A Keystroke Logger Detection Using Keyboard-Input-Related API Monitoring

Recently, keystroke logger is becoming a major security issue. Keystroke logger is a malware that steels user´s keyboard input without his or her informed consent. Keyboard input related Application Programming Interfaces (APIs) are commonly used by keystroke logger software to illegally record users´ keystrokes. This paper proposes a security scheme to protect against keystroke loggers by using a DLL to detect illegal use of APIs. By executing a program with the DLL, we can check whether the program includes any of these keyboard-input-related APIs or not.
