Sequential graphical password framework for mobile devices

Nowadays, computer systems are very essential for human daily life for its ability to store and retrieve data in a more meaningful way. Thus, the data stored in computer system contains a very critical and important information and therefore, there´s a critical needs to put more effort in handling of such data. Based on the traditional method, the most popular authentication way for computer security is using alphanumeric password. However, this type of authentication method come with few drawbacks. In recent years, many new methods have been developed by researchers to overcome the limitation of the password authentication, and one of the most popular method is known as graphical password, which utilizes picture as password instead of the alphanumeric string. Hence, this paper propose a new graphical password framework and method to be used in mobile-platform. Finally, the experiments results demonstrated the effectiveness of the proposed solution.
