OP vs EXIF Metadata
EXIF data contains useful camera and location information — but it's trivially strippable, easily editable, and most social platforms remove it on upload. It was never designed to prove authenticity.
Where EXIF Metadata Falls Short
EXIF Metadata has a place, but it wasn't designed for provenance.
Most platforms strip EXIF on upload — Facebook, Instagram, Twitter, and messaging apps remove EXIF data to protect user privacy, destroying any provenance signal.
Anyone can edit EXIF fields — tools like ExifTool make it trivial to change timestamps, GPS coordinates, camera model, and author fields.
No cryptographic integrity — EXIF data is plain text embedded in the file header. There's no way to verify it hasn't been tampered with.
No signer identity — EXIF records the camera model, not the person who captured or approved the content.
How OP Is Different
OP uses the C2PA standard to embed cryptographic provenance directly in the file.
Cryptographically signed — the C2PA manifest is protected by a digital signature. Any modification invalidates the hash.
Standard-based tamper evidence — C2PA was specifically designed for content provenance, unlike EXIF which was designed for camera settings.
Signer identity is verifiable — the manifest includes the certificate chain of whoever signed the file, not just a text field.
Designed to survive workflows — C2PA-aware applications preserve manifests through editing and re-export operations.
