Benefits and issues of biometric technologies. Are biometrics worth using?

Biometric technologies have been used for a long time, but each type of biometrics has its own benefits and flaws. In this paper we will discuss the current types of biometrics and biometric systems, their benefits and issues. We will also present the results of several experiments with such biometric technologies as facial and voice recognition that will show how effective they are and if it is worth using them in the everyday life scenarios.
