Make Sure Nothing Is Covering Your Face
Make sure your eyes, nose and mouth are fully visible to the TrueDepth camera.;Face ID doesn’t work if anything is covering your mouth and nose, such as a face mask. If you’re wearing a face mask,;you’ll be asked to enter your passcode automatically after swiping up.
Face ID works with many sunglasses. If you’re wearing sunglasses designed to block certain types of light, your sunglasses might be blocking the infrared light used by the TrueDepth camera. Try using Face ID without your sunglasses.
How Does Face Id Compare To Other Smartphone Facial Recognition Systems
Despite a healthy dose of skepticism when it was announced, Face ID has been a hit with users and critics. The overall consensus is that it’s very accurate, very fast, and very simple. Overall, the transition away from Touch ID to Face ID has been faster and smoother than most people expected.
It’s also proved, once again, how good Apple is at this sort of innovation. When Face ID launched there was one major phone out with this kind of technology: Samsung S8. Unfortunately, that system;has been shown to be very easy to fool, including by holding up a photograph. Because of this, the Samsung system appears to not be terribly secure. Samsung won’t allow its facial scans to approve financial transactions .

Samsung’s Iris Technology Is Accurate But Can Be Tricked
Samsung’s iris scanning technology, which started with Galaxy S8 and S8+, picked up a spot on the face to improve the phone’s security. The technology works by scanning unique patterns in your iris.
Because the iris motif is unique to each individual, Samsung declared this a fool-proof technology. Unfortunately, there are some potential faults with this scanning method as you can still deceive it by wearing contact lenses.
And despite combining 2D imaging with iris scanning in more recent versions like the S21 series, Samsung warns that using facial recognition isn’t as secure as using PINs or fingerprint scanning.
The company further advises against using this feature with online payment and money transfer platforms.
What If Someone Steals Your iPhone
According to Apple’s software engineering chief, Craig Federighi – who notably replied to an email from a developer, Keith Krimbel, who asked the company what would stop a thief from taking someone’s iPhone X , then pointing it at their face, and running off with the unlocked device – Apple made sure there were two mitigations in place: “If you don’t stare at the phone, it won’t unlock,” he said.
“Also, if you grip the buttons on both sides of the phone when hand it over, it will temporarily disable Face ID,” Federighi explained. So, squeezing the buttons on both sides of iPhone X disables Face ID.

Face Id Special Features
With the “attention aware” feature, the iPhone X knows when you’re looking at it. Face ID will display notifications and messages on the Lock screen when you look at the iPhone X, it will keep the screen lit, and it will automatically lower the volume of an alarm or ringer when it knows your attention is on the iPhone X’s display.
Make Sure That You Have Setup Face Id
In order to use Face ID, you have to set it up first. The iPhone models that support Face ID are iPhone 12 series, iPhone series, iPhone XS Max, iPhone XS, iPhone XR, iPhone X. Along with iPhones, some iPad models also support Face ID.;

iPhone Face Id Is Pretty Cool Here’s How It Works And How To Use It
Using your face to unlock your phone or tablet or buy something at the store feels like you’re living in the future.
Apple’s Face ID is used to unlock your iPhone or iPad.;
When it;launched Face ID in September 2017, Apple turned your close-up into the key that unlocks your iPhone. Since then, Apple has continued to expand the number and type of devices with Face ID, including the iPhone models of the last two years and the current-generation iPad Pro.
By transitioning to Face ID, Apple killed off its home button and fingerprint reader. The initial shock of relying on gestures to use your display;is jarring enough, but when you add in learning how to use Face ID, the rest of the nuances of using your phone can be frustrating.
My advice? After upgrading from a Touch ID-equipped iPhone, be patient. It may take a week or two to adjust to no longer using a home button, but once you get used to Face ID, you’ll forget all about it.
Before we dive into the setup process, here are the Apple devices that have Face ID, followed by a quick look at how it works.
How You Can Help Protect Yourself Against Facial Recognition
Want to protect your privacy in a world in which;facial recognition technology is becoming more common? Here are some reasons;for hope.
Tech innovation: Concerns;about facial recognition could spur innovation.
Consider this: Two universities have developed anti-facial;recognition glasses to make wearers undetectable.
The glasses the work of researchers at Carnegie Mellon;University and the University of North Carolina at Chapel Hill could be one;way to help protect yourself.
Social networks: Changing the;way you interact with social media could help protect you from facial;recognition-based privacy invasions.
For example, Facebook allows you to opt out of its facial;recognition system.
Its smart in general to be careful about what you share on social;networks. Posting too much personal information, including photos, could lead;to identity theft. For instance, you might share your dogs name or your high;school mascot. Those details might give an identity thief a clue to the answers;to your security questions for your bank or credit card accounts.
The Internet of things: Its also a;good idea to consider the so-called;Internet of Things; those;devices in your home that connect to the internet. IoT devices that use face;recognition include iPads, Xboxes, and video systems.
One possible solution? A;secure router can help safeguard your network and your connected devices, which;in turn could help protect your facial image.

Thermal Imaging Lets Facial Recognition Work At Night
One of the shortcomings of 2D facial recognition is that it relies on the visible spectrum of light. In laymans terms, basic facial recognition doesnt work in the dark. But this can be worked around by using a thermal imaging camera .
Wait a minute, you might say, doesnt thermal imaging rely on IR light? Yes, it does. But thermal imaging cameras dont send out blasts of IR light; they simply detect the IR light that emits from objects. Warm objects emit a ton of IR light, while cold objects emit a negligible amount of IR light. Expensive thermal imaging cameras can even detect subtle temperature differences across a surface, so the technology ideal for facial recognition.
There are a handful of different ways to identify a face with thermal imaging. All of these techniques are incredibly complicated, but they share some fundamental similarities, so were going to try and keep things simple with a list:
Of course, thermal facial recognition is usually used by the military, it isnt something that youll find at Khols, and it isnt something thatll come with your next cellphone. Plus, thermal imaging doesnt work well in the daytime , so it doesnt have many potential applications outside of the military.
Make Sure Nothing Is Hindering The Truedepth Camera
The front notch on iPhones with Face ID houses a TrueDepth Camera at the edges. Ensure there is no dirt or residue covering the TrueDepth Camera.
Clean your iPhone with an alcohol wipe, this will remove any dirt particles. Apart from the, make sure you are using a correct screen protector as it can also cause this problem.

Change Your Screen Protector
The Face ID uses a number of sensors that are placed in the infamous notch of iPhones. It is good to use screen protectors from authorized manufactures. Some cheap screen guards can hinder the sensors in the front notch.;
The notch contains the hardware that is a very crucial part of the Face ID. If you are having issue with Face ID in your iPhone, it is suggested to remove the screen protector and install an authentic one.;
When Does Face Id Not Work
Apple has clarified when Face ID is not working.;In that case you have to fall back on the pin code to gain access to your device.;It concerns these situations:
- The iPhone was turned on or restarted for the first time.
- The iPhone has not been unlocked for more than 48 hours.
- You have not used facial recognition for four hours or have not used the access code for 6.5 days or more.
- You have locked the device remotely.
- Face ID failed to recognize your face after 5 tries.
- You have activated the SOS function.
- Your;battery;is less than 10% charged.

Can I Also Quickly Turn Off Face Id
Another measure Apple has taken to protect you is to;quickly disable Face ID;.;If someone under threat wants to take away your iPhone, you can temporarily disable facial recognition by briefly pressing the buttons on either side of the device.;If you have to deal with the police or other authorities, you can quickly turn off facial recognition by pressing the buttons.;You can also prevent unwanted unlocking by not looking straight into the camera.;In addition to facial recognition, this also works with Touch ID.
So if youre forced to use Face ID to unlock your iPhone, but didnt have a chance to turn it off quickly, you can simply keep your eyes closed.;As a result, your face will not be scanned successfully, which will automatically disable facial recognition after two attempts.
Twins And Close Relatives
Inconsistent results have been shown when testing Face ID on identical twins, with some tests showing the system managing to separate the two, while other tests have failed. The system has additionally been fooled by close relatives. Apple states that the probability of a false match is different for twins and siblings, as well as children under 13 years of age, as “their distinct facial features may not have fully developed”.

Devices That Offer Facial Recognition
Apples iPhone X series and Samsungs Galaxy Note 8 and 9 are the most popular devices with facial recognition right now. As other companies follow suit, its estimated that over one billion smartphones will use digital 3D face scanning in the next two years. In addition to Apple and Samsung, popular devices that offer this feature include Motorola Moto G6, OnePlus 6, Oppo Find X, Huawei Honor 7X, and LG G7. These devices scan faces using a 2D scanner, iris scanner, or a combination of the two. You can also download facial recognition applications like FaceLock, which lets you access or restrict other apps using facial recognition.
As facial recognition becomes more popular, its important to research the pros and cons as you consider getting a phone with this feature.

How Is ‘require Attention’ Supposed To Work For People With Facial Quirks
Apple’s Require Attention feature means you have to be able to show the iPhone that you are aware of its scan by looking directly at it. This ensures that someone can’t just scan your face while you’re sleeping or looking away, unknowing that someone else has your iPhone. There are definitely people that won’t be able to perform the actions required for Require Attention.
Apple included the ability to disable Require Attention in the Face ID and Passcode settings. For those with issues looking directly at their iPhone, you can disable Require Attention and still use Face ID.

How Accurate Is Face Recognition
Facial recognition supporters often argue that this AI technology is necessary to protect against the greatestrisks, such as terrorist attacks and human trafficking. Regardless of such claims, facial recognition today is mostlyused for petty crimes like shoplifting or selling $50 worth of drugs.
Using face recognition – particularly for criminal prosecution – has been highly criticized as the method isprone to errors.
Errors in face recognition can be ‘false negatives’ or ‘false positives’ as explained by the EFF
“A ‘false negative’ is when the face recognition system fails to match a personâs face to an image that is, in fact,contained in a database. In other words, the system will erroneously return zero results in response to a query.”
“A ‘false positive’ is when the face recognition system does match a personâs face to an image in a database, but thatmatch is actually incorrect. This is when a police officer submits an image of ‘Joe’, but the system erroneously tellsthe officer that the photo is of ‘Jack’.”
For instance, in 2018while testing Amazon’s facial recognition software, the tool incorrectly identified 28 members ofCongress as people who had been arrested for committing a crime.
While the AI systems get better over time, the use of facial recognition remains problematic as such.
Ir Cameras Add Depth To Your Identity
While some facial recognition applications rely solely on 2D images, it isnt uncommon to for facial recognition to rely on 3D imaging as well. In fact, your experience with facial recognition probably involves a pinch of 3D.
This is achieved through a technique called lidar, which is similar to sonar. Essentially, face scanning devices,;like your iPhone, blast a harmless IR matrix at your face. This matrix then reflects off your face and gets picked up by an IR camera on your phone.
Where does the 3D magic happen? Your phones IR camera measures how long it takes for each bit of IR light to bounce off of your face and return to the phone. Naturally, the light that reflects off of your nose will have a shorter journey than the light that reflects off your ears, and the IR camera uses this information to create a unique depth map of your face. When used alongside basic 2D imaging, 3D imaging can significantly increase the accuracy of facial recognition software.
Lidar imaging is a weird concept that can be difficult to wrap your head around. If it helps, try to imagine that the IR mesh from your phone is a pin-board toy. Like a pin-board toy, your face leaves an indentation in the IR mesh, where your nose is noticeably deeper than, say, your eyes.
