Integrated Automated Fingerprint Identification System

Last updated

The Integrated Automated Fingerprint Identification System (IAFIS) is a computerized system maintained by the Federal Bureau of Investigation (FBI) since 1999. It is a national automated fingerprint identification and criminal history system. IAFIS provides automated fingerprint search capabilities, latent searching capability, electronic image storage, and electronic exchange of fingerprints and responses. IAFIS houses the fingerprints and criminal histories of 70 million subjects in the criminal master file, 31 million civil prints and fingerprints from 73,000 known and suspected terrorists processed by the U.S. or by international law enforcement agencies.

Employment background checks cause citizens to be permanently recorded in the system.[ dubious – discuss ] For instance, the State of Washington mandates that all applicants seeking employment in an inpatient setting that houses vulnerable minors (such as children who are mentally challenged, physically or emotionally ill) are fingerprinted and entered into IAFIS as part of their background check in order to determine if the applicant has any record of criminal behavior. [2]

Fingerprints are voluntarily submitted to the FBI by local, state, and federal law enforcement agencies. These agencies acquire the fingerprints through criminal arrests or from non-criminal sources, such as employment background checks and the US-VISIT program. The FBI then catalogs the fingerprints along with any criminal history linked with the subject.

Law enforcement agencies can then request a search in IAFIS to identify crime scene (latent) fingerprints obtained during criminal investigations. Civil searches are also performed, but the FBI charges a fee and the response time is slower.

A more advanced Next Generation Identification system became operational in 2011. [3] [4]

Technology

The device used for scanning live fingerprints into AFIS is called Live scan. The process of obtaining the prints by way of LiveScan employs rolling prints or placing flat impressions onto a glass platen above a camera unit. The process of obtaining prints by placing a ten-print card (prints taken using ink) onto a flatbed or high-speed scanner is called CardScan (or occasionally DeadScan). In addition to these devices, there are other devices to capture prints from crime scenes, as well as devices (both wired and wireless) to capture one or two live finger impressions. The most common method of acquiring fingerprint images remains the inexpensive ink pad and paper form. Scanning forms ("fingerprint cards") with a forensic AFIS complies with standards established by the FBI and National Institute of Standards and Technology (NIST).

To match a print, a fingerprint technician scans in the print in question, and computer algorithms are utilized to mark all minutia points, cores, and deltas detected on the print. In some systems, the technician is allowed to perform a review of the points that the software has detected, and submits the feature set to a one-to-many (1:N) search. The better commercial systems provide fully automated processing and searching ("lights-out") of print features. The fingerprint image processor will generally assign a "quality measure" that indicates if the print is acceptable for searching.

Speed

The average response time for an electronic criminal fingerprint submission is about 27 minutes, while electronic civil submissions are processed within an hour and 12 minutes. IAFIS processed more than 61 million ten-print submissions during fiscal year 2010. [1]

A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers.

A background check is a process a person or company uses to verify that an individual is who they claim to be, and this provides an opportunity to check and confirm the validity of someone's criminal record, education, employment history, and other activities from their past. The frequency, purpose, and legitimacy of background checks vary among countries, industries, and individuals. An employment background check typically takes place when someone applies for a job, but it can also happen at any time the employer deems necessary. A variety of methods are used to complete these checks including comprehensive database search and personal references.

CrimTrac was a former Agency in the Attorney-General's Department that was merged with the Australian Crime Commission on 1 July 2016 to form the Australian Criminal Intelligence Commission.

Automated fingerprint identification is the process of using a computer to match fingerprints against a database of known and unknown prints in the fingerprint identification system. Automated fingerprint identification systems (AFIS) are primarily used by law enforcement agencies for criminal identification purposes, the most important of which is the identification of a person suspected of committing a crime or linking a suspect to other unsolved crimes.

The Henry Classification System is a long-standing method by which fingerprints are sorted by physiological characteristics for one-to-many searching. Developed by Hem Chandra Bose, Qazi Azizul Haque and Sir Edward Henry in the late 19th century for criminal investigations in British India, it was the basis of modern-day AFIS classification methods up until the 1990s. In recent years, the Henry Classification System has generally been replaced by ridge flow classification approaches.

The FBI Name Check is a background check procedure performed by the Federal Bureau of Investigation for federal agencies, components within the legislative, judicial, and executive branches of the federal government; foreign police and intelligence agencies; and state and local law enforcement agencies within the criminal justice system. The FBI Name Check is performed by the FBI as a part of the National Name Check Program, which dates back to Executive Order 10450 that was issued during the Eisenhower Administration. The FBI Name Check for an individual involves a search of the FBI's Central Records System Universal Index for any appearance of the name of the individual, as well as close phonetic variants and permutations of that name, in any of the records stored in the Universal Index. If any such occurrences are found, the Name Check also involves retrieval and analysis of the relevant paper and electronic files from local FBI offices and from other law-enforcement agencies.

Next Generation Identification (NGI) is a project of the Federal Bureau of Investigation (FBI).

The NGI system will be a more modular system. It will also have more advanced lookup capabilities, incorporating palm print, iris, and facial identification. The FBI first used this system in February 2011.
