ProofMode captures, authenticates and verifies smartphone multimedia from source to recipient. It enhances metadata, fingerprints hardware, cryptographically signs content, and uses third-party notaries for a decentralized, privacy-focused chain of custody—empowering activists, journalists, and everyday people.

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."
- Sam Gregory, Witness.org 2013

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