The purpose of this paper is to prove the "ineq叫ity character of the person's fingerprint". The study was done by using 41 stt1dents'left hand each fingers and contrasting a number of characteristics between them, In order to prove the correlation between them, we used the certain coef­ficient. For this 205 (41 persons X 5) fingerprints study, the c01Telation coefficient was formally set be­tween - 1 and + 1. It explain the strong possibility of inequality characteristics when the data is close to zero. The following three results were obtained. (1) The average data, which was obtained between M, (ridege ending) and Mb (bifurcation) in each finger, was -0.01. (2) The average data, which was obtained for a certain quadrant in each finger, was 0.15. (3) The average data, which was obtatined for all quadrants in each finger, was 0.01. Based on the observations we had above, we found no matched ch紅acteristics between them and agreed with the idea of the "inequality ch紅acter of the person's fingerprint".
