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.

Claims

1. An electronic trading card system for use in a processor, said processor having a memory and an apparatus for reading from a removable storage media, said system comprising:

means for loading a copy protected form of a control program and subject data into said memory from said removable storage media;

means for maintaining said control program and said subject data in said copy protected form when resident in said memory; and

means for expunging said control program and said subject data from said memory when said control program ceases executing.

2. A system according to claim 1, having an apparatus for writing to a removable storage media, said system further including:

means for generating a master copy of said control program and said subject data in a non-standard file format;

means for encrypting said master copy having said non-standard file format; and

means for duplicating said master copy onto said removable storage media to provide portability and maintain authenticity of said control program and said subject data.

3. A system according to claim 2, wherein said means for generating includes:

means for altering at least one sector of said master copy of an otherwise standard sector file format for said removable storage media.

4. A system according to claim 2, wherein said copy protection means further includes:

means for compressing at least one said master copy onto said removable storage media.

5. A system according to claim 1, wherein said means for loading includes:

means for decompressing said copy protected form of said control program and said subject data.

6. A system according to claim 1, said processor further having a display device for producing output in at least one form selected from the group consisting of:

audio, fixed visual, and moving visual, and a user input device for accepting a user input command in at least one input form selected from the group consisting of;

typing, pointing, touching, vocalizing, and neural-electrical directing, said system further including;

means, responsive to said means for loading, for relinquishing control of said processor to said control program to construct a subject display from said subject data by way of said display device, wherein said subject display includes at least one subject selected from the group consisting of;

a person, a place, and a thing; and

means, responsive to said user input command, for generating at least one highlight of said subject display by way of said display device.

7. A system according to claim 6, wherein said subject display includes:

means for generating at least one fixed visual display perspective selected from the group consisting of;

a front perspective, and a back perspective.

8. An electronic trading card system on a processor, said processor having an apparatus for writing to a removable storage media, said system comprising:

means for generating a master copy of a control program and subject data in a non-standard file format, wherein said non-standard file format includes altering at least one sector of said master copy of an otherwise standard sector file format for said removable storage media;

means for encrypting said master copy having said non-standard file format;

means for compressing at least one said master copy onto said removable storage media to provide portability and maintain authenticity of each of said control program and said subject data.

9. A method for using an electronic trading card system with a processor, said processor having a memory, and an apparatus for reading from a removable storage media, said method comprising the steps of:

loading a copy protected form of a control program and subject data into said memory from said removable storage media;

maintaining said control program and said subject data in said copy protected form when resident in said memory; and

expunging said control program and said subject data from said memory when said control program ceases executing.

10. A method according to claim 9, having an apparatus for writing to a removable storage media, said method including the steps of:

generating a master copy of said control program and said subject data in a non-standard file format;

encrypting said master copy having said non-standard file format; and

duplicating said master copy onto said removable storage media to provide portability and maintain authenticity of said control program and said subject data.

11. A method according to claim 10, wherein said generating step includes:

altering at least one sector of said master copy of an otherwise standard sector file format for said removable storage media.

12. A method according to claim 10, wherein said duplicating step includes:

compressing at least one said master copy onto said removable storage media.

13. A method according to claim 9, wherein said loading step includes:

decompressing said copy protected form of said control program and said subject data.

14. A method according to claim 9, said processor further having a display device for producing output in at least one form selected from the group consisting of:

audio, fixed visual, and moving visual, and a user input device for accepting a user input command in at least one input form selected from the group consisting of;

typing, pointing, touching, vocalizing, and neural-electrical directing, said system further including;

relinquishing control of said processor to said control program to construct a subject display from said subject data by way of said display device, in response to said loading step, wherein said subject display includes at least one subject selected from the group consisting of;

a person, a place, and a thing; and

generating at least one highlight of said subject display by way of said display device, in response to said user input command.

15. A method according to claim 14, wherein said generating step includes:

generating at least one fixed visual display perspective selected from the group consisting of;

a front perspective, and a back perspective.

16. A method for preparing an electronic trading card system on a processor, said processor having an apparatus for writing to a removable storage media, said system comprising:

generating a master copy of a control program and subject data in a non-standard file format, wherein said non-standard file format includes altering at least one sector of said master copy of an otherwise standard sector file format for said removable storage media;

encrypting said master copy having said non-standard file format; and

compressing at least one said master copy onto said removable storage media to provide portability and maintain authenticity of each of said control program and said subject data.
