Proofmode vs eWitnessMedia

Proofmode is a system that enables authentication and verification of multimedia content, particularly captured on a smartphone, from point of capture at the source to viewing by a recipient. It utilizes enhanced sensor-driven metadata, hardware fingerprinting, cryptographic signing, and third-party notaries to enable a pseudonymous, decentralized approach to the need for chain-of-custody and “proof” by both activists and everyday people alike. ProofMode is currently available as specifications, developer libraries and applications. We seek to expand its support for notarization and sharing of proof through decentralized storage technology. We believe in a future, where every camera will have a “Proof Mode” that can be enabled and every viewer an ability to trust what they are seeing. ProofMode supports the Coalition for Content Provenance and Authentication (C2PA) standard, Content Credentials and the Content Authenticity Initiative.

In an era of deepfakes, generative AI imagery, and rampant photo manipulation, the simple question "is this real?" has never been harder to answer. Misinformation and disinformation are escalating threats to journalism, public safety, and trust in democratic institutions. Verifying digital images from unknown sources has become an essential part of the editorial process in the news industry. Social media platforms bear a corporate responsibility to establish trust in authentic content, recognize tampering early, and prevent circulation of images that do not come from verified sources. eWitness addresses this challenge by registering a SmartHash fingerprint of every photo or video on an immutable blockchain at the moment of capture — making the chain of custody permanent and publicly verifiable.
