About ProofMode

A collaboration between Guardian Project, Okthanks and WITNESS

We believe in a future, where every camera will have a “Proof Mode” that can be enabled and every viewer an ability to verify-then-trust what they are seeing.

ProofMode is a system that enables authentication and verification of multimedia content, particularly captured on a smartphone, from point of capture at the source to viewing by a recipient. It utilizes enhanced sensor-driven metadata, hardware fingerprinting, cryptographic signing, and third-party notaries to enable a pseudonymous, decentralized approach to the need for chain-of-custody and “proof” by both activists and everyday people alike.

ProofMode supports the Coalition for Content Provenance and Authentication (C2PA) standard, Content Credentials and the Content Authenticity Initiative.

How can I use ProofMode today?

ProofMode is ready to use and publicly available as production mobile apps, desktop tools, developer libraries and verification processes. We also provide training and support for the use of resilient decentralized storage technology through our PRESERVE Process.

Please see our projects page for the latest details.

ProofMode is free and open-source software, available on Gitlab and Github

This work has been done as a collaborative effort between Guardian Project, WITNESS, and Okthanks for nearly a decade. Guardian Project is partially supported by Rights Action Lab, a nonprofit 501(c)(3) charitable organization.

We have been primarily sponsored by Witness and the Filecoin Foundation for the Decentralized Web.
