Virtual reality security authentication method based on panoramic image

Abstract

The invention provides a virtual reality security authentication method based on a panoramic image. The method comprises the following steps: (1) panoramic image display; (2) user control input; (3) user input acquisition: representing user input by using an equipment attitude angle; (4) a user password setting stage: for the password storage problem of the input pixel points, designing a region segmentation algorithm, discretizing the obtained continuous values of the original pixel points, and then storing the discretized region values as a final password; and (5) a user password authentication stage: converting the pixel point information of the password input by the user into region information according to the region segmentation condition, and comparing the region information with the stored final password to realize the authentication of the user identity. Hardware support is not needed, the panoramic picture rich in image information is selected for a user to set a password, input is controlled in an image rotation / interaction mode, and the use experience of the user is improved.

Description

Technical field [0001] The invention belongs to VR terminal privacy protection technology, and specifically relates to a virtual reality security authentication method based on panoramic images. Background technique [0002] With the advent of the 5G era, the high bandwidth and low latency characteristics of the network will greatly improve the experience of Virtual Reality (VR) and Augmented Reality (AR). The current wide application of VR / AR will lead the way The new trend of human-computer interaction. [0003] While the virtual reality system brings a new interactive experience to users, attackers can use various side-channel information such as motion and vision generated during the interaction to guess what the user inputs on the terminal, posing a threat to their private data. The existing types of attacks mainly include terminal sensor-based attacks and computer vision-based attacks. A terminal sensor-based attack is that the attacker records the sensor data during user i...

Problems solved by technology

[0004] At present, defense measures against side-channel attacks on smart terminals include random keyboards, using biological passwords, etc. Random keyboards will greatly increase the time for user input, thereby reducing user experience. Using biological passwords requires hardware support, which is not suitable for virtual reality. system
