Abstract

Abstract: Because traditional Android mobile phone passcode keypad without anti-peeping function, so we propose a kind of anti-peep code passcode keypad based on hybrid image and fuzzy adaptive visual distance adjustment. First, replace the key bitmaps with hybrid images to solve the problem that password keyboard doesn't have anti-peeping function. Then, the fuzzy logic and adaptive principle are used to solve the user's use problem. Finally, it is found through experiments that the time to refresh 10 hybrid images is between 0.38s and 0.48s, and the blur effect of the image can be automatically adjusted according to the distance. The results show that the anti-peep code keyboard makes up for the problem that the traditional passcode keypad has no anti-peeping function.
