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.
