Can reflections in eyeglasses actually leak info from Zoom calls? Here's a study into it
Boffins at the University of Michigan in the US and Zhejiang University in China want to highlight how bespectacled video conferencing participants are inadvertently revealing sensitive on-screen information via reflections in their eyeglasses.
"Our work explores and characterizes the viable threat models based on optical attacks using multiframe super resolution techniques on sequences of video frames," the computer scientists explain in their paper. "The present-day 720p camera's attack capability often maps to font sizes of 50-60 pixels with average laptops," explained Yan Long, corresponding author and doctoral candidate at University of Michigan, Ann Arbor, in an email to"Such font sizes can mostly be found in slide presentations and the headings/titles of some websites ."
