South Korea’s president recently ordered a crackdown on an epidemic of digital sex crimes targeting women and girls who become the unwitting victims of deepfake pornography.
About Deepfakes:
Deepfakes are synthetic media, including images, videos, and audio, generated by Artificial Intelligence (AI) technology that portray something that does not existin reality or events that have never occurred.
The term deepfake combines deep, taken fromAI deep-learning technology (a type of machine learning that involves multiple levels of processing), and fake, addressing that the content is not real.
It can create people who do not exist, and it can fake real people saying and doing things they did not say or do.
Background: The origin of the word “deepfake” can be traced back to 2017, when a Reddit user with the username “deepfakes”, posted explicit videos of celebrities.
Working:
They are created by machine learning models, which use neural networks to manipulate images and videos.
To make a deepfake video of someone, a creator would first train a neural network on many hours of real video footage of the person to give it a realistic “understanding" of what he or she looks like from many angles and under different lighting.
Then they combine the trained network with computer-graphics techniques to superimpose a copy of the person onto a different actor.
Deepfake technology is now being used for nefarious purposeslike scams and hoaxes, celebrity pornography, election manipulation, social engineering, automated disinformation attacks, identity theft, and financial fraud.
They differ from other forms of false information by being very difficult to identify as false.
