Deepfakes have risen in prominence in a few short years. What first started off in the deep, seedy underbelly of the internet for erotica purposes has burgeoned into a vast operation with tinkerers swapping faces of celebrities and politicians, or manipulating video and audio to actually “put words” into a person’s mouths. The latest deepfake to take the internet by storm comes from EZRyderX47 on YouTube. He took an iconic film scene and replaced two of the main characters with “updated” actors that are very popular today. The movie is the 80’s classic Back to the Future, which stars Michael J. Fox and Christopher Lloyd. But in...

Artificial intelligence has frequently been used to better identify people and objects. But can AI also be used to mask someone’s identity? Facebook recently announced that it has created video de-identification technology that can hide people from facial recognition. Facebook has combined an “adversarial autoencoder” and a “trained-face classifier”. An autoencoder is an artificial neural network that learns a representation for a set of data unsupervised. Adversarial autoencoders were introduced in 2016 and are able to “match the aggregated posterior of the hidden code vector of the autoencoder with an arbitrary prior.” Classifiers typically use an algorithm...

How do you defeat “deepfakes”? According to Google, you develop more of them. Google just released a large, free database of deepfake videos to help research develop detection tools. Google collaborated with “Jigsaw”, a tech “incubator” founded by Google, and the FaceForesenics Benchmark Program at the Technical University of Munich and the University Federico II of Naples. They worked with several paid actors to create hundreds of real videos and then used popular deepfake technologies to generate thousands of fake videos. Researchers will be able to freely access both the fake and real videos to develop “synthetic video detection methods”....

If a new report is to be believed, deepfake technology is about to ramp up the realism factor while making it increasingly more accessible to the general public. While this is an interesting development for people that like to do this sort of digital trickery for fun; in the age of "fake news" it has the potential for creating more upheaval considering how quickly videos can go viral on social media. According Hao Li, a University of Southern California (USC) associate professor of computer science, deepfake videos have the potential to look "perfectly real" within six to 12 months from now. In many cases with current technology, you can often tell that videos have been altered. This...
