|The sorting of fingerprints into file groups. Classified by general shape, position and size.
|A fingerprint pattern in which the ridge pattern flows inward and returns to the direction of the origin.
|Those not readily seen but that can be developed through powders or chemicals.
|The intentional recording of the friction ridge skin using black printer's ink.
|Print impressions caused by perspiration on the ridges of the fingers being transferred to a surface or occurring as residues of oil, dirt or grease.
|Impressions left in soft substances such as putty, grease, tar, butter or soft soap.
|An arch goes from one side of the finger to another.
|A loop starts and ends at the same side, which is the side of the opening.
|A whorl is roughly circular, with the ridge lines going all the way around.
|Graphic record of an individual's voice characteristics made by a sound spectrograph that recors energy patterns emitted by speech.
|Science Basis of Fingerprint Identification
|The ridge arrangement on every finger of every person is different.
|a computer system that automatically searches a latent fingerprint recovered from a scene.
|a difference in which, in the opinion of the examiner, can be explained.
|a difference between two patterns that can not be explained.
|the study of the of fingerprints.
|center of the finger pattern impression.
|the matching of a latent print to one person as its source to the exclusion of all other people in the world.
|Class One/ Level One Detail
|the general ridge flow of a fingerprint.
|Class Two/ Level Two
|a particular ridge path, including bifurcations, endings, divisions; also referred to as minutiae or Galton's details.
|Class Three/ Level Three
|finer detail concerning individual ridges, such as the shape of the edges, their width, and the pores.
|Stands for Analysis, Comparison, Evaluation, Verification. ACE-V describes the process for comparison of a latent print to a known print.
