Question 66
1. Iris scanning
2. Retinal scanning
3. Voice recognition
Select the correct answer using the code given below.
AOptions
BSolution
Biometric identification involves using unique biological characteristics or behavioral traits to verify a person's identity. In addition to fingerprint scanning, several other advanced biometric methods are commonly employed:
- Iris scanning: This highly accurate method analyzes the complex and unique patterns in the colored ring of the eye (iris).
- Retinal scanning: This technique maps the unique pattern of blood vessels at the back of the eye (retina), offering another very secure form of identification. It is distinct from iris scanning.
- Voice recognition: This is a behavioral biometric method that identifies individuals based on the unique characteristics of their voice, including pitch, tone, and speech patterns.
All three listed options (iris scanning, retinal scanning, and voice recognition) are well-established and widely used technologies for biometric identification, along with fingerprint scanning.
