Abstract

A method for detecting against unauthorized transmission of digital works comprises the steps of maintaining a registry of information permitting identification of digital copyrighted works, monitoring a network for transmission of at least one packet-based digital signal, extracting at least one feature from the at least one digital signal, comparing the extracted at least one feature with registry information and applying business rules based on the comparison result.

Claims

1. A digital works identification system comprising:

a first memory for storing information permitting identification of digital works;

a digital input receiver for receiving at least one packet-based digital signal transmitted over a network;

a second memory for storing at least one portion of the at least one packet-based digital signal; and

at least one processor for obtaining at least one feature from the at least one digital signal and comparing the at least one feature with the stored identifying information.

2. The method of claim 1, wherein the system is intended to protect copyrighted works.

3. The method of claim 1, wherein the system is intended to identify new digital works.

4. The system of claim 1, wherein the at least one feature includes data sufficient to generate a content-based fingerprint from the content of the at least one digital signal.

5. The system of claim 1, wherein the at least one feature includes feature vectors generated from the content of the at least one digital signal.

6. The system of claim 1, wherein the at least one digital signal comprises one or more of digital audio information, digital video information, digital representation of text, software, and digital image information.

7. The system of claim 1, wherein the at least one processor identifies digital works carried by the at least one packet-based digital signal.

8. The system of claim 1, wherein the at least one packet-based digital signal is characterized by at least one of:

a source address;

or a destination address.

9. The system of claim 1, further comprising a third memory for recording the identified transmissions.

10. The system of claim 9, wherein the third memory further includes a transaction database.

11. The system of claim 9, further comprising a report generator for generating reports on transmissions carried by the at least one packet-based digital signal.

12. The system of claim 8, further comprising a transaction request broker for identifying whether a destination address is authorized to receive the content of the at least one digital signal.

13. The system of claim 12, further comprising means for disabling transmission of at least a portion of the at least one packet-based digital signal if the destination address is not authorized to receive the content of the at least one digital signal.

14. The system of claim 8, further comprising a transaction request broker for identifying whether a source address is authorized to transmit the content of the at least one digital signal.

15. The system of claim 14, further comprising means for disabling transmission of at least a portion of the at least one packet-based digital signal if the source address is not authorized to transmit the content of the at least one digital signal.

16. The system of claim 8, further comprising a message generator for sending a message to the source address or destination address upon detection of an identified transmission.

17. The system of claim 16, wherein the message directs a destination address to a commercial site where authorization to obtain the desired content may be purchased.

18. The system of claim 8, wherein other content is inserted into the transmission.

19. The system of claim 8, wherein other content is substituted into the transmission.

20. The system of claim 1, wherein the at least one processor includes:

a content type recognizer for identifying the file type of a packet-based digital signal.

21. The system of claim 1, wherein the at least one processor includes:

a content identifier for identifying the content of a packet-based digital signal.
