Mix up ‘Unique’ with ‘Secret’ and confuse ‘Identification’ with ‘Authentication’?
Biometrics follows “unique” features of individuals’ bodies and behaviors. It means that it could be well used when deployed for identification of individuals who may be conscious or unconscious, alive or dead. Due respect could be paid to biometrics in this sphere.
Being “unique” is different from being “secret”, however. It would be a misuse of biometrics if deployed for security of the identity authentication of individuals.
Confusing “Identification” with “Authentication”, we would be building a sandcastle in which people are trapped in a nefarious false sense of security. However gigantic and grandiose it may look, the sandcastle could melt away altogether when we have a heavy storm.
