London, May 31 (ANI): Frustrated with unwanted people looking at your computer screen? Inventors Martin Ek and Bo Larsson have developed software to alert you whenever there is 'shoulder surfer' around.
The new system uses front-facing cameras usually found on netbooks and laptops, reports New Scientist.
It makes the screen of the computer go blank, whenever more than more than one face is in front of the device.
However, selected friends can be permitted to read your screen through facial recognition software. (ANI)
