Fake Fingers in Fingerprint Recognition: Glycerin Supersedes Gelatin

Fingerprint Recognition currently widespreads in numerous identity verification applications such as electronic ID cards, travel documents, access control and time attendance. Security issues with the condition of use of the authentication device is a major concern in such applications. Recent publication in this field shows the lack of aliveness detection mechanism in fingerprint sensors technology, especially by using Gelatin-made fake fingers. Different material may be used to mold and reproduce exact copy of a fingerprint with its detailed shape and extended characteristics (e.g. minutiae points location). In this paper we will present a state-of-the-art of fake finger materials and disclose the power of a, let's say, brand new material in this field: Glycerin
