上周蘋果發布會的頭號新聞當屬iPhone X問世，尤其是可用面部解鎖iPhone的新功能。沒錯，以后用戶不用輸入密碼，只需看一眼iPhone就能解鎖了。

雖然不是新科技（一些三星的手機已有面部解鎖功能），但蘋果對該技術全力投入。而且蘋果跟競爭對手不一樣，宣稱蘋果手機上的面部解鎖功能FaceID是絕對安全的，用戶可以放心使用。

聽起來不錯，但我肯定不會去用。

我在一場辯論中和別名“你只活一次”的同事羅伯特·哈克特解釋過，Face ID確實是炫酷新科技，但潛在風險也很高。

其中一個原因是，我對蘋果宣稱Face ID極其安全不太相信，好像萬無一失一樣。事實上，已經有黑客在Twitter上發帖放話：“游戲開始了。”

“黑客/網絡安全圈對破解Face ID‘非常’興奮。”

這還不是我最擔心的。我是怕用上Face ID之后，警察、邊檢人員、走私販、嫉妒的愛人之類更容易侵入我們的手機。

目前其他人想隨意打開手機還比較難。要么得知道解鎖密碼，如果啟用了指紋識別功能Touch ID，就得按下指紋才能打開。

而一旦啟用Face ID，任何人只要把手機對準機主就能解鎖。對小偷來說iPhone X吸引力增加了，因為就算手機鎖定了，他們大可對準機主解完鎖再從容溜走。

另外就是警察執法，當然了，法律要求警方得有搜查令才能翻查個人手機。但如果解鎖手機太容易，很多警察很可能忍不住直接將手機對準嫌犯開機，然后宣稱手機已經是開機狀態。而且，美國憲法第四修正案已規定了一些無需搜查令就能翻查手機的豁免情形，尤其是在邊檢搜查時。

總而言之，雖然Face ID既酷炫又便利，但手機里保存了大部分重要的個人信息，例如電郵、照片、銀行應用等等，隱私泄露的風險太高了，所以我堅決不用Face ID。（財富中文網）

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.
