Technological advances in criminal identification procedures Essay

Technological advances in unlawful identification procedures - Essay subject deoxyribonucleic acid depth psychology is more specific, as each set of nucleic acid in each person is unique. In addition, as DNA from one persons soundbox cell is identical in each cell in the body of that person, a cell sample fundament be obtained from any part of that persons body. Thus, persons can be identified by referring to a DNA database which compares and matches a persons genetic information other persons DNA profile found in that database (Gans and Urbas, 2002).DNA analysis still provides limited amounts of information about a persons characteristics though it is believed that in the near future, researches may come up with a better method of DNA analysis (National Institute of Justice 2000, pp. 18-19 van Oorschot et al. 2001). At present, the use of DNA analysis in the judicial system involves comparison of DNA from two origins, for poser comparing DNA that came from the location of the c rime and that from a criminal (Gans and Urbas, 2002).Biometrics is the identification method that identifies persons based on their behavior and psychological profile. Often, this method is preferred than others because a person must be present at the identification point at the instance of verification and it eliminates the need for the memorization of passwords and PIN numbers. Biometric profiles increases the take of security by restricting access to that particular person only and can be potentially used in the protection of certain valuables such(prenominal) as ATM cards, cell phones, PCs etc. It has many uses such as for criminology and forensics, but it may have several civilian uses as well in the near future (Ross et al, n.d.). Aside from not having to memorize keywords or PIN, biometric identification is very accurate and secure, can be done comfortably and quickly and no documents or paraphernalia is needed to use it (Biometric identification - advantages, n.d.). Intra -agency databases for DNA Intra-agency databases for DNA are actually a collection of DNA records that can be easily accessed by different law enforcement agencies. This will speed up the identification of criminals and solving cases. Law enforcement and other g all overnment agencies have been left behind by other sectors in having efficient database systems. This is due to their dependency on public funds, which is often insufficient and/or hastily planned. This lack of a proper criminal identification system slows down or hinders the judicial process. Criminals are aware of this lack of identification system and thus put them at and advantage over the authorities (Schroeder et al, n.d.). FingerprintAn Automated Fingerprint appellation System (AFIS) analyses, compares and then matches an individuals set of fingerprints against a fingerprint database. This system has various uses including criminal, civilian, electoral, academic purposes etc (Automated Fingerprint Identification Sy stem, 2006). It is recommended that fingerprint matching be done in two stages namely pattern- type combination search and minutiae matching.
