A More Secure Position Based Graphical Password Authentication

摘要

We are proposing a new pass-point graphical password authentication by using a simple virtual environment. Our virtual environment is influenced by a social networking site's game. In this system, user interacts with the virtual environment and user can generate sequence of interactions according to his/her choice which will gather by a background process. This process decides whether the user is authenticated user or a not, depending on which the system allows or denies accessing the resources. There are many existing authentication schemes are based on a simple pas-point mechanism, most of them are unsuccessful due to the shoulder surfing attacks. The proposed scheme seems sometime similar to the pass-point techniques but it is very much different with respect to the authentication process.
