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.
