Abstract

Systems and methods for managing digital rights are provided. Remote authentication of a user'"'"'s identity and the user'"'"'s right to receive digital content may be performed in an incontrovertible manner such that the user may not repudiate the transaction. User authentication may be performed in a manner that safeguards the user'"'"'s privacy and may be distributed across multiple communication channels or systems to provide additional assurance that remote users are in fact who they claim to be.

Claims

1. A non-repudiation system for facilitating secure delivery of digital content to a remote user over a network, the system comprising:

a content server adapted to deliver digital content requested by the user to a remote device over the network;

an input device adapted to receive user authentication data uniquely identifying the user; and

an authentication server adapted to receive the user authentication data from the input device for verifying the user'"'"'s identity and determining whether the user is authorized to receive the requested digital content, upon verifying the user'"'"'s identity and determining that the user is authorized to receive the requested digital content, the authentication server adapted to instruct the content server to deliver the requested content to the remote device.

2. The non-repudiation system of claim 1 wherein the authentication server and the content server are operated independently of one another, and wherein the content requested by the user is withheld from the authentication server and the identity of the user is withheld from the content provider.

3. The non-repudiation system of claim 2 further comprising a service unit for charging the user for the digital content delivered to the remote device.

4. The non-repudiation system of claim 3 wherein the authentication server is adapted to forward the user'"'"'s identity to the service unit, and the content server is adapted to forward a transaction identifier associated with the content delivered to the user to the service unit, and the service unit is adapted to prepare a bill charging the user identified by the authentication server for the digital content associated with the transaction identifier provided by the content server.

5. The system of claim 1 wherein the input device adapted to receive user authentication data and the remote device to which the content provider delivers digital content comprise a combined input/terminal device.

6. The system of claim 5 wherein the combined input/terminal device comprises one of a set-top box for receiving a broadband television signal, a mobile telephone;

a wireless email terminal;

or a personal digital assistant.

7. The system of claim 1 wherein the user authentication data uniquely identifying the user comprises a user name and password.

8. The system of claim 1 wherein the user authentication data comprises biometric data.

9. The system of claim 8 wherein the biometric data comprises at least one of a fingerprint scan, or a retinal scan.

10. The system of claim 1 wherein the user authentication data comprises a unique code identifying the user.

11. The system of claim 10 wherein the unique code is provided by a secure token.

12. A system for authenticating a recipient of digital content and recording a transaction in which digital content is delivered to the recipient in a manner that may not be repudiated by the recipient, the system comprising:

an input put device for receiving a unique identifier associated with the recipient;

an authentication server for analyzing the unique identifier to ensure that the recipient is authorized to receive digital content;

a first communication channel for communicating the unique identifier to the authentication server; and

a second communication channel, the authentication server adapted to confirm a request for digital content from the recipient over the second communication channel.

13. The system of claim 12 wherein the input device is adapted to receive biometric data identifying the recipient, the biometric data comprising the unique identifier.

14. The system of claim 13 wherein the input device comprises a fingerprint scanner.

15. The system of claim 13 wherein the input device comprises a retinal scanner.

16. The system of claim 12 wherein the input device is adapted to receive an alphanumeric code identifying the recipient.

17. The system of claim 16 wherein the alphanumeric code comprises a unique combination of a user name and password.

18. The system of claim 16 wherein the alphanumeric code identifying the recipient comprises a sequence generated by a secure token.

19. They system of claim 12 wherein the second communication channel is established between the authentication server and a communication device independent of the input device.

20. The system of claim 12 wherein the second communication channel comprises a wireless link between the authentication server and a mobile communication device.

21. The system of claim 20 wherein the authentication server is adapted to send a text message to the mobile communication device, the text message including a security question having an answer only the recipient would know.

22. A method of recording a network transaction in which digital content requested by a user is delivered to a terminal device designated by the user such that the user'"'"'s request may not be repudiated by the user, the method comprising:

receiving authentication data uniquely identifying the user over a first communication channel;

verifying that the user is authorized to receive the requested digital content based on the received authentication data;

confirming the request with the user over a second communication channel; and

delivering the digital content to the device designated by the user over the network.

23. The method of claim 22 wherein receiving authentication data uniquely identifying the user comprises receiving a user name and password.

24. The method of claim 22 wherein receiving authentication data uniquely identifying the user comprises receiving a correct answer to a security question posed to the user, to which only the user authorized to receive the digital content knows the answer.

25. The method of claim 22 wherein receiving authentication data uniquely identifying the user comprises receiving a security code generated by a secure token.

26. The method of claim 22 wherein receiving authentication data uniquely identifying the user comprises receiving biometric data.

27. The method of claim 26 wherein the biometric data comprises a digitized fingerprint scan.

28. The method of claim 26 wherein biometric data comprises a digitized retinal scan.

29. The method of claim 22 wherein the first communication channel comprises a broadband communication network.

30. The method of claim 22 wherein the first communication channel comprises an TCP/IP packet switched network.

31. The method of claim 22 wherein the second channel comprises a wireless telephone network.

32. The method of claim 31 wherein confirming the request comprises sending an SMS text message to the user over the wireless telephone network requesting confirmation of the request and receiving an SMS text message from the user confirming the request.

33. A network non-repudiation method of authenticating a remote user'"'"'s identity and determining whether the user is authorized to receive digital content requested by the user, the method comprising:

receiving a request for digital content from the user;

requesting a trusted third party to authenticate the user'"'"'s identity and determine whether the user is authorized to receive the requested digital content;

receiving an authentication message from the trusted third party indicating that the user is authorized to received the requested digital content; and

delivering the digital content to a designated device over the network in response to the authentication message.

34. The method of claim 33 further comprising:

the trusted third party forwarding the user'"'"'s identity to a service unit;

forwarding the identity of the requested digital content to the service unit; and

the service unit preparing a bill charging the user for the requested digital content.

35. The method of claim 33 further comprising:

establishing a user payment account with the trusted third party;

communicating a charge amount associated with the requested digital content to the trusted third party;

the trusted third party charging the user payment account for the requested digital content; and

receiving payment for the digital content from the trusted third party.
