The Breen Intelligence Directorate (BID) was an intelligence gathering body within the Breen Confederacy that was a civilian governmental program and a sub-division of the Confederate Information Bureau. It possessed a number intelligence analysts that were charged with sifting through gathered information in order to spot null values; namely anomalies that identified suspicious individuals that were working against the Breen government.
To accomplish this, they made use of artificial intelligences in various Breen settlements to check identichop codes in order to determine a citizen's purchasing history as well as economic profile. The data was used to deliver targeted advertising tailored for maximum enticement with similar modules being present into a city's public information kiosk. This created an elaborate surveillance grid for intelligence analysts to sift through the network in order to track the moivements and habits of civilians as well as construct virtual models to uncover suspicious behavior. The information was not only a useful intelligence gathering tool but aided in enhancing commercial profits. The data gathered was often presented to analysts by way of a holomatrix.
In 2382, Chot Nar uncovered two null values at Salavat due to their suspicious behavior that was picked up by the Directorate's surveillance systems. These were actually spies from the Federation who had arrived at the planet in order to eliminate a Breen underground shipyard that was reverse engineering slipstream technology for the Typhon Pact.
