Abstract : Text-based passwords are not necessarily as secure as they appear because the protocols required for a secure password are typically ignored for a more user-friendly one. In this paper, we propose a new sketch-based password system that uses biometric data and provides exceptional tradeoff between security and usability. By extending a shape recognition algorithm called Simple K-Space (SKS), a system that is capable of being both secure and robust is developed. In theory and experimentation, new insights into the SKS philosophy are provided, including uniqueness of the model and tolerance of the framework. This system is compared with a state-of-the-art graphical password system using Dynamic Time Warping (DTW) and found to achieve comparable performance without using any biometrics. The addition of biometrics substantially increased the level of performance, reducing the equal error rate (EER) by more than 12%
