"Study: Smart Devices' Ambient Light Sensors Pose Imaging Privacy Risk"
According to researchers from the Computer Science and Artificial Intelligence Laboratory (CSAIL) at the Massachusetts Institute of Technology (MIT), ambient light sensors are vulnerable to privacy threats when embedded in a smart device's screen. The team has presented a computational imaging algorithm to recover an image of the environment from the perspective of the display screen using these sensors' subtle single-point light intensity changes in order to show how hackers could use them in conjunction with monitors. The MIT team discovered that ambient light sensors can capture images of users' touch interactions in the absence of a camera. These sensors can pick up on common gestures such as scrolling, swiping, or sliding and gather information on how users interact with their phones while watching videos. This article continues to discuss the study on smart devices' ambient light sensors posing privacy risks.
