Watermarking
Digital watermarking is a technique that embeds identifying information into the audio signal itself, used to trace the origin of content or its processing chain. It is a form of embedded trace.

The proof dimensions of hashes, watermarks, and signatures are mutually independent: a hash proves "the content has not changed", a watermark proves "the origin or processing path", and a signature proves "the key approved this payload".
Metadata tags can be easily stripped, which is why watermarks are needed to provide 'strong binding'.
Whether major AI companies such as Anthropic have deployed watermarking mechanisms in production environments has not been publicly disclosed.
Labelling refers to explicitly informing users at the content level that the content is AI-generated, and is visible to users; watermarking refers to embedding imperceptible technical markers within the content, which are typically invisible to users.
