Notes: Henry-FBI Classification System Edward Henry developed a method of classifying fingerprints that was later modified by the FBI. This system divides all sets of fingerprints into 1024 groups. This is done so that, when an unknown set of fingerprints is submitted for comparison and identification (such as those of a Jane Doe), most of the millions of sets of prints on file can be weeded out. Then, only a small amount of sets will actually have to be compared in order to find a match and identify that individual. Today, computers perform this first major elimination, but after this, manual comparison must still be performed by an expert. 1.
