Our research proposes near-term mitigations including a software prototype that users can use to blur the eyeglass areas of their video streams.” ~ The study “Our models further show that the evolution towards 4K cameras will tip the threshold of text leakage to reconstruction of most header texts on popular websites.

In the future, when 4K cameras are common, that risk increases at least a little.

Will 4K Cameras Be Able to Capture Smaller Text?Ĭurrently, the study found, the danger of a reflection revealing data through a present-day 720p webcams is fairly low, since it will only work for big fonts. The 10 mm reflection size tends to map to font size of between 50 and 60s pixels, according to an email from Long to The Register. The “over 75%” statistic refers to perscription glasses, which yielded better results than the more reflective blue-light blocking glasses in the study, due to a smaller curvature. “Our models and experimental results in a controlled lab setting show it is possible to reconstruct and recognize with over 75% accuracy on-screen texts that have heights as small as 10 mm with a 720p webcam.” The team included researchers Yan Long, Chen Yan, Shilin Xiao, Shivan Prasad, Wenyuan Xu, and Kevin Fu, who paired mathematical modeling with human subject experiments to figure out just how small a reflection could be before the text could no longer be reconstructed. The study, titled “Private Eye: On the Limits of Textual Screen Peeking via Eyeglass Reflections in Video Conferencing,” was conducted by researchers at the University of Michigan in the US in tandem with those at the Zhejiang University in China.

Unless you're on a Zoom call while also taking a headline-sized look at your bank details or password list, you'll be safe. So why shouldn't you be worried about it? Because the common webcam resolution, 720p, is only capable of reading font sizes of 50-60 pixels, or the size of a particularly large headline.

By posting to /r/Twitch, you accept these rules and accept that subreddit moderators reserve the right to remove posts at their discretion.Could your eyeglasses reflect the screen you're looking at, leaking otherwise private information to others on a video call with you? Weirdly, the answer is yes.Ī recent study has found that popular video conferencing softwares like Zoom or Google Meet can record the glasses reflection of a computer screen in enough detail to recreate the text on that screen.
