CarnivorePE is inspired by DCS1000, a piece of software used by the FBI to perform electronic wiretaps. (Until recently, DCS1000 was known by its nickname "Carnivore.") Improving on the FBI software, CarnivorePE features new functionality including: artist-made diagnosic clients, remote access, full subject targetting, full data targetting, volume buffering, transport protocol filtering, and an open source software license. Carnivore is created by RSG.
