Abstract
A hidden image game piece is formed on a transparent or translucent substrate which is part of an optical disc (e.g., a CD or DVD). The hidden image can be used to contain a “key” which is required to gain access to the data contained on the optical disc, thereby aiding in the prevention of that type of piracy of the content of the optical disc which could be accomplished by a simple disc-to-disc copy.
