发明名称 CALCULATING A PASSWORD STRENGTH SCORE BASED UPON CHARACTER PROXIMITY AND RELATIVE POSITION UPON AN INPUT DEVICE
摘要 A solution for computing password strength based upon layout positions of input mechanisms of an input device that entered a password. A password including an ordered sequence of at least two characters can be identified. A position of each of the characters of the sequence can be determined relative to a layout of an input device used for password entry. Each position can correspond to an input region (key) of the input device (keyboard). A proximity algorithm can generate a proximately score for the determined positions based upon a pattern produced by the positions given the layout of the input device. A password strength score can be computed based at least in part upon the proximity score.
