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. Biometric identification involves identifying a person based on their unique physiological or behavioral characteristics. 2. Fingerprint scanning is a widely used biometric method. 3. Statement 1: Iris scanning analyzes the unique patterns in the colored part of the eye (iris). It is a highly accurate and widely used method for biometric identification. Correct. 4. Statement 2: Retinal scanning analyzes the unique pattern of blood vessels at the back of the eye (retina). It is also a highly accurate biometric technique, though perhaps less common than iris scanning in consumer applications. Correct. 5. Statement 3: Voice recognition analyzes the unique characteristics of a person's voice (pitch, tone, frequency). It falls under behavioral biometrics and can be used for identification or verification. Correct. Therefore, in addition to fingerprint scanning, iris scanning, retinal scanning, and voice recognition can all be used for biometric identification.
