Abstract

The invention discloses a password input system. The password input system comprises a screen, a camera, a metronome module, an image recognition module, a code conversion module, a comparison and judgement module and a storage module, wherein the metronome module is connected with the screen; the image recognition module is connected with the camera and the metronome module; the code conversion module is connected with the image recognition module; the comparison and judgement module is connected with the code conversion module; the storage module is connected with the comparison and judgement module; and the storage module pre-stores a preset code corresponding to a correct rhythm password set by a user. According to the password input system, the image recognition module recognizes a light-shade alternative pattern formed by shielding the camera according to rhythms, so that password input is carried out. The invention furthermore discloses a password input method. According to thepassword input system and method, password input can be carried out through forming light-shade alternative specific patterns by shielding the camera by fingers according to rhythms; and the passwordinput system and method are strong in safety, simple and practical.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a password input system and method. Background technique [0002] With the development of society, in today's mobile Internet era, more and more personal mobile terminals emerge one after another, such as smart phones, tablet computers, MID (Mobile Internet Device, mobile Internet equipment) and so on.
