Abstract:

Computer implemented trading cards are disclosed. Trading card software is stored on a removable medium in a copy protected form. The trading card software includes trading card data and an executable computer program. Each removable medium contains trading card data that is specific to a particular individual or character or any other person, place, or thing. The trading card software is interactive. The computer user is able to select one of a number of predetermined displays by selecting interactivity areas on each display. A combination of copy protect schemes are utilized, including non-standard data formatting, encryption and sector modification. After use of the computer program is stopped, trading card data transferred to any storage device of the user's computer system during operation is then removed to prevent storing of the trading card data on any medium other than the removable medium.
