iPhone X刷脸解锁虽好，但用户未必敢用

上周苹果发布会的头号新闻当属iPhone X问世，尤其是可用面部解锁iPhone的新功能。没错，以后用户不用输入密码，只需看一眼iPhone就能解锁了。

虽然不是新科技（一些三星的手机已有面部解锁功能），但苹果对该技术全力投入。而且苹果跟竞争对手不一样，宣称苹果手机上的面部解锁功能FaceID是绝对安全的，用户可以放心使用。

听起来不错，但我肯定不会去用。

我在一场辩论中和别名“你只活一次”的同事罗伯特·哈克特解释过，Face ID确实是炫酷新科技，但潜在风险也很高。

其中一个原因是，我对苹果宣称Face ID极其安全不太相信，好像万无一失一样。事实上，已经有黑客在Twitter上发帖放话：“游戏开始了。”

“黑客/网络安全圈对破解Face ID‘非常’兴奋。”

这还不是我最担心的。我是怕用上Face ID之后，警察、边检人员、走私贩、嫉妒的爱人之类更容易侵入我们的手机。

目前其他人想随意打开手机还比较难。要么得知道解锁密码，如果启用了指纹识别功能Touch ID，就得按下指纹才能打开。

而一旦启用Face ID，任何人只要把手机对准机主就能解锁。对小偷来说iPhone X吸引力增加了，因为就算手机锁定了，他们大可对准机主解完锁再从容溜走。

另外就是警察执法，当然了，法律要求警方得有搜查令才能翻查个人手机。但如果解锁手机太容易，很多警察很可能忍不住直接将手机对准嫌犯开机，然后宣称手机已经是开机状态。而且，美国宪法第四修正案已规定了一些无需搜查令就能翻查手机的豁免情形，尤其是在边检搜查时。

总而言之，虽然Face ID既酷炫又便利，但手机里保存了大部分重要的个人信息，例如电邮、照片、银行应用等等，隐私泄露的风险太高了，所以我坚决不用Face ID。（财富中文网）

The biggest news from Apple's launch party this week was the arrival of the iPhone X and, specifically, a new feature that lets you unlock the iPhone with your face. That's right: You can skip entering a passcode and access the phone just by looking at it.

While this technology is not new (some Samsung phones already have it), Apple is pushing the boundaries by going all-in. Unlike its rivals, Apple says its version—FaceID—is totally secure and says consumers can rely on it completely.

That's nice but I'm still not going to use it.

As I explain in a debate (see video above) with my colleague Robert "yolo" Hackett, Face ID is an impressive new technology but the potential risks are just too great.

One reason is I'm not convinced Face ID is as secure as Apple says it is, or that the technology can't be fooled. Indeed, hackers have already tweeted "game on."

The hacker/infosec community is *very* excited about breaking Face ID.

But that's not my biggest worry. Instead, my fear is Face ID makes it too easy for other people—including cops, border agents, muggers, jealous lovers, and so on—to get into your phone.

Right now, it's relatively hard for these third parties to get into your phone. They must either know your passcode or, if you have Touch ID enabled, force you to put a fingerprint on the screen.

In the case of Face ID, however, anyone can get into your phone simply by pointing it at you. For thieves, the feature will make the iPhone X more tempting to snatch since, if the phone is locked, they will have an easy way to open it before running off.

As for law enforcement, sure, the law requires police officers to get a warrant before searching a phone. But given how easy it is to unlock, many cops will find it hard to resist the temptation to open the phones by pointing it at a suspect, and the claiming the phone was already unlocked. Moreover, there's also a series of exceptions to the Fourth Amendment's warrant requirement, most notably in case of searches at the border.

The bottom line is Face ID is a cool and convenient new feature. But because your phone is a gateway to the most personal details of your life—email, photos, banking apps, etc—the privacy risk is too great, so I won't be using it.
