Face On Mobile? It may interest you to know that there are lots of smartphones in the market that features facial recognition security. So to find out how the feature works, you have to read to the end.
However, Face on mobile recognition technology is now a staple of smartphone security, including the trust old PIN and increasingly elaborate fingerprint scanners. Although not necessarily more secure than a fingerprint scanner. But, biometric ideas like facial recognition tend to be faster and more convenient to use, that’s why lots of people prefer it more.
There are lots of face recognition on mobile tech out there to choose from, this article will be unveiling them. I believe you will make a good choice from the list.
Face On Mobile
Check out the following options, how they work, and what they mean for security.
Apple Face ID and 3D scanning
The Apple company unveiled its new Face ID technology as part of its iPhone X launch, the first 3D face-scanning tech in a smartphone. The 3D scanning is designed to map out a user’s entire face in a highly secure manner. However, it does not just rely on the phone’s familiar front-facing camera, there are actually lots of sensors crammed onto that strip at the top.
Moreover, the iPhone X features an array of sensors designed to capture details of your face.
How does it work? For beginners, it uses an infrared floodlight to illuminate your face, which will work regardless of your surrounding lighting conditions as it’s outside of the visible spectrum. Then, a secondary 30,000-point infrared laser matrix is beamed out, which reflects off the floodlight. So instead of taking a picture of this infrared light, a special infrared camera detects subtle changes in the matrix point reflections as your face makes minute movements, which lets the camera capture very accurate 3D depth data.
Infrared Assisted Face Unlock – Face On Mobile
This Infrared Camera is a more secure option to detect faces, instead of a regular camera that operates in the visible spectrum. It requires extra hardware in the form of an IR emitter and a camera capable of detecting the IR light, but this doesn’t have to be massively expensive.
However, this method is just like taking a 2D image but in the IR spectrum. Which makes it much harder to dupe with a simple picture. Thus, the use of IR also ensures that the feature works consistently regardless of the lighting conditions. It involves looking at the user’s whole face. This technique is certainly faster, but not necessarily more secure.
Samsung Intelligent Scan
Samsung Intelligent Scan is another amazing Face recognition tech on mobile. The company was the first to pack advanced facial recognition technologies into a top-tier flagship with iris scanning technology inside the ill-fated Galaxy Note 7. The feature is found in the Galaxy S8 and new Note 8, which forms part of Samsung’s security suite alongside a broader face recognition system and fingerprint options.
How does it work: the iris scanning executes its works by identifying the patterns in your irises. Just like fingerprints, these are unique to each person, making them very difficult to replicate. However, to achieve this, Samsung’s latest flagships are embedded with an infrared diode that illuminates your eyes regardless of the surrounding lighting conditions.
This light wavelength can’t be detected by a regular front-facing camera, so a special infrared narrow focus camera then captures the detailed iris information. This image is then stored and processed locally on the mobile device.
However, the Tech combines iris and facial scanning techniques together to improve accuracy and security. It works much better in low light. The facial scanning part of technology simply builds up a 2D image map of your face, which is common to all Android phones. The aim is to combine the infrared iris scanning part with this 2D image to double up on the security layers.
Android’s basic facial recognition
Android has been able to unlock your phone with your face ever since, Almost all smartphones make use of this technology today, as an alternative to unlocking your phone with a PIN or fingerprint.
One disadvantage about it is that it only relies on your front-facing camera and a 2D facial recognition algorithm, which makes it cheap and easy to implement. However, these two features are all Android needs to create a picture of your face and features.
So, as this is just a 2D image a simple photograph of you is enough for someone else to fool the System and unlock your phone.
The quality of the front camera is a determining factor, as is the complexity of the algorithm used to extract facial details.
