[0046] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0047] First, the terms involved in one or more embodiments of the present application are explained.

[0048] A smart contract is a program that automatically executes, manages or verifies contract terms on a blockchain. It is self-executing and automatically triggers corresponding actions when specific conditions are met.

[0049] Blockchain is a decentralized distributed ledger technology in which all transactions or data records are stored in the form of blocks. Each block is linked together through encryption to ensure that the data cannot be tampered with and is transparent.

[0050] Content compliance review refers to the use of technical means to check whether the video content complies with platform or legal regulations to ensure that it does not contain illegal, infringing, sensitive or inappropriate content.

[0051] Oracle is a tool that connects blockchain with the outside world and can provide external data to blockchain, such as copyright information, real-time data, etc.

[0052] Natural language processing (NLP) is a technology that allows computers to understand, analyze, and generate natural language. In this application, it is mainly used to analyze the subtitles and descriptions of videos to determine whether they contain illegal words.

[0053] Figure 1 The flowchart of the video file review method based on smart contract according to one embodiment of the present application is shown, and the method is executed by the video platform, wherein the video platform is implemented based on blockchain, such as Figure 1 As shown, the method comprises the following steps:

[0054] Step S101, obtaining a video file to be reviewed and corresponding video metadata.

[0055] When any object produces a video file, it can publish the video file produced by it through the video platform, and the video platform needs to review the video file before publishing the video file. Therefore, the method provided by this embodiment can be used to review the video file.

[0056] Specifically, the video platform can provide a video publishing page to the uploader, and a "publish button" is provided in the video publishing page. The uploader can upload the video file to be published by clicking the "publish button" and enter the video metadata corresponding to the video file. The video platform can obtain the video file uploaded by the uploader and the corresponding video metadata. In addition, the video platform can also generate a unique video identifier for the video file, where the video metadata includes: video identifier, uploader identifier, video title, video description information, video file hash value, copyright statement information and other data. The video file hash value is used to verify the integrity of the content. The video file hash values ​​of different video files are different. Even if the video file has only a slight change, its corresponding video file hash value is completely different, so the video file hash value can be used to verify whether the video file has been modified.

[0057] By obtaining video metadata, after completing the video file review, the video metadata and review-related information can be stored together in the blockchain to ensure that the data cannot be tampered with and is transparent and traceable. When there are doubts about the review-related information in the later stage, it is convenient for confrontation.

[0058] Step S102, creating a smart contract instance according to the video metadata and the smart contract template in the blockchain.

[0059] After obtaining the video file to be reviewed, it is necessary to conduct a file review on the video file to be reviewed. What is deployed in the blockchain is the smart contract template, which has not been instantiated. Therefore, the smart contract template deployed in the blockchain can be called to create a smart contract instance based on the video metadata and the smart contract template in the blockchain, that is, the video metadata is used as input data and filled into the corresponding position of the smart contract template to realize the instantiation of the smart contract.

[0060] When multiple video files need to be reviewed at the same time, the video metadata of multiple video files can be used as input data and filled into the corresponding positions of the smart contract template to realize the instantiation of the smart contract.

[0061] Step S103: Based on the smart contract instance, the video file to be reviewed is reviewed according to preset review rules to obtain a review result.

[0062] After creating a smart contract instance, the audit process can be automatically triggered based on the created smart contract instance according to the preset audit rules to audit the video file to be audited. Specifically, the video file can be audited in many aspects, such as copyright compliance audit, content compliance audit and moral review. After completing the file audit, the corresponding audit result can be obtained. The audit result can be passed or failed. The video that passes the audit can be identified as a compliant video, and the video that fails the audit can be identified as an illegal video. The audit result can also include: content information that fails the audit, etc. The specific audit result can be set according to actual needs.

[0063] Step S104: Based on the smart contract instance, the video metadata, file review process, and review results of the video file to be reviewed are packaged into blocks and stored in the blockchain.

[0064] After obtaining the audit results, the video metadata, file audit process, and audit results of the video file to be audited can be packaged into blocks through smart contract instances, packaged to generate blocks, and then stored in the blockchain. By recording the video metadata, file audit process, and audit results in the blockchain, the transparency and non-tamperability of the file audit process and audit results are guaranteed. Therefore, when the uploader has doubts about the audit results, it can confront them by querying the information recorded in the blockchain.

[0065] According to the video file review method based on smart contracts provided in the embodiments of the present application, smart contracts are called to automatically review video files according to preset review rules, thereby reducing manual intervention, reducing labor costs, improving platform review efficiency, and ensuring the compliance of video files published by the video platform. The file review process, review results, and video metadata are recorded in the blockchain through smart contracts, thereby achieving transparency and traceability of the review and improving the fairness of the review process.

[0066] Figure 2 A schematic diagram of a video file review method based on a smart contract according to an embodiment of the present application is shown. Figure 2 As shown, the method comprises the following steps:

[0067] Step S201, obtaining the video file to be reviewed and the corresponding video metadata.

[0068] Step S202: Create a smart contract instance based on the video metadata and the smart contract template in the blockchain.

[0069] In this embodiment, step S201-step S201 and Figure 1 Steps S101 and S102 in the illustrated embodiment are similar and will not be described in detail here.

[0070] In step S203, the smart contract instance is connected to the preset copyright database through the oracle, and the copyright compliance audit is performed on the video file to be audited by querying the preset copyright database to obtain the copyright compliance audit result.

[0071] Smart contracts run on the blockchain, and their execution environment is deterministic and closed. Therefore, they do not support direct interaction with external data sources. Therefore, they can be connected to the preset copyright database through an oracle. The preset copyright database stores the copyright status information of each video and one or more of the following information: video files, video frames, video feature vectors, video file hash values, etc., so that the copyright status information of the video file to be reviewed can be determined by querying the preset copyright database, thereby performing a copyright compliance review on the video file to be reviewed, and obtaining the copyright compliance review result corresponding to the video file to be reviewed, where the copyright compliance review result may include: passing the copyright compliance review or failing the copyright compliance review.

[0072] In an optional implementation of the present application, the video metadata includes: a video file hash value; therefore, the smart contract instance can send a copyright status query request to the oracle, wherein the copyright status query request carries a video file hash value and / or video features. After receiving the copyright status query request, the oracle can query the preset copyright database according to the video file hash value and / or video features, and compare the video file hash value and / or video features of the video file to be reviewed with the video file hash value and / or video features recorded in the preset copyright database. In the case of the comparison, the copyright information corresponding to the video file recorded in the preset copyright database is determined, thereby obtaining the copyright status information corresponding to the video file to be reviewed. The copyright status information can be: obtaining adaptation authorization or not obtaining adaptation authorization; obtaining public permission or not obtaining public permission; the smart contract instance performs a copyright compliance review on the video file to be reviewed according to the copyright status information returned by the oracle and the preset copyright compliance review rules. For the case of failure to pass the review, the smart contract instance will automatically mark the video file to be reviewed, marking it as abnormal or marking it as failing the copyright compliance review. At this time, the video file will be blocked from being released. For example, the preset copyright compliance rule may be that the copyright status information is not authorized for adaptation or not publicly licensed, which means that it can be considered as not passing the copyright compliance review; the preset copyright compliance rule may be that the copyright status information is authorized for adaptation or publicly licensed, which means that it can be considered as passing the copyright compliance review. This is just an example and does not have any limiting effect.

[0073] Here, oracle technology is used, and the smart contract instance can automatically call the external copyright database to quickly compare the video content with the videos with registered copyrights to ensure copyright compliance.

[0074] In step S204, the smart contract instance calls a preset content review tool and / or uses a preset content review method to perform a content compliance review on the video data of the video file to be reviewed, and obtains a content compliance review result.

[0075] Specifically, smart contract instances can also be used to perform content review on video files to be reviewed. Here, the main purpose is to review whether there is abnormal content in the video data (video frames and / or text information and / or audio data) based on content compliance rules. Abnormal content can be sensitive words, image content that does not comply with platform regulations, and text content that does not comply with platform regulations.

[0076] In an optional implementation of the present application, the smart contract instance can call an image recognition tool to perform image recognition on the video frames of the video file to be reviewed, wherein the image recognition tool is a pre-developed and designed SDK, for example, it can be Google Vision, AWS Rekognition, and the smart contract instance can call the image recognition tool through the API interface, and the image recognition tool can extract key video frames from the video file to be reviewed, and then perform in-depth analysis on the key video frames to detect whether there is abnormal content in the image content of the video frame, where the abnormal content mainly refers to some image content that is not suitable for display. The specific review process can refer to the review process in the prior art, which will not be repeated here.

[0077] In an optional implementation of the present application, there may be some sensitive information in the subtitles or video description information or audio data of the video file to be reviewed, and this sensitive information is not suitable for publication. Therefore, the smart contract instance uses a natural language processing method to perform a text content review on the text information of the video file to be reviewed to determine whether the text information contains abnormal content. For audio data, the smart contract instance can first call a speech-to-text tool to convert the audio data into text information through the speech-to-text tool, and then use a natural language processing method to perform a text content review on the converted text information to determine whether there is abnormal content in the audio data. Among them, the smart contract instance can call an SDK with a natural language processing function through an API interface to perform a text content review on the text information of the video file to be reviewed. The specific review process can refer to the review process in the prior art, which will not be repeated here.

[0078] In step S205, the smart contract instance calls a sentiment analysis tool to perform sentiment analysis on the voice data and / or text information of the video file to be reviewed to determine whether there is any abnormal content in the voice data and / or text information.

[0079] For audio data, the smart contract instance can first call the speech-to-text tool to convert the audio data into text information. The smart contract instance can call the sentiment analysis tool through the API interface to perform sentiment analysis on the voice data and / or text information in the video file to be reviewed to identify whether there is inappropriate content that is extremely negative or other abnormal emotional states.

[0080] Step S206: If the audit result is the first result, the smart contract instance presets a mark on the video file to be audited and executes the publishing logic of the video file to be audited.

[0081] If the audit result is the first result, that is, passed the audit, which means passed all audits, the smart contract instance will automatically mark the video file to be reviewed with a preset mark, for example, marked as "compliant" and pushed it to the video platform for release.

[0082] Step S207: If the audit result is the second result, the smart contract instance sends an exception notification to the upload object or performs preset processing on the upload object account.

[0083] If the review is the second result, that is, all reviews have not passed, for example, the copyright compliance review has not passed, and / or the content compliance review has not passed, and / or the ethical review has not passed, then the smart contract instance sends an exception notification to the uploader, prompting the uploader to modify or delete the video file; or, performs preset processing on the uploader's account, for example, restricting the uploader's upload permissions, or deducting credit points in the uploader's account.

[0084] Among them, sending abnormal notifications to the upload object, performing preset processing on the upload object account, and publishing video files can all be considered as audit decision execution operations.

[0085] Step S208, based on the smart contract instance, the video metadata, file review process, review results, review decision execution operation, and review basis of the video file to be reviewed are packaged into blocks and stored in the blockchain.

[0086] In order to improve the fairness of the audit process, after the audit is completed, the video metadata of the video file to be audited, all audit processes, audit results, audit decision execution operations and audit basis (such as copyright database query, image recognition results, etc.) can be packaged into blocks and stored on the blockchain based on the smart contract instance, thereby ensuring the transparency and immutability of the results. It should be noted that the audit process can be recorded at any time during the audit. In addition, abnormal content can also be recorded in the blockchain at the same time.

[0087] In an optional implementation of the present application, after the uploader uploads the video file, the video file to be reviewed will enter a pre-release stage. In this stage, the video file to be reviewed can accept review reports from other users. The user who makes the report is referred to as the reporting object. The reporting object can report on the copyright, error information, and abnormal content of the video file to be reviewed. Therefore, the reporting data sent by the reporting object can be received here; the smart contract instance can count the number of reporting objects. If the number of reporting objects is greater than or equal to the preset reporting number threshold, a secondary review notification is sent to the review end, wherein the secondary review notification can carry the reporting data. By triggering the manual review procedure, the review accuracy can be improved to avoid the inability to publish the video file uploaded by the uploader due to incorrect review.

[0088] In an optional implementation of the present application, if the smart contract instance encounters a complex or ambiguous situation (such as a situation where the content is uncertain, etc.), the manual intervention mechanism can also be automatically triggered. The smart contract instance notifies the review end according to the preset notification rules (such as the appearance of sensitive words, etc.), and the review end manually reviews the video file to be reviewed, and makes a final judgment according to the platform rules to obtain the corresponding manual review results. The manual review results will be recorded in the blockchain through the smart contract instance, and the review status in the blockchain will be updated, for example, reviewed.

[0089] According to the video file review method based on smart contracts provided in the embodiments of the present application, copyright compliance review, content compliance review and ethical review of videos are automatically executed through smart contracts, thereby avoiding the limitations and errors of manual review, reducing manual intervention, and improving review efficiency; all review records (including file review process, review results, review decision execution operations, review basis, etc.) will be written into the blockchain to ensure the transparency, traceability and non-tamperability of the review records, improve the fairness of the review process, and ensure the security of the video platform. For some complex or ambiguous review situations, the smart contract will trigger the manual intervention process to ensure the accuracy of the review.

[0090] Figure 3 The following is a schematic diagram of the framework for video file review based on smart contracts. Figure 3 As shown in the figure, during the review, video metadata, user reporting data, and data from external data sources will be provided to the smart contract as external input data. The smart contract can obtain the corresponding review results based on copyright compliance rules, content compliance rules, reporting trigger conditions, and ethical review rules. In the case of copyright non-compliance, the uploader will be notified to modify or delete the video file; in the case of content non-compliance, the uploader's permissions will be restricted; when the reporting number threshold is reached, manual review will be initiated; when all reviews are passed, the video file will be allowed to be released; in addition, all review records will be packaged into blocks and stored in the blockchain.
