Question

In biometric identification systems, at the beginning, it was soon apparent that truly positive identification could only be based on physical attributes of a person. This raised the necessity of answering 2 questions :

Options

Awhat was the sex of a person and his age
Bwhat part of body to be used and how to accomplish identification that is viable
Cwhat was the age of a person and his income level
Dwhat was the tone of the voice of a person and his habits

How the community answered

B

C

D
8% (2)

Explanation

Once it was established that positive identification must rely on physical attributes, two practical questions emerged: (1) which part of the body provides the most uniquely identifiable and stable attributes, and (2) what technology and methodology can make that identification process reliable and practical for real-world use. Options A, C, and D refer to demographic characteristics (sex, age, income, voice tone, habits) which are not unique enough per individual and are not the engineering or design questions biometric pioneers needed to answer.
