This is rather expensive for what looks like a home 3D printed toy with some cute software. Other than that it's a 16MP Sony CMOS, I'd expect a pretty noisy picture... How do I get my photos off the camera? Coming soon. We're working on export functionality to get your photos off the camera. It would be more interesting if the software was open source.

It wouldn't work at all as open source since you could just modify the source to sign your AI generated pictures.

What concerns me most in the era of gen AI irt photography is journalism. We need truth, most especially when limited-means citizen journalism is the only reliable source of that truth.

But I feel like the only way to accomplish fool-proof photos we can trust in a trustless way (i.e. without relying on e.g. the Press Association to vet) is to utterly PACK the hardware with sensors and tamper-proof attestation so the capture can’t be plausibly faked: multi-spectral (RGB + IR + UV) imaging, depth/LiDAR, stereo cameras, PRNU fingerprinting, IMU motion data, secure GPS with attested fix, a hardware clock and secure element for signing, ambient audio, lens telemetry, environmental sensors (temperature, barometer, humidity, light spectrum) — all wrapped in cryptographic proofs that bind these readings to the pixels.

In the meantime however, I'd trust a 360deg go-pro with some kind of signature of manafacture. OR just a LOT of people taking photos in a given vicinity. Hard to fake that.

I’m not seeing what this is product is trying to solve? A zero knowledge proof to say it isn’t AI ? I think you could do this with a disposable camera or Polaroids and a photo scanner that makes the zero knowledge proofs .

What proof is there that the photo scanner is scanning a genuine photo and not something AI generated that looks like a Polaroid?

What proof is there that this camera is photographing a genuine scene?

This looks like a hipster toy. It’s possible that this could have value in journalism or law enforcement. Just make it look the part. Make it black and put some decent lens on it.

I'm pretty sure forensic cameras already exist for this purpose. And as far as I can tell, there isn't really any bulletproof way to do this other than embed a signing key in the camera and hope no one manages to extract it, rendering the whole thing pointless. I guess you could have a unique signing key per camera and blacklist known leaked keys.

Canon and Nikon both did this. You paid a premium for a “signature analysis” app. The target was for things like law enforcement, where authentication was important.

They got cracked with a year or two. Not sure if they still offer the capability.

Recalling an old scandal about an office copier/scanner which was doing some OCR cleanup and changing numbers.

This is patently incorrect. Just remember the whole TiVo affair and reasons why GPLv3 was born. Source code availability does not guarantee ability to run it on the particular device.

it would. it would just require pki and a secure enclave that lives directly on the imaging chip to support it.
