Dermatoglyphics can be found in the thick skin of both hands and feet which make the identification process possible, however morphological changes throughout life can affect identification in elderly individuals. Considering that dermatoglyphics is an important biometric method, due to it being practical and inexpensive, this longitudinal and retrospective study was aimed to evaluate the morphological variations in fingerprints obtained from men and women (n=20) during their adult and elderly stages of life; the time between obtaining the two fingerprints was 33.5±9.4 years. For the morphometric analysis, an area of 1 cm(2) was selected to quantify the visible friction ridges, minutiae, interpapillary and white lines, and later side-by-side confrontation was used to determine the identity of the individuals. Our results showed a reduction of friction ridges, an increase in the number of white lines for the group (men and women) and a decrease in the number of interpapillary lines in the group of women. It also showed that the selection of compatible fingerprints by the automated AFIS/VRP system allowed the identification of 23 individuals (57.5%), but when the identification was made by the automated AFIS/VRP system, followed by the analysis of archived patterns to eliminate incompatible fingerprints, determination of the identity of 28 individuals (70.0%) was possible. The dermatoglyphics of the elderly suffered morphometric changes that prevented the identification of 30% of them, probably due to the aging process, and pointed to the importance of improving the methods of obtaining fingerprints to clarify issues related to the identification of the elderly.
皮纹学存在于双手和双脚的厚皮肤中，这使得身份识别过程成为可能，然而，一生中的形态变化会影响老年人的身份识别。鉴于皮纹学是一种重要的生物识别方法，因其实用且成本低廉，本纵向回顾性研究旨在评估从成年期到老年期的男性和女性（n = 20）指纹的形态变化；两次获取指纹的时间间隔为33.5±9.4年。对于形态计量分析，选择1平方厘米的区域来量化可见的摩擦嵴、细节特征、乳头间线和白线，随后采用并排对比来确定个体身份。我们的结果显示，摩擦嵴减少，该组（男性和女性）白线数量增加，女性组乳头间线数量减少。结果还表明，通过自动指纹识别系统/虚拟纹线模式系统选择兼容指纹可识别23人（57.5%），但当通过自动指纹识别系统/虚拟纹线模式系统进行识别，随后分析存档模式以消除不兼容指纹时，有可能确定28人（70.0%）的身份。老年人的皮纹学发生了形态计量变化，导致30%的老年人无法被识别，这可能是由于衰老过程所致，这也表明改进指纹获取方法对于厘清与老年人身份识别相关问题的重要性。
