Apple's new face recognition is apple face unlocking really safe Recently, apple held an autumn conference to release three iPhones. The most concerned one is the legendary customized version of iPhone x for the 10th anniversary. Because the iPhone x uses the latest comprehensive screen, many operations need to be designed from a new perspective. Unlocking is the biggest problem. Apple's solution is face unlocking. When the human eye is open, the face can be unlocked immediately by infrared scanning. No Too many people worry, is iPhone x face unlocking really safe?

Does face Id make it easier for the police to unlock my phone?

Like touch ID, face ID raises the real issue of forced unlocking. If you're detained by the police or kidnapped by criminals, they won't be able to guess your password, but they can shake hands on your mobile phone, point it at your face, and scan it through face recognition. This is a major privacy concern, and many users don't think about it until it's too late. But there is no sign that face ID is worse than touch ID in this respect, but it still raises questions about how the system can be maintained under duress.

The good news is that face ID allows users to opt out, just like touch ID. Even if your face is registered, IOS 11's leaked firmware shows the option to disable face ID login. While it's not a perfect solution, it's as good as a touch ID and should allow privacy conscious users to solve their problems without completely avoiding the iPhone X.

One tricky question is whether you can unlock someone's phone with a face ID once the system is enabled On the stage, Schiller claims that the system requires the user's attention to function properly, such as' if your eyes are closed, if they are not aligned, they will not be unlocked. '

However, the speed of the process does indicate that face ID may shift the balance of the assistive device As you can see in our own hands-on test, iPhone x refuses to unlock as long as the subject's eyes are closed - but almost as long as he opens his eyes, the face ID can recognize, even if the camera slightly deviates from the subject's face.

The benefits of involuntary login protection will depend on the details of the face ID specific user interface, so with the launch of iPhone x, this will be another issue to note.

Is my face data compromised or stolen?

Apple has said it will not send face data to the cloud, which means your face data will remain on the phone. Every sign that apple is dealing with data in the same way as touch ID is good news. In this system, apple uses the registered fingerprint to create a hash version of the data, and then stores it on the secure enclave security chip of the mobile phone (you can read more in Apple's IOS security white paper, starting on page 7. )

Assuming Apple follows the same face ID manual, it's very difficult to extract data from the phone, and it's almost impossible to reconstruct a face from it Secure enclave is the safest part of a mobile phone, and it can even resist circuit level analysis. Researchers have begun to destroy some of these protection measures, and chips may still be the safest place on any consumer device you own. More importantly, the hashing process eliminates a large number of data, which makes it very difficult to reconstruct fingerprints or faces if the data is extracted.

This is not an absolute guarantee. Apple may always break through again in a way they haven't discussed, or hackers can make some incredible new breakthroughs. However, this looks secure compared to most of the information on the Internet accessible devices.

Will face id have racial prejudice?

Face recognition system has a long history of racial prejudice, mainly due to the lack of diversity of the database. The algorithm for matching faces will be better when more faces are recognized. As you would expect, most of the algorithms that use white face training don't work as well for identifying black, Chinese, or Indian people, which means that specific groups have higher error rates and the product is less effective. So, will face id have the same problem?

The business face recognition industry fell into this problem early, and in most cases, companies have incorporated more diverse datasets to solve this problem. We know how to solve this problem if we want to. The question is whether Apple has done the necessary work.

So far, we don't have enough information to say Phil Schiller said on the stage that the face ID team took over more than 1 billion images to train the algorithm, but that doesn't mean how many of us are part of the database, but what they look like. Like most technology companies, Apple's workforce is not as good, especially at the executive level. It's easy to imagine problems like this, especially given the tight deadlines and strict confidentiality of new products. There's a lot of racial diversity in the stage video about face ID testing, which at least shows that apple is aware of the problem, but we can't be sure until we can test the system in a strict way.

When the galaxy S8 was launched in March this year, its face recognition system was one of its main selling points, until it was found that the image of the face could be easily scanned on the mobile phone, which was a failure But Apple's system is more complex, relying on dual cameras and a series of projected infrared points to detect depth Apple's marketing video shows a three-dimensional mask used to test face IDs to prevent deception attacks, and the simple fact is that a camera with mobility should be able to detect fake faces more easily at work After all, it seems unlikely that the iPhone x will fail the photo test, but you will never know until you try it yourself.

Will Apple apply face ID to anything other than unlocking?

This is the most interesting question and the most difficult one to answer. In the near future, millions of people will be registered with face IDS, allowing apple to control powerful facial recognition tools. In the current system, the data remains on the phone, but it always changes. Hashing makes it difficult for anyone other than apple to use the data, but there are no practical restrictions on what they use, especially if they start storing information outside of a specific phone. On twitter, privacy advocates worry about the use of face ID data for retail monitoring or attention tracking in advertising. You can also imagine, as a delightful product breakthrough next year, integrating into the apple store or apple car as a way to carry the login, no matter who goes in.

At present, the company has invested heavily in the iPhone business, and today's theme demonstration is the best proof. Apple has always been committed to privacy in the past, and unlike most technology competitors, they don't seem interested in data collection and large-scale positioning of most Internet companies. However, one of the most ambitious companies in the world shows off a powerful new toy. It's stupid not to doubt what will happen next!
