Abstract:
Mobile phones are rapidly becoming an important tool to carry out financial transactions besides the normal communication. They are increasingly being used to make payments, access bank accounts and facilitate other commercial transactions. In view of their increased importance there is a compelling need to establish ways to authenticate people on the mobile phones. For the last several decades the popular method of authentication on computers has been text based. Both the username and password are alphanumeric. The textual password scheme though convenient to use suffers from various drawbacks. Alphanumeric passwords are most of the times easy to guess, vulnerable to brute force attacks, prone to shoulder-surfing, and are easily forgotten. With financial transactions at stake, the need of the hour is to have a secure, robust, and usable scheme for authentication. Graphical passwords are one of such schemes that offer a plethora of options and combinations. In this paper we are proposing a scheme which is simple, secure and robust. The proposed graphical password scheme will provide a large password space and at the same time will facilitate memorability. It is suitable to implement on all touch sensitive mobile phones as well as PDAs and Tablet PCs.
