Why fingerprints can never replace bank passwords?
    2017-October-26  08:53    Shenzhen Daily

Millions of older people, manual laborers and cancer sufferers could be unable to use their fingerprints to log in to online bank accounts, Money Mail revealed.

British banks are investing millions of pounds in fingerprint technology to replace passwords and PINs.

Most already allow customers to log in to their mobile banking app by holding a finger against a sensor on their smart phone.

Others are trialing new credit card and cash machines where, instead of entering a PIN, people use their fingerprint to pay or withdraw money.

But banks may have to rethink after warnings the technology could be fatally flawed.

Delegates representing major banks at a London cyber security conference were told many older people’s fingerprints are too faded for the machines to recognize.

John Daugman, professor of computer vision and pattern recognition at the University of Cambridge, says, “Skin dries with age, especially for older women.

“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.

“Fingerprints can ‘rub off’ for bricklayers, stonemasons and other manual laborers — their skin becomes almost shiny. Gardeners often acquire a lot of scratches on their fingers, and people who work with chemicals, such as cleaners, also suffer erosion of fingerprints.”

Medical professionals have also discovered that some treatments, such as chemotherapy, can cause fingerprints to disappear — sometimes permanently.

Fingerprints are considered more secure than passwords, because they are difficult to replicate and can’t be written down, told to anyone or guessed. They can’t be forged like a signature, either.

But it’s not reliable enough to be rolled out as a primary way of paying for things or logging in to accounts, because there are loads of ways one can lose or damage one’s prints.

Therefore, there must always be a back-up so that if it doesn’t work, there is another way of paying, such as with a PIN or password.

据《每日邮报》财经频道报道,众多老年人、体力劳动者和癌症患者可能无法用他们的指纹登录网上银行账户。

英国银行投入大量资金,用指纹技术取代密码和个人识别码。

如今,大多数用户只要将手指按在智能手机的传感器上,就可以登录他们的手机银行应用软件。

还有一些机构正在试用采用指纹技术的新型信用卡和自动柜员机。用户无需输入密码就可以进行支付或者取款。

但银行可能不得不重新考虑这些计划,因为有人警告,指纹技术可能存在致命缺陷。

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。

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。”

“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。”

“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。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。”

医学专家还发现,化疗等一些医疗方法有时甚至让指纹永久消失。

人们认为指纹比密码更安全,因为指纹难以复制,无法写下来、不能透露给别人,也无从猜测。和签名不同,指纹不能伪造。

但是指纹识别技术的可靠性还不足以使其成为一种首要的支付或账号登录方式。因为很多因素都能让你失去或破坏自己的指纹。

所以必须留一个备用方式,如果无法进行指纹识别,那么还可以用另外一种方式付款,比如个人识别码或密码。
