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 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.
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 lasts year, San-sun has featured eye-scanning technology in its top smartphone, while Apple's new iPhone X can even scan a user's face.
When introducing the new iPhone's Face ID feature at Apple's Keynote Event in September. Phil Schiller, Apple's senior vice president, said. “
But it's already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face. Quartz reported. And they aren't even twins.
“We may expect too much from bio-metrics.” 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.
“It's good to see bio-metrics being used more,” Jain told CBS News, “because it adds another factor for security.
| A．But despite its popularity, experts warn that bio-metrics might not be as secure as we'd imagined |
| B．Security experts don't think it absolutely necessary to use biometric technology. |
| C．But using different security measures is the best defense. |
| D．Now, this type of technology might not be far away. |
| E．If a person's biometric information is stolen, that could have extremely serious results for him. |
| F．The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million. |

【推荐1】We all know cameras. But have you heard of Google's new camera? It is a small, smart device, called Clips. It comes with a case that has a clip (夹子), but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photographs out of your hands so it can capture moments on its own.
This roughly 2-inch by 2-inch camera , with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smart phone.
Onboard the Clips device, it uses machine learning algorithms (计算程序)to help capture scenes. Those algorithms include face recognition. "Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces. " said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved training it to know what happiness looks like. The Google team also trained it to recognize what not to shoot-like when a child's hand is over the camera, or if it is thrown in a dark purse.
The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.
Did people think it was strange? Yes, but Payne said nobody need worry about safety. A green light on the front shows that the device is on. Besides, it is not connected to the Internet.
"This product is only possible because technology has advanced." Payne said. It was only in the past year that they could squeeze the technology down into a device this size. "Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps." He added.

【推荐3】Do you often lose things? Don’t worry. Now a new tool, which can be connected to any object you might lose, may be the way to solve your problem. The Tile, a small square linked up to your iphone or ipad by means of Bluetooth, lets you see how close you are to your missing item, within a 50-to-150-foot range (范围). If the item goes out of your phone’s 150-foot range, it can still be found on other smart phones with the same app.
When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object — a dog, for example, or a stolen bike — go out of your own phone’s 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.
Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn’t to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads.
