Voiced 3D Password Authentication

摘要

In today’s world, security is important aspect in day to day life .So, everyone used various ways for security purpose. People use passwords for their security .Generally, everyone uses textual password. Textual password is combination of alphabets and numbers. People keep textual password as name of their favorite things, actors or actress, dish and meaningful word from dictionary. But the person who is very close to that person can easily guess the password. Graphical password is advanced version of password. Graphical passwords have received considerable attention lately as Potential alternatives to text-based passwords. Graphical password is composed of images, parts of images, or sketches. These passwords are very easy to use and remember. To overcome the Drawbacks of previously existing authentication technique. We present A new improved authentication technique , This authentication Scheme is called as “ voiced 3D password”. The voiced 3D password is multi-password & multi-factor authentication system as it uses a different authentication techniques such As textual password , sound password, graphical password , biometrical password . Most important part of 3d password scheme is inclusion of 3D virtual environment. We proposed that user first can write him/her user name and textual password and then the program provide a studio for choosing the specific sound , then passed to 3D virtual environment . Shoulder-suffering attack is still can affect the schema of 3D password , so we add the Voiced 3D password to reduce that affect . Keywords:3D password , textual password , graphical password , biometric password , voiced password, Quick hull algorithms, convex hull algorithm .
