How Hardware Photo Provenance Works
Modern mobile sensors utilize embedded hardware enclave chips to generate a cryptographic hash of raw photodiode data at the precise instant of capture. This signature is bound to a C2PA metadata manifest and paired with PRNU (Photo-Response Non-Uniformity) sensor grain analysis to detect synthetic AI generation or localized software editing.
