in China T’ang dynasty, fingerprints were used for business. Dactyloscopy started in the 19th century by William Herschel. He required indians to add their fingerprints to contracts. In 1877, fingerprints were used to identify prisoners. In Japan, fingerprints were molded in pottery which interested Henry Faulds, a health missionary in Tokyo who published scientific paper in 1880 about fingerprints identifying criminals. Henry Faulds thought that fingerprints were very unique. fingerprints could be used for sorting purposes to help with identification. The ink and transfer method was first used to discover criminals. Identification used to always be an issue for the criminal justice system. Before, prisoners used to often get branded or tattooed, or even limbs cut off to be identified as a criminal. This practice was then abolished in the early 1800’s. Photography used to help but then became too overwhelming for the system. in 1881, Alphonse Bertillon suggested using body measurements to identify offenders. Height, weight, width of head length of foot were examples of the measurements that were to be used. Science of human measurements is called anthropometry. Francis Galton studies dactyloscopy and anthropometry and published 2 books which were used to classify fingerprints using loops, whorls, and arches. He showed that fingerprints stay the same from birth to death, no 2 fingerprints are the same even on identical twins and fingerprints can not be

People in the military are fingerprinted, and it is also required for many other occupations and organizations. When it comes time to match a fingerprint with an individual, it is quite easy due to the wide library of fingerprints the FBI maintains. This library contains the fingerprints of “more than 10%” of the U.S. population. For smaller cases, law enforcement are given access to this library directly from a police station ("Forensic Science" [Gale] 18).

Fingerprint analysis is a method of identifying individuals based on the unique patterns of ridges and valleys on their fingertips. In Dahmer's case, investigators were able to use fingerprints to identify the remains of his victims and link them to specific crime scenes. Fingerprint analysis has been used in forensic investigations for over a century and is considered to be a highly reliable method of identification. It is based on the fact that no two individuals have the same fingerprint patterns and that these patterns remain consistent throughout a person's life. In Dahmer's case, fingerprint analysis was used to identify the remains of several of his victims, including Anthony Sears and Ernest Miller.

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

In the lab report three students are tested along with one suspect. Student number two’s DNA matched the suspects DNA. The student’s DNA’s are cut with five different enzymes as well as the suspects DNA. Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.

In 1888, Sir Francis Galton noticed that fingerprints never changed due to cuts, burns, or age and he scientifically proved that fingerprints could be used to identify individuals and could even be used to convict a criminal of a crime. 3 years later, Juan Vucetich, an Argentine police officer, proved a woman murdered her two sons by using a bloody handprint on the door post of their home. This was the first criminal case ever to be solved by a fingerprint identification and the use of fingerprinting as crime scene evidence

To begin, biometrics are considered unique physical characteristics, such as DNA, palm prints, fingerprints and even facial recognition, that can be used in an automated form to recognize a person. In sum, biometrics are biological measurements (“Next Generation Identification”). In the criminal justice field, biometrics are used often to identify suspects. Examples of this type of technology include Advanced Fingerprint Identification Technology (AFIT), and the Integrated Automated Fingerprint Identification System (IAFIS). Biometrics are important in today’s world and with the rapid advancement of technology, we can expect the use of them to increase in the upcoming years.
