Types of Biometrics
Biometrics can be broadly classified into two types:
- Physical Biometrics
- Behavioural Biometrics
Physical Biometrics
Physical Biometrics identifies an individual based on physical characteristics like fingerprints, facial scans, DNA etc.
Physical Biometrics are further classified into:
- Facial recognition
- Fingerprint recognition
- DNA matching
- Retina scan
- Ear authentication
Facial recognition
Facial recognition is used to identify an individual by scanning the face of the person. Most smartphones have this feature.
Fingerprint recognition
Fingerprint recognition is one of the oldest recognition methods. Each individual has a unique fingerprint; therefore, this method is highly used. Fingerprint recognition is used in smartphones and computers to unlock the device.
DNA matching
DNA contains genetic information. Thus DNA matching is used to identify whether a man is the biological father of another person. DNA matching is also used to trace criminals.
Retina scan
In this scan, the blind spot of the eye and the blood vessels on the surface of the retina is observed.
Ear authentication
We use the external ear of an individual to distinguish him in this authentication. The human ear shape is unique, and thus this scan is quite accurate.
Behavioural Biometrics
In this identification method, we see the characteristics of the person’s behaviour.
Behavioural Biometrics is further divided into:
- Voice recognition
- Keystroke method
- Signature recognition
Voice recognition
Voice recognition is used in intelligent buildings. Voice recognition identifies an individual based on voice frequency and other voice characteristics.
Keystroke method
The keystroke dynamics identifies an individual based on the keystrokes they make on the keyboard.
Signature recognition
Signature recognition has been used since long ago for identification. We use signatures in banks, property papers etc., for authentication.
FAQs
1. What is Biometrics?
Biometrics is used to distinguish an individual from others by using physical characteristics like fingerprints, retina scans etc.
2. What are the uses of Biometrics?
Biometrics are used for unlocking phones and laptops. They are used at the airport and law enforcement to identify an individual.
3. What are the two main types of Biometrics?
The two main types of Biometrics are physical and behavioural Biometrics.
4. What are behavioural Biometrics?
In behavioural Biometrics, we identify the person based on the characteristics of the person’s behaviour. Signature recognition is an example of behavioural Biometrics where we identify an individual based on the person's signature.
5. What are the examples of physical Biometrics?
Examples of physical Biometrics are DNA matching, retina scan etc.
