Problems solved by technology

The fingerprint recognition method is highly secure, but it still requires finger touch
Eyeball unlock and gesture unlock have the same security risks
[0005] The existing unlocking methods cannot achieve a balance between convenience and security, and it is difficult to balance user experience and user privacy protection

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] see figure 1 , the present invention comprises the following steps:

[0035] 1) The unlocking grid pattern randomly appears on the screen of the mobile phone. The user sets the trajectory by himself, scans the unlocking grid nodes according to the set trajectory, and collects real-time parameters while the user scans; the real-time parameters include: Face recognition parameters, user eye movement characteristic parameters, and hand shaking, movement, and acceleration parameters when people scan The movement trajectory of the eye center, the built-in timer to obtain the time of human eye saccade, the relative position relationship between the pixel and the human eye center and the timer data to obtain the parameters of saccade acceleration and saccade angle; use the built-in gyroscope, linear accelerometer, magnetic field of the mobile phone The sens...

Abstract

The invention relates to an intelligent equipment unlocking method based on a human eye motion feature. The method comprises the following steps: acquiring a human face identification parameter, a user eye motion feature parameter as well as hand shake, movement and acceleration parameters during glancing of a user; extracting a user feature value and storing the user feature value; during unlocking, acquiring the human face identification parameter, the user eye motion feature parameter as well as the hand shake, movement and acceleration parameters during glancing of the user; extracting the user feature value; and comparing the user feature value of an unlocking person with the stored feature value, and outputting a signal indicating whether to unlock or not. A mobile phone can be unlocked conveniently and rapidly in an eyeball glancing way. On the other hand, 'shoulder surfing attack' can be prevented by adopting a mechanism of feature parameters, and an illegal user cannot unlock the mobile phone even if an unlocking pattern is obtained, so that the safety is improved. By adopting the unlocking way, the problem of user experience and safety is balanced. The intelligent equipment unlocking method has wide development and popularization prospects.

Description

technical field [0001] The present invention relates to a device unlocking method, in particular to a smart device unlocking method based on human eye movement characteristics. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the popularity of smart phones has gradually increased, and touch-screen phones have been recognized by people. [0003] At present, the unlocking methods of touch-screen mobile phones mainly include slide unlocking, password unlocking and gesture unlocking. The sliding unlock method is simple, but the security is low. Password unlocking requires both hands to participate, and the convenience is low. Gesture unlocking is a security risk, and anyone who knows the unlocking gesture can unlock the phone. [0004] Emerging unlocking methods include fingerprint recognition and eyeball unlocking. The fingerprint identification method is highly secure, but it still requires finge...
