Method and system for unlocking touch screen of mobile terminal

Abstract

The invention discloses a method and system for unlocking a touch screen of a mobile terminal. The method includes the steps that (A) the mobile terminal receives a user operation instruction, the screen is lightened, an unlocking interface is displayed, and a prestored image containing an unlocking pattern is called randomly and displayed on the unlocking interface; (B) a pattern drawing operation instruction of a user on the unlocking interface is received, a pattern drawn by the user is obtained, and similarity comparison is carried out on the pattern drawn by the user and the displayed unlocking pattern to obtain a shape similarity value; (C) the obtained shape similarity value is compared with a preset threshold value, and if the shape similarity value is larger than or equal to the threshold value, the touch screen is unlocked. The unlocking method is achieved in a mode that the user draws patterns displayed randomly, the unlocking processes are different, freshness and interestingness of unlocking are increased on the premise of simple unlocking operation, the problem that precision of a sensor is reduced due to the fact that an unlocking area is fixed in the existing unlocking technology is avoided at the same time, the service life of the touch screen is prolonged, and product experience of the user is improved.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and system for unlocking a touch screen of a mobile terminal. Background technique [0002] The existing smartphone unlocking schemes are basically slider unlocking or Jiugongge unlocking. This kind of unlocking scheme is currently lacking in innovation. Performing the same unlocking action every time will cause users to feel repetitive, make users lose interest in unlocking, and reduce The user's product experience; and the existing unlocking operations capture the touch time in a fixed area of ​​the touch screen. Long-term operation will cause greater wear and tear on the touch screen in this area and reduce the accuracy of the sensor. However, if the mobile terminal uses a too complex unlocking scheme, it will be cumbersome and cumbersome , It is not easy to operate, and it becomes a stumbling block in some emergency situations. [0003] Therefore, the prior a...
