A new online technique called deepfake is causing people to be worried about more fake news and other things that can mislead people. The word “deepfake” is a combination of “deep learning” (which is an important part of artificial intelligence) and “fake” (which means not real). Deepfake software allows people to replace part of a picture or video with another picture or video image. The result is a fake video. The software means you can put your face over the face of a talking president or movie star. This process will make your face speak in the voice of that president or movie star. Many people are worried the technology will be used during national elections. Deepfake videos could be used to trick voters.
