Numerical password via graphical input — An authentication system on embedded platform

Graphical systems have been in use in the embedded world for user authentication. Image based systems use image, area or pattern selection process. This paper presents a novel method that employ image recognition at its first level and a modified PassPoint logic with randomization using LFSR at its next level to provide a well secured password authentication system. The proposed real-time authentication scheme for embedded system aims at reducing the password storage space against a similar implementation on embedded platform.
