Abstract

System and method for transmitting and protecting media data set in a data communication medium. The invention provides encryption of media data and authorization prior to the media data being accessible on the end-user device. A Set Top Box provides for storage of media data downloaded through an access point, with security structures built in to the downloaded media data. The Set Top Box sends media data through a network to end-user devices that are recognized as authorized end-user devices. The system may further include limitations on the availability of the media data at the end-user device based upon wired, wireless, physics-based and location based security.

Claims

1. A method of providing encrypted data content to an end-user device, said method comprising the steps of:

connecting an end-user device to an access point, said access point communicatively connected to a master transaction manager;

generating an end-user device profile that comprises device type, media formats and attributes supported by an end-user device;

authenticating an end-user device through the said access point to an end-user access list stored on a master transaction manager;

receiving and processing a request for data content by an end-user device;

exporting data content requested by an end-user from a content provider to a set top box wherein said set top box is communicatively connected to said access point and said set top box further comprises a media storage device;

adding exported data content to a set top box data content library;

encrypting exported data content; and

formatting exported data content to comply with said end-user device profile.

2. The method of claim 1 wherein said encrypting is performed in accordance with encrypting parameters stored within said access point.

3. The method of claim 1 further comprising the step of communicating encrypted data content to an end-user device.

4. The method of claim 1 wherein data content is formatted for a end-user device prior to exporting said data content to said set top box.

5. The method of claim 1 wherein said data content located within the set top box is stored as a master media file and the master media file is transcoded to an end-user device compatible format within the set top box at the time that said data content is communicated to said end-user device.

6. The method of claim 1 wherein the set top box is an electronic device.

7. The method of claim 1 wherein the set top box comprises software installed on an electronic device.

8. The method of claim 1 wherein said end-user device profile is generated by and stored within said access point.

9. The method of claim 1 wherein said access point further comprises a data content catalog comprising a list of available data content.

10. The method of claim 9 wherein the set top box further comprises means for browsing the data content catalog.

11. The method of claim 1 wherein said data content located within the set top box is stored as a master media file and the master media file is encrypted by the set top box at the time that said data content is communicated to said end-user device.

12. The method of claim 1 wherein said step of encrypting further comprises choosing encryption from the group comprising location-based security restrictions and time-to-live security restrictions.

13. A set top box for providing encrypted data content to an end-user device, said set top box comprising:

An access point comprising means for authenticating an end-user device to a content provider and processing searches and requests for data content between an end-user device and a content provider;

Data storage means;

Communication means to connect said access point and said content provider;

Means for encrypting data content stored on said data storage means; and

Means for communicating data content between an end-user device and said set top box.

14. The set top box of claim 13 wherein the set top box further comprises a master security service communicatively connected to said access point, said master security service comprising means for authenticating an end-user device to a content provider.

15. The set top box of claim 13 wherein said set top box further comprises means to generate a browsable content catalog of data content located on said data storage means.

16. The set top box of claim 13 wherein said means for encrypting data content stored on said data storage means further comprises means for restricting playback of data content, said means for restricting playback of data content is chosen from the group comprising location-based security restrictions or time-to-live security restrictions.

17. The set top box of claim 13 further comprising means for receiving updates and modifications to said means for encrypting data content.

18. The set top box of claim 13 wherein said set top box further comprises means for detecting end-user device profile information.

19. The set top box of claim 18 wherein end-user device profile information is chosen from a group consisting of end-user device type, media formats supported by the end-user device, and media quality attributes comprising file size, resolution, and compression factors.

20. The set top box of claim 13 wherein said data content communicated between said end-user device and said set top box consists of data configured in accordance with an end-user device profile.

21. A set top box for providing encrypted data content to an end-user device, said set top box comprising:

An access point comprising means for authenticating an end-user device to a content provider and processing searches and requests for data content between an end-user device and a content provider;

Means for detecting end-user device profile information chosen from a group comprising end-user device type, media formats supported by the end-user device, and media quality attributes comprising file size, resolution, and compression factors;

Data storage means;

Communication means to connect said access point and said content provider;

Means for encrypting data content stored on said data storage means, said means for encrypting data content comprising means for restricting playback of data content;

Means for receiving updates and modifications to said means for encrypting data content;

Means for communicating data content between said end-user device and said set top box;

A master security service communicatively connected to said access point, said master security service comprising means for authenticating an end-user device to a content provider; and

Means for generating a browsable content catalog of data content located on said data storage means.

22. The set top box of claim 21 wherein said means for restricting playback of data content is chosen from the group comprising location-based security and time-to-live security restrictions.

23. The set top box of claim 21 wherein said data content communicated between said end-user device and said set top box comprises data configured in accordance with end-user device profile information.
