|
|
|
What are different types of Biometrics?
|
|
| |
Biometrics can be broadly divided into 2 main categories:
- Physical Biometrics - based on physical characteristics (face, fingerprints, hand geometry, iris, retinal, vein, voice, etc)
- Behavioral Biometrics - based on behaviorial characteristics (speaker recognition, signature, keystroke, etc)
|
|
Which is the most accurate biometrics?
|
|
| |
|
Iris recognition is considered to be most accurate of all biometrics.
|
|
What is difference between Identification and Verification?
|
|
| |
- Identification - determining a person's identity. It answers the question - who is this person?
- Verification - confirming a person's identity.
If a person says "Hi, I am Tom", the verification system's job is to verify if this person is Tom or not. If the person is not Tom, then the system does not go on to determine the person's identity. Instead, the system just returns saying "Sorry, this person is not Tom."
