Biometric Security

Will there be a "biometric-of-choice", i.e. a technology dominating all biometric systems? The answer is most likely no. The reason is that no biometric trait is fully universal, permanent and unique at the same time. Today's most accurate technologies are based on characteristics of eyes and fingers that are highly unique and permanent in structure, but not completely universal. At the same time, none of the fully universal characteristics (e.g. faces and DNA) are sufficiently unique to distinguish between monozygotic twins. Faces are even highly variant with time.
