Whether at the airport, in a cafe or in a waiting room, more and more people are using their computers in public places and in view of others.
The software company, Oculis Labs, has created a program that protects on-screen data from prying eyes. The program, called PrivateEye, marries face recognition technology with encryption.
The PrivateEye program uses the camera that is embedded in most computers. The program takes a snapshot of the user’s face when he’s working on the computer. Whenever the user looks away, the program scrambles the image on the computer, making it impossible to read anything. That way, whether the user gets up for coffee or just looks away for a second, the security of the screen is never compromised. When the user returns, the program identifies the user’s eyes and makes the screen legible again.
Even more crucial, the camera recognizes faces other than the user’s. If the camera detects that someone other than the user looking at the screen, it scrambles the image, thus defeating any potential eavesdropping.
For those who really need to make sure their screens are safe in public, this software keeps out nosy neighbors and spies alike.
