About this APK

Proofmode Capture is an app by The Guardian Project in the Photography category, listed since at least February 2021. It includes native code only for x86 64-bit, so it won't install on ordinary ARM phones (only on x86 devices such as emulators and some Chromebooks).

Since version 2.6.0-RC-3, the APK grew from 38 MB to 79.9 MB and the minimum Android version rose from 7.0 to 9. It asks for 19 permissions, 7 of them sensitive, including precise location, camera and record audio. It asks for the same permissions as version 3.2.0-BETA-2.

What's new in v3.3.0-RC-1

• Improved: Smoother camera: rebuilt photo and video viewfinders with a fixed tap-to-focus indicator • FIX: More frequent GPS updates for accuracy improvements • New: Auto Sync keeps your captures and proof data backed up automatically - with support for IPFS via Filebase • BETA: Creator Assertion (CAWG.io) support for identity signing and creator, copyright and notes metadata

Description

From the listing uploaded by “appupdater”.

Proofmode helps anyone capture and verify photos and videos of actual reality. In short, it helps people know your photos and videos are really real. It enhances trusted visual metadata, authenticates camera hardware, cryptographically signs content, and uses third-party notaries for a decentralized, privacy-focused chain of custody. 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.
