The industry and academia pay more attention to how to improve the user experience and content generation in the virtual environment, such as improving visual resolution and tactile reproduction, etc., but often ignore the information security issues in the VR environment. For example, user identity authentication, device security issues, application software vulnerabilities, etc. VR devices are just like smart devices. Users can enter the virtual environment by wearing a VR helmet. If there is no security authentication process, anyone who gets the device can enter the virtual space. It is difficult to guarantee user privacy and information confidentiality.

The current mainstream user authentication methods are knowledge-based authentication, such as passwords, gestures, etc., and physiological authentication, such as gait, face recognition, etc. George et al. transplanted the traditional password input method (digits and gestures) into the VR environment, and proved through user experiments that the traditional password input method can maintain a certain degree of security and ease of use. However, the method of using gesture input during the user authentication process is easily captured by external sensors, which leads to the leakage of passwords and brings great security risks. In addition, Shen et al. proposed a new user authentication method, using the inertial sensor that comes with the VR helmet to obtain the user's gait data, and then authenticate the user's identity. However, this method cannot be applied to mobile VR devices, especially in a moving scene, the data of the inertial sensor will be affected by the moving scene, and user authentication cannot be performed accurately. It can be seen that the existing methods have shortcomings and cannot meet the security and accuracy requirements of user authentication at the same time. Therefore, it is necessary to research new methods that can effectively and safely realize user authentication.

Example 1

This embodiment discloses a non-contact user security authentication method based on a mobile VR device, as shown in Figure 1, the steps are as follows:

S1. The user initiates a password setting request to the mobile VR device.

S2. Initial password verification: the mobile VR device receives a password setting request, and outputs multiple optional picture blocks in the VR environment. At this time, the interface is an initial password verification interface, as shown in FIG. 2 . These picture blocks are obtained by dividing a picture, and some of the picture blocks are the default initial password feature blocks of the mobile VR device. Here, the initial password of the mobile VR device is public, and the central block of the default picture of the mobile VR device is the characteristic block of the initial password.

Based on the mobile VR device, the user selects the initial password feature block in the picture block by visual gazing to complete the initial password verification, as shown in Figure 3.

Here, the mobile VR device can specifically detect the user's visual gaze point through an internal sensor, and output a selection indication icon corresponding to the visual gaze point in the VR environment, and the selection indication icon is located on the option that the user gazes at. The mobile VR device records the duration of visual fixation. When the duration of visual fixation reaches the preset duration (such as 3s, which can be adjusted according to the actual situation), it is determined that the user has selected the picture block. The mobile VR device can change the color/brightness of the selected picture block (for example, the center block is set to black in Figure 3), so that the user can know which dynamic numbers have been selected.

S3. Digital password setting:

S31. After the initial password authentication is completed, the mobile VR device first outputs the user identification input interface in the VR environment, and the user inputs his own user identification (that is, the user ID) in the user identification input interface through the mobile VR device. Here, the virtual keyboard can be used. Interact with gestures/visual gaze for input;

S32. The mobile VR device stores the user ID, and then outputs a digital password length setting interface in the VR environment. The digital password length setting interface has a plurality of optional dynamic numbers in a moving state, and these dynamic numbers follow a fixed moving direction and Trajectory movement (Arabic numerals 0 to 9 as shown in Figure 4 form a circle and rotate circularly according to the direction of rotation); based on the mobile VR device, the user selects dynamic numbers through visual gazing, so as to realize the input of the length of the digital password.

S33. The mobile VR device receives and stores the set digital password length, and then outputs a digital password setting interface in the VR environment, and the digital password setting interface also has a plurality of dynamic numbers moving according to a fixed moving direction and trajectory (as shown in Figure 5 The Arabic numerals 0 to 9 shown are in a circle and rotate according to the direction of rotation);

S34. Based on the mobile VR device, the user selects a number of dynamic numbers sequentially according to the length of the digital password through visual gazing, that is, completes the input of the dynamic numbers;

The dynamic numbers received by the mobile VR device can be displayed in the corresponding display box on the digital password setting interface at the same time. When the number of dynamic numbers reaches the length of the digital password, the mobile VR device will then form the user ID with the dynamic numbers selected by the user Corresponding digital password, and store it.

For example, if the user wants to set a digital password 05123 consisting of 5 numbers, first select the dynamic number 5 as the digital password length in the digital password length setting interface, specifically: look at the dynamic number 5 through the mobile VR device, and follow the 5 Move, when the gaze duration reaches the preset duration, 5 is selected, as shown in Figure 4. The direction of the arrow in Fig. 4 is the moving direction. Then select 0, 5, 1, 2, and 3 in sequence in the digital password setting interface, as shown in Figure 5, the user has selected 0 and 5, and needs to continue to select 1, 2, and 3.

The mobile VR device can change the color/brightness of the selected dynamic numbers when the visual fixation time reaches the preset duration and the dynamic numbers are selected, so that the user can know which dynamic numbers have been selected.

S4. Picture password setting: After the digital password is set, the mobile VR device outputs multiple optional picture blocks in the VR environment. At this time, the interface is the picture password setting interface, as shown in FIG. 6 .

Based on the mobile VR device, the user selects several picture blocks through visual gazing. Here, the mobile VR device can change the color/brightness of the selected picture blocks when the visual fixation time reaches the preset time and the picture blocks are selected, so that the user can know which picture blocks have been selected. For example, if the user selects the picture block in the upper right corner of FIG. 7 as the picture password, the corresponding picture block in the upper right corner turns black, as shown in FIG. 7 .

The mobile VR device generates a corresponding picture password based on the picture block selected by the user, and stores it. The digital password corresponding to the user ID and the picture password together form the user password corresponding to the user ID.

Here, the multiple picture blocks output by the mobile VR device are obtained by dividing one picture, which may be the same as the picture to which the picture block in step S2 belongs, or may be different from the picture to which the picture block in step S2 belongs. In addition, in other embodiments, the picture blocks can also be set to move cyclically according to a fixed moving direction and trajectory, just like the dynamic numbers.

If the user wants to set a picture password with a new picture, the user can send a new picture to the mobile VR device through a terminal device (such as a smart phone, tablet, computer) before setting the picture password, or the mobile VR device can directly network to obtain a new picture. This makes it possible for the mobile VR device to generate multiple picture blocks based on the new picture when the user sets the picture password.

If the user does not first send a new picture to the mobile VR device or the mobile VR device does not obtain a new picture through the Internet first, then when the user sets the picture password, the picture block generated by the mobile VR device is the same as the picture block in step S2, as shown in Figure 2 and Figure 2. 6.
