AI content watermarking embeds imperceptible signals
Unlike traditional visible watermarks used in photography, AI content watermarks are typically invisible to humans and can only be detected and deciphered algorithmically. The concept is distinct from the watermarking of AI models themselves (to prevent model theft) and from the watermarking of training data (to combat unauthorized data use). Modern AI watermarking schemes are typically formalized as a pair of algorithms, an embedding (or generation) algorithm and a detection algorithm, sharing a secret key.
Example
An AI-generated image of a landscape with an invisible watermark embedded can be traced back to the AI system that created it.
AI content watermarking helps address concerns about misinformation, deepfakes, copyright infringement, and the traceability of synthetic content.
