Deepfake Awareness Video
The name deepfake comes from the terms “deep learning” and the word “fake” (Shao, 2019)
Deepfakes are fake videos and/or audio recording of real people. These videos are altered using machine learning artificial intelligence and are often very realistic and indistinguishable from a real video. This machine learning technique is called generative adversarial networks (Schwartz, 2018). This can make a fake video of someone say or do something that they never have said/done before, be very convincing.
A deep fake could be swapping the faces of two different people. For example: Person A has a video of them acting in front of a camera. Someone replaces Person A’s face with Person B’s face. And now Person B is copying everything Persona A is saying and doing.
Another kind of deep fake is the manipulation of the facial features. For this one, it doesn’t necessarily need two people. There would be a video of Person A and the person who is doing the deep fake can track the facial points and use their own camera to speak. This results with Person A imitating whatever the person mimed them to do. This is often paired up with an audio whether it is real or fake.
Another kind of deep fake is the manipulation of body limbs. For this one, this could either be using two video sources of two different people or one source from one person and the video by the deep faker themselves.
There are quite a lot of Deep fakes in the internet, however a lot of them are for fun such as having Nicholas Cage’s face on different actors/actresses of other movies.
However, Deep fakes have been used maliciously either towards a person or to spread political deception and/or manipulating users.
