Graphical-based user authentication schemes for mobile devices
Huge amount of personal information is stored in the mobile devices now. This requires high-qualified security system in order to provide data confidentiality, if the device is lost or stolen. The main part of such system is an authentication module, and there are several methods used to solve this problem. However, traditional schemes, based on usage of text passwords, are not suitable for mobile devices because of their drawbacks. The main drawbacks are bad memorability and inconvenience for the user, if the device does not have a hardware keyboard. In this case Graphical Passwords (GP) can become a good alternative, because of better memorability, ease of input on a touchscreen, and even higher security level.
Despite the presence of some good enough GP schemes, there is no persuasive method to compare them. While the field investigation, which is expensive, subjective and difficult to repeat, is the only way used to evaluate the usability level, common technique to assess the level of security does not exist at all. And the main goal of the project is to propose novel automated and theoretical methods to evaluate the security level of different GP schemes widely used in mobile devices.
