Abstract

The invention discloses a touch screen unlocking method and system based on a mobile terminal. The method includes the steps that N touch points sequentially arranged and the sliding time range Ti between every two adjacent touch points are set on a touch screen unlocking interface of the mobile terminal in advance and stored, wherein both the N and the i are natural numbers larger than 1, and the i is smaller than or equal to the N; an unlocking command of a user is detected, the touch point coordinates of touching a touch screen by the user and the time difference of touching the adjacent touch points by the user are obtained, and whether the preset touch point coordinate sequence and the sliding time range of touching the adjacent touch points are met or not is judged, if the conditions are met, unlocking is successful, and if not, a hint that unlocking is valid is given out. According to the touch screen unlocking method and system, whether the mobile terminal touch screen is unlocked by judging whether the sequence of the touch points and the touch time difference of the adjacent touch points are consistent with the preset value or not, the touch points can move according to the conditions as well, unlocking safety is improved, and convenience is brought to users.

Description

technical field

[0001] The present invention relates to the technical field of mobile terminals, in particular to a method and system for unlocking a touch screen based on a mobile terminal. Background technique

[0002] With the development of mobile communications and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones has become more and more popular, and mobile phones have become an indispensable communication tool in people's lives.

[0003] At present, mobile terminals, especially smart mobile terminals, generally adopt the unlocking technology based on the touch screen, but the existing unlocking technology scheme is too simple, usually 9 numbers, and unlocking is done by drawing the unlocking track, but this unlocking method is relatively fixed because the unlocking track is relatively fixed. It is easy to be cracked by others, so that anyone can easily unlock the mobile terminal, which reduces the securi...
