Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] figure 1 is an identity authentication method based on gesture features provided by an embodiment of the present invention, such as figure 1 shown, including steps:

[0037] S101. Comparing the gesture currently input by the user on the touch screen with the number of fingers in multiple pre-registered gestures, and / or the total distance moved by the fingers, and / or the gesture input time, so as to obtain a rough similarity.

[0038] Among th...

Abstract

The invention discloses an identity authentication method based on gesture characteristics, and the method is applied to a touch screen device. The method includes the steps that a current input gesture, on a touch screen, of a user is roughly compared with a plurality of gestures input in advance, and therefore rough similarity can be obtained; if the rough similarity requirement is reached, the acceleration, the angle and the distance of the current input gesture at each time slice are calculated, whether the acceleration, the angle and the distance of the current input gesture at each time slice are within the upper limit range and the lower limit range of the acceleration, the angle and the distance of the gestures input in advance at the corresponding time slice respectively or not are judged one by one, and the final similarity is calculated according to the judgment result; if the final similarity reaches a second preset threshold value, it is judged that identity authentication succeeds. The invention further discloses an identity authentication system based on the gesture characteristics. Through the method and system, according to the difference of the stability of the gestures input by the user, different password security grades are given.

Description

technical field [0001] The invention relates to the field of multi-touch technology, in particular to an identity authentication method and system based on gesture features. Background technique [0002] At present, electronic devices such as mobile phones and computers have become indispensable tools in people's daily life. Once a large amount of user data, personal information, fast payment functions, photos, etc. are stored in mobile phones or computers, once lost, the property of users and other personal great influence. Relying on the previous numbers or letters as the password is easy to leak or be cracked, and the password security is not high. [0003] Most of the current applications use gestures to unlock touch screen devices, which usually use the trajectory of the finger as the basis. If the trajectory entered by the user is different from the previously entered trajectory, it will be judged as unlocking failure. If they are consistent, it will be judged as unlo...
