A Biometric Approach for Personal Identification Using 2-D Lip Images of Brahmin & Baniya Communities

Abstract

Personal identification is an important fact in Forensic investigation. Identification through biometric systems is motivated by real life criminal and Forensic applications. Present study was to determine any differences in lip patterns and lip measurements between two communities and to ascertain whether this behold the potential for determination of sex of an individual. A total of 80 subjects of both Brahmin and Baniya community of Bundelkhand region of 20–40 years were taken. Lip measurements were taken along with the lip images and classified according to Tsuchihashi's classification. Statistical analysis indicated that there were significant differences between sexes of both communities. There is correlation of photographic length and width ratio to actual dimension of lips in both the sexes. The overall accuracy for sex determination in Brahmin community is found to be 47.1875%, whereas in Baniya community it was 38.125%. Hence, the percentage of determining the differences in lip images of males and females in both communities was 42.65%. This study can provide a preliminary idea about the use of lip images and measurements along with lip pattern as a biometric system in sex determination among both communities.
