Patent abstract
A board that hides information in a manner that only certain authorized personnel may change the information and other authorized personnel may view the information. This invention accomplishes the foregoing by placing a locked panel of translucent material over certain information written on the board that may only be changed by an authorized individual by opening the lock. A panel of opaque material is placed over the translucent material in a manner that certain information written on the board will be revealed when authorized personnel remove the opaque material or cause the opaque material to be transparent. The translucent material may be removed by activating a switch or entering a code.
