Don't forget law enforcement, customs or any high(ish) stakes sector which needs to be able to trust the images they show as evidence as well.

Back in the day Canon and Nikon tried this with embedded private keys on their cameras, and with Sandisk's WORM SD cards. Then, somebody extracted the keys and it was game over.

While my iPhone 17 can't match a full frame mirrorless camera, it can take pretty impressive photos, so they are already more than adequate in detail and clarity department. So making these images trusted is a huge win for them.
