Abstract

Several previous studies have investigated the gender difference of the fingerprint features. However, regarding to the statistical significance of such differences, inconsistent results have been obtained. To resolve this problem and to develop a method for gender determination, this work proposes and tests three fingertip features for gender determination. Fingerprints were obtained from 115 normal healthy adults and comprised of 57 male and 58 female volunteers. All persons were born in Taiwan and were of Han nationality. The age range was18-35 years. The features of this study are ridge count, ridge density, and finger size, all three of which can easily be determined by counting and calculation. Experimental results show that the tested ridge density features alone are not very effective for gender determination. However, the proposed ridge count and finger size features of left little fingers are useful, achieving a classification accuracy of 75% (P-value<0.001) and 79% (P- value<0.001), respectively. The best classification result of 86% accuracy is obtained by using ridge count and finger size features together. This paper closes with a discussion of possible future research directions.

利用指尖特征确定性别

已有研究对指纹特征的性别差异进行了研究。然而，关于这种差异的统计意义，得到了不一致的结果。为了解决这一问题并建立一种性别鉴定方法，本文提出并测试了三种用于性别鉴定的指尖特征。指纹采集自115名正常健康成人，包括57名男性和58名女性志愿者。所有人都是在台湾出生的汉族。年龄范围为18-35岁。本研究的特征是脊数、脊密度和手指大小，这三者都可以很容易地通过计数和计算来确定。实验结果表明，仅用测试的脊密度特征来确定性别并不是很有效。然而，所提出的脊数和左手小指的手指大小特征是有用的，分别实现了75% (P值<0.001)和79% (P值<0.001)的分类准确率。将脊数和手指大小特征结合使用，分类准确率达到86%。本文最后对未来可能的研究方向进行了讨论。
