Apple's anti-deepfake tech signs photos at the sensor and develops them in an auditable cloud
deanwball · x · 2026-09-22
Dean Ball unpacks Apple's new anti-deepfake approach: the camera sensor cryptographically signs every pixel of a digital "negative," which is then "developed" in Apple's cloud where all image processing steps occur — making the pipeline legible and auditable, unlike on-device processing that can be corrupted with or without the user's knowledge.
He argues this matters most in the judicial system, where he has long worried AI-manipulated media could gum up the works: letting forensic experts inspect image processing in Apple's secure cloud is far better suited to proceedings where the truth of evidence really matters. A rare example of thoughtful AI-era work from Apple, he says.
