You may remember the 1987 Schwarzenegger movie "The Running Man" where Arnold's character is convicted of a crime he didn't commit, based on a fake video. That tech didn't seem realistic in the 80s, but experts warn it pretty much is now; and if you think you've seen fake news, 'you ain't seen nothin' yet.'
Hao Li is a video producer in LA. He told CBS we're close to being able to completely fake a video.
"It may be a year, actually."
Li says our enemies could use this technology to make it appear the President said something he didn't.
"I was kind of concerned in the beginning because -- you can imagine right? You can do all kinds of like, evil things with it."
Or, as in "The Running Man," the government could fake a video of a political enemy committing a crime he didn't commit to send him to prison.
Dave Dorman at DARPA -- the federal government agency that invented the Internet concept -- told CBS there are definitely national security concerns.
"It can cause unrest, it can cause riots; other nation states could even act on some of this stuff."
Dorman says he's working on software that can spot the digital fakery.
"My vision is to have a program that every image, every video, posted to a social media site, go through this process."
Without it, Dorman says you may one day see a video that shows the President saying something he didn't really say.
