Just take a picture of your manipulated picture/video from the Sony phone. This does not guarantee anything of value.
With your current phone, go ahead and take two pictures - one normal, the other a picture of a picture of that thing
Now look at the two, and tell me you can’t tell in a split second that one is a picture of a picture. There’s a reason that it’s a running joke on the internet that people need to learn to take real screenshot instead of taking a picture of the monitor - there’s always annoying and obvious artifacts.
You’re imagining a future where screen resolution doesn’t improve and lenses can’t solve these issues? Are people really this short sighted?
Except smart phone cameras will also improve - if anything, I’d say that over the last decade, the average smart phone camera has improved at a much faster rate than your average computer monitor.
Combine what I said with all the other Metadata that will be collected, and I’m quite skeptical that you could fool an actual professional with your scheme.
You could easily create a package that couples the authenticated device with a screen showing the faked images and bring that around. If there is a market for inauthentic images that appear authentic, people will easily bypass this technology.
