Spot DeepFake Video Checklist

Spot DeepFake Video Checklist 1

Deepfake is a AI generated video and image manipulation method to create fake videos which are very convincing. Designed to intentionally mislead and spread misinformation. The technology can also create  entirely fictional photos from scratch and create voice skins / clones.

So what is deepfake? Really it’s the new version to ‘Photoshopping’ for the 21st century. Using a form of artificial intelligence (AI) called deep learning to make images for fake events so its name evolved as deepfake. 

There is so much fake news shared on social media these days but the new trend of deepfake videos can be very realistic and understandably very believable so help spread of misinformation. Social media and messaging sites compress  videos to make them quicker and easier to share, this removes may critical clues.

Because of the damage these fake videos can have there has been a challenge set to identify fakes. The Deepfake Detection Challenge (DFDC) launched by Amazon, Microsoft, and Facebook.

The impact on people with the use of deepfakes, along with other fake news, is the creation of a zero-trust society. No one will know what to trust so will no longer bother to try to distinguish truth from fake news.

Poor Quality

Like all videos look at the quality.

High-definition fake videos easiest to detect as more detail in a video, means more opportunities to see its flaws. But compressed videos for social media help cover these tell tale signs.

Look out for strange lighting effects and inconsistent illumination and reflections.

How are Deepfake videos made?

Firstly you need to run thousands of face shots of the two people into a AI algorithm called an encoder. The encoder learns and identifies similarities between the faces by reducing them to shared common features, and compressing them.

Then a second AI algorithm called a decoder  recovers the faces from the compressed images. Then  one decoder recovers the  face, and another decoder to recover the other.

Swapping faces is as simple as feeding encoded images into the “wrong” decoder.
