Blockchain-powered Full Stack Citizen Photo Journalism

Everyday thousands of people are bullied, blackmailed, silenced and scammed online using fake photos, fake videos and misinformation. It is getting easier to (i) selectively edit photos, videos and audio, (ii) manipulate metadata of media content and (iii) even generate fully artificial videos (Eg: deepfakes). Fakes are used to spread misinformation and create socio-economic and political chaos. This is leading us towards a post-truth dystopia. Also, sometimes malicious people falsely accuse genuine videos (or photos, audio) as fakes, to promote their self-interests. In this talk, I will present an implementation of a Blockchain-powered 'truth machine' (a mobile app) to enable a global borderless decentralized citizen photo journalism. Our technology incentivizes the spread of truth and controls misinformation before it spreads. Our app lets anyone create, share, buy, sell and trade unedited, unfiltered, verifiable and tamper-evident photos and videos. The users may choose to be anonymous, pseudonymous or use their real identities. Our built-in blockchain provides a verifiable certificate to prove that they are not fake or photoshopped or deepfaked.  Our mission is to put a truth machine in everyone's pocket and enable a global borderless citizen photo journalism and true photography. Our built-in marketplace provides new economic opportunities for photographers, photo journalists and anyone with an iOS device. Every photo, video and audio created using True Dat app is a unique cryptographically-signed, verifiable and tamper-evident asset. The provenance and the digital rights of these assets are securely tracked and seamlessly transferred using our EulerChain blockchain.
