Quick answers to the most common questions:
What is C2PA and how does it work?
C2PA adds cryptographically signed metadata ("manifests") to media files containing provenance information. Any tampering breaks the signature, making modifications detectable. It uses standard PKI (like HTTPS certificates), not blockchain.
Can C2PA be removed? Can it detect AI-generated images?
Removal: Yes, by design. C2PA proves authenticity when present, rather than preventing removal.
AI Detection: Not automatically. C2PA records what creators declare. AI tools must voluntarily label their output as "AI-generated" in manifests.
Which cameras and software support C2PA?
Cameras: Leica (M11-P, SL3), Sony (Alpha 1, A9 III, A7S III, A7 IV), Nikon (Z6 III planned for 2025) can sign photos at capture time.
Software: Adobe Photoshop/Lightroom, Capture One, and many open-source tools.
Cost: The standard and tools are free. Certificate fees: ~$50-500/year.
