The usage of human fingerprints for identification has a long history, tracing back to the Chinese usage of fingerprints 200 BCE (International Association for Identification, et al., 1). The Qin Dynasty had records of handprint identification being used as evidence for investigations about burglary. It is not clear to what degree these methods were effective or accurate but this is the oldest known example of the usage of handprints for identification purposes. From this point, there are some sporadic instances of fingerprint usage. However, fingerprinting began to be seriously evaluated in the 19th century (ibid).
Sir Francis Galton, a 19th Century anthropologist and biologist, began studying fingerprints in the late 1800s (Gega, 1). Galton was a pioneer in fingerprint identification. He established “the individuality and permanence of fingerprints” (International Association for Identification, et al., 1). This is important for two reasons. The individual nature of fingerprints is key for the purposes of identification. Galton estimated that the odds of the same two individual fingerprints occurring was 1 in 64 billion (ibid). This percentage is so low that fingerprints can successfully be relied on as accurate and consistent identification tools. The second part is also equally important. Many biological identification factors, like height, weight, hair color, dental records, or foot size, will change over the course of a human lifetime. These methods had been used by

For over a century fingerprints have been one of the most used tools of forensic science. Fingerprints have been used to identify criminals of small crimes
The next significant advancement in fingerprinting was achieved by an Englishman, Dr. Henry Faulds, who created a fingerprint classification method and suggested using printers’ ink to obtain quality fingerprints (The History of Fingerprints). Perhaps the most important advancement in fingerprinting came in 1892, when a British Anthropologist, Sir Francis Galton, published the book Fingerprints. For a while it had been thought that no two fingerprints were identical. However, Galton became the first to scientifically prove this, as well as the fact that fingerprints remain unchanged throughout a person’s life (The History of Fingerprints). It was these two facts that made fingerprinting the preferred method of identification.

For the past several decades, ninhydrin has been used in the development of fingerprints from surfaces. The fingerprints revealed by ninhydrin have been used to compare against other known fingerprints, whether from the person of interest or a database, which can lead to a match on a victim or a suspect on a case. But what about the fingerprints that do not have a match in a database? Can that print be of any use to forensic scientists? In the journal article, “New Horizons for Ninhydrin: Colorimetric Determination of Gender from Fingerprints” the researchers attempt to determine if a fingerprint can yield more than just a picture that can be used for comparison.
According to Merriam- Webster Dictionary; an impression or mark made on a surface by a person's fingertip, especially as used for identifying individuals from the unique pattern of whorls and lines. One of the most important parts of a forensic investigation is fingerprinting. As fingerprints are unique to each individual, they serve as a highly accurate way for law enforcement agencies to identify a suspect, as well as potentially prove their guilt or innocence. This paper will talk about how a cold case was solved by a fingerprint, the procedures, reasons why the case was not solved at the time of the crime and the results.
“Fingerprint recognition is one of the divorce inference using the impressions made by the minute ridge formations or patterns found on the fingertips. No two people have exactly the same arrangement of the ridge patterns, and the remaining patterns of any one individual unchanged. Fingerprints infallible provide a means of personal identification. Other personal characteristics may change, but not fingerprints”. (1)
Fingerprinting is used for many things, such as a robbery, or at a crime scene. Fingerprints were first discovered in 1870 by Alphonse Bertillon, who was a French anthropologist. In 1892, Juan Vucetich had made the first criminal report using a fingerprint. In 1905 America used fingerprints for identification. When America started using fingerprints for identification they had to match the fingerprints manually when needed. When technology was able to enter fingerprints, and match them with anonymous ones, it helped identification immensely.
Even more in the future, research into the underlying science under the fingerprint would prove the science behind a fingerprint's individuality. These events proved that even though fingerprinting had little research on its development on the fingertips and how it related to individuality, the United States government used fingerprinting widely over time for forensic
Doctor Henry Faulds published a piece on the use of fingerprinting in England 1880 and then two years later Gilbert Thompson use thumbprints to avoid fraud in the United States on check. In Francis Galton had created a classification system for fingerprints working on a past principle from Sir William Herschel. During the years of 1901 and 1920 many countries started to use fingerprints and in America in 1924 in America, the FBI had launched the identification division. In general, it has been coming a long way but eventually science and technology had evolved far enough for fingerprinting to become an important forensic science tool. To the point where now there are databases that contain over millions of fingerprint images that are available for comparison and
Then William Herschel began to use fingerprints in his role as Chief Magistrate in 1958. In 1877, he imposed the fingerprints as authentication authorities. In 1880, he wrote an article “skin furrow of the hand”, where he sanctioned the use of fingerprints as a method of signature and identification. In the same year, the individuality of fingerprints was suggested for the first time scientifically by Henry Fauld.
As the unrelenting demand for smartphones continues to increase, many technology companies are looking for ways of making such devices easier, faster, and more user friendly. Many smartphones are equipped with fingerprint readers, allowing the user to access their phones securely and quickly without having to type in their pin or passcode. This prevents users from having to remember dozens of random passphrases that, in theory, a hacker could potentially guess and be granted access into. However, this poses a serious question - How secure is fingerprint authentication and why should consumers trust that this technology will keep their information safe? Similarly,
According to Jain Anil, fingerprint-based identification is the oldest method which has been successfully used in numerous applications and though Bertillon’s anthropometry raised many valid points in forensic science, it was discarded and replaced by the fingerprint identification method after Bertillon’s death 1914.
Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.
