Researchers at the University of California San Diego and the University of Wisconsin-Madison have developed a smart LED system to protect people from unwanted photography, for example due to copyright or privacy reasons. The system produces a flickering fattern that interferes with camera sensors on mobile devices.
“We developed LiShield, a smart LED ‘light shield’ which deters illegal photography of sensitive physical objects, such as people, museum art, or documents, and automatically enforces the visual privacy protection without any user intervention,” Shilin Zhu, one of the researchers on the project, said.
