Defending Reality with Code

Proofmode is a technology platform designed to authenticate and verify digital media, developed collaboratively by Guardian Project, WITNESS, and Okthanks since 2013. It provides tools for adding signed C2PA actions, claims, and attestations to media files.

Core Products

• Capture - A mobile camera application with built-in provenance tracking
• Verify - Inspect and analyze multimedia metadata
• Identify - Device verification and attestation signing services
• Connect - Secure communication with media provenance preservation
• Enhance - AI safety through provenance and authentication workflows

Developer Integration

Proofmode provides mobile SDKs for Android and iOS, enabling developers to integrate media authentication and provenance into their own apps. C2PA support is available through:

• C2PA 1.x via SimpleC2PA, built on the C2PA Rust library
• C2PA 2.x (beta) through official mobile SDKs developed with Adobe
• Tools for generating private keys and self-signed certificates on-device
• Legacy libProofMode libraries for custom integration

The technology serves journalists, humanitarian organizations, businesses, and individuals needing to verify media authenticity or establish verifiable proof chains.
