The use of biometrics in IT

Biometrics is increasingly applied in IT (biometric methods today generally use computer technology), mostly used to authenticate users. The aim of this thesis is to describe and compare two selected biometric methods. These methods are fingerprints and scanning of human face. The contribution of this work is to provide information on biometric identification methods, their advantages and disadvantages, and deployment options. If an organization decides to strengthen their security systems with introduction of biometric identification / verification systems, they can find information about these systems, types of sensing devices and their advantages and disadvantages. This work will provide an answer WHY introdukce and use these systems to persons who are responsible for the security policy. The first part after the introduction contains basic concepts in the field of biometric identification, followed by a general overview of the stages of biometric processing (from data collection to their storage), the main areas of use of biometric identification (corporate sphere, security of persons and property, law enforcement agencies and the courts, banking and e-commerce, travel and tourism, and telecommunications), measuring performance in biometrics. Then follow the main chapters of work consisting of two chosen methods of biometric identification (fingerprints and face) and their summaries in the form of mapping advantages and disadvantages
