Evidence camera
Back to prompt studioCatch a car.
Keep the proof.
Take a live camera image of a passing car. Every image is sealed with a unique challenge, a cryptographic image fingerprint, a device signature, and a link to the image before it.
CAMERA STANDBY
Camera off. Start a secure capture session when ready.
Proof, not just a time: the original image bytes are fingerprinted; every capture uses an unpredictable new challenge; a non-exportable device key signs the record; and each record fingerprints the previous capture. High-accuracy GPS is requested at shutter time and its reported accuracy is sealed too. Altering, replacing, or reordering an image breaks the proof chain. The proof is embedded in the downloaded PNG metadata.
