Description

Vouch is a simple, open-source tool that lets any camera, smartphone, or app "digitally sign" media at the moment of capture. It embeds secure metadata (who, when, where) that proves a photo or video is original and unaltered. This creates a "chain of provenance" for digital content. It’s not a deepfake detector; it’s an authenticity verifier. Social media, news, and legal systems can then prioritise or reward "Vouched" content, rebuilding trust in what we see online.

Detailed Idea

Alignment with DF goals (BGI, Platform growth, community)

Problem description

Misinformation and AI-generated deepfakes are destroying trust on a global scale. It's becoming impossible to distinguish real footage from a real event from a sophisticated fake. Existing "fact-checking" and "AI detection" tools are reactive; they are always one step behind the generators. We are losing the ability to believe what we see, which has severe consequences for journalism, justice, and social stability.

Proposed Solutions

An open-source standard (SDK/API) that integrates with cameras, phones, and creative software. When a user captures a photo or video, Vouch creates a cryptographic signature and stores it as metadata before the file is saved. This signature acts as a digital notary, proving the file's origin and that it hasn't been tampered with. Any platform can then instantly check this signature. A Vouched checkmark becomes the new standard for authenticity, just like a Verified checkmark is for identity.
