The similarity of iris between twins and its effect on iris recognition using box counting

Abstract

One of sciences that growing rapidly is Biometric. In this world, there can't be two identical humans, even though they are twins. Every human being must have different characteristics from the others. The iris is the part of the eye that is protected by the cornea so that it has a relatively stable shape and pattern. Iris recognition is a biometric identification method based on iris patterns. Meanwhile, twins mostly have the same physical characteristics, so it is interesting to investigate how the iris between twins is related and its effect on Iris recognition. In this paper, the relationship or the similarity of iris between twins was studied using a correlation test. Meanwhile, the effect of similarity between twins on iris recognition was investigated from changes in the accuracy of iris recognition when the number of twins’ iris was increased in the data. The database was taken from CASIA Interval and Casia Twin. From this research, the results showed that Iris between twins had a high level of similarity and relationship, it can be seen from the high and significant correlation value, and the number of twins’ iris in the data was negatively related to the accuracy of iris recognition, namely the more iris’s twins on the data, the smaller the accuracy.
