顛倒；倒轉(zhuǎn)；翻轉(zhuǎn)發(fā)布：2024/11/7 7:0:1組卷：1引用：3難度：0.8687．Imagine you're standing in line to buy an after-school snack at a store.You step up to the counter and the cashier scans your food.Next，you have to pay.But instead of scanning a QR code（二維碼）with your smartphone，you just hold out your hand so the cashier can scan your fingerprint.Or，a camera scans your face，your eyes or even your ear.
Now，this type of technology might not be far away.As technology companies move away from the traditional password，biometric（生物識別的）security，which includes fingerprint，face and voice ID，is becoming increasingly popular.
In 2013，Apple introduced the iPhone 5s，one of the first smartphones with a fingerprint scanner.Since then，using one's fingerprint to unlock a phone and make mobile payments has become commonplace，bringing convenience to our lives.And since last year，Samsung has featured eye-scanning technology in its top smartphones，while Apple's new iPhone X can even scan a user's face.But despite its popularity，experts warn that biometrics might not be as secure as we'd imagined. "Biometrics are ideally good，but in practice，not so much" said John Michener，a biometrics expert.
When introducing the new iPhone's Face ID feature，Phil Schiller，Apple's senior vice president，said，"The chance that a random person in the population could look at your iPhone X and unlock it with their face is about one in a million." But it's already been done.In a video posted on community website Reddi，two brothers showed how they were each able to unlock the same iPhone X using their own face.And they aren't even twins.
"We may expect too much from biometrics，" Anil Jain，a computer science professor at Michigan State University，told CBS News. "No security systems are perfect."
Earlier this year，Jain found a way to trick biometric security.Using a printed copy of a thumbprint，she was able to unlock a dead person's smartphone for police，according to tech website Splinter. "It's good to see biometrics being used more，" Jain told CBS News，"because it adds another factors for security.But using multiple security measures is the best defense."
