Why Face ID is much safer than Android Face Unlock



  Face ID

Unlocking your phone with your face is the new sharpness, mainly thanks to Apple's Face ID. Android has a similar feature since 2015 named Trusted Face but it's also not nearly the same.

How does the face ID work?

Apple has a lot It's not only intuitive and accurate, but also incredibly safe. In short, it creates a 3D map of your face using a combination of infrared light and image capture. Forbes has explained this very well:

He uses infrared (IR) light to illuminate your face while you take the pictures to work day or night, outdoors or indoors. IR includes wavelengths of electromagnetic radiation (commonly known as "light") that are beyond the visible spectrum, so you will not be fooling your iPhone X's display in the dark.

In layman's terms, it uses a variety of sensors combined with the device's camera to create a 3D map as you really look – that's why it works in the dark or light, with a hat on, with or without glasses and everything in between. All this technology is the reason why the iPhone X series has a notch – there sits the hardware.

In other words, she uses so much more than just a picture.

How Trusted Face Works

In contrast, Android's Trusted Face feature (formerly known as Face Unlock) is nothing but a stored image of your face. In fact, you can easily fool it with a printed picture. This is bad.

The exception to this rule is when a phone combines Trusted Face / Face Unlock with another form of biometric verification – for example, the Iriscanner that can be found at Samsung Galaxy phones. But even then, this is only used as a security measure to unlock the phone. They can not be used to back up apps like banking software, credit monitoring apps, or other items that you can unlock with a fingerprint.

Why? Because it's not safe enough When apps accept Face ID as their actual security feature, it does not apply to Android. In fact, the APIs do not even exist for that.

Better Face Unlock for Android Comes (Probably)

Now it's clear, Google recognizes that a truly secure face-up is something people want – especially those who have used Face ID (and know how fantastic it is). On the street, it is said that Android Q – the upcoming Android version, which will be released this year – will provide a feature comparable to Face ID.

Of course it is necessary for the security of Face ID also the hardware support. IR scanning and deep mapping are prerequisites for a truly secure function. Phones that do not already own this hardware (read: almost every phone is just out) will not be compatible with its improved feature, even if they are do will be upgraded to Android Q.

It is worth noting that this was just theory at the time – a few exposed lines of code indicate represents an improved Trusted Face (which may possibly go through an update) Other name if that turns out to be true) in Android Q. We will not really know until Google announces Q, which will be much later this year.

But in the meantime, remember Trusted Face / Face Unlocking is nothing more than an amenity and does not provide real security.
