This is how it works. Oculis Labs has PrivateEye for general use and Chameleon for extra protection. Both programs rely on the embedded cameras that are common computer features. A snapshot of the user’s face is taken by the two programs while he is working on his computer. Once the user looks away, the user’s image is scrambled by the programs. This way, whoever tries to peek into the computer would have a hard time reading anything on the computer. Security is assured whenever the user is not in front of his computer.
