Abstract: In order to assure the information security of financial ATM, this paper studies and analyzes the keyboard and mouse drivers in Windows operating system, and based on filter driver, designs and implements keyboard and mouse insertion authorization system. The authorization system can detect the insertion of USB or PS/2 interfaced keyboard and mouse into the computer, and keeps the new device disabled before authorized. The final tests demonstrate that the system can be deployed and run on Windows XP and Windows 7 stably and efficiently.

Key words: filter drive, insertion detection, input interception, authorization, round query
