An automated system used to assist in the analysis of bullets and cartridge cases. IBIS was developed by the Bureau of Alcohol, Tobacco, firearms, and Explosives (ATF) along with Forensic Technology, a Canadian company. IBIS equipment is supplied to participating laboratories through ATFâ€™s National Integrated Ballistic Information Network (NIBIN) program. Much like automated fingerprint database software, IBIS is designed as a screening tool but does not replace the firearms examiner for making final identifications. IBIS has two computational components, one for data acquisition and one for analysis, and an analysis produces a list of candidate matches from the central databases. IBIS has been particularly valuable in linking seemingly unrelated crimes by showing that the same weapon was used in both or all instances.
