CLAIM OF PRIORITY This application is a continuation of U.S. application Ser. No. 10/320,916 filed Dec. 16, 2002, which issued as U.S. Pat. No. 6,993,137 on Jan. 31, 2006, and claims the priority benefit of International Application No. PCT/US01/19271, filed on Jun. 15, 2001, and of U.S. Provisional Application No. 60/212,215, filed Jun. 16, 2000, each of which is incorporated herein by reference.
TECHNICAL FIELD The present application relates generally to the field of network communications and, more specifically, to a method and system to secure content for distribution and delivery.
BACKGROUND The proliferation of networks, and the widespread acceptance of the Internet as a communication and distribution channel in particular, have presented a number of opportunities for pay media content distribution. Specifically, broadband Internet Protocol (IP) networking and satellite technologies have provided a number of new opportunities for publishing and media content distribution worldwide. The ability of networks to support resource-intensive media, such as streaming media multicasting, is growing rapidly as satellite and broadband IP technologies allow content and service providers to distribute high-quality video to millions of subscribers simultaneously.
DETAILED DESCRIPTION In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details and that these specific details are exemplary.
Field Description Unique Key MerchantId Merchant Received Type Subscription/PPV CaAgentId (0 if subscription) Transaction Overview�Conditional Access Agent 28 A conditional access agent 28 operates as a secure gatekeeper to actual content provided via a content distributor 20. A conditional access agent 28, in one exemplary embodiment of embodiment, is co-located with a local content server 40 to �police� local subscriber accesses to protected content stored on that media server.
By checking that both the delivery address of a user authentication or copy-protected device, and the source IP address of a content request are located within an authorized geographic location, the present invention seeks to prevent a user from utilizing a secure device, properly authorized, within an unauthorized geographic location. Specifically, the IP source address check decreases the ability of a fraudulent user to access content from a �blocked� geographic location. Content and keys are only delivered if a user has access to a user authentication and/or copy-protected device that is not officially distributed to any blocked region, and the source IP address of the content requester is not mapped to any blocked region.
FIG. 27 is a diagrammatic representation of a machine in the form of computer system 700 within which software, in the form of a series of machine-readable instructions, for performing any one of the methods discussed above may be executed. The computer system 700 includes a processor 702, a main memory 704 and a static memory 706, which communicate via a bus 708. The computer system 700 is further shown to include a video display unit 710 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 700 also includes an alphanumeric input device 712 (e.g., a keyboard), a cursor control device 714 (e.g., a mouse), a disk drive unit 716, a signal generation device 718 (e.g., a speaker) and a network interface device 720. The disk drive unit 716 accommodates a machine-readable medium 722 on which software 724 embodying any one of the methods described above is stored. The software 724 is shown to also reside, completely or at least partially, within the main memory 704 and/or within the processor 702. The software 724 may furthermore be transmitted or received by the network interface device 720. For the purposes of the present specification, the term �machine-readable medium� shall be taken to include any medium that is capable of storing or encoding a sequence of instructions for execution by a machine, such as the computer system 700, and that causes the machine to perform the methods of the present invention. The term �machine-readable medium� shall be taken to include, but not be limited to, solid-state memories, and optical and magnetic disks, and carrier wave signals.
