Shoulder surfing and Prevention
Shoulder surfing is a technique wherein someone looks over you shoulder, to get information about what you are writing or typing. Shoulder surfing is an effective way to get information in crowded places, such as cyber caffe, because it's relatively easy to stand next to someone and watch as they fill out a form, enter e-Banking User ID and Password, or enter a PIN number at an ATM machine. Shoulder surfing can also be done long distance with the aid of binoculars or other vision-enhancing devices.
To prevent shoulder surfing
It is recommended that you shield paperwork or your keyboard from view by using your body or cupping your hand. So watch out around you before you use e-Banking from crowded place.
