Dynamic Biometric Signature - an Effective Alternative for Electronic Authentication

The use of dynamic biometric methods for the authentication of people provides significantly greater security than the use of the static ones. The variance of individual dynamic properties of a person, which protects biometric methods against attacks, can be the weak point of these methods at the same time.This paper summarizes the results of a long-term research, which shows that a DBS demonstrates practically absolute resistance to forging and that the stability of signatures provided by test subjects in various situations is high. Factors such as alcohol and stress have no influence on signature stability, either. The results of the experiments showed that the handwritten signature obtained through long practice and the consolidation of the dynamic stereotype, is so automated and stored so deep in the human brain, that its involuntary performance also allows other processes to take place in the cerebral cortex. The dynamic stereotype is composed of psychological, anatomical and motor characteristics of each person. It was also proven to be true that the use of different devices did not have a major impact on the stability of signatures, which is of importance in the case of a blanket deployment.The carried out experiments conclusively showed that the aspects that could have an impact on the stability of a signature did not manifest themselves in such a way that we could not trust these methods even used on commercially available devices. In the conclusion of the paper, the possible directions of research are suggested

DYNAMIC BIOMETRIC SIGNATURE AS AN EFFICIENT TOOL FOR INTERNAL CORPORATE COMMUNICATION

Cílem práce je podat ucelenou informaci o možnostech autentizace, kombinace autentizačních faktorů a začlenění této problematiky do podnikové komunikace. Práce se zaměřuje na tuto problematiku a specifikuje možnosti získání autentizačních informací, dále analyzuje metody autentizace, identifikace a autorizace. Zkoumaná je využitelnost biometrických technologií, princip funkčnosti, příklady jejich použití, jejich vliv, výhody a nevýhody, které přinášejí. Přirozený, snadno dostupný, a tedy vhodný nástroj pro efektivní a bezpečnou komunikaci je autentizace zahrnující dynamický biometrický podpis. Problematika technologie dynamického biometrického podpisu a jeho implementace jsou zkoumány z komplexního hlediska včetně provedených experimentů. Z výzkumu vyplývá, že dynamický biometrický podpis dokáže sloužit jako metoda podporující bezpečnou podnikovou komunikaci a zredukovat autentizační rizika ve společnostech i pro jednotlivce.The aim of this thesis is to provide comprehensive information on the possibilities of authentication, combination of authentication factors and the integration of this issue into corporate communication. The work focuses on this issue and specifies the possibilities for obtaining authentication information, analyses the authentication methods, identification and authorization. It examines the applicability of biometric technologies, the principle of their functionality, examples of their use, their impact, the advantages and disadvantages they bring. A natural, easy-to-use, convenient tool for effective and secure communication is authentication including the dynamic biometric signature. The issues of the dynamic biometric signature technology and its implementation are examined from a comprehensive perspective involving experiments. The research proved that the dynamic biometric signature can serve as a method for supporting secure corporate communication and reduce authentication risks in companies and for individuals.
