## What is Proofmode?

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 is currently available as specifications, developer libraries and applications. We seek to expand its support for notarization and sharing of proof through decentralized storage technology. We believe in a future, where every camera will have a “Proof Mode” that can be enabled and every viewer an ability to trust what they are seeing.

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

### 4/5 — New, but promising

*2025-06-03*

There are only a few alternatives at present for dealing with content authenticity and this a solid choice especially if you’d prefer not being tied to a specific vendor ecosystem.  I like that the app is spare and mostly doesn’t get in the way. Excited for advancements in the future.

### 5/5 — An app to combat AI

*2025-06-02*

ProofMode is easy to use and maintains the media’s integrity. It allows you to verify and sign photos and videos, so there is no doubt about its authenticity. You determine the levels of verification and it’s simple to change the settings at anytime. I highly recommend ProofMode. It’s free and open source! I love that it provides the level of trust I need in today’s shifting realities.
