Fingerprint Liveness Recognition
Lodrová, Dana ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This document deals with presentation of nowadays software and hardware methods used for fingerprint recognition with focus on liveness testing and thereafter it deals with description of my solution. In order to describe results obtained from study of technical literature, we discuss important terminology of biometric systems at first and further main principles of fingerprint sensors used in practice are shown. From overviewed methods of liveness detection we underline one method based on perspiration (researched by BioSAL laboratory) and one spectroscopic method researched by Lumidigm Corporation. The study of liveness testing methods inspired me to creation of new type fingerprint sensor which has built-in livennes testing method based on two characteristic properties of living human tisue. In order to test this sensor, we discuss nowadays sensor deception method. It follows from their analysis, that newly designed sensor should be theoretically resistant to each of them.

Biometrical Liveness Detection - Mechanical Characteristics
Zaklová, Kateřina ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
Main focus of this thesis is the detection of liveliness of the finger by the means of mechanical methods. Theoretical part of the thesis describes biometric systems, their reliability metrics, various kinds of sensors and methods of liveness detection. Two methods are covered in detail - liveness detection by odor and liveness detection by temperature. The thesis also illustrates implementation of the application for liveness detection by temperature and evaluates range of experiments carried out during the research.
