Abstract

A secure access system for controlling access to a plurality of items. The system includes a first IC card reader adapted to receive a first IC card which includes first control information, a second IC card reader adapted to receive a second IC card which includes second control information, and a control integrator receiving the first control information and the second control information and allowing access to a first one of the plurality of items based, at least in part, on both the first control information and said second control information, and to a second one of the plurality of items based, at least in part, on the first control information, without regard to the second control information.

Claims

1. Secure access apparatus for controlling access to a plurality of items, the apparatus comprising:

a first IC card reader adapted to receive a first IC card comprising first control information;

a second IC card reader adapted to receive a second IC card comprising second control information; and

a control integrator receiving said first control information and said second control information and operative to allow access to a first one of said plurality of items based, at least in part, on both said first control information and said second control information,

wherein said control integrator also allows access to a second one of said plurality of items based, at least in part, on said first control information, without regard to said second control information.

2. Apparatus according to claim 1 and wherein said second control information comprises parental control information.

3. Apparatus according to claim 1 and wherein said plurality of items comprises a plurality of television programs.

4. Apparatus according to claim 1 and wherein said plurality of items comprises a plurality of digital messages.

5. Apparatus according to claim 4 and wherein at least one of said plurality of digital messages comprises a computer program.

6. Apparatus according to claim 4 and wherein at least one of said plurality of digital messages comprises data.

7. Apparatus according to claim 6 and wherein said at least one of said plurality of digital messages comprises multimedia data.

8. Apparatus according to claim 1 and wherein said second control information comprises payment information.

9. A method for controlling access to a plurality of items, the method comprising:

receiving a first IC card comprising first control information;

receiving a second IC card comprising second control information; and

allowing access to a first one of said plurality of items based, at least in part, on both said first control information and said second control information,

wherein said step of allowing access comprises allowing access to a second one of said plurality of items based, at least in part on said first control information, without regard to said second control information.

10. A method according to claim 9 and wherein said second control information comprises parental control information.

11. A method according to claim 9 and wherein said plurality of items comprises a plurality of television programs.

12. A method according to claim 9 and wherein said plurality of items comprises a plurality of digital messages.

13. A method according to claim 12 and wherein at least one of said plurality of digital messages comprises a computer program.

14. A method according to claim 12 and wherein at least one of said plurality of digital messages comprises data.

15. A method according to claim 14 and wherein said at least one of said plurality of digital messages comprises multimedia data.

16. A method according to claim 9 and wherein said second control information comprises payment information.
