This document discusses research into liveness detection techniques for biometrics. It summarizes several technologies used in fingerprint sensors, such as optical, capacitive, ultrasound and others. It then outlines various liveness detection methods including analyzing perspiration, spectroscopic characteristics, temperature and pressure stimulus, pulsation of pixels, electrical properties, and analyzing pulse and heart activity. The document presents experiments differentiating real fingers from fakes. It also discusses challenges such as skin diseases and environmental factors that affect liveness detection. Overall, the document reviews the state of the art in liveness detection research for biometrics like fingerprints, finger veins, iris, retina and 3D face recognition.
