Abstract: Tracking digital asset infringement activities and infringers on peer-to-peer networks. One method for assessing notice effectiveness of unauthorized distributors of content on a peer-to-peer network comprises processing peer data from a plurality of peers on the network, wherein the peer data aids in identification of individual unauthorized distributors. The embodiment includes creating a trial with a trial base population of the unauthorized distributors and a trial capture window, determining metrics for measuring the notice effectiveness, selecting a randomization methodology for the trial, performing the trial with the trial base population over the trial capture window according to the randomization methodology and issuing notices to some of the unauthorized distributors.

Abstract: A monitoring station is used to monitor a computer network for illegal or undesirable content. The monitoring station conducts searches based on a set of criteria and optionally downloads and examines suspected files. Once the monitoring station identifies illegal or undesirable content, it sends an electronic notice to a control station. The control station derives a enforcement order from the electronic notice based on enforcement rules. The control station sends the enforcement order to a traffic controller. The traffic controller executes the enforcement rule by limiting the access of a network node. In a further embodiment multiple monitoring stations, control stations and traffic controllers may be used.
