Abstract

This article aims to present the importance of authentication for E-mail ID through improved CAPTCHA based method.The structure of the CAPTCHA has to be reorganized to suit the user requirements to facilitate the authentication for E-mail ID. CAPTCHA is achieved by rearrangement of alphabets randomly on the buttons and it is very easy to frustrate by simple keyloggers. The motive of improving E-mail authentication is done by incorporating two factor visual authentication mechanisms. It is targeted to CAPTCHA based human interaction with sophisticated user friendly protocol. All the intermediate interaction is visualized by the user with better CAPTCHA code. It provides only one time (or) one session valid authentication through color grid rating method. This two layer authentication promises more secure in accessing any secure information based portal.
