This is our second biometric traits where we will take iris as our physical trait for recognizing the authorized user. The iris is the annular region of the eye bounded by the pupil and the sclera (white of the eye) on either side. Each iris is believed to be distinctive and, like fingerprints, even the irises of identical twins are expected to be different. It is extremely difficult to surgically tamper the texture of the iris.
The image of the iris will be Gray scaled and the gray scaled image will be processed with a process called smoothing. The edge of the iris image will be retrieved and that image will be compared with the image stored in the database.
