Authentication System


Analysis of SOF on Fingerprint authentication systems is different from other security products using password mechanism for identification and authentication. Fingerprint authentication systems use fingerprint recognition algorithm as probabilistic or permutational mechanism for identification and authentication, therefore the different method have to be adopted for analysing SOF. The terms of FAR/FRR could be represented for analysing SOF in Fingerprint authentication systems, so it will be introduced how FAR/FRR is calculated using fingerprint Database which has various characteristic and quality.
It is known that fingerprint authentication systems have their own vulnerabilities. Vulnerabilities using fake fingerprints are most known to the public. Vulnerabilities using fake fingerprints usually take place in input sensors. So it will be introduced that analysing of vulnerability using fake fingerprints like silicone or gelatin.
