Proofmode Capture

Proofmode is a powerful Chrome extension designed to help users capture and verify the authenticity of smartphone photos and videos. It enriches visual content with trusted metadata, authenticates camera hardware, cryptographically signs media, and employs third-party notaries within a decentralized and privacy-focused chain of custody. Supporting industry standards like the Coalition for Content Provenance and Authentication (C2PA), Content Credentials, and the Content Authenticity Initiative, Proofmode ensures content integrity from capture to viewing.

By using Proofmode, activists, journalists, and everyday users can confidently prove the reality of their visual content. The extension is available alongside mobile apps, desktop tools, and developer libraries, complemented with training and support for decentralized storage via the PRESERVE Process. Proofmode paves the way for a future where every camera features a "Proof Mode" enabling users to verify and trust what they see.
