Computational Intelligence Techniques for Biometric Recognition: A Review

Abstract

World is changing and growing very fast, especially in terms of technological advancement. Efficient, secure, & reliable authentication systems are needed to society by these technological advancements. Biometrics provides a means for these needs. Biometric authentication systems are comparatively more fast and efficient. In fact they are more secure & difficult to forge. But as there is nothing called complete in this world exists; similarly biometric systems also suffer many problems. This paper examines some of biometric systems with their merits and demerits. So many physiological and behavioral traits have element of uniqueness and by using them so many biometric systems been developed for environment specific needs and financial investments. There exists a number of commercial applications whose needs are so specific that a uniform and integrated biometric system is not feasible. For eg. Requirements of an attendance monitoring system at a project site are very different than KYC requirements for a financial body.
