ProofMode and related tools are the only open-source camera software with built-in decentralized cryptographic provenance and authentication capabilities. Not only do we develop our own apps, we also create developer libraries to integrate into third-party apps, including prototypes for Signal, along with integration in popular human rights documentation tools like Tella and Save by OpenArchive. Lastly, we are active participants in the Coalition for Content Provenance and Authentication (C2PA), and contribute to the development and ports of the C2PA OSS toolkits.
