Knowledge MaxxingDigital watermark
A digital watermark is a signal embedded directly into a piece of media's content, detectable by software, that can indicate the content was generated or modified by AI.
Prerequisite: Content Credentials
What matters
Because it's embedded in the content itself rather than in separate metadata, a watermark can sometimes survive being re-saved or shared through channels that strip other metadata.
Example
An AI image generator might embed a watermark imperceptible to the human eye but detectable by a dedicated tool checking whether an image was AI-generated.
Common misconception
A digital watermark is not always robust to every kind of editing or compression; some watermarking techniques can be degraded or removed by sufficiently aggressive modification.
Recall question
Why can an embedded watermark sometimes survive steps that strip other metadata?
