Classification and Identification of Individuals Using Analysis Lip Prints

Abstract

Identifying individuals is a major challenge for forensic investigators, as DNA and fingerprints are highly valuable, but are not always readily available at crime scenes. Lip prints could be used in this context since they are unique to each individual. Lip-print study (Cheiloscopy) is a reliable biometric technology and is considered a unique parameter for identification. This study was determined lip print patterns among samples of the Salah El-Din population in Iraq and distribution their pattern type of lip print by using a program in MATLAB. In this study, it was established that there are significant differences between populations, countries, and genders when it comes to the distribution of lip prints. Materials and Methods: A total of participants was 100 (50 females & 50 males) their ages more than 10 years old. The lip print was divided into six quadrants on white copy paper then examined with technology using the program in MATLAB to determine the classification of lip print types for pattern distribution. Lip print was recorded by the usage of red natural color and healthy, white copy papers, and tissue paper, the obtained prints were first examined and later analyzed and interpreted.Results: This study discovered that no two samples from the same family have identical lip-print patterns. Females had the greatest recorded pattern of groove type I (long vertical grooves), whereas males had the highest recorded pattern of groove type II (branched grooves). This pattern was most observed in the lower middle region. The present study proved that lip prints of males and females are different types in different countries.Conclusion: lip prints are unique for every individual even in between the family. Hence, Lip prints play a vital role as a supplementary tool in the personal identification of suspects or unknown identity.
