Entity may be a person. If a entity is a person it can authenticate with the help of its traits such as his facial attribute, fingerprinting attribute, retina attribute, palm attribute, signature of a person, password, token attributes etc. There are so many attacks to which these techniques are vulnerable. So, today the security of the authentication system is becoming a burnt issue. Keeping in the view, the importance of the authentication systems, we analyze various authentication techniques in our paper. And try to find out various advantages and disadvantages of various authentication systems. This paper gives the emphasis on the various issues involved in the various authentication techniques. Keywords- Biometrics, Authentication, Knowledge based,Token based, Security etc. I. INTRODUCTION In the present era, many application areas need secure scheme for authentication. .The authentication system has been deployed in various areas in the industry as well as in military and in the e-commerce etc. Traditionally, passwords and ID cards have been used to authentication to systems. However, security can be easily break in these systems when a password is divulged to an unauthorized user or a card is stolen by an impostor; further, simple passwords are easy to guess (by an impostor) and difficult passwords may be hard to recall (by a legitimate user). The emergence of biometrics has addressed the problems that plague traditional verification methods. Biometrics refers to the automatic identification (or verification) of an individual (or a claimed identity) by using certain physiological or behavioral traits associated
