      Original Image Protection

      CI provides the original image protection service to protect source files from being requested by malicious users. Original image protection needs to be used together with CI's style feature. For more information about the style feature, please see Style Setting. After original image protection is enabled, image files in the bucket can only be accessed at style URLs.
      Suppose the original image URL is http://examplebucket-1250000000.picsh.myqcloud.com/picture.jpg and the style1 style has been set for the examplebucket-1250000000 bucket. Once the original image protection feature is enabled, the image can be accessed only at http://examplebucket-1250000000.picsh.myqcloud.com/picture.jpg?style1 but not the original image URL.
      Note:
      The original image protection feature supports only CI domain names, such as examplebucket-1250000000.picsh.myqcloud.com.
      This feature is usually suitable for scenarios such as original image resource hotlink protection and business anti-cheating. For example, you can save the watermark parameters as a style and enable original image protection, then the image files in the corresponding bucket can be accessed only at the URLs with the watermark style.
      You can also call the Enabling Origin Protection API to enable original image protection.

      Directions

      1. Log in to the CI console, click Bucket Management on the left sidebar, and click the desired bucket to go to the bucket management page.
      2. Click Bucket Configuration on the left and find Original Image Protection on the right.
      3. Click Edit, change Status to Enabled, and select Image Type. * indicates enabling original image protection for all image types.
      4. Click Save.
