Abstract:
This diploma thesis focuses on multibiometric systems, specifically on biometric fusion. The thesis describes eye biometrics, i.e. recognition based on retina and iris. The key part consists of design and implementation specification of a biometric system based on retina and iris recognition.

Abstract:
V posledním desetiletí došlo ke zvýšení zájmu o užití 3D dat k biometrické identifikaci osob. Možná vůbec největší výzkum proběhl v oblasti 3D rozpoznávání podle obličeje, přičemž je v současné době dostupných vícero komerčních zařízení. V oblastni rozpoznávání podle 3D geometrie ruky byl v minulých letech proveden určitý výzkum jehož výsledkem však nebylo žádné komerční zařízení. Nezávisle na tomto výzkumu se v posledních letech velmi rozšířil trh s cenově dostupnými 3D sensory, což potenciálně umožňuje jejich nasazení v mnoha typech biometrických systémů. Hlavním cílem této práce je vytvořit

Abstract:
Security is very important in present day life. In this highly-interconnected world, most of our daily activities are computer based, and the data transactions are protected by passwords. These passwords identify various entities such as bank accounts, mobile phones, etc. People might reuse the same password, or passwords related to an individual that can lead to attacks. Indeed, remembering several passwords can become a tedious task. Biometrics is a science that measures an individual’s physical characteristics in a unique way. Thus, biometrics serves as a method to replace the cumbersome us

Abstract:
Biometric based security systems are becoming an integral part of many security agencies and organisations. These systems have a number of applications ranging from national security, law enforcement, the identification of people, particularly for building access control, the identification of suspects by the police, driver’s licences and many other spheres. However, the main challenge is to ensure the integrity of digital content under different intentional and non-intentional distortions; along with the robustness and security of the digital content. This thesis focuses on improving the secu

Abstract:
The main topic of the thesis is creation of formulas for the amount of information entropy in biometric characteristics of iris and retina. This field of science in biometrics named above is unstudied yet, so the thesis tries to initiate research in this direction. The thesis also discusses the historical context of security and identification fields according to biometric characteristics of a human being with an overlap for potential usage in biometrics of iris and retina. The Daugman’s algorithm for converting iris image into the binary code which can be used as a cryptographic key is

Abstract:
The idea of merging biometrics technology with cryptography brought interesting possibilities in enhancing the security and privacy of biometrics systems. Conventional systems generally require large databases, which represent a security risk and raise privacy concerns. Biometric encryption is a method devised to hide biometric features along with a cryptographic key, which could remove the need for such biometric databases. The Fuzzy Vault scheme is one of the promising candidates for biometric encryption. This thesis analyzes the scheme and attempts to provide solutions to problems impeding

Abstract:
Biometric authentication systems are used to guide the system security for many years in the computer world and make the user's identification easier and more convenient. Meanwhile, the systems encounter lots of challenges, attacks and threats, privacy protection and system management requirements, which affect the user's acceptance. Differing from the commonly used solutions, in this thesis the approach is to modify the system to meet these requirements, which results in a distributed architecture which can be composed in real time, and resolves the above challenges in one solution.

Approved for public release; distribution is unlimited.<br>This study evaluates an inexpensive personal computer access control system that relies on biometric keystroke typing dynamics technology, BioPassword Model 2100 (BioPassword). Enrollment time, verification time, false rejection error rate, false acceptance error rate, and user acceptance were evaluated for this system. The results show that BioPassword provides multilayer security through the inclusion of privilege control, audit functions, passwords, and verification of a personal behavioral characteristic, the rate and variation of

Abstract:
Biometric systems are being increasingly used, from daily entertainment to critical applications such as security access and identity management. It is known that biometric systems should meet the stringent requirement of low error rate. In addition, for critical applications, the security and privacy issues of biometric systems are required to be concerned. Otherwise, severe consequence such as the unauthorized access (security) or the exposure of identity-related information (privacy) can be caused. Therefore, it is imperative to study the vulnerability to potential attacks and identify the
