About this app

BETA WARNING: This is an early release and has not been fully audited technically or tested in court or other legal proceedings.

ProofMode is light, minimal "reboot" of our full encrypted, verified secure camera app, CameraV (https://guardianproject.info/apps/camerav). Our hope was to create a lightweight, almost invisible utility, that you can run all of the time on your phone, that automatically extra digital proof data to all photos and videos you take. This data can then be easily shared through a "Share Proof" share action, to anyone you choose.


ProofMode is an open-source project: https://github.com/guardianproject/proofmode

Goals

* Run all of the time in the background without noticeable battery, storage or network impact
* Provide a no-setup-required, automatic new user experience that works without requiring training
* Use strong cryptography for strong identity and verification features, but not encryption
* Produce "proof" data formats that can be easily parse, imported by existing tools (CSV)
* Do not modify the original media files; all proof metadata storied in separate file
* Support both full "proof" data generation, as well as more simple sha1/sha256 hash and PGP signature of media files
* Do not require a persistent identity or account generation

Contributions

* Some icons were used under the APL 2.0 license from the Google Material Design Icon library: https://material.io/icons/
* The App Intro library is used under the APL 2.0 license: https://github.com/paolorotolo/AppIntro
* Spongy Castle uses the same adaptation of the MIT X11 License as Bouncy Castle.: https://rtyley.github.io/spongycastle/

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 30min 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.

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 realLaw) . 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.

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 ShareProof a regular pic from Gallery. Any ideas?
