## Billing Instructions

## File Storage Policy

<FileStoragePolicy uploadedFiles responseType="URL" />

## Application Scenarios

* **Copyright protection**: The author of the image enjoys the copyright according to the law. Adding invisible watermark to the image can prove the copyright ownership of the image for the author or authorized person of the image, and avoid the image being used illegally without the authorization of the author.
* **Preventing information leakage**: In the pictures of confidential information, different invisible watermarks are put on the pictures for different visitors. If the image is leaked, the source of the leak can be investigated by analyzing the invisible watermark.

## Featured Advantages

* **Concealed and reliable effect**: Invisible watermark compared with the traditional stamp watermark, which can not be detected by the viewer, does not affect the picture effect.
* **Resolvability**: The watermark is resolved through the image invisible image watermark interface to prove the copyright ownership of the image.
