Which biometric identification method uses an image of the eye for verification?

• A. Fingerprint scan
• B. Face recognition
• C. Eye/retina scan
• D. Voice recognition

Answer: (C)

The use of eye or retina scanning as a biometric identification method relies on capturing an image of the unique patterns and characteristics of the eye, specifically the retina or the iris. This method is highly secure and reliable because the patterns in the eye are intricate, unique to each individual, and do not change over time.

In contrast, fingerprint scanning focuses on the uniqueness of an individual’s fingerprints, while face recognition examines facial features and their spatial relationships. Voice recognition analyzes vocal characteristics but is more susceptible to changes due to health or environmental factors. Therefore, the eye/retina scan stands out as the method specifically designed for taking images of the eye for verification purposes.
