Estimating the Age of an Individual by Analyzing the Lip Print through Suzuki and Tsuchihashi's Classification

Abstract

A forensic examination method called cheiloscopy uses the ridges and grooves on lips to distinguish between forensic instances and those that are not. The goal of the study is to identify the common lip print pattern and its variations across different age groups using Suzuki and Tsuchihashi's kinds classification. Totally 180 participants were split into three age groups (Groups 1: 21–30, Group 2: 31–40, and Group 3: 41–50). The study area is located in a small part of Puducherry. Subsequently, the lip prints were photographed and stored for digital analysis. To enhance visualization, the lip print photographs were uploaded onto Adobe Photoshop 2019, and filters were applied to identify the patterns. Concluding this study, the identification of age groups among individuals might be facilitated through the recognition of these six patterns. This capability will aid in categorizing people in the event of a disaster or explosive case. Since every person has a unique lip print, it is elementary to identify, document, and analyze these patterns when using digital picture analysis.
