A Deepfake is a combination of AI technologies for cloning faces and voices to create lifelike computer-generated videos of a real person. Since fraudsters are able to use this technology to manipulate and imitate the facial features and personality traits of people in the real world, there is cause for legitimate concern about its use for various shady activities. An example of this:
The CEO of a British company was tempted to transfer €220,000 to an unknown bank account because he believed he was on the phone with the CEO of the parent company. In reality, the voice belonged to a fraudster who had used Deepfake voice technology.
Blockchain was cited as a legitimate tool to combat the various digital threats posed by Deepfake technology. In this respect, Blockchain allows users to digitally sign and confirm the authenticity of various video or audio files. The more digital signatures are added to a particular video, the more likely it is to be considered authentic.
