Explanation:
Viewing confidential information on someone’s monitor is known as shoulder surfing. By moving
their monitors so they cannot be seen, the executives are preventing users passing by ‘shoulder
surfing’.
Shoulder surfing is using direct observation techniques, such as looking over someone’s shoulder,
to get information. Shoulder surfing is an effective way to get information in crowded places
because it’s relatively easy to stand next to someone and watch as they fill out a form, enter a PIN
number at an ATM machine, or use a calling card at a public pay phone. Shoulder surfing can also
be done long distance with the aid of binoculars or other vision-enhancing devices. To prevent
shoulder surfing, experts recommend that you shield paperwork or your keypad from view by
using your body or cupping your hand.
