TL;DR: The new Reimage feature on the Google Pixel 9 phones is really good at AI manipulation, while being very easy to use. This is bad.
I really don't have much knowledge on it but it sound like it's would be an actual good application of blockchain.
Couldn't a blockchain be used to certify that pictures are original and have not been tampered with ?
On the other hand if it was possible I'm certain someone either have already started it, it is the prefect investor magnet "Using blockchain to counter AI"
How would that work?
I am being serious, I am an IT and can't see how that would work in any realistic way.
And even if we had a working system to track all changes made to a photo, it would only work if the author submitted the original image before any change haf been made, but how would you verify that the original copy of a photo submitted to the system has not been tempered with?
Sure, you could be required to submit the raw file from the camera, but it is only a matter of time untill AI can perfectly simulate an optical sensor to take a simulated raw of a simulated scene.
Nope, we simply have to fall back on building trust with photo journalists, and trust digital signatures to tell us when we are seeing a photograph modified outsided of the journalist's agency.
Yep, I think we pictures are becoming a valuable as text and it is fine, we just need to get used to it.
Before photography became mainstream the only source of information was written, it is extremely simple to make a fake story so people had to rely on trusted sources. Then for a short period of history photography became a (kinda) reliable sources of information by itself and this trust system lost its importance.
In most cases seeing a photo means that we were seeing a true reflection of what happened, especially if we were song multiple photos of the same event.
Now we are arriving at the end of this period, we cannot trust a photo by itself anymore, tampering a photo is becoming as easy as writing a fake story. This is a great opportunity for journalists I believe.
There has never not been a time when photography was not manipulated in some way, be it as simple as picking a subject and framing it in a specific way can completely change the story.
I really enjoy photography as a hobby, however I find it a bit embarrasing and intrusive to take photos of other people, so my photos tend to look empty of people.
I will allways frame a picture to have no or as a very few people in it as possible.
In general I don't edit my photos on the computer, I just let them speak for themselves, even if that story is a half truth.
We have never been able to trust photographs completely, though you make a good point about truth in numbers, that won't go way just because of AI.
The big issue now is how easiy it is to make a completely believably faked photo out of an existing photo, we have been able to do this for decades, but is has been way, way harder to do.
As for the blockchain making photos valuable, we tried that, NFTs as a concept is dumb and has failed, I don't believe that NFTs will be the future of ownership.
