Different rights are assigned according to the role of the user, such as the moderator, speaker, listener, etc., or their hierarchy in the organization. Rights allocation may be automatic, based on predefined rules; or may be manual, set by the meeting organizer or administrator. Once the rights are assigned, it is necessary to record the rights level for each user. This information will be used to control the user's operation and access rights in the meeting. The operational permissions define which actions the user can perform in the meeting, such as speaking, sharing screens, text chat, voting, etc. The user is restricted or allowed to perform a specific operation according to the authority information of the user.

And matching the user with the roles in the role library according to the user information such as the positions, departments, responsibilities and the like of the user. For example, a department manager may be matched to a premium speaker or conference moderator role. Meeting access rights factors these factors determine whether a user can view or access particular content in a meeting, such as agenda, files, videos, etc. Conference operation rights factors these factors determine what operations a user can perform in a conference, such as speaking, sharing a screen, editing a document, etc., each role and rights factor is assigned a unique label. The labels are used for rapidly identifying and distributing authorities, the identifier can automatically identify and distribute authorities according to authority labels of the roles, the conference authority identifier is used for carrying out authority identification on each conference participation role, and corresponding access and operation authorities are automatically given according to the labels of the roles and preset authority rules. And mapping the judged role authority information with the specific conference participants. Ensuring that each party can obtain the correct set of rights according to its role. Once the mapping is complete, a detailed list is generated containing all the principals and their corresponding rights.

Different rights level labels are assigned to the content according to its sensitivity and importance. The permission levels may include public, confidential, internal only, etc. And combining the content attribute tag with the authority level tag to create a hierarchical directory structure for the conference subject content. The directory structure reflects the classification and authority level of the content, so that the organization of the content is clearer, and the subsequent access control according to the authority is convenient. And matching the conference access rights of the multiple participants with the rights class labels in the conference subject content directory structure. Based on the matching results, a conference subject content directory tab set is generated for each participant, which reflects the portion of content that the participant has access to. And constructing a catalog branch according to the content authority level label information, distributing the conference attribute content label according to the content authority level label information, and filling the structural content of the catalog branch. And mapping with the original conference theme content by using the generated conference theme content directory label set. In this way, the content blocks that each participant can access according to its rights can be accurately obtained.
Further, in the step S3, encrypting the contents of the plurality of conference access blocks to the plurality of conference participants, including:
s35: respectively carrying out multidimensional encryption analysis on the contents of the plurality of conference access blocks to obtain encryption coefficients of the contents of the plurality of conference blocks;

Specifically, the content of a plurality of meeting access blocks is subjected to deep security analysis, wherein the security analysis comprises a plurality of dimensions such as encryption strength, encryption speed, data size and the like. Based on the analysis result, the most suitable encryption coefficient is determined for each conference access block content. And generating a unique conference key through a security mechanism of the multi-terminal conference interaction cloud platform. This key will be used to encrypt and decrypt conference content. A unique key is generated for each meeting. This key is used to encrypt and decrypt conference content. The generation of the key should ensure randomness and complexity to increase the difficulty of cracking. And combining the encryption coefficients, and configuring the most suitable encryption algorithm for each conference access block content. These algorithms will ensure security during data transmission. And encrypting the contents of the plurality of conference access blocks by using the conference key and the configured encryption algorithm. The encrypted content is called conference encrypted access block content, which cannot be easily decrypted even if intercepted during transmission. To ensure that the encrypted conference content can be transmitted safely, a safe transmission channel is established. The security and the integrity of the data in the transmission process can be ensured by using security protocols such as SSL/TLS and the like. Ensuring the integrity and confidentiality of data transmission. The multiple conference encrypted access block content is transmitted to each conference participant over this secure channel.
Further, the step S35 of obtaining a plurality of encryption coefficients of the conference block contents includes:

In particular, the conference content attributes include the type of content, such as text, image, video, etc., size, sensitivity, etc. The content rights level reflects the confidentiality or importance of the content, such as public, confidential, highly confidential, etc. The reception necessity indicates the importance level or the demand level of the content to the conference participants. And comprehensively evaluating the contents of the multiple conference access blocks based on the conference transmission encryption attribute information. The evaluation includes a plurality of dimensions such as encryption strength requirements, the impact of encryption on performance, the replaceability of the content, etc. And (3) obtaining a comprehensive transmission attribute evaluation value for each conference access block content by taking into consideration multiple dimensions. And constructing a three-dimensional encryption evaluation coordinate system by taking the conference content attribute, the content authority level and the receiving necessity as coordinate axes. This coordinate system provides an intuitive framework for visualizing the encryption requirements of different conference block contents. And mapping the transmission attribute evaluation values of the plurality of conference blocks into a constructed coordinate system. The location of each conference block content in the coordinate system represents a multidimensional feature of its encryption requirements. Based on these locations, encryption coefficients for each conference block content may be determined. For example, for content with sensitive content attributes, high authority levels and strong necessity of reception, a higher encryption coefficient may be allocated to ensure security during transmission thereof.
Further, the determining the plurality of conference block content encryption coefficients includes:
Mapping the conference block transmission attribute evaluation values into the conference transmission encryption evaluation coordinate system to generate a plurality of block transmission encryption evaluation vectors;

Specifically, a plurality of conference block transmission attribute evaluation values are mapped into a conference transmission encryption evaluation coordinate system. The evaluation value of each conference block forms a point in the coordinate system, and a directed line segment pointing to the point from the origin of the coordinate system is a block transmission encryption evaluation vector. And carrying out weight distribution assignment on conference transmission encryption attribute information, conference content attribute, content authority level and receiving necessity according to actual requirements and security policies. These weights reflect the importance of the respective attributes in determining the encryption coefficients. For example, the content rights level may be considered more important than the necessity of reception and therefore may be given a higher weight. And carrying out weighted correction on the generated multiple block transmission encryption assessment vectors by using the determined transmission encryption attribute weight distribution factors. The weight of each attribute is considered in the correction process, so that the determination of the encryption coefficient is more in line with the actual demand and the safety consideration. For each modified block transport encryption assessment vector, its modulus, i.e. the length of the vector, is calculated. This modulus reflects the combined encryption requirement of the conference block content taking into account all relevant factors and is therefore determined as the encryption coefficient of the block content.
Further, the transmitting the plurality of conference encrypted access block contents to the plurality of conference participants based on the data transmission channel in S38 includes:
Performing network security evaluation on the data transmission channel to obtain a channel transmission security evaluation coefficient, and generating a transmission identity authentication instruction when the channel transmission security evaluation coefficient reaches a preset transmission security coefficient threshold;

And traversing the conference trusted identity authentication list based on the transmission identity authentication instruction to obtain information transmission identity authentication information, and transmitting the contents of the plurality of conference encryption access blocks to the plurality of conference participants based on the data transmission channel if the information transmission identity authentication information is matched.
Specifically, the data transmission channel is subjected to comprehensive network security evaluation, and the capability of resisting various network attacks such as man-in-the-middle attack, data interception and the like is checked. And obtaining a channel transmission safety evaluation coefficient according to the evaluation result, wherein the channel transmission safety evaluation coefficient reflects the safety level of the channel. When the channel transmission safety evaluation coefficient reaches or exceeds a preset transmission safety coefficient threshold value, the safety of the channel is proved to meet the requirement, and a transmission identity authentication instruction is generated at the moment. This instruction is used in the subsequent authentication process to ensure that only authenticated entities can transmit data through the channel. And acquiring an identity authentication list containing all the trusted conference participants through the multi-terminal conference interaction cloud platform. This list is used to verify the identity of the entity attempting to receive data over the data transmission channel. Based on the transmission identity authentication instruction, traversing the trusted conference identity authentication list, and carrying out identity authentication on each conference participant attempting to receive data. If the information transfer identity verification information of a certain party matches the information in the list, indicating that the party is trusted, data may be received via the data transfer channel. Once authentication is successful, the contents of the plurality of conference encrypted access blocks are securely transmitted to the participant via the data transmission channel.
