Abstract

A physical device, the possession of which may provide access to digital media content in a fashion similar to the possession of a DVD providing access to the media content stored thereupon on a suitable DVD player. The possession of the physical device grants access to digital content stored on a remote server using a suitable device such as e.g., a set-top box or media player having Internet connectivity. The physical device provides for convenient and possibly anonymous access to content stored on a remote server and has certain advantages over known techniques for storing rights to access the content.

Claims

1. A system for providing access to conditional access digital media content, the system comprising:

a receiver adapted to receive the conditional access digital media content;

a media player, local to the receiver, configured to play the conditional access digital media content;

a streaming server having access to the conditional access digital media content; and

a secure element configured to provide authorization to access the conditional access digital media content, the secure element comprising a wireless interface configured to operate according to a BLUETOOTH™

standard protocol, wherein;

the receiver is configured to receive the conditional access digital media content from the streaming server via a remote connection;

the secure element is a physical element separate from the receiver, the secure element comprising a memory comprising a prerecorded cryptogram, the cryptogram comprising a unique identifier and a signature for verifying an authenticity of the cryptogram, the unique identifier identifying the conditional access digital media content; and

the receiver comprises a reader including a wireless interface, the receiver being configured to receive the cryptogram from the secure element via the wireless interface, the wireless interface of the reader being configured to operate according to a BLUETOOTH™

standard protocol, the receiver being further configured to provide said access upon authentication of the cryptogram.

2. The system according to claim 1, wherein the secure element comprises a SecureDigital (SD) card and the reader comprises an SD card reader configured to read from the secure element.

3. The system according to claim 1, further comprising:

a touch-sensitive element comprising a further reader configured to read the cryptogram from the secure element, the touch-sensitive element being connected to the receiver; and

wherein the receiver is configured to receive the cryptogram from the touch-sensitive element.

4. The system according to claim 3, wherein the touch-sensitive element is a screen.

5. The system according to claim 4, wherein the screen is a part of the media player.

6. The system according to claim 3, wherein the touch-sensitive element is a table upon which the secure element may be placed.

7. The system according to claim 1, wherein the secure element further comprises a sensor configured to detect an orientation of the secure element, the orientation being used to formulate a command for the receiver.

8. The system according to claim 1, wherein the secure element further comprises a motion detector configured to detect a movement of the secure element, the movement being used to formulate a command for the receiver.

9. The system according to claim 3, wherein the touch-sensitive element is configured to interpret a plurality of secure elements simultaneously placed in closed proximity thereto.

10. The system according to claim 1, wherein the secure element comprises information pertaining to a particular user, said information being used to authenticate a communication between the secure element and the receiver.

11. The system according to claim 1, wherein the secure element is a telephone.

12. A device for providing access to conditional access digital media content, the device comprising:

a receiver adapted to receive the conditional access digital media content from a streaming server via a remote connection, the receiver comprising a reader having a wireless interface and being configured to receive a cryptogram from a secure element via the wireless interface, the wireless interface being configured to operate according to a BLUETOOTH™

standard protocol, and the receiver being further configured to provide said access upon authentication of the cryptogram,

wherein the secure element is a physical element separate from the receiver, the secure element comprising a wireless interface configured to operate according to a BLUETOOTH™

standard protocol and a memory comprising the cryptogram, the cryptogram comprising a unique identifier and a signature for verifying an authenticity of the cryptogram, the unique identifier identifying the conditional access digital media content.

13. The device according to claim 12, wherein the secure element comprises an SecureDigital (SD) card and the reader comprises an SD card reader configured to read from the secure element.

14. The device according to claim 12, wherein the receiver is configured to receive the cryptogram from a touch-sensitive element connected to the receiver.

15. The device according to claim 12, wherein the secure element further comprises a sensor configured to detect an orientation of the secure element, the orientation being used to formulate a command for the receiver.

16. The device according to claim 12, wherein the secure element further comprises a motion detector configured to detect a movement of the secure element, the movement being used to formulate a command for the receiver.

17. The device according to claim 12, wherein the secure element comprises information pertaining to a particular user, said information being used to authenticate a communication between the secure element and the receiver.

18. The device according to claim 12, wherein the secure element is a telephone.
