FlatPanel Display Security System

   Abstract

   This invention describes a solution that helps to
deter flatpanel display theft.  The invention also allows a user to
uniquely identify their flatpanel display if it is recovered from a
robbery even if the serial numbers are physically removed from the
display.

   Problem

   Flatpanel displays used in computers are often prone to
theft.  This is due to their high cost and the fact that they are
easily disconnected from a computer.  Also, their small size
(compared to a convential CRT type displays) allows them to be
easily concealed in a handbag.

   Solution

   Nearly every flatpanel display contains a number of
push-buttons on their front panel.  These buttons normally allow for
adjustment of many of the display's features such as size and
position through an on-screen menu.  The flatpanels that contain
these push-buttons also contain a microprocessor that monitors the
inputs of the push-buttons and executes the appropriate action.

   The idea of this invention is to add a new function
to the push-buttons and the microprocessor contained in the display.
First, the push-buttons on the frontpanel of the display are
numbered.  For example, if there are 6 buttons, they are numbered 1-6
(ref. Diagram 1).  Also a label titled "Security" could be added to
the frontpanel of the display to indicate the function of the
numbers.

   Next, a new menu option called security is added to the
on-screen menu for the display (ref. Diagram 2).  Whenever this menu
option is selected the user is prompted to enter a sequence of
numbers from the front panel pushbuttons.  This sequence of numbers
is then saved in nonvolatile memory (e.g. -FLASH) inside the display
so that it is not lost when power is removed from the display.

   This sequence of numbers is effectively the password for
the display.  Anytime the display is powered on after the password
is set, the user must enter the correct sequence of numbers for the
display t...
