1. A method comprising:
- identifying, by a processor, a transmission associated with a digital work, the digital work comprising at least one of audio content or video content;
determining, by the processor, whether the digital work is a registered digital work based on comparing a first feature of the digital work to first features of a plurality of registered digital works using a first assessment criterion of a hierarchy of assessment criteria, the hierarchy of assessment criteria comprising at least two of a file name, a file size, a source address, a metadata identifier, or a watermark;
responsive to a determination using the first assessment criterion that the digital work is not a registered digital work, applying one or more next assessment criteria of the hierarchy of assessment criteria to determine whether the digital work is a registered digital work until one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work or all of the hierarchy of assessment criteria have been applied, wherein applying a next assessment criterion comprises comparing a second feature of the digital work to second features of the plurality of registered digital works using the next assessment criterion; and
responsive to a determination that one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work, altering, by the processor, a functional behavior of a network device with respect to the transmission.

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.

9. A non-transitory computer readable storage medium having instructions that, when executed by a processor, cause the processor to perform operations comprising:
-
identifying, by the processor, a transmission associated with a digital work, the digital work comprising at least one of audio content or video content; determining, by the processor, whether the digital work is a registered digital work based on comparing a first feature of the digital work to first features of a plurality of registered digital works using a first assessment criterion of a hierarchy of assessment criteria, the hierarchy of assessment criteria comprising at least two of a file name, a file size, a source address, a metadata identifier, or a watermark; responsive to a determination using the first assessment criterion that the digital work is not a registered digital work, applying one or more next assessment criteria of the hierarchy of assessment criteria to determine whether the digital work is a registered digital work until one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work or all of the hierarchy of assessment criteria have been applied, wherein applying a next assessment criterion comprises comparing a second feature of the digital work to second features of the plurality of registered digital works using the next assessment criterion; and responsive to a determination that one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work, altering, by the processor, a functional behavior of a network device with respect to the transmission. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer system comprising:
-
a memory; and a processor, coupled to the memory, to; identify a transmission associated with a digital work, the digital work comprising at least one of audio content or video content; determine whether the digital work is a registered digital work based on comparing a first feature of the digital work to first features of a plurality of registered digital works using a first assessment criterion of a hierarchy of assessment criteria, the hierarchy of assessment criteria comprising at least two of a file name, a file size, a source address, a metadata identifier, or a watermark; responsive to a determination using the first assessment criterion that the digital work is not a registered digital work, apply one or more next assessment criteria of the hierarchy of assessment criteria to determine whether the digital work is a registered digital work until one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work or all of the hierarchy of assessment criteria have been applied, wherein applying a next assessment criterion comprises comparing a second feature of the digital work to second features of the plurality of registered digital works using the next assessment criterion; and responsive to a determination that one of the hierarchy of assessment criteria results in the digital work being identified as a registered digital work, alter a functional behavior of a network device with respect to the transmission. - View Dependent Claims (18, 19, 20)
