Parts of the body used in biometrics and their recognition pattern

priyadharshan

can you give the details about the parts of the body used in biometrics and their recognition pattern.i.e. in what way do it differ from other human's part?

The ones I'm aware of are:

1. fingerprint
2. hand geometry
3. face
4. iris
5. voice (not technically "part of the body")

Compared to alternatives, these are relatively accessible, and in most contexts are socially acceptable to access for security purposes.
