Explanation:
Looking at information on a computer screen without the computer user’s knowledge is known as 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.
