Store description excerpt
Proofmode helps anyone capture and verify photos and videos of actual reality. In short, it helps people know your photos and videos are really real. It enhances trusted visual metadata, authenticates camera hardware, cryptographically signs content, and uses third-party notaries for a decentralized, privacy-focused chain of custody. 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 supports the Coalition for Content Provenance and Authentication (C2PA) standard, Content Credentials and the Content Authenticity Initiative.
