Application of Metric System for Individualization from Lip Prints

Abstract

In forensic science, the main framework of an investigator is to deal with the distinct types of evidences and to reveal the identity of an individual/suspect. These evidences may be in form of physical, biological or chemical forms. The evidences are recovered in various forms such as patent, latent, plastics or in semi-visible forms. A few of the evidences which are observed in physical forms but also carry the biological substantial in form of DNA along with it. It includes the latent fingerprints, palm prints, lip prints, ear prints etc. Similar like the palmar surface, the lip prints are also considered perpetual, unique to an individual. The furrows or wrinkles make if different from other individuals for identification. This study was conducted to conclude the identity of suspect/accused by using the metric system. To conclude the identity, six parameters were fixed along an intensified lip print over documents. As a resultant of this study, four parameters concluded the identification of suspect at p<0.10 confidence level. While two parameters present the symptoms of variation in the implementation of lip print over the surface. The result of this study can use to nab the suspect and put them in the judicial system.
