Abstract
It has been long recognized that no silver bullet exists to achieve both security and memorability. With the addition of usability requirements, the task of designing authentication schemes for mobile devices becomes more challenging. We propose a Multi-dimensionAl Pabword Scheme (MAPS) for mobile authentication. MAPS fuses information from multiple dimensions to form a pabword. This fusion enlarges the pabword space, improves memorability, and enhances usability by reducing the number of gestures needed for authentication. Based on the idea of MAPS, we implement a Cheb-based MAPS (CMAPS) for Android systems. Our user studies show that CMAPS can achieve high recall rates while exceeding the security strength of current mobile authentication schemes and exceeding the requirements of banking.
