Software Controlled Locking for Media-based Input Devices

Disclosed is a system to automatically lock media-based input devices to prevent unauthorized access to these devices. The disclosed system solves the following two problems:

Media theft - When a computer is locked using the operating system's "Lock Computer"

function (for example, Ctrl-Alt-Delete and then selecting Lock Computer in Windows 2000) or letting the password enabled screen saver to kick in, media-based input devices such as disk drives, CD-ROM/DVD drives, etc. can still be opened and any media they may contained can be taken.

Harmful media being inserted - When physical access to the hardware is possible (even

for a few seconds), a diskette inserted into a computers disk drive could result in theft of significant intellectual property the next time the computer is rebooted without the computer's owner even suspecting that his/her computer has been attacked.

The system solves the problems by doing the following two things:

Building lock enable media-based input devices. Different types of input devices will have

different types of locking mechanisms. For example, a CD-ROM drive locking mechanism may be a simple disablement of the eject button. A disk drive may require disabling the eject button and a rod being extended through the area that the diskette occupies thus blocking it. The mechanism should take into account the status of the device namely, does it contain media, is it open or closed,...
