Fingerprint recognition is a popular security feature in the newer generation of smartphones and is a well-known biometric technology. Since Microsoft introducing iris recognition feature in its smartphones, there were comparisons between these two biometric traits. We will be discussing both these biometric technologies, their capabilities and security features.

Iris and fingerprint recognition both have higher accuracy, reliability, and simplicity as compared to other biometric traits. These attributes make iris and fingerprint recognition perform better and a particularly promising security solution in today's society. The process starts by capturing the images of iris and fingerprint which are then pre-processed to remove any noise effects. The distinguishing features are then extracted and matched to find similarity between both the feature sets. The matching scores that are generated from the individual recognizers are given to the decision module which decides if a person is genuine or an impostor.

What are the steps involved in fingerprint recognition?Fingerprint recognition is a proven technique to verify the identity of individuals and hence it is one of the most widely used biometric technologies. A fingerprint is basically composed of ridges and valleys that are on the surface of the finger. In fingerprint recognition, there are three major steps that are applied to acquired images using the minutiae matching approach.
What are the steps involved in iris recognition?

Prior to proceeding with any of the steps mentioned above, it is important to acquire an image of the iris that is rich in texture because all subsequent steps will depend upon the quality of the iris image. A 3CCD camera is used to capture the image of the iris under a controlled lab environment. This captured image is then passed to a localization module that detects the iris portion from the rest of the image.
