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 method for altering the behavior of a device based on the transmissions of digital works comprising:

maintaining a registry of information permitting identification of digital 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 to assess whether the at least one digital signal includes a transmission of a registered digital work;

accumulating statistical measurements of the features of the transmitted digital works; and

altering the functional behavior of the device based on the comparison of the transmitted work.

2. The method of claim 1, wherein the device is a network component.

3. The method of claim 1, wherein the functional behavior that is altered is allocating bandwidth to different categories of network use.

4. The method of claim 1, wherein a database of frequently identified digital works is maintained such that these works could be inserted into the digital stream in place of the original source transmission.
