"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.
