Imagine you’re standing in line to buy a 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(二维码) with your smart phone, 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 (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.
In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, 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 imagine. " Biometrics is ideally good 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 iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, 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 last 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 smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."
1.Which is the latest identification technology in a smart phone according to the passage?
A. Face scanning. B. Eye scanning.
C. QR Code scanning. D. Fingerprint scanning.
2.What is a major problem of the iPhone X's face ID system?
A. It takes too long to unlock the phone.
B. It often fails to recognize its owner's face.
C. Face data can be used for other purposes.
D. Different faces can be used to unlock the same phone.
3.What is Anil Jain's opinion about biometric security?
A. It is as secure as traditional measures.
B. It is perfect without much improvement.
C. It has caused much trouble for the police.
D. It should be used with other security measures.
4.What does the author intend to tell us in this passage?
A. The popularity of biometrics.
B. Security problems of biometrics.
C. Various problems with biometrics.
D. Great changes caused by biometrics.
