The New & Frightening Technology of Falsified Video

Daisy Ridley's face on a porn performer's body. Made using FakeApp.

The dawn of Photoshop was a scary thing in many respects. In this day and age pictures of people, even very convincing pictures, can be faked with startling accuracy. Today video is the gold standard for truth. Faking video is much more expensive than faking photos, generally takes much more time, and most importantly is very difficult to do with any amount of accuracy when it comes to making it seem like someone did something they didn't do.

New, tantalizing breakthroughs in machine learning and video editing technology have now crossed this barrier.

Mimicking people has long been the holy grail of video for some time now. From young Princess Leia's appearance in the recent Rogue One Star Wars movie to young Tony Stark in the Captain America: Civil War movie, we've been dancing around the edge of complete believably for false people in video for some time now.

However, machine learning advances have taken things to the next stage, allowing a single individual or small team with powerful enough computers to create false video relatively easily. Just look at this video of President Obama giving the same speech in several different ways. The original video and sound were captured, then the computer was able to fake several copies with, from what I can tell, near flawless accuracy.

Oh, and did I mention that people are already using this stuff to make porn?

In a truly terrifying display of the capabilities of this technology, a new trend of Deep Fakes, machine learning created video of famous women edited to look like they are engaged in explicit sex acts on camera, has begun to take hold. Forget having your sex tape leak.... they can make a realistic sex tape from scratch now, whether you made one or not. I can't imagine what it must feel like to watch yourself be made to do perform some act on camera that you'd never do on camera... if at all.

On the other hand, much like today with photos, the emergence of falsified video gives a much better level of plausible deniability than ever before. Once the idea that videos can be falsified begins to take hold, people will begin to question what they see a lot more. The results, much like with photos, will likely be mixed. This technology isn't coming: it's already here. And there really isn't any going back.

Take a look at President Obama's fake speech videos below:

Oh man, this is such a coincidence! Just had a conversation about this a few days ago. It is creepy isn't it

Yeah, the future is weird. And yes, very, very creepy. Stuff like this is probably only going to get worse. Especially with virtual reality getting more and more realistic...

Interesting writeup! This is an important topic.
"Daisy Ridley's face on a porn performer's body."
Well I don't know who she is, so the fake video clip was meaningless to me. Some actress I assume? (I avoid the mainstream completely nowadays!)
One thing it makes me think about... what happens to all that "unique" video that I've captured over the last 15 years? Once it can all be created, perhaps even better than the original, from scratch...... won't all my digital pics and videos be less unique?

In theory. Then again, many of your photos could probably be faked. The question is, why would anyone devote the necessary time and energy unless you were super famous or they had something else to gain?

No, I think most of us are safe for now. And Daisy Ridley is the main character in the new Star Wars films.

You're right, I don't think anyone is likely to falsify photos or videos of me.
But I was thinking more about the implications this development has.
If all my unique photos (once-in-a-million captures of a bird flying across a sunset, for example) can be created "from scratch", aren't they in some way devalued? As printer technology improves, will some collectibles lose value? Like old baseball cards found in grandpa's attic... but no way to prove they are "real". How about currency in rectangular paper or plastic sheets? Soon, if not now, the counterfeiters are having a field day with inexpensive state of the art printers.
What if I've been holding a video clip of my late relative, to use to claim an inheritance, or prove my innocence, or something important? In a few years, won't that video clip be almost meaningless, because someone can just say "it might be fake"?
I think this has bigger implications than just worrying about our face being pasted onto a porn star's body. : )

I think b the answer is probably no.... So long as there is some way to identify the real from the fakes. Remember that while photo doctoring has become more robust, so to has skepticism and investigative power.

In much the same way a photo might be deemed as fake well trust that it is real unless we have reason to believe it is fake, namely that some third party makes such a claim.

And as a guy (I assume you're a guy) of course you aren't quoted about having your head pasted onto a porn star' body. But I think it shows 'the bigger implications' just fine. What is the most embarrassing thing a person can do on camera? A sex act. I think this is going to drive it home for people more viscerally than bird photos and last wills and testaments. :).

But my point is, people can say (and often do) that it might be fake now. These lines are going to blur.

nice post, thanks for sharing

It is amazing technology and will only get better and real time replacement will be a filter in a video editor. Adobe have also gotten a technology which can learn someones voice and then speak for them. I is an interesting point that we will not be able to believe our own eyes and have Fakenews 2.0.

This is going to pick up the pace in the next half a decade or so.
