1930s fraud-detection mathematics, still working today — just aimed at a target it was never built for. Challenge: catch an AI-generated JPEG using nothing but a 1938 statistical law. No neural network involved. Benford's Law: in real-world numerical data, the leading digit isn't uniformly distributed — 1 shows up ~30% of the time, 9 under 5%. Holds for river lengths, electricity bills, physical constants... and, it turns out, for the AC coefficients in a JPEG's DCT blocks, if the image actually came from a capture-and-compress pipeline. I run this as one of six checks in snapWONDERS' analyse pipeline: 8×8 DCT on every block, absolute value of the AC coefficients (DC term excluded — it doesn't follow Benford), leading digit extracted, binned against the classic log10(1 + 1/d) curve, then a chi-squared goodness-of-fit test. Above threshold, it's flagged. It's not a standalone verdict — heavy resampling or repeated re-saves can trip it too, same as a genuinely synthetic image would. So it feeds a combined score alongside five other signals rather than deciding anything alone. But as a zero-training, zero-black-box check, it's a genuinely satisfying one: an accounting fraud-detection tool from 1938 has something real to say about whether a photo actually came out of a camera.

@bibliolater@social.vivaldi.net "As the realism and availability of GAI continue to increase, it is now—more than ever—critical to understand this threat and develop strategies to mitigate potential harms to individuals, organizations, and democracies." https://jov.arvojournals.org/article.aspx?articleid=2818019 A dangerous development! Especially with the known bias in AI training (gender, racism etc.) #faces #deepfake #FakeImages #GAI #aiEthics

NPR: Class action suit against AI makers over deepfake child sexual abuse material expands "...New plaintiffs in a class action lawsuit against Elon Musk's AI company, SpaceXAI, allege that the company's image-generation models were used to create child sexual abuse material and that the company failed to adequately share information about an alleged perpetrator with authorities...." https://www.npr.org/2026/07/09/nx-s1-5885052/spacexai-stabilityai-deepfake-csam-class-action #ai #deepfake #grok #csam #legal

#Scientists Asked #AI to Impersonate 112 Public Figures. What Happened Next Is a ‘Dire’ Warning AI #chatbots that were prompted to #impersonate public figures produced responses that people perceived to be more authentic, coherent, and relevant than the real thing, a finding that underscores “a dire need to inform the general public of the potential harm this can have on society,” according to a study published on Wednesday in PLOS One. #security #plosone #artificialintelligence #deepfake

@revogt@mastodontech.de hat auch die Aktennotiz im #eID-Repo gelesen, nach der schon seit mindestens 19. Mai klar gewesen sei, dass der Online-Ausstellungsprozess nicht gegen #Deepfake schütze. Die angedachten Gegenmassnahmen lassen aber nichts Gutes erahnen: Die "Integrität von Endgeräten" soll gestärkt werden. Wahrscheinlich bedutet das, dass nur Geräte von Apples und Googles Gnaden erlaubt sind und Alternativen wie das sicherere #GrapheneOS nicht. @digiges@mastodon.social @adfichter@infosec.exchange
