Fingerprints and other Biometrics

Biometrics are the measurable biological (anatomical and physiological) or behavioral characteristics used for identification of an individual. Fingerprints are a common biometric modality, but others include things like DNA, irises, voice patterns, palmprints, and facial patterns.
Over the years, biometrics has been incredibly useful to the FBI and its partners in the law enforcement and intelligence communities—not only to authenticate an individual’s identity (you are who are say you are), but more importantly, to figure out who someone is (by a fingerprint left on a murder weapon or a bomb, for example), typically by scanning a database of records for a match.
The FBI has long been a leader in biometrics. We’ve used various forms of biometric identification since our earliest days, including assuming responsibility for managing the national fingerprint collection in 1924. More recently, the Bureau’s Science and Technology Branch created the Biometric Center of Excellence (BCOE) to strengthen our ability to combat crime and terrorism with state-of-the-art biometrics technology. In addition to the BCOE, our Criminal Justice Services Division—with its vast repositories of fingerprints and biographical data—is the FBI’s natural focus for identity management activities. However, important additional biometrics-related work is being undertaken by the FBI Laboratory, such as DNA activities, while voice and face recognition initiatives are being pursued in our Operational Technology Division.

All About Fingerprints
Fingerprints vary from person to person (even identical twins have different prints) and don’t change over time. As a result, they are an effective way of identifying fugitives and helping to prove both guilt and innocence. Learn more:
Biometric Initiatives
We continue to look to new scientific advances to increase the range and quality of our biometric identification capabilities. For more information:
Through the Global Collections Program, we foster national and international relationships related to biometrics in support of counterterrorism and other law enforcement efforts. Our three initiatives include:

Why States Still Use Barrel Bombs

Smoke ascends after a Syrian military helicopter allegedly dropped a barrel bomb over the city of Daraya on Jan. 31.(FADI DIRANI/AFP/Getty Images) Summary Barrel bombs are not especially effective weapons. They are often poorly constructed; they fail to detonate more often than other devices constructed for a similar purpose; and their lack of precision means they can have a disproportionate effect on civilian populations. However, combatants continue to use barrel bombs in conflicts, including in recent and ongoing conflicts in Africa and the Middle East, and they are ideally suited to the requirements of resource-poor states. Analysis Barrel bombs are improvised devices that contain explosive filling and shrapnel packed into a container, often in a cylindrical shape such as a barrel. The devices continue to be dropped on towns all over Syria . Indeed, there have been several documented cases of their use in Iraq over the past months, and residents of the city of Mosul, which was re

Russia Looks East for New Oil Markets

Click to Enlarge In the final years of the Soviet Union, Soviet leader Mikhail Gorbachev began orienting his foreign policy toward Asia in response to a rising Japan. Putin has also piloted a much-touted pivot to Asia, coinciding with renewed U.S. interest in the area. A good expression of intent was Russia's hosting of the Asia-Pacific Economic Cooperation summit in 2012 in Vladivostok, near Russia's borders with China and North Korea. Although its efforts in Asia have been limited by more direct interests in Russia's periphery and in Europe, Moscow recently has been able to look more to the east. Part of this renewed interest involves finding new export markets for Russian hydrocarbons. Russia's economy relies on energy exports, particularly crude oil and natural gas exported via pipeline to the West. However, Western Europe is diversifying its energy sources as new supplies come online out of a desire to reduce its dependence on Russian energy supplies . This has

LONDON POLICE INDIRECTLY ENCOURAGE CRIMINALS TO ATTACK RUSSIAN DIPLOMATIC PROPERTY

ILLUSTRATIVE IMAGE A few days ago an unknown perpetrator trespassed on the territory of the Russian Trade Delegation in London, causing damage to the property and the vehicles belonging to the trade delegation , Russian Foreign Ministry Spokeswoman Maria Zakharova said during the September 12 press briefing. The diplomat revealed the response by the London police was discouraging. Police told that the case does not have any prospects and is likely to be closed. This was made despite the fact that the British law enforcement was provided with video surveillance tapes and detailed information shedding light on the incident. By this byehavior, British law inforcements indirectly encourage criminals to continue attacks on Russian diplomatic property in the UK. Zakharova’s statement on “Trespassing on the Russian Trade Mission premises in London” ( source ): During our briefings, we have repeatedly discussed compliance with the Vienna Convention on Diplomatic Relations, specif
