When snapping a photo, couldn't a phone produce a hash with date/time/location included? I understand it's not bullet-proof, but at least it would make it possible to verify the original to some degree.
- wongarsu 2y agoLeica signs images in the camera in their new M11-P (and presumably future cameras that cost less than $9000). Canon, Nikon and Sony are also working on adding this to their future cameras. And thanks to Lightroom integration that signature can be preserved through edits, with a trail of what you changed. Maybe at some point this will also trickle down to smartphone cameras. Though with the tiny sensors mandated by the smartphone form factor there is always a lot of preprocessing going on, and it's hard to draw a clear line between just clearing up the sensor data and simple beauty filters. But the examples in the article seem pretty clear cut https://leica-camera.com/en-int/photography/content-credentials https://leica-camera.com/en-int/photography/content-credenti...
