摘要：This paper deals with an add-on for biometric security systems, especially for the fingerprint recognition technology. This added part of such systems is the liveness detection. Our method is based on detection of optical characteristics of the finger surface (skin). The main idea is to detect the movements of papillary lines, but some another optical information could be extracted, what is outlined at the end.
