Iris Recognition: The iris is a thin, coloured, round allocation of the eye, located in its stomach. When we lecture to to someone’s eyes as “black”, or “blue”, it is this portion that we are talking of. Just with the biological features of human fingers, the iris of all human is unique.

The characteristics of a fingertip surface – the patterns of the ridges, valleys (Minutiae) and furrows – are analyzed to determine identification. Included in these patterns are the arches, whorls (Spirals and concentric circles) and loops of the fingerprint. Two images are checked for a be of the same mind to ascertain the identity of a person. Apart from enliven thing commonly used in biometric attendance system, it is along with utilized in forensics.
Face Recognition: Visual biometrics analyses the facial features – as soon as the disaffect along amid eyes, the size of the nose and the assume of the cheekbones – using computer applications to authenticate an identity. First, images are taken by a security or valid-time 3D camera, and later evaluated and the measurements recorded in a database. Unless a 3D camera is used, there needs to be allowable lighting for the images. This technique’s most notable application is in appear in enforcement areas.
