Image copyright mark
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
Write a short author or project identification before publishing your photographic works, and keep the original camera photos, exported files and release time records.
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.
Add batch identification for self-owned product pictures or authorized operation materials to avoid adding obvious text watermarks on the surface of the picture.
