    How much detail would you like?

    Practical

    Can complement origin clues, but is not a universal proof for all AI content.

    Example scenario: A team checks an image for an existing SynthID watermark.

    Document supported generation and testing procedures and observe detection limits.

    At a glance

    Core
    Depending on the method, image, audio, video or text signals are changed during generation, so that a suitable detector can check a watermark. This must be distinguished from visible hints and metadata.

    Limits
    Viewing the missing signal as evidence of human creation; overestimating processing resistance; confusing watermarks with fact checking.

    In context

    Generative AI

    Generative AI generates new content or data patterns based on learned distributions.

    AI Transparency

    Provide comprehensible information about the use, properties and limitations of an AI system.

    Questions about this term

    Does a negative result prove that no AI was involved?

    No. Not every content is marked with the tested procedure.

    All details and background

    ELI5 – Explained simply

    An invisible marker can show which production method was used.

    Why it matters in practice

    Can complement origin clues, but is not a universal proof for all AI content.

    Example

    Example scenario: A team checks an image for an existing SynthID watermark.

    Pitfalls and limits

    • Viewing the missing signal as evidence of human creation; overestimating processing resistance; confusing watermarks with fact checking.

    Origin & history

    Google DeepMind added text and video watermarks to SynthID 2024.

    Use in mid-sized companies

    • Document supported generation and testing procedures and observe detection limits.
