THE INFLUENCE OF AMBIENT CHANGES ON THE QUALITY OF BIOMETRIC DATA

Abstract

Biometry is area of special interest of information systems.Biometric authentication of users becomes essential requirement for logging into a service, an app and so on. In a modern society authentication of users i.e. verification of identity becomes everyday need. With increase of users accounts of different systems and apps, the number of passwords that one user needs to remember increases as well. This issue biometry is trying to resolve on global level. Bad photo quality of biometric sample is one of the issues that could jeopardize success of biometric systems. Quality of biometric sample depends of acquisition which is the first phase of authentication proccess. Since the image quality depends on controlled environment condition it will also have effect on biometric system performance.This paper presents possible problems od data acquisition issues of biometric modals that are mostly used.
