Problems solved by technology

[0004] Aiming at the shortcomings of traditional unlocking gesture operations that are easy to be peeped and repeated by others, and general fingerprint recognition technology cannot identify living bodies, this invention utilizes the differences in each person's palm size, finger length, distance between fingers when making a fist in the natural air, and action mode when fingers are bent. Establish a record of the gesture characteristics of the authorized operator, and use this as the basis for identification

Embodiment Construction

[0011] Combine below figure 1 and figure 2 The specific composition of the technical solution of the present invention is introduced.

[0012] Such as figure 1 As shown, the technical solution includes a touch screen (1001) with multi-touch function (two or more points), an unlocking program (1002) and a gesture feature database (1003). Among them, the touch screen (1001) is responsible for collecting the multi-touch information of the operator, and the unlocking program (1002) receives the information collected by the touch screen (1001) to perform calculations, calculates gesture features, and compares it with the gesture feature database (1003). If the characteristics of the unlocking signal are issued, otherwise the unlocking signal is not issued.

[0013] Such as figure 2 As shown, the logic of the unlocking program in the technical solution of the present invention is:

[0014] 1. The initial system is in a locked state, and the unlocking program is waiting for in...

Abstract

The invention relates to a finger slide identification unlocking method for a touch screen and relates to a technique which allows an operator to be identified according to one multi-point slide performed by the operator on an electronic screen before unlocking. A system using the technique comprises a touch screen, an unlocking program and a gesture feature database. The unlocking program tracks slide features of multiple fingers of an operator on the touch screen, compares the calculated features with the gesture feature database, unlocks when the calculated features conform to gesture features of an authorized operator, and remains locking if not.

Description

Technical field [0001] The present invention is a technical scheme in which the operator performs finger touch and slide on the electronic touch screen, and the unlocking program identifies and unlocks the operator according to the touch input. The release of the lock protection status (prevention of misoperation, prevention of unauthorized operation, device standby shutdown, lock and other unusable and protected status) of electronic devices with touch screens and electronic files in these devices. Background technique [0002] As an input device component, electronic touch screens with multi-touch functions have been widely used in desktop computers, mobile phones, tablet computers, electronic locks and other electronic devices that require manual input. The release of these desktop computers, mobile phones, tablet computers, electronic devices and electronic files in them needs to accept manual input to identify the operator. The main method is to realize the sliding or ...
