Satellite image display The expansion of large internment camps in Xinjiang, China between 2016 and 2018 provides some of the strongest evidence Government suppression More than one million Muslims have triggered international condemnation and sanctions.

Other aerial images—such as Iran’s nuclear facilities and North Korea’s missile bases—have similar effects on world events.Now, image processing tools are possible artificial intelligence It may make it more difficult for people to accept the surface value of such images.

In a paper published online last month, the University of Washington professor Bo Zhao Use AI technology similar to that used to create so-called AI technology Further study Change the satellite images of several cities. Zhao and his colleagues exchanged features between the Seattle and Beijing images to show buildings that Seattle does not have, and removed the buildings and replaced them with Beijing’s green plants.

Zhao used one algorithm call Loop GAN Manipulate satellite photos. The algorithm was developed by researchers at the University of California, Berkeley, and has been widely used in various image deceptions.It trains an artificial Neural Networks Identify key features of certain images, such as painting style or features on a specific type of map. Then, another algorithm helps improve the performance of the first algorithm by trying to detect when the image is manipulated.

Like deepfake video clips designed to show people a compromise, such images may mislead the government or spread on social media, spread misinformation or doubt about true visual information.

“I definitely think this is a big problem. It may not affect ordinary citizens tomorrow, but it will play a bigger role behind the scenes in the next ten years,” said Grant McKenzieAssistant Professor of Spatial Data Science at McGill University in Canada, not involved in this work.

“Imagine a world in which the state government or other actors can actually manipulate the image, either showing nothing or showing a different layout,” MacKenzie said. “I’m not entirely sure what can be done at this point to stop it.”

Some crudely processed satellite images have gone viral on social media, including photo India, which claims to show that India is lit up during Diwali, is obviously handcrafted. It may only be a matter of time before the use of more sophisticated “deep forged” satellite images to conceal weapon installations or falsely defend military operations.

Gabriel LinResearchers at the Schoenstein Center at Harvard Kennedy School who specialize in media manipulation say that without artificial intelligence, maps can be used to mislead.She pointed Pictures circulating on the Internet Implying that Alexandria Ocasio-Cortez is not in the place she claimed during the congressional uprising on January 6, and a Chinese passport Show disputed areas The South China Sea is part of China. “There is no fancy technology, but it can achieve similar goals,” Lim said.
