Abstract

An embodiment of the invention provides a method including accessing a portal pursuant to instructions from a digital media device and identifying the digital media device to the portal to enable the portal to obtain a security code. Information having the security code is received; and, it is confirmed that the security code corresponds to a security key stored in the digital media device. The information is provided to a secure application environment in the digital media device if the security code corresponds to the security key. A copy of the security key is sent to a clearinghouse; and, the security code is received from the clearinghouse. The security code is sent to a provider of the information if the information satisfies a predetermined criteria.

Claims

1. A method, comprising:

requesting by a digital media device information from a portal via a network, the digital media device being implemented on a system on a chip and having an embedded security key and one or more secure application environments therein;

transmitting a device identification number from the digital media device to the portal, said portal being assigned to a secure application environment on the digital media device;

transmitting the device identification number to a clearinghouse, said clearinghouse determining a security key associated with the device identification number and creating a security code associated with the security key;

transmitting the security code from the clearinghouse to the portal, said portal embedding the security code into the requested information;

sending the requested information with the embedded security code to the secure application environment, said secure application environment determining whether the embedded security code corresponds to the embedded security key; and

performing a requested function using the information at the digital media device by the secure application environment when the security code embedded into the requested information corresponds to the embedded security key.

2. The method according to claim 1, wherein when the security code embedded into the requested information does not correspond to the embedded security key, the secure application environment ignores the requested information.

3. The method according to claim 1, wherein the clearinghouse receives a copy of the security key from a manufacturer of the digital media device.

4. The method according to claim 1, wherein an entity operating the clearinghouse is different from an entity providing the requested information.

5. The method according to claim 1, wherein the digital media device is connected to a display unit and the network is the internet.

6. The method according to claim 5, wherein the display unit comprises a television.

7. The method according to claim 1, wherein the embedded key is on an integrated circuit of the digital media device.

8. The method according to claim 1, wherein the digital media device comprises a plurality of secure application environments, each secure application environment being connected to only one portal.

9. The method according to claim 1, wherein the requested information comprises movies, songs, video games, photographs, animation, text, graphics, or web pages.

10. The method according to claim 1, further comprising displaying the requested information to a user via a television.

11. A computer program product for performing a method, the computer program product comprising:

a non-transitory computer readable storage medium;

first program instructions to request by a digital media device information from a portal via a network, the digital media device being implemented on a system on a chip and having an embedded security key and one or more secure application environments therein;

second program instructions to transmit a device identification number from the digital media device to the portal, said portal being assigned to a secure application environment on the digital media device;

third program instructions transmit the device identification number to a clearinghouse;

fourth program instructions to receive a security code associated with the security key from the clearinghouse to the portal, said portal embedding the security code into the requested information;

fifth program instructions to send the requested information with the embedded security code to the secure application environment; and

sixth program instructions to determine whether the embedded security code corresponds to the security key embedded in the digital media device,

wherein the first program instructions, the second program instructions, the third program instructions, the fourth program instructions, the fifth program instructions, and the sixth program instructions are stored on the non-transitory computer readable storage medium; and

performing a requested function using the information at the digital media device by the secure application environment when the security code embedded into the requested information corresponds to the embedded security key.

12. The computer program product according to claim 11, wherein the digital media device is connected to a display unit and the network is the internet.

13. The computer program product according to claim 12, wherein the display unit comprises a television.

14. The computer program product according to claim 11, wherein the embedded key is on an integrated circuit of the digital media device.
