Abstract: “The learning and analysis of palatal patterns for verifying the identity of an individual is termed as palatoscopy or palatal rugoscopy. Since, dizygotic twins (fraternal twins) are generated from two different eggs at the time of fertilization. Therefore, the fraternal twins differ from each other in their face structure and gait signature etc. But, the identical twins are generated from the same egg. Hence they share the same DNA sequence and same face structure. It is almost impossible to identify identical twins (monozygotic twins) on the basis of their face structure or DNA sequence or gait signature. But, it is observed that they can be differentiated / identified on the basis of their palatal rugae patterns. This research paper presents a novel mathematical model for identifying identical twins on the basis of their palatal patterns structures. The palatal curves of identical twins are represented by unique symbols and curve tracing based approach is used for comparing the palat”
