Abstract

Fingerprint is the most famous biometric that is mostly used in various authentication systems. Fingerprint of human being exhibit certain details marked on it, categorized it as minutiae, which can be used as a unique identity of a person if recognize it in a well manner. Large volume of fingerprint are collected and stored every day in a varied range of applications. In this context, the compression of these data may become commanding under certain circumstances due to the large amounts of data involved. This paper present the characteristics of biometric features of fingerprint image, talk over the necessity of fingerprint compression and present abstract review on different existing fingerprint compression standards such as DCT based JPEG, DWT based JPEG-2000, WSQ, etc. and the proposed method is given which is implementation of fingerprint image compression by using the method of sparse representation.
