Fingerprinting: Live Scan Enhances Benefits

Fingerprinting has been the simplest, most accurate, and most cost-effective way to affirm the identity of an individual for more than a century. Other methods were employed before fingerprinting, but they ultimately proved to be unacceptable. For example, in the 19th century, the Bertillon System relied on a mathematical formula based on the measurements of specific bones in a human body, which were thought to be unique to each person. In 1903, however, two prisoners in Leavenworth, Kansas, had the same name and similar bone measurements. They were consequently identified as being a single person. The confusion was cleared up when authorities used fingerprinting to determine that the men were indeed two separate individuals, and the Bertillon System was discredited.

There is evidence that fingerprints were used for identification even by the ancient Egyptians, but despite its long history, critics continue to question the reliability of fingerprinting. Criticisms usually focus on the possibility of human error to enter the fingerprinting process. And it is true that, in the past, the actual process of using ink and the need for administrators to “roll” the prints created an error-prone environment. The actual physical “rolling” impacted the usefulness of prints, making them illegible if too much or too little ink was used or if the administrator did not have the proper technique in rolling the finger from side to side as required. Other factors, like the amount of perspiration on an individual’s fingers, could influence the quality of the printing.

Enter the Live Scan system. Live Scan reduces the potential for human error and maximizes the quality of fingerprints, supporting the use of fingerprinting as the most inexpensive, reliable, and recognized identification system available. Fingerprints have remained the chief source of identity vertification and recognition over the years because every person’s fingerprints are unique. They can’t be changed like hair color, and they can’t be guessed at or forgotten as can methods that don’t rely on biometric elements. An individual must be physically present in order to be fingerprinted, so the process clearly identifies who he or she is.

Congress gave the U.S. Federal Bureau of Investigation (FBI) the authority to create anĀ  dentification Division in 1924, which resulted in a centralized repository of all fingerprints taken. This made it easier to identif repeat offenders. Today, this early effort has evolved into the computerized AFIS system, which has become well-known among the general public due to popular television programs like CSI. The U.S. Department of Justice has relied on computerized Live Scan fingerprinting methods, performed by certified technicians and using quality-rated equipment since 2005. The sophistication of modern Live Scan technology continues to evolve and improve, putting to rest the criticisms aimed at fingerprinting as an identification medium and ensuring the method will continue as the ultimate source of identity verification for some time
