Abstract

Systems and methods that prevent unauthorized access in a communications network are provided. In one embodiment, a system that prevents unauthorized access to a network device may include, for example, a network device and a headend. The headend may be coupled to a communications network. The network device may be deployed in a home environment and may be communicatively coupled to the communications network via the headend. The headend may be adapted, for example, to determine whether a request to access the network device is authorized.

Claims

1. A system that prevents unauthorized access, comprising:

a network device;

a cable television headend; and

a communications network,

wherein the cable television headed is communicatively coupled to the communications network, wherein the cable television headend determines whether a request to access the network device is authorized, wherein the network device includes at least one of a computer, a storage device, set-top box circuitry, a television, a display and a remote control, wherein the network device is deployed in a home environment and is communicatively coupled to the communications network through the cable television headend, and wherein the cable television headend determines whether a particular service provider, which is seeking access to the network device, is authorized to send data to the network device.

2. The system according to claim 1, wherein the cable television headend performs one or more of the following:

Internet protocol registration, identification registration and digital rights management.

3. The system according to claim 1, wherein the cable television headend performs one or more of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and tracking.

4. The system according to claim 1, wherein the cable television headend processes one or more of the following:

a device identification, an IP address, a digital certificate and a key.

5. The system according to claim 1, wherein the cable television headend stores one or more of the following:

a device identification, a public key, a hashing signature and an IP address.

6. The system according to claim 1, wherein the cable television headend prevents unauthorized data from reaching the network device.

7. The system according to claim 1, wherein the personal media is received by the cable television headend from the communications network.

8. The system according to claim 1, wherein the cable television headend employs one or more of the following:

authentication techniques, encryption techniques and decryption techniques.

9. The system according to claim 1, wherein the cable television headend facilitates pushing a file residing in an authorized device to the network device or to a storage device communicatively coupled to the network device.

10. The system according to claim 9, wherein the pushed file is transported through the cable television headend to the network device or to the storage device communicatively coupled to the network device.

11. The system according to claim 1, wherein the communications network comprises a packet-based communications network.

12. The system according to claim 1, wherein the cable television headend provides at least some of the functionality of a media exchange server.

13. The system according to claim 1, wherein the cable television headend performs one or more of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and tracking.

14. The system according to claim 1, wherein the cable television headend processes or stores one or more of the following:

a device identification, an Internet protocol address, a digital certificate, a key and a hashing signature.

15. The system according to claim 1, wherein the cable television headend is deployed outside of the home environment of the network device.

16. A system that prevents unauthorized access, comprising:

a network device;

a cable television headend; and

a communications network,

wherein the cable television headed is communicatively coupled to the communications network, wherein the cable television headend determines whether a request to access the network device is authorized, wherein the network device is deployed in a home and is communicatively coupled to the communications network through the cable television headend, and wherein the cable television headend determines whether a particular service provider, which is seeking access to the network device, is authorized to send data to the network device, wherein the cable television headend is not deployed in the home.

17. The system according to claim 16, wherein the cable television headend performs one or more of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and tracking.

18. A system that prevents unauthorized access, comprising:

one or more network devices in a home network;

a cable television headend; and

a communications network,

wherein the cable television headed is communicatively disposed between the communications network and the home network, wherein the cable television headend determines whether a request to access the one or more network devices is authorized, wherein the one or more network devices are deployed in a the home network and are communicatively coupled to the communications network through the cable television headend, and wherein the cable television headend determines whether a particular service provider, which is seeking access to the one or more network devices, is authorized to send data to the one or more network devices, wherein the cable television headend is not part of the home network.

19. The system according to claim 18, wherein the cable television headend performs one or more of the following:

Internet protocol registration, identification registration and digital rights management.

20. The system according to claim 18, wherein the cable television headend performs one or more of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and tracking.
