Abstract

A system for effecting a transaction includes a head-end (3), a communications network (4), and a receiver (1), capable of receiving digital information, including content data from the head-end (3) through the network (4), and of making the content data available to a user on a display device (2). The receiver (1) further includes an interface (7) to a subscriber secure device (6). The system has the capability to create a transaction token, incorporating a first code uniquely identifying the subscriber secure device (6). The receiver (1) is programmed to make the first code available on the display device (2). The system further includes a terminal (9,10;12) for creating a transaction token, including an interface (10) to a client secure device (11;13). The terminal (9-12) includes a user interface for entering the first code, and is arranged to create the transaction token from the entered first code in co-operation with the client secure device (11;13).

Claims

1. A system for effecting a transaction, including a head-end, a communications network, and a receiver, capable of receiving digital information, including content data from the head-end through the network, and of making the content data available to a user on a display device, which receiver further includes an interface to a subscriber secure device, the system having the capability to create a transaction token, incorporating a first code uniquely identifying the subscriber secure device, wherein the receiver is programmed to make the first code available on the display device, and the system further includes a terminal for creating a transaction token, including an interface to a client secure device, wherein the terminal includes a user interface for entering the first code, and is arranged to create the transaction token from the entered first code in co-operation with the client secure device.

2. A method of enabling a transaction, in a system including a head-end, a communications network, and a receiver, capable of receiving digital information, including content data, from the head-end through the network and of making the content data available to a user on a display device, which receiver further includes an interface to a subscriber secure device, wherein a first code for creating a transaction token, uniquely identifying the subscriber secure device, is made available to the user on the display device.

3. A method according to claim 2, wherein a second code, identifying a product to be ordered, and included in the content data, is made available to the user on the display device.

4. A computer program having the potential, when run on a system, including a receiver and a subscriber secure device, connected to the receiver through an interface, to enable the system to execute a method according to claim 2.

5. A system, including a receiver, capable of receiving digital information, including content data, from a head-end through a network, and a subscriber secure device, connected to the receiver through an interface, wherein the system is arranged to carry out a method according to claim 2.

6. A subscriber secure device, suitable for use in a system according to claim 5, wherein the subscriber secure device includes a further identification code, and is arranged to calculate the first code by encrypting the further identification code.

7. A terminal for creating a transaction token, including an interface to a client secure device, and arranged to create a transaction token incorporating a first code, identifying a subscriber secure device, wherein the terminal includes a user interface for entering the first code, and is arranged to create the transaction token from the entered first code in co-operation with the client secure device.

8. A terminal according to claim 7, including a user interface for entering a second code, identifying a product to be bought, wherein the terminal is arranged to incorporate the second code in the transaction token in co-operation with the client secure device.

9. A terminal according to claim 7, wherein the terminal is arranged to include a digital signature with the transaction token in co-operation with the client secure device.

10. A terminal according to claim 9, wherein the terminal includes a user interface for entering a personal identification code, and is arranged to generate the digital signature using the personal identification code in co-operation with the client secure device.

11. A terminal according to claim 7, wherein the terminal includes a user interface for entering further details of the transaction, and is arranged to incorporate the entered details in the token in co-operation with the client secure device.

12. A terminal according to claim 7, arranged to establish a communications link with an arbitrator system, and to transfer the token through the communications link to the arbitrator system.

13. A terminal according to claim 12, wherein the terminal is arranged to receive a confirmation of the transaction from the arbitrator system, and has the capability of indicating receipt of the confirmation to the user.

14. A client secure device, suitable for use in a terminal according to claim 7, and arranged to create at least part of the transaction token.

15. A computer program having the potential, when run on a terminal including a client secure device and a user interface, to provide the system including the terminal and the client secure device with the functionality of a terminal according to claim 7.
