Abstract

A local content server system (LCS) for creating a secure environment for digital content is disclosed, which system comprises: a communications port in communication for connecting the LCS via a network to at least one Secure Electronic Content Distributor (SECD), which SECD is capable of storing a plurality of data sets, is capable of receiving a request to transfer at least one content data set, and is capable of transmitting the at least one content data set in a secured transmission; a rewritable storage medium whereby content received from outside the LCS may be stored and retrieved; a domain processor that imposes rules and procedures for content being transferred between the LCS and devices outside the LCS; and a programmable address module which can be programmed with an identification code uniquely associated with the LCS. The LCS is provided with rules and procedures for accepting and transmitting content data.

Claims

1. A local content server system (LCS) for providing conditional access to content, said LCS comprising:

an LCS address module storing an LCS identification code;

an LCS storage unit for storing content in encrypted or scrambled digital form in non-transient memory;

an LCS communications port designed to receive content in the form of digital data;

an LCS domain processor for processing digital data, wherein said LCS domain processor is configured to;

(1) determine if encrypted or scrambled first content received by said LCS communications port contains indicia indicating authenticity and store said first content in said LCS storage unit in encrypted or scrambled digital form when said LCS domain processor determines that said encrypted or scrambled first content received by said LCS communications port contains indicia indicating authenticity;

(2) determine if encrypted or scrambled first content received by said LCS communications port contains indicia indicating lack of authenticity and to not store said first content in said LCS storage unit when said LCS domain processor determines that said encrypted or scrambled first content received by said LCS communications port contains indicia indicating lack of authenticity; and

(3) determine if encrypted or scrambled first content received by said LCS communications port contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity and degrade said first content and store the degraded first content in said LCS storage unit when said LCS domain processor determines that said first content contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity.

2. The LCS of claim 1 wherein said LCS domain processor is configured to use a watermark extractor for determining if said encrypted or scrambled first content contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity.

3. The LCS of claim 1 wherein said domain processor is configured to determine if a Satellite Unit (SU) is authorized to communicate with said LCS.

4. The LCS of claim 1 wherein said first content is perceptually based information.

5. The LCS of claim 1 wherein said first content is value-added information.

6. The LCS of claim 1 wherein said encrypted or scrambled first content is encrypted.

7. The LCS of claim 1 wherein said encrypted or scrambled first content is scrambled.

8. A method for using a local content server system (LCS) for providing conditional access to content, said LCS comprising an LCS address module storing an LCS identification code;

an LCS storage unit for storing content in encrypted or scrambled digital form in non-transient memory;

an LCS communications port designed to receive content in the form of digital data;

an LCS domain processor for processing digital data;

where said method comprises;

said LCS domain processor determining (1) if encrypted or scrambled first content received by said LCS communications port contains indicia indicating authenticity and storing said first content in said LCS storage unit in an encrypted or scrambled form when said LCS domain processor determines that said encrypted or scramble first content contains indicia indicating authenticity;

(2) if encrypted or scrambled first content received by said LCS communications port contains indicia indicating lack of authenticity and not storing said first content in said LCS storage unit when said LCS domain processor determines that said encrypted or scrambled first content contains indicia indicating lack of authenticity; and

(3) if encrypted or scrambled first content received by said LCS communications port contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity and degrading and storing the degraded first content in said LCS storage unit when said LCS domain processor determines that said encrypted or scrambled first content contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity.

9. The method of claim 8 wherein said LCS domain processor uses a watermark extractor for determining if said encrypted or scrambled first content contains neither one of indicia indicating authenticity and indicia indicating lack of authenticity.

10. The method of claim 8 wherein said domain processor determines if a Satellite Unit (SU) is authorized to communicate with said LCS.

11. The method of claim 8 wherein said first content is perceptually based information.

12. The method of claim 8 further comprising said LCS switching from employing a first algorithm to employing a second algorithm to perform the step of said LCS domain processor determining.

13. The method of claim 12 further comprising updating software in said LCS so that said LCS switches from employing said first algorithm to employing said second algorithm to perform the step of said LCS domain processor determining.

14. The method of claim 12 further comprising said LCS switching from employing said second algorithm to employing a third algorithm to perform the step of said LCS domain processor determining.

15. The method of claim 14 further comprising updating software in said LCS so that said LCS switches from employing said second algorithm to employing said third algorithm to perform the step of said LCS domain processor determining.

16. The method of claim 8 wherein said LCS comprises control access software, and said LCS domain processor executes said control access software, to thereby define an LCS domain.

17. The method of claim 8 wherein said encrypted or scrambled first content is encrypted.

18. The method of claim 8 wherein said encrypted or scrambled first content is scrambled.
