Proof Mode: Verifying the Authenticity of Digital Content

Proof Mode is a decentralized tool developed by the Guardian Project that enables users to verify the authenticity of digital content, such as photos and videos. By gathering additional data and using cryptographic techniques, Proof Mode establishes a trustworthy chain of custody, proving that the content is not manipulated or fabricated. Journalists, human rights defenders, and individuals documenting various events can utilize Proof Mode to provide irrefutable evidence. The verification process involves elements such as PGP signatures, open timestamps, and verifications from third-party services like Google Safety Net. Therefore, users can independently verify the authenticity of content without relying on centralized authorities.
