[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0013] Figure 1 It is a schematic diagram of modules provided by an exemplary embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the drawings.

[0015] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can be made. These all belong to the protection scope of the present invention.

[0016] Please refer to Figure 1 , the present invention discloses a content security audit and traceability system based on blockchain. The system includes: User module: Users need to register and log in to the system. When registering, users need to provide personal information such as name, contact information, etc. These information will be saved in a relational database. When logging in, users need to enter the username and password provided during registration, and the system will verify whether these information match. If the match is successful, the user will log in successfully and can upload videos.

[0017] Blockchain module: When the user uploads a video and passes the audit, the system will upload the user information and the audited video information to the blockchain. The process of uploading to the blockchain includes packing the data into a transaction and then sending the transaction to the blockchain network. This process will ensure the security and immutability of the data. At the same time, the blockchain information returned after uploading to the blockchain will be saved in a non-relational database for subsequent traceability queries.

[0018] Traceability module: Based on the blockchain information saved in the non-relational database, the traceability module can perform traceability queries on any video. Users can initiate a traceability request by entering the video code or the on-chain address. The system will query on the blockchain based on this information and return the corresponding on-chain information. This information will include the uploader, audit status, upload time, etc. Among them, the video code is assigned to the user when the user uploads the video and is used to mark the current video to be uploaded. One video corresponds to one video code, and the same user can also upload multiple videos, that is, multiple video codes can be obtained.

[0019] Furthermore, the system provided by the present invention further includes a verification module: To ensure the authenticity and integrity of the data, the system will compare and verify the returned on-chain information with the information in the database. If the two match, it means the data is trustworthy; otherwise, the system will prompt the user that the data may have been tampered with. Database: The database of this system is divided into a relational database and a non-relational database. The relational database is used to store user information and video information, and the non-relational database is used to store the blockchain information of the user information and video information after uploading to the blockchain. This design can facilitate users to query and verify the data.

[0020] The following will further elaborate on the specific process in combination with Figure 1 and the specific working process is as follows:

[0021] Users register and log in through the user module. After logging in, the user selects to upload a video; the user module generates a globally unique video code that increments with the system to identify the video uploaded by the current user. This video code and information related to the video (such as title, description, etc.) are recorded in a relational database for subsequent queries. Then the user uploads the video, triggering the upload process. The user module calculates the hash value of the video and passes it to the blockchain module. The current video enters the queue to be reviewed.

[0022] Reviewers log in to the system and enter the review interface. Reviewers select a video from the queue to be reviewed and review the video, generating detailed review process information, including: Reviewer information: the identity information of the reviewer to ensure the traceability of the reviewer's identity; Review conclusion: the reviewer's review decision indicating whether the video passes the review; Review time: the timestamp recording the review operation for traceability. If the review is passed, the video information enters the queue of passed reviews and more information is generated: Content rating: based on the review conclusion and the nature of the video content, the system generates a content rating for subsequent appropriate management and classification of the video; Publisher information: identifying the user information of the video publisher, including user ID, username, etc., for tracing the source of the video.

[0023] After the review is passed, the review status of the video is updated to "review passed" in the relational database, and the content rating and publisher information are recorded in the relational database together with the video information for subsequent user queries and system management. Metadata of the reviewed video is generated, including the video code, the hash value of the video, the content rating, the publisher information, etc. The blockchain module uses the generated video metadata and review process information to trigger the process of uploading video information to ensure the secure storage of this information on the blockchain.

[0024] The blockchain module retrieves the reviewed video information from the queue of passed reviews. The blockchain module constructs a transaction using the video metadata and review process information, which also includes information such as the uploader, reviewer, review process information, content rating, publisher, etc. A smart contract is used to perform the operation of uploading video information, and the smart contract stipulates the data structure and the logic of uploading. The transaction of video information is packaged into a block, and the consensus algorithm ensures the consistency of the block. Nodes in the blockchain network verify and accept the block, and upload the video information to the blockchain. The blockchain returns blockchain information containing the video information, such as transaction hash and block hash. The blockchain module saves this blockchain information in a non-relational database to ensure the immutability of the information.

[0025] The user logs in to the system and selects to query or trace the video information. The user module queries the basic information of the video, such as the uploader and review status, in the relational database using the video code. The user module calls the interface that requests blockchain tracing and returns the result to initiate a request to the tracing module.

[0026] The tracing module queries the blockchain information of the video in the non-relational database using the video code. It can also trace on the blockchain through the blockchain information to obtain the video information on the chain. The tracing module compares and verifies the information obtained from the blockchain with the information in the database to ensure the consistency and immutability of the video information. The information for comparison includes the uploader, review status, reviewer information, review conclusion, review time, content classification, publisher, etc.

[0027] The query result is returned to the user, and the user can view the complete information of the video, including detailed information such as the review process, content classification, and publisher. If the information is consistent, the user can trust the authenticity of the video information because it has been verified through the immutability of the blockchain.

[0028] This process ensures that the video information uploaded by the user is recorded on the blockchain after passing the review, and the user can verify the authenticity and integrity of the video information through the system's query and tracing functions. The entire process realizes the traceability and immutability of information through blockchain technology.
