Biometric data refers to unique physical identifiers like fingerprints, retina scans, and digital signatures that can be used to identify individuals. Retina scans in particular analyze the unique patterns of a person's retinal blood vessels for authentication and identification purposes. While retina scans are highly reliable and accurate for identifying people, they can be affected by eye conditions and require expensive equipment and close proximity during the scan.

1. Biometric Data:
Biometric data refers to records used to uniquely identify people, such as: fingerprints,
Retina scan (eye scan), and Digital signature. Biometrics is the name given to the various
methods of capturing, storing, and utilizing this data. Biometric data is used for the
identification of individuals for the purposes of controlling access, and various applications
for preventing crime.
Retina Scan:
A retinal scan is a biometric technique that uses the unique patterns on a
person's retina blood vessels. Retinal scanners are typically used for authentication and
identification purposes.
Advantages:
 Extremely Low occurrence of false Data.
 Highly reliable because no two people have the same retinal pattern.
 Speedy results: Identity is verified very quickly.
Disadvantages:
 Measurement accuracy can be affected by a disease such as cataracts.
 Measurement accuracy can also be affected by severe astigmatism.
 It is apparent to some people that scanning procedure is persistent.
 Not very user friendly.
 Subject being scanned must be close to the camera optics.
 High equipment cost.
