Currently the computer and internet become important part of everyone's life. The large amount of important data can be transferred as well as stored by the various applications. The user friendly applications are provided for easy handling. The various schemes are invented for securing such applications. Textual passwords as well as graphical passwords are used for authentication. But these authentication schemes are vulnerable to various types of attacks.
