![]() ![]() ![]() Perhaps the most unsettling of all deepfake tactics is the manipulation of a person's face. Deep neural networks are iterative, meaning they will continue to improve their output as they process increased amounts of data. Once the deepfaker has what they need, their data is fed into something called a deep neural network, or a computer model that has been trained to recognize a person's or object's key features and use them to generate convincing false video. "For example, if someone wants to create a deepfake of a celebrity, they would gather thousands of images or video clips of that person from different angles, lighting conditions, and expressions," Lyu told Salon. As Liu explained, the AI used to make deepfakes operates by manipulating countless images and video frames of a given target. ![]() How did deepfake technology become so accessible, and so easy to use, that it would usher in a new political and social crisis? To answer this, Salon spoke by email with Dr. Siwei Lyu, the Empire Innovation Professor of Computer Science and Engineering at the University at Buffalo School of Engineering and Applied Sciences, who is an expert in deepfakes. If current trends continue, many others will soon have experiences similar to mine. 28th when "Dilbert" cartoonist Scott Adams tweeted an anonymously-created deepfake of me.ĬhatGPT isn't sentient. That means that even ordinary citizens can also be the subjects of deepfakers' malice, as I learned the hard way on Feb. Indeed, the tools that one needs to create a deepfake are so easy to learn such that even a marginally computer-savvy person can produce a relatively convincing one using off-the-shelf tools. Yet deepfakes are no longer so technologically sophisticated that they require the efforts of intelligence agencies or Hollywood digital artists to produce. ![]() Perhaps most ominously, a deepfake of Ukrainian President Volodomyr Zelenskyy attempted to dupe Ukrainians into believing their military had surrendered to Russia. Even more nightmarish is a scenario where, despite being innocent, the fabricated "evidence" against a person is so convincing that they are unable to save themselves. Yet thanks to a rapidly advancing type of artificial intelligence (AI) known as "deepfake" technology, our near-future society will be one where everyone is at great risk of having exactly that nightmare come true.ĭeepfakes - or videos that have been altered to make a person's face or body appear to do something they did not in fact do - are increasingly used to spread misinformation and smear their targets. Political, religious and business leaders are already expressing alarm by the viral spread of deepfakes that maligned prominent figures like former US President Donald Trump, Pope Francis and Twitter CEO Elon Musk. No one wants to be falsely accused of saying or doing something that will destroy their reputation. ![]()
