This paper introduces a new method for detecting fake finger using the fractional Fourier
transform (FrFT). The advantage of this method is to require one fingerprint image. The …

Biometric scanners have become widely popular in providing security to information
technology and entry to otherwise sensitive locations. However, these systems have been …

A contactless fingerprint sensor provides deformation-free, high-quality fingerprint images
and offers users a cleaner and more comfortable measurement environment. Here we …

An effective approach for the detection of real fingerprints based on the Radon transform is
proposed. The results demonstrate that the method well distinguishes false fingers from real …

Absolute security does not exist: given funding, willpower and the proper technology, every
security system can be compromised. However, the objective of the security community …
