Fusion of the biometrics information can occur at different stages of a recognition system. These were adopted after assessment of several different kinds of biometrics including retinal scan. Robert Schwartz was a nationally renowned scientist in the field of biometrics and DNA research. Example applications include dermatoglyphics and soft biometrics. Data privacy is the main concern when it comes to storing biometrics data in companies. There are also numerous countries applying biometrics for voter registration and similar electoral purposes. One advantage of passwords over biometrics is that they can be re-issued.
