“Seeing is no longer believing”
A deepfake is a type of artificial intelligence used to create convincing images, including audio and video hoaxes. Deepfakes are often created for malicious purposes.
Why should I be concerned about them?
The spread of misinformation through deepfakes and other tactics generates mistrust of online content and undermines the credibility of news and information available.
The University of Florida community can be impacted by deepfakes. Here are some scenarios:
A video of the university president is posted in which he announces the cancellation of classes for the remainder of the semester
A video of an industry celebrity mentioning that if the viewer clicks on the link below, they will be able to talk with them. The link is actually a malicious link designed to steal personal information
How can I spot a deepfake?
Some indicators to identify a deepfake video clip include:
Facial features that are blurrier than the environment
Lip movements not in sync with the audio
Eye and eyebrow movements that seem unnatural, such as irregular blinking
Inconsistencies in lighting or shadows in the video
Be a skeptic! If you are unsure about the validity of a video, ask yourself the following questions:
What is the working behind deepfakes?
To create a deepfake, the facial features of an individual are matched with those of a lookalike using an artificial intelligence algorithm known as the variational auto-encoder (VAE). In addition, a machine learning technique called generative adversarial network (GAN) is used to detect and fix inconsistencies in deepfakes, making them more believable.
