Presenting QR Date — Specification and reference library for signed timestamps inside QR codes that can be used to independently, and beyond reasonable doubt, verify the date and time a photo was taken in near-realtime photojournalism, uploads, and live streams. 🧵 Wait, what?

We've made some updates to the site in the past week: - "Sonify" plays the URL as an audible MT63 encoded signal between 1-3kHz, which you can play in the background while capturing video footage. - We've added a background that induces a Moiré pattern around the QR code.

We're currently working on distributing the clock source for qrdate.org so that everyone can validate the timestamps together. We will be setting up a roughtime server and joining the ecosystem, and encourage other parties to do so as well.

Hey there; I'm taking a look at QR Date, a way to tag images with a trusted time stamp. @miuott has been working on this for almost a week now and I've given some of my own contribution too. cendyne.dev/posts/2022-03-03…

QR Date, a trusted timestamp for real-time media

A new tool: QR Date, a signed timestamp inside a QR code that you can use to verify the date in near-realtime photojournalism.

When capturing a photo or video, you can either show the QR Date from your phone or tablet (or any sort of screen), or by printing it out and holding a physical paper up. For more info, see the about page: qrdate.org/about

Spread the word! We want to help NGOs and journalistic organisations take this idea and implement their own clock sources, and to take over ours. For more information on the URL spec, API and initial reference library on Github; check out our website. qrdate.org
