Abstract

An intelligent router includes means for analyzing content being transferred through it, and means for identifying if the content is proprietary.

Claims

1. An intelligent router comprising:

means for analyzing content being transferred through it; and

12. The intelligent router of claim 9, wherein the tag includes an identifier of what action to take with regard to the content.

13. The intelligent router of claim 9, wherein the tag identifies an owner of the content.

14. The intelligent router of claim 9, wherein the means for generating a tag further includes means for comparing the tag to other tags.

15. The intelligent router of claim 14, wherein the means for comparing the tag to other tags compares the tag to the other tags in a database of tags.

16. The intelligent router of claim 1, wherein the means for analyzing and the means for identifying are embodied in software.

17. The intelligent router of claim 1, wherein the means for analyzing and the means for identifying are embodied in hardware.

18. The intelligent router of claim 1, wherein the means for analyzing and the means for identifying are embodied in firmware.

19. The intelligent router of claim 1, wherein the content includes a music file.

20. The intelligent router of claim 1, wherein the content includes a movie file.

21. The intelligent router of claim 1, wherein the content includes at least a portion of a book.

22. The intelligent router of claim 1, wherein the content includes an image.

24. The intelligent switch of claim 23, further including means for blocking the content from being transferred across the switch.

25. The intelligent switch of claim 23, further including means for modifying the content before transferring it downstream.

26. The intelligent switch of claim 25, wherein the means for modifying the content includes means for adding dead air to a music file.

27. The intelligent switch of claim 25, wherein the means for analyzing the content includes means for generating a tag corresponding to the content.

28. The intelligent switch of claim 27, wherein the tag includes spectral information corresponding to the content.

29. The intelligent switch of claim 27, wherein the tag includes an IP address corresponding to the content.

30. The intelligent switch of claim 27, wherein the tag includes an identifier of what action to take with regard to the content.

31. The intelligent switch of claim 27, wherein the means for generating a tag further includes means for comparing the tag to other tags.

32. The intelligent switch of claim 31, wherein the means for comparing the tag to other tags compares the tag to the other tags in a database of tags.

33. The intelligent switch of claim 23, wherein the means for analyzing and the means for identifying are embodied in software.

34. The intelligent switch of claim 23, wherein the means for analyzing and the means for identifying are embodied in hardware.

35. The intelligent switch of claim 23, wherein the content includes a music file.

36. The intelligent switch of claim 23, wherein the content includes a movie file.

38. The method of claim 37, further including the step of blocking the content from being transferred across the router.

39. The method of claim 37, further including the step of modifying the content before transferring it downstream.
