Intelligent equipment screen free gesture vector unlocking method

Abstract

The invention discloses an intelligent equipment screen free gesture vector unlocking method comprising the following specific steps: monitoring a user touch motion under a locked screen state; allowing the user to sweep the touch screen so as to form a dynamic locus; forming a vector according to a release point and a start point when the user leaves the screen, and determining whether the user inputted vector sequence is consistent with a preset vector sequence or not; if yes, unlocking the screen so as to enter a normal mode; if the information coupling fails, the intelligent equipment stays in the locking mode. By using the method, the screen can be unlocked by operations on a random position of the screen, thus effectively preventing a repeated unlocking path, effectively preventing screen damages caused by sliding on fixed positions in a long time, and fully preventing stain attacks; in addition, an irregular arrangement combination mode is employed so as to provide higher screen locking safety, and blind operation unlocking is realized; the intelligent equipment screen free gesture vector unlocking method is easy and convenient.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a method for unlocking a smart device screen with free gesture vectors. Background technique [0002] With the development of mobile Internet, the progress of society and the improvement of people's living standards, more and more smart terminal devices, such as smart watches, tablet computers, smart phones, etc., rely on their excellent performance, portability and good user experience , attracting more and more consumers. [0003] At the same time, touch screens are also popularized along with the consumption wave of smart devices. In order to save battery energy and prolong the life of the screen, the touch screen of the smart device will enter the standby lock screen state when it is not operated for a long time. Users need to go through a specific unlock operation to enter the main interface. [0004] There are currently many screen unlocking solutions, which are mainly d...

AI Technical Summary

Problems solved by technology

[0011] The technical problem mainly solved by the present invention is to provide a free gesture vector unlocking method for the screen of a smart device. Aiming at problems such as low security, insufficient convenience, and inability to unlock the screen by blind operation in the prior art, the present invention can be used in Unlocking at any position on the screen can effectively eliminate repeated unlocking paths, has a very low probability of misoperation, and can effectively reduce screen wear and tear caused by long-term sliding at a fixed position

In addition, it fully solves the screen trace problem caused by Jiugongge unlocking and reduces the risk of "smudge attack"
