Unlocking method and device for touch screen equipment

Abstract

The invention discloses an unlocking method and device for touch screen equipment. The unlocking method comprises the following steps: detecting a press operation on a screen, and determining the press area and the press duration; reading screen lock encrypted data, which is a press parameter set and stored in an encryption process; and unlocking in the event of judging that the current press area and the current press duration respectively accord with the press area and the press duration in the screen lock encrypted data, wherein the encryption process comprises the steps of detecting the press operation on the screen and determining the press parameter including the press area and the press duration. By means of the invention, screen locking and unlocking can be realized at relatively low cost; and the security of the equipment is increased.

Description

technical field [0001] The present application relates to the technical field of smart touch screen devices, in particular to a method and device for unlocking a touch screen device. Background technique [0002] In today's work and life, devices with data processing capabilities, such as computers, mobile phones, handheld computers, tablet computers, etc., have been widely used. Especially portable data processing devices such as mobile phones, palmtop computers, tablet computers, etc. have become an indispensable tool for people to carry with them. [0003] As the amount of information stored in data processing equipment increases, the ensuing issue of privacy protection becomes more and more important. Especially mobile phones, which are not only a communication tool, but also store a lot of personal information. Once lost or lent to others, there will be a great hidden danger of privacy information leakage. [0004] In the prior art, there is a scheme for protecting pr...

Problems solved by technology

[0007] (1) Fingerprint recognition and unlocking technology requires mobile phones to be equipped with sensors that can recognize fingerprints, and the cost of hardware support is high

[0008] (2) The recognition accuracy of face recognition unlocking technology is not high, and it cannot effectively identify photos and real people. If a malicious user picks up the owner's mobile phone and allows the mobile phone to identify the owner's own photo, it can also be unlocked. greater safety hazard

[0009] (3) The password and graphic password unlocking methods are simple and obvious, and are easy to be peeped and remembered by interested people, so there are also major security risks
