A Literary Survey on Multimodal Biometric Identification of Monozygotic Twins

Abstract

Biometrics is one of the major techniques which is used to identify a person’s exclusive physical characteristics. Studying the biological traits of a human physique by extracting a feature set from the obtained data, and matching the sets with the database is known as Biometrics. Consistent and accurate verification and identification of a person are extremely significant in various business transactions, Law Enforcement, Surveillance and access to privileged information. Though there is a high progression in the Biometric Modality, identifying Monozygotic Twins seems to be a very challenging task as identical twins are highly analogous to each other and differentiating them is practically impossible. As Monozygotic Twins are composed of a single embryo they cannot be distinguished by considering their DNA results. Hence, the lack of appropriate identification system may lead to many critical scenarios. The increase in twin births has led to an up gradation of the present biometric system that may accurately regulate the uniqueness of a person by comparing their corporal fields. The current biometric method which is used for verification is sufficient to differentiate one person from another. In this paper, we study about distinguishing identical twins or monozygotic twins by different multimodal biometric technologies such as facial marks, facial features, hair-whorls by means of PCA Algorithm.
