各大银行代表在参加伦敦网络安全会议时被告知,许多老年人的指纹消褪严重,以至于机器无法识别。
John Daugman, professor of computer vision and pattern recognition at the University of Cambridge, says: 'Skin dries with age, especially for older women.
剑桥大学计算机视觉和模式识别专业教授约翰•道格曼称:“随着年龄的增长,皮肤会越来越干燥,特别是对老年女性而言。”
'This shrinks the ridge pattern (already quite fine for women, with a spacing of around 0.3 mm), and wrinkles also develop which disrupt the fingerprint pattern.
“手指的指纹脊线会因此变浅(女性的纹线本身就相当浅,约为0.3毫米),而不断生出的皱纹也会破坏指纹纹理。”
'Fingerprints can 'rub off' for bricklayers, stonemasons and other manual laborers — their skin becomes almost shiny.
“瓦匠、石匠以及其他体力劳动者可能将指纹‘擦掉’,他们的皮肤几乎磨得发亮。”
'Gardeners often acquire a lot of scratches on their fingers, and people who work with chemicals, such as cleaners, also suffer erosion of fingerprints.'
“园丁的手指上经常会留下许多划痕,而保洁工人等在工作中接触清洁剂等化学制品的人群,指纹会被化学制品侵蚀。”
Medical professionals have also discovered that some treatments, such as chemotherapy, can cause fingerprints to disappear - sometimes permanently.
