Keylogging, also known as Keystroke logging, is a method of logging tracking or logging the key pressed on a keyboard. The softwares employed for this purpose are called Keyloggers. The technique of keylogging is usually used to spy on a person by recording what keys a person pressed on the keyboard. Keylogger softwares generate text files containing the keys that have been pressed.
Most of the keyloggers are designed to work in stealth mode, that means no window will be shown on the monitor and the person being tracked will not realize that his keystrokes are being logged in the background. Keyloggers are usually activated by pressing a combination of secret keys, which makes the invisible keylogger window visible. Some keyloggers also have the feature of sending the log file to a specified email address in the background, allowing to spy on somebody from remote.
Hardware-based keyloggers are also available, but software-based keyloggers are more popular.
