Embodiment Construction

[0018] The following uses independently designed equipment as an example to further illustrate the present invention.

[0019] 1. Lighting Design Module

[0020] The key to this module is to detect and find the appropriate light intensity. Specifically, it is considered that pupil changes are most sensitive to light intensity compared to other factors. The goal of the present invention is to design appropriate light intensity and obtain rich biometric information that can effectively identify people in as short an authentication time as possible.

[0021] 2. Pupil data acquisition module

[0022] This module is how to obtain the change information of the pupil size. The biological information of the pupil (contraction and dilation of the pupil) is spontaneously generated by the designed light stimulation, and these signals can be obtained by an ordinary camera placed on the VR glasses. As the authentication process continues, the pupil size will continue to change. In ord...

Abstract

The invention discloses a head-mounted device authentication method based on pupil light reflection, the pupil light reflection is a biological reflection, and the intensity of light falling on the retina is controlled by enlarging or reducing the pupil, so the human is helped to adapt to different brightness or darkness. The dynamic response is controlled by a sympathetic nervous system and a parasympathetic nervous system, both of which are part of the autonomic nervous system (ANS). According to the invention, by comparing the correlation between the data captured by the camera carried on the head-mounted device, whether the comparison device is a legal user is verified, and once the user authentication fails, the device cannot be used, and vice versa.

Description

technical field [0001] The present invention relates to a head-mounted device authentication method based on pupillary light reflection (PLR), which is applied in the technical field of head-mounted devices: VR and smart glasses. By comparing the correlation between the pupil change data, the involved devices can be judged Whether it belongs to its legitimate user, so as to achieve the purpose of successfully authenticating the VR device for use by its legitimate user. Background technique [0002] As we all know, smart head-mounted or smart helmet devices, including smart glasses, such as augmented reality (AR: Vuzix) and virtual reality (VR: Oculus), have gained enormous popularity in recent years. Mobile devices, especially the popular VR headsets, have brought a new form of entertainment to everyone's life with added convenience. However, with the emergence of VR headsets, many security and privacy issues have also emerged. Users can store their personal information in...
