Time-Series Detection of Perspiration as a Liveness Test in Fingerprint Devices.

The article focuses on the use of time-series detection of perspiration as a liveness test in fingerprint scanners. Fingerprint scanners may be susceptible to spoofing using artificial materials or in dismembered fingers. An anti-spoofing method based on liveness detection has been developed for use in fingerprint scanners. The method quantifies a specific temporal perspiration pattern present in fingerprints acquired from live claimants.
