Peeping attack is becoming an issue in the present day world with peeping toms looking over someone's shoulder while the user is keying in personal data into a computer or punching password at an ATM kiosk. Also there could be the presence of any external device, which may be placed in order to trap the user and obtain valuable information, such as, their passwords or ATM card pin numbers, while the user types through. This form of attack is commonly known as shoulder surfing attack. Shoulder surfing is a critical way to know any information, related to a person, who is doing any work in a system.
