Image copyright mark

Add blind watermark

For original or authorized pictures, write hidden text tags that can be identified by the analysis process of this site. The appearance usually does not change significantly after annotation, but different pictures and processing links may produce differences; it is suitable as auxiliary information for source verification, and cannot replace copyright registration and preservation of complete evidence.

Suitable for these scenarios

Which pictures are suitable for adding blind watermarks?

📸

Marking before original photography is released

Write a short author or project identification before publishing your photographic works, and keep the original camera photos, exported files and release time records.

🎨

Design draft and illustration version management

Write distinguishable marks for different delivery objects or versions, and the contract, source document and delivery record still need to be combined during subsequent verification.

🛍️

Product image source auxiliary tracking

Add batch identification for self-owned product pictures or authorized operation materials to avoid adding obvious text watermarks on the surface of the picture.

Operation path

How to add and save verification materials

  1. Upload original or authorized pictures and wait for the system to check whether the invisible blind watermark compatible with this site is included.
  2. Enter a short, identifiable author, project or batch identifier to avoid writing sensitive personal information.
  3. Generate and download the annotated image, while saving the unprocessed original image, annotated content and operation time.

Suggestions for improving the success rate of subsequent parsing

  • Use the parsing tool to verify once before publishing, and retain the original file with successful verification.
  • Social platforms may re-compress, crop or convert formats. It is recommended to avoid saving only the version downloaded from the platform.
  • Copyright disputes need to be integrated with original documents, creation records, contracts and release times, and cannot only rely on one analytical diagram.

Frequently asked questions

Add blind watermark frequently asked questions

Must the blind watermark be completely invisible?

There is no guarantee. The appearance changes in most pictures may not be obvious, but the specific visibility is related to the image texture, annotation method and display environment. You should check the annotation results by yourself.

Can it still be parsed after cropping, compressing and scaling?

Not necessarily. Mild processing is sometimes still discernible, but strong compression, heavy cropping, screenshots, filters, and format conversions can all destroy hidden information.

Can the blind watermark analysis results be directly used as legal evidence?

It can only be used as one of the auxiliary verification materials. The actual probative power needs to be judged based on the original documents, creation records, contracts, credible timestamps and the complete evidence collection process.
