This looks interesting. I love the retro styling and transparent case. The proofs and selling it as some sort of fight-back against AI seems tenuous and as the user controls the hardware - going to be hard to keep that system hermetically sealed due to giving the user the keys on device. Also though almost nobody actually cares very much about attesting that their photos are somehow real and untouched by AI.

There are larger problems when you consider this question. What is real and not in photography is a long and storied debate - any photograph is ultimately a curation of a small part of the real world - what is just out of frame could completely change the interpretation of the viewer if they saw it, regardless of whether the picture is unaltered after taking. The choice of framing, colours, subject etc etc can radically alter meaning. There is no getting away from this.

So ultimately I don't think the biggest problem facing photography is attested reality. I actually think the democratisation of photography offers a better way out - we have so many views on each event now that it's actually harder to fake because there are usually hundreds of pictures of the same thing.

PS for the site author, there is a typo in the sentence beginning - remove the an 'By combining sensors, an on-device zero-knowledge proofs'.
