Of the following biometric methods, which is the least reliable for security purposes?

Retina scan
Voice analysis
Fingerprint scan
Hand analysis (geometry scan)

Explanation

Answer: B - The least reliable biometric method is voice analysis because a recording of the person’s actual voice can be used to authenticate.

Key Takeaway: Imitating a person’s voice sufficiently well to fool voice recognition software is highly unlikely, but a recording contains all of the factors needed to trick the software. Retina, fingerprint, and hand analysis all have unique characteristics to prevent replication.
