Abstract
In search of new methods of protection, developers are increasingly turning their attention to the biometric system. Biometric systems recognize people based on their anatomical features (fingerprint, facial image, drawing the lines palm, iris, voice) or behavioral characteristics (signature, gait). Because these features are physically associated with the user biometric recognition as a reliable mechanism to witness that only those who have the necessary powers, could get into the building, access to a computer system, or cross the border state. Biometric systems also have unique advantages - they do not allow the perfect to renounce the transaction and provide an opportunity to determine when an individual uses several certificates (eg, passports) in different names. Thus, with competent implementation in the respective applications, biometric systems provide a high level of security
