A method of protecting the right attendees in an online meeting

Abstract

This invention discloses a method for protecting the correct participants in online meetings. Before entering the meeting, the current participant undergoes identity authentication, obtaining their facial feature value and binding it to the current ID of the logged-in user. Upon entering the meeting, the identity ID of the authenticated online meeting software is verified a second time. During the meeting, the facial features of the current video and the authenticated ID are compared in real time. Non-facial areas are set as background images. When a non-participant enters the video area without obscuring the participant's face, they become part of the background; when they obscure the participant's face, the entire screen is automatically set as the background image. This ensures that the current participant in the online meeting is the correct one. After the correct participant is authenticated, the background image is either turned on or off, and is encrypted using the SM4 encryption algorithm for background protection. This protects the background of non-participants from being cracked by malicious attackers who could obtain the true background data.

Description

Technical Field

[0001] This invention relates to the field of online conferencing technology, and in particular to a method for protecting the correct participants in an online meeting. Background Technology

[0002] Online meetings, also known as web conferencing or remote collaborative work, enable users to share data among multiple users in different locations via the internet. They can be used for various purposes such as online sales, remote customer support, IT technical support, remote training, and online marketing activities.

[0003] In existing online conferencing solutions, participants connect to an internet-based conferencing server via personal computers or mobile phones. These personal computers or mobile phones then become the conferencing terminals. These terminals are aggregated through the conferencing server, allowing participants to easily discuss and exchange information about various projects online. Throughout the online meeting, the cloud-based conferencing server is responsible for authenticating the identities of each participant, processing meeting documents, and facilitating data exchange. During the online meeting, the built-in webcam of the personal computer or mobile phone is used to capture the participant's image and background data. Users can turn their webcams on and off at any time and set background images in the online conferencing software to mask their surroundings.

[0004] However, when one or more other people appear in the video and their cameras are not turned off in time, they may appear in the video, potentially interfering with the normal conduct of the online meeting or failing to protect the personal privacy of the current participants, including personal environmental information and information about those around them. The current solution has the following problems:

[0005] 1. Background settings can only block environmental information, such as being in a coffee shop or at home, but cannot block moving people or animals.

[0006] 2. The background content lacks data protection. Malicious attackers can steal communication data and then analyze the graphics and images to obtain the specific content in the background. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method for protecting the correct participants in online meetings, effectively solving the problems that existing technologies cannot block people irrelevant to the meeting and that background content is not protected.

[0008] The technical solution includes the following steps:

[0009] Step 1: Before entering the meeting, verify the identity of the current participant;

[0010] Step two: After successful authentication, obtain the facial feature value of the current person and bind it with the current ID of the logged-in person in the online meeting;

[0011] Step 3: Upon entering the meeting, the identity ID of the online conferencing software, which has undergone identity verification, will be confirmed a second time.

[0012] Step four: During the meeting, the facial features of the current video and the identity verification ID will be compared in real time to determine if there is any interference from personnel;

[0013] Step 5: Based on Step 4, the meeting proceeds normally without any interference from other personnel. Non-face areas are set as background images. When non-meeting personnel enter the video area, they will become the background if they do not block the faces of the participants. If they do block the faces of the participants, the entire screen will be automatically set as the background image.

[0014] Preferably, the background image is any image selected by the user;

[0015] The background image is turned on or off after the correct participant has been authenticated;

[0016] The background image is encrypted using the SM4 encryption algorithm for background protection.

[0017] Preferably, the step of encrypting the background image data for background protection using the SM4 encryption algorithm is as follows:

[0018] S1, generates the SM4 encryption key;

[0019] S2: After successful registration and authentication of meeting participants, the meeting system generates a key, binds it to the identity ID, and stores it in the database;

[0020] S3, when calling the key, will find the key by the identity ID and load it into the server memory for real-time encryption;

[0021] S4. When the meeting ends, the meeting service will unbind this key from the database and delete the key.

[0022] S5: When the encryption keys in the database are used up, a new batch of keys will be requested and stored in the server.

[0023] The beneficial effects of this invention are as follows: 1. Before entering the meeting, the current participant is authenticated once, and their facial feature value is obtained and bound to the current ID of the logged-in user of the online meeting. Upon entering the meeting, the identity ID of the online meeting software, which has been authenticated, is confirmed a second time. During the meeting, the facial features of the current video and the authenticated ID are compared in real time, and non-facial areas are set as background images. When a non-participant enters the video area and does not block the face of the person in the video, they will become the background; when the face of the participant is blocked, the entire screen will be automatically set as the background image, thus ensuring that the current participant in the online meeting is the correct participant.

[0024] 2. After the correct participant is authenticated, the background image is turned on or off. It is encrypted using the SM4 encryption algorithm for background protection. After the encryption key is used up, a new batch of keys will be applied for and stored in the server to protect the background of non-participants from being cracked by malicious attackers and obtaining the real background data.

[0026] Figure 2 This is a flowchart of the background protection process. Detailed Implementation

[0027] For the purposes of this invention, the foregoing and other technical contents, features and effects are described in conjunction with the appendix below. Figures 1 to 2 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0028] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] A method for protecting the correct participants in an online meeting includes the following steps: Step 1, before entering the meeting, the user logs in and performs an identity verification (e.g., facial recognition) on the current participant.

[0030] Step two: After successful authentication, obtain the facial feature value of the current person and bind it with the current ID of the logged-in person in the online meeting;

[0031] Step 3: Upon entering the meeting, the identity ID of the online conferencing software, which has undergone identity verification, will be confirmed a second time.

[0032] Step four: During the meeting, the facial features of the current video and the identity verification ID will be compared in real time to determine if there is any interference from personnel;

[0033] Step 5: Based on Step 4, the meeting proceeds normally without any interference. Non-face areas are set as background images. When non-meeting personnel enter the video area, they become background if they do not block the faces of the participants. When they do block the faces of the participants, the entire screen is automatically set as the background image. For example, if the original background image is a virtual study background with a row of bookshelves behind the participants, only the study background will be visible, and no one will appear. The background will block everyone who appears in front of the camera.

[0034] Example 2: Based on Example 1, the background image is any image selected by the user;

[0035] The background image is turned on or off after the correct participant has been authenticated;

[0036] The background image is encrypted using the SM4 encryption algorithm to protect the background, ensuring that even if malicious actors intercept the data in the video, they cannot obtain the real data behind the background.

[0037] Example 3: Based on Example 2, the step of encrypting the background image data for background protection using the SM4 encryption algorithm is as follows:

[0038] S1 generates the SM4 encryption key, which can be generated by the hardware encryption machine or by the cloud encryption machine service;

[0039] S2: After successful registration and authentication of meeting participants, the meeting system generates a key, binds it to the identity ID, and stores it in the database;

[0040] S3, when calling the key, will find the key by the identity ID and load it into the server memory for real-time encryption;

[0041] S4. When the meeting ends, the meeting service will unbind this key from the database and delete the key.

[0042] S5: When the encryption keys in the database are used up, a new batch of keys will be requested and stored in the server. This ensures that the protection key for a meeting is used only once, minimizing the risk of key leakage or misuse.

[0043] In practical use, before entering the meeting, the user logs in and undergoes identity authentication (e.g., facial recognition). After successful authentication, the facial feature value of the current person is obtained and bound to the current ID of the logged-in user in the online meeting. Upon entering the meeting, the identity ID of the online meeting software, which has been authenticated, is confirmed a second time. During the meeting, the facial features of the current video and the authenticated ID are compared in real time to determine if there is any interference. If there is no interference, the meeting proceeds normally, and non-facial areas are set as background images. When non-meeting personnel enter the video area and do not block the video's face, they become part of the background. When they obscure the face of a participant, the entire screen is automatically set as the background image. The background image is encrypted using the SM4 encryption algorithm for background protection, ensuring that even if malicious individuals intercept the data in the video, they cannot obtain the real data behind the background.
