Vulnerability of any given security system is an important aspect that needs to be carefully analyzed during design phase. When dealing with biometric systems, one important source of such vulnerability that needs to be especially considered is its tendency to deception by spoofs. Since a high enough quality spoof can become indistinguishable from the original biometric characteristic by human eye, we may need additional methods of spoof recognition. We investigate several approaches used as an antispoofing method, with emphasis on approaches utilizing the liveness detection (antispoofing).
