My prediction: verified video will start to become a thing.
Phones will be able to encode a digital signature with a video that certifies the date, time, and location where the video was captured. Modifying the video in any way will invalidate it.
Same for photos.
People will stop believing photos and video that don’t have a verifiable signature. Social networks and news organizations will automatically verify the signatures of all photos and videos they display.
Technically this is already possible today, it just needs to become mainstream and the default.
Even that isn’t possible. While you could confirm it hasn’t been modified via hashing, it can only confirm that after it was created. If you created an entirely new file there’s no way to prove it wasn’t faked and then had a signature applied.

Also, what’s to stop you from generating new hash information that is consistent with the new media if you do modify an existing one?
The timestamp of the original hash being sent to a central server.
That’s the whole point of sending that hash close to when it happens.
