Eye sight-based password inputting method and hardware device thereof

Abstract

The invention relates to an eye sight-based password inputting method and a hardware device thereof. The hardware device comprises a shooting unit, a display unit and a processing unit. The eye sight-based password inputting method includes the steps of subjecting the shooting unit to shooting a facial image to form an integral numerical image, determining a target area containing eyes of the user by using Adaboosts to perform a traversal to the integral numerical image and a cascade detection, determining positions of pupil centers of the left and the right eyes and inner eye corner points in the target area, and determining specific positions of sight focuses on the display unit according to geometrical relationship to achieve password inputting. Compared with the prior art, the eye sight-based password inputting method is safer, more rapid and convenient, higher in inputting accuracy, simplified in the required hardware device and lower in cost.

Description

technical field [0001] The invention relates to a pattern recognition technology and an image processing technology, in particular to a method and a hardware device for calculating the focus of eye sight to realize password input. Background technique [0002] With the development of science and technology, the technology of stealing passwords is also constantly improving, which poses a serious security threat to the traditional physical keyboard password input method. However, at present, the traditional physical keyboard password input method still occupies the mainstream position. For example, ATM machines that can be seen everywhere still use the nine-square physical keyboard to input passwords, which is less secure. Therefore, there is an urgent need for a novel password input method that has high security and can be popularized on a large scale. [0003] The eyes are the windows of the human soul, and the transmission of information through the eyes is in line with th...

However, this method also needs to set infrared light sources at the two bottom corners of the screen and three different positions such as the upper left corner to determine the current point of view where the pupils of the eyes of the person are looking, which not only increases the hardware equipment for password input, Moreover, when setting the infrared light source at a specific position, it is necessary to ensure that the position of the infrared light source is correct, which is conducive to the calculation of the current viewpoint position of the eye pupil of the personnel, which will complicate the hardware configuration requirements
