In addition to fingerprint scanning, which of the following can be used in the biometric identification of a person?

1. Iris scanning
2. Retinal scanning
3. Voice recognition

Select the correct answer using the code given below.

1. 1 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Explanation

All options are correct

• Biometric identification is the process of recognising or verifying an individual’s identity based on their unique biological or behavioural characteristics.
• Iris scanning and retinal scanning use distinct patterns in the eye, which are highly unique and stable over time. Voice recognition is a behavioural biometric that identifies a person based on vocal characteristics such as pitch, tone, and speech patterns. Thus, all three, iris scanning, retinal scanning, and voice recognition, are valid biometric techniques used for identifying individuals.
