CMAPS: A Chess-Based Multi-Facet Password Scheme for Mobile Devices
The main aim of this project is to give high secured Authentication password scheme which user can easily remember.
A secure authentication scheme should have a large password space, i.e., a large number of possible passwords. Obviously the passwords generated by the scheme should also be easy to remember. In this paper, we separate memorability from usability to emphasize the importance of memorability. It has long been recognized that no silver bullet exists to achieve both security and memorability. Obviously with the addition of a usability requirement, the task becomes even more challenging. The alphanumeric password scheme, which has been used for decades for various computer systems, is not suitable for mobile authentication. The scheme generally requires a keyboard for quick input of alphanumeric passwords. It has long been recognized, by both security researchers and human-computer interaction researchers that no silver bullet for authentication exists to achieve security, usability, and memorability.
We propose a Multi-facet Password Scheme (MAPS) for mobile authentication. MAPS fuses information from multiple facets to form a password, allowing MAPS to enlarge the password space and improve memo ability by reducing memory interference, which impairs memory performance according to psychology interference theory. The information fusion in MAPS can increase usability, as fewer input gestures are required for passwords of the same security strength. Based on the idea of MAPS, we implement a Chess-based MAPS (CMAPS) for Android systems. Only two and six gestures are required for CMAPS to generate passwords with better security strength than 4-digit PINs and 8-character alphanumeric passwords, respectively. Our user studies show that CMAPS can achieve high recall rates while exceeding the security strength of standard 8-character alphanumeric passwords used for secure applications.
