It's already implemented in a limited number of cameras recently. A hardware key proves which camera it came from, and a blockchain hash proves at least when the camera first connected to the internet after taking the photo. So, if anyone tries to claim your photo as their own, you need only point to the blockchain to prove it's actually yours. It also proves you didn't use any beauty filters outside the camera hardware security bubble. https://news.adobe.com/news/news-details/2022/Adobe-Partners-With-Leica-and-Nikon-To-Implement-Content-Authenticity-Technology-Into-Cameras/default.aspx https://news.adobe.com/news/news-details/2022/Adobe-Partners... I predict it's going to go mainstream in a new iPhone model eventually. Consumers will become sold on the idea of authenticity. They are sick of fakes and filters, but didn't yet have any way to prove something is real.
