fingerprintingAct of taking an impression of a person's fingerprint. Because each person's fingerprints are unique, fingerprinting is used as a method of identification, especially in police investigations. The standard method of fingerprint classification was developed by Sir Francis Galton and Sir Edward Henry; their system was officially introduced at Scotland Yard in 1901. The U.S. Federal Bureau of Investigation maintains a fingerprint file on more than 250 million people; fingerprints retrieved from a crime scene may be compared with those on file to identify suspects. DNA analysis, which examines regions of DNA unique to each person, is sometimes called DNA fingerprinting. Want to thank TFD for its existence?
