      Overview

      This document describes how to use the content moderation feature provided by Cloud Infinite (CI). CI fully integrates the processing capabilities with the COS SDK.
      Note:
      To use the content moderation service, you need to have the permission to use CI:
      For root accounts, click here for role authorization.
      For sub-accounts, see Authorizing Sub-Accounts to Access CI Services.
      This document provides an overview of APIs and SDK code samples for image moderation.
      API
      Description
      Scans existing data stored in COS for pornographic, illegal, and advertising images.
      Moderates multiple images in batches.

      Single Image Moderation

      Feature description

      The existing data scan feature of image moderation leverages CI's persistent processing API to scan existing data stored in COS for pornographic, illegal, and advertising images.

      Method prototype

      ImageAuditingResponse imageAuditing(ImageAuditingRequest request);

      Sample request

      //1. Create a job request object
      ImageAuditingRequest request = new ImageAuditingRequest();
      //2. Add request parameters as detailed in the API documentation
      //2.1 Set the request bucket
      request.setBucketName("examplebucket-1250000000");
      //2.2 Set the moderation type
      request.setDetectType("porn,ads");
      //2.3 Set the image location in the bucket
      request.setObjectKey("1.png");
      //3. Call the API to get the job response object
      ImageAuditingResponse response = client.imageAuditing(request);

      Parameter description

      Request has the following sub-nodes:
      Node Name (Keyword)
      Description
      Type
      Required
      ObjectKey
      Name of the image file in the COS bucket. The COS bucket is specified by Host. For example, if the file is img.jpg in the test directory in the examplebucket-1250000000 bucket in Beijing, then Host is examplebucket-1250000000.cos.ap-beijing.myqcloud.com, and ObjectKey is test/img.jpg.
      String
      No
      bizType
      Unique identifier of the moderation policy. You can configure the scenes you want to moderate on the moderation policy page in the console, such as pornographic, adverting, and illegal information. For configuration guidelines, see Setting Moderation Policy. You can get bizType in the console. If bizType is specified, the moderation request will perform moderation based on the scenes configured in the moderation policy. If bizType is not specified, the default moderation policy will be used automatically.
      String
      No
      detectType
      The scene to be moderated, such as Porn (pornography) and Ads (advertising). This parameter will no longer be maintained in the future. You can pass in multiple types and separate them by comma, such as Porn,Ads. If you need to moderate more scenes, use the bizType parameter.
      String
      No
      detectUrl
      You can enter a detectUrl value to moderate an image accessible over the public network. If detectUrl is not specified, the backend will moderate by ObjectKey by default. If detectUrl is specified, the backend will moderate by detectUrl, and there will be no need to enter ObjectKey. Sample detectUrl: http://www.example.com/abc.jpg.
      String
      No
      interval
      For GIF image moderation, you can use this parameter to configure the frame capturing interval. The default value is 5, indicating to capture a frame every five frames starting from the first frame (included).
      Int
      No
      maxFrames
      The maximum number of frames to be captured for GIF image moderation, which must be greater than 0. The default value is 5, indicating to capture five frames at most.
      Int
      No
      largeImageDetect
      Whether to compress the image that exceeds the size limit before moderation. Valid values: 0 (no), 1 (yes). Default value: 0. Note: Images up to 32 MB in size can be compressed, and image compression fees will be charged. For large animated images such as GIF, the compression time is long, which may cause the moderation to fail due to timeout.
      Int
      No
      dataId
      Image ID. This field will return the original content in the result, which can contain up to 512 bytes.
      String
      No
      async
      Whether to moderate asynchronously. Valid values: 0 (returns the result synchronously); 1 (moderates asynchronously). Default value: 0.
      Int
      No
      callback
      The moderation result (in Detail mode) can be sent to your callback address in the form of a callback. This parameter takes effect for async moderation. Addresses starting with http:// or https:// are supported, such as http://www.callback.com.
      String
      No

      Response description

      Success: An ImageAuditingResponse instance is returned upon success, which contains the moderation result.
      Failure: An error (such as the bucket does not exist) occurs, reporting the CosClientException or CosServiceException exception. For more information, see Troubleshooting.
