4-D Authentication Mechanism
Ronak Talati, Shubham Shah · IOSR Journal of Computer Engineering · 2014
Computer technology is reaching new milestones with every passing day but authentication schemes are still weak in their approach.It has now become a child's play for others to filch, hack or fabricate our passwords.Many authentication schemes have been proposed but each has some drawbacks.Hence, the 3D password paradigm has been introduced.The 3D password is a multi-layer, multifactor authentication mechanism.It consists of a 3D virtual environment on which a user has to perform certain actions.The sequence of actions determines the user's 3D password.It combines all existing authentication schemes like textual, graphical and biometrics into a single 3D virtual environment.The 3D virtual environment is easily customizable by the user as per his requirements.This paper presents a study of the 3D password and an approach to strengthen it by way of adding a Fourth dimension, that deals with gesture recognition and time recording, and that would help strengthen the authentication paradigm altogether.Hence we attempt to propose a 4D password as a super class of 3D password.
