In a computer security context, shoulder surfing is a commonly used technique of stealing information simply by using observation, such as looking over someone’s shoulder. Most people are careless and ignorant of their surroundings while in public places such as Wi-Fi hotspots, airplanes and airport lounges. By observing what you are browsing, such as business plans, client details or any sensitive data, that information can easily be stolen or used against you.
