‘Deepfake’ videos: to believe or not believe?<\/a><\/p>\n

Queen Elizabeth had never before included a dance routine<\/a> in her annual Christmas message, nor had North Korean dictator Kim Jong Un previously warned Americans<\/a> that \u201cdemocracy is fragile\u201d, but that is what they appeared to do in videos that went viral last year.<\/p>\n

Both those videos \u2014 and thousands like them \u2014 were \u201cdeepfakes\u201d that manipulate the speech and actions of politicians and celebrities, using static artificial intelligence-generated faces.<\/p>\n

Although many deepfakes are produced for their comedic or shock value with no intention of misleading viewers, such videos have become a tool for spreading misinformation.<\/p>\n

\u201cWhat is distinctive about deepfakes is that the audiovisual element has a more powerful effect on our psychology than other types of media,\u201d says Jon Bateman, a researcher in Cyber Policy Initiative at the Carnegie Endowment for International Peace.<\/p>\n

In principle, AI could automate the process of media editing and manipulation and make it accessible to anyone, but this method of deception requires huge amounts of training data and technical skills. Other, more straightforward, methods of attacking targets or influencing public opinion already provide a simpler pay-off. <\/p>\n

Manipulated videos that do not use deep learning algorithms \u2014 referred to as \u201ccheapfakes\u201d or \u201cshallowfakes\u201d \u2014 are widespread on social media and can alter opinion even after they are debunked. A video of Nancy Pelosi, US House Speaker, apparently drunk and slurring her words, was created by slowing it down<\/a> but went viral in spite of its obvious fakeness.<\/p>\n

\u201cDeepfakes are a reality but they are impractical to create.\u201d says Andy Patel, an AI researcher at F-Secure, a cyber security group. \u201cShallowfakes are quickly debunked but people still believe them \u2014 so why would you put more effort into it?\u201d<\/p>\n
