API Overview
The Blind Watermark Verification API provides the ability to add invisible text watermarks to images. By covertly embedding watermark information in the frequency or spatial domain of an image, it enables copyright protection and tracking. This API supports requests via image URL or Base64 encoding and allows for custom watermark text.
Use Cases
- Copyright Protection: Add invisible watermarks to original images and photography to prevent unauthorized use and distribution.
- Data Leak Prevention: Embed employee information or timestamps into confidential corporate documents or images to easily track the source of leaks.
- Content Tracing: Add platform identifiers or user IDs to user-uploaded images on social media and e-commerce platforms for content tracing.
