把你的脸印在口罩上，以便解锁手机

这家公司会把你的脸印在口罩上，以便您可以解锁手机

The coronavirus is a real concern right now, especially if you happen to live in a heavily-populated area and worry about potential infections. The new virus has the same symptoms as the flu and has to be diagnosed using special tests, which means anyone could be infected. Again, that’s if you live in a region where a significant number of cases have been confirmed already. There’s no reason to panic over the new virus and you won’t get it if nobody in your area has it.

冠状病毒现在是一个真正令人担忧的问题，特别是如果你碰巧生活在人口密集的地区，担心潜在的感染。这种新病毒的症状与流感病毒相同，必须通过特殊检测才能确诊，这意味着任何人都可能被感染。前提是，如果你生活在一个已经确诊了大量病例的地区。如果你所在地区没有人感染这种病毒，就没必要感到恐慌，你不会感染。

Protective gear such as masks can help prevent the spread of the virus, but it’s not a guarantee that you won’t come in contact with the virus. If anything, the use of face masks helps you protect others from your own germs. And the coronavirus isn’t the only thing spreading this season. So is the flu, which can be even deadlier than the coronavirus. One of the downsides of using a face mask is that it might make it impossible to use your phone if you rely on a face scanner system to unlock it. However, someone already thought of a clever solution to this problem: Print your face on N95 masks so that you can unlock your phone while you wear them.

像口罩这样的防护装备可以帮助防止病毒的传播，但这并不能保证你不会接触到病毒。如果有什么作用的话，那就是口罩可以帮助你保护他人免受自身细菌的侵害。而冠状病毒并不是这一季唯一的病毒。流感也是如此，它甚至比冠状病毒更致命。使用口罩的一个缺点是，如果你依赖面部扫描系统来解锁手机，它可能会让你无法使用手机。但是，已经有人想出了一个聪明的解决方案:把你的脸印在N95口罩上，这样你戴着口罩时就可以解锁手机了。

Not all face unlocking systems are made equal. Android phones used 2D face unlock for several years, which is the kind of face unlock system that you can trick with a photo. Printing the lower region of your face on the face mask will probably be enough to bypass phones that use that less-than-secure 2D face unlock technology. 2D face recognition is not safe to use with banking apps and other sensitive services.

不是所有的面解锁系统都是一样的。安卓手机使用2D面部解锁已经有好几年了，这是一种你可以用照片欺骗的面部解锁系统。在面罩上印上你脸部的下半部可能足以绕过使用不安全的2D面部解锁技术的手机。使用银行应用程序和其他敏感服务时，2D人脸识别并不安全。

Apple came up with 3D face unlock a few years ago and called it Face ID. The system maps the 3D layout of your face with the help of a sophisticated camera module while simultaneously checking for your attention (eyes open or closed) to unlock an iPhone or iPad. Others have tried to replicate Face ID, including Huawei, Xiaomi and LG, but only a few phones have 3D face recognition hardware. Google then added support for 3D face recognition to Android with the release of the Pixel 4.

几年前，苹果公司(Apple)推出了3D人脸解锁技术，并将其命名为“人脸ID”(face ID)。该系统借助一个复杂的摄像头模块来绘制人脸的3D布局，同时检查你的注意力(睁开或闭上的眼睛)，以便解锁iPhone或iPad。包括华为、小米和LG在内的其他公司也试图复制人脸识别技术，但只有少数手机拥有3D人脸识别硬件。随后，随着Pixel 4的发布，谷歌为Android系统增加了对3D人脸识别的支持。

Face ID users might already know that Face ID can quickly adapt to headgear, including hats and eyewear. The iPhone or iPad Pro will still unlock even if you’re wearing an unusual hat or have different glasses on. However, if a part of your face is covered by a somewhat large object, like a scarf or an N95 protection mask, it will fail to identify the 3D profile of your face and it won’t unlock your iPhone.

面部识别用户可能已经知道，面部识别可以很快适应帽子和眼镜等头饰。即使你戴着不寻常的帽子或戴着不同的眼镜，iPhone或iPad Pro仍然可以解锁。然而，如果你的脸的一部分被一个稍大的物体覆盖，比如围巾或N95防护面具，它将无法识别你的脸的3D轮廓，也无法解锁你的iPhone。

One way to bypass the problem is to add a secondary face to your iPhone or iPad in which you wear one of these customized N95 masks. You might fool the system into believing that’s what your face looks like. Most of your face would not be covered by anything, including your eyes and the system should work, at least in theory.

绕过该问题的一种方法是佩戴这些自定义的N95口罩，给iPhone或iPad上添加面部辅助。你就可以让系统误以为你的脸就是这样的。你的大部分脸将不会被任何东西覆盖，包括眼睛，手机就能解锁了，至少在理论上是这样。
