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.

Legal aspects of forensic dactyloscopy and its perspectives
Andrašková, Tímea ; Dvořák, Marek (advisor) ; Šelleng, Dalibor (referee)
Legal aspects of forensic dactyloscopy and its perspectives Abstract The main theme of the diploma thesis is forensic dactyloscopy. It is an identification method that is nowadays an essential part of forensic science. This method is based on three fundamental principles of fingerprinting concerning the relative constancy, non-removability, and individuality of papillary lines. The key to the success of the method is the use of absolutely unique markers. Due to this, dactyloscopy can be used in detection and investigation of crimes. The thesis is divided into four thematic parts. In the first one, attention is paid to the history of dactyloscopy and the personalities who have connected it with forensic science. Chapter two focuses on defining the substance of forensic dactyloscopy from the scientific point of view. The object of this section is to elucidate the reasons why dactyloscopy can be considered a reliable and fundamentally infallible identification method. The third chapter converts scientific knowledge into forensic practice. The purpose is to explain simple mechanism of the formation of fingerprint traces and to introduce the techniques by which a fingerprint can be made suitable for laboratory examination. The chapter discusses not only traditional methods of searching for and securing...

Concept and nature of dactyloscopy (fingerprinting)
Šišková, Jitka ; Štourač, Petr (advisor) ; Musil, Jan (referee)
91 15. SUMMARY Concept and nature of fingerprinting The purpose of my thesis is to completely examine the issue of dactyloscopy and introduce this forensic method, both the theoretical and practical parts. It deals with the historical development of dactyloscopy, the legislation in the Czech Republic, finger- print impression, capture, constancy, detection and comparison. For greater clarity and orientation, the thesis is composed of several parts - each dealing with different aspects. It is also supplemented with pictures that help to imagine a particular thing. Chapter One contains an introduction which gives a general view of dactylosco- py as a forensic method. Chapter Two deals with the historical development and important personalities of dactyloscopy. It explores the origins of knowledge of fingerprint patterns in ancient times and also focuses on the pioneers of dactyloscopy. The chapter is subdivided into three parts. Part One deals with Jan Evangelista Purkyně who first described and classi- fied the basic patterns of friction ridges on distal phalanges. Part Two mentions the world personalities of dactyloscopy (for example Francis Galton, Juan Vucetich, Henry Faulds). The development of dactyloscopy in the Czech Republic is included in Part Three. Chapter Three discusses the concept, the object,...

Concept and nature of fingerprinting
Šetelíková, Alice ; Štourač, Petr (advisor) ; Konrád, Zdeněk (referee)
Concept and nature of dactyloscopy The aim of the thesis is to provide a comprehensive view on the issue of dactyloscopy. Especially, to introduce readers about dactyloscopy and institutes related to this method. The thesis is systematically divided into several chapters. The thesis is complemented by visual and textual appendices for the better and easier understanding of the various institutes. The introduction contains basic information about dactyloscopy and the outline of what the thesis will contain. Chapter One deals with the subject, concept and importance of the dactyloscopy. Chapter Two is divided into two parts. The first subchapter concerns the historical development of forensic dactyloscopy in the world. First of all, there are described the beginnings of knowledge of fingerprints and then personalities and their influence on the development of the dactyloscopy. As an example of these significant personalities, William James Herschel, Henry Faulds or Juan Vucetich can be cited. The second subchapter is focused on the development of the dactyloscopy in the territory of the Czech countries. In particular, the place is given for Jan Evangelista Purkyně well known as a pioneer in the area of papilary ridges. Because it was him who as the first described and classified the papilary ridges....

Police Identification of Persons in Czechoslovakia between 1918 and 1938
Tůma, Lukáš ; Himl, Pavel (advisor) ; Rutar, Václav (referee)
This thesis is focused on police techniques of identification of persons used in Czechoslovakia between 1918 and 1938. The goal of this thesis was to show, how the police identification of persons should look like, in other words which techniques were used by criminologists, how they described them, which accomplishments and negatives they saw in them, who had to be identified and for which purpose. To answer all these questions I deal with political and administrative context of Czechoslovakia, police structure in Czechoslovakia between 1918 and 1938 and development of criminology, "bertillonage" and documents of identification (especially passports) in the first part of the text, where I mainly use secondary literature. Then I focus on analysis of three main techniques of identification used between 1918 and 1938, namely dactyloscopy, graphology and photography. In this part of the thesis, I use criminology manuals, published in the twenties and thirties. Finally, I work with the fourth technique of identification of persons, namely the description of persons, where I mainly use forms, which are in the criminology manuals. Thus, heart of this work is based on normative documents from the twenties and thirties wrote by criminalists or graphologists. Keywords Police, criminology, identification,...
