Google opened SynthID Detector to the public on Tuesday 7 October, a tool that says whether an image, a video or a sound carries the invisible watermark of its AI. The same day, Wired describes an "organic literature" label for books written by humans, the "Balance ton Claude" collective defends in Le Monde its investigation into a novel it judges machine-produced, and an American court sentences Michael Smith to eighteen months in prison for collecting more than $8 million by streaming AI-generated music through fake accounts. Four separate facts, one and the same shift: proving a content's origin becomes an economic function.
We observe that the market is building, this week, the infrastructure of provenance. Google's watermark seeks to become a standard, adopted by OpenAI, Nvidia, Kakao and Apple. The human-literature label plays on paper the same role as the detector on the image: attesting an origin. The prison sentence, for its part, puts a price on deception, $8 million in royalties diverted, the annual revenue of a mid-sized independent label, built on tracks nobody composed.
For a French organisation, the content it publishes will have to carry its origin. A client, a judge, soon the AI Act and its obligation to flag generated content, will ask to show what comes from a human, what comes from a model, and who answers for it. The reflex that gets ahead is set up now, without waiting for the check: document the origin of what you produce, who wrote it, with which model, on what date, and keep that record. Train teams in two twin gestures, declaring AI assistance in their own work, and reading provenance signals on what they receive, a SynthID watermark, the absence of a source, an image that is too smooth.
Trust in writing and images becomes again an asset that is proven. The company that can say where its content comes from will turn the imposed transparency into a sign of seriousness, on the day everyone has to answer for what they sign.
