Challenges and Trends by Biometric Authentication

Authentication is a key parameter used to talk about an attribute that a real entity require to be true.There are several ways to make authentication more efficient, and biometrics is one of them.Since thelast decade, biometric technology has been widely adopted and accepted everywhere to identify a person's identity.Also the presented technique overcomes the limitations associated with the traditional authentication process, such as database problems including passwords and IDs to authenticate a person.This article provides a comprehensive survey of existing biometric methods, their uses and their limitations in real time.This also provides an incentive to adapt biometrics to current situations.In addition, it also tries to talk about the technical and security aspects of biometric systems.
