Try it. Record something off the screen (including the audio), and see what happens. I'm yet to see one example of that that looks like reality.
Emulating a sensor sounds like it immediately reduces the number of perpetrators by orders of magnitude.
I agree though, what I'm suggesting is not 100% bulletproof, but it's using a proven technology, and it's relatively simple, assuming hardware manufacturers are willing to add one small chip to their cameras.
- asciimo 9y agoI've seen a number of YouTube and liveleak videos that were obviously made by recording a security monitor with a phone. Seems to be an acceptable practice for certain genres, and is usually credible.
- olegkikin 9y agoThat's not his point. He is claiming he can record a fake video that plays on a screen, and the resulting recording will look like a recording of reality, not of the screen (and the camera will sign it as such).
- gregmac 9y agoWhich only makes things worse, because if you are trying to create fake security camera footage, you just need to make it real enough to play back on a "security monitor" and record that with a phone camera.
- CM30 9y agoIf you're pretending it's footage of a film, TV show or video game, then recording from the screen will fool a lot of people. And while in a lot of cases that would make the 'metadata' aspect useless anyway, there's always the possibility of a hoaxer either saying: 1. This was recorded from a TV broadcast 2. Or a CCTV camera Etc.
