Description

Proofmode helps anyone capture and verify smartphone photos and videos of actual reality. It enhances trusted visual metadata, authenticates camera hardware, cryptographically signs content, and uses third-party notaries for a decentralized, privacy-focused chain of custody.

In short, it helps people know your photos and videos are really real.

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.

Recent changes:
- updated branding, look and feel
- improved camera
- fix for ARM 32-bit device crashes
- updated C2PA support
- experimental autosync-to-cloud feature

Comments on Proofmode: Verifiable Camera for Android

★★★★★ Kyle Wooten · Feb 26, 2022

I have yet to be able to use this application, but I am very excited about using it because I think that simply that idea about what it does in the functions that is it does in the library instead of hold are so valuable

★★★★★ Philip Thomas · Apr 15, 2017

Great for when you need to prove when and where a photo was taken, as I don't store location data in photos by default.

★★★★☆ Gabriel · Jan 8, 2023

The app works, but I would like it to work with any file type (at least audio). Canging the file extension seems to work as a workaround, though.

★★★★★ John Mark Wildenthal · Mar 1, 2017

Everyone should have this app. If you ever want your pictures or video to be taken seriously by media, police, or courts, this level of cryptographic documentation is going to be necessary.

★★☆☆☆ Kurt Vurt · Nov 6, 2019

Doesn't seem to work on Galaxy S9+. I keep getting the "No proof exists yet. Try again in one minute" error when I try to Share Proof a regular pic from Gallery. Any ideas?

★★☆☆☆ Roger Sherman · Nov 23, 2021

Easy to use and no ad.s. "Visuals" ha-ha, two stars for the concept attempt (it almost gives the public AmericA bar association worthy camera evidence - something like this could make Calif. Prop. 65 a real Law). It is really where it needs to be: unfunctional (it sits in the background without generating proof until expostfacto tapped) - whilst Manual Camera app reports camera2 NO raw data camera support.

★☆☆☆☆ Trevor Elliott · Mar 3, 2022

Doesn't work at all, but looks nice. I've had it on my phone for months and months, but it's never been able to generate any proofs. Share pic, no proof exists, press generate proof, press basic or robust (didn't matter), spins for over 30 min and still nothing. I've tried multiple times over the past several months with different pictures and everything. Kept it on the phone hoping an update would eventually make it work, but nope. S20 Ultra, Android 11 & tried on newest update of Android 12.
