How To Set up Android Face Recognition

There is no absolute yes or no answer as to whether or not your device should require a password or security check to use it.

Many of us are fine leaving our home computers without this check, but it is worth noting that many important websites like Facebook or Amazon can be easily logged into by anyone simply because the account information is often stored in our web browser.

Also, the more functional our smartphones become, the more sensitive information is stored within them.

According to www.lifewire.com, knowing how to set up android face recognition on your phone or tablet allows you to unlock your device quicker while still protecting it from prying eyes. These steps provided below, will help in improving the accuracy of Google Trusted face on smartphones.

How to unlock an android device with face recognition

To set up smart lock so you can unlock your device with face recognition:

Navigate to your device’s settings menu.
Tap security (or security and location in some versions of Android).
Tap smart lock.
Enter your password, PIN, or pattern.
Tap trusted face.
Tap set up, and then tap next on the following screen.
Hold your device in front of you and position it so your entire face is inside the dotted circle, then hold the device still as the white dots turn green.
Tap next and done.
The next time your device locks, notice the silhouette icon at the bottom-center of the screen. This indicates your camera is searching for a face. If it recognises you, the icon will become an open padlock. Swipe it to unlock your device.
You are done!
How to improve android face recognition

Features such as facial hair, glasses, and piercings can confuse face identifiers. Lighting can also affect how your device perceives you. After setting up smart lock, you might as well optimize your device’s face recognition capabilities:

Go back to settings > security > smart lock.
Tap trusted face.
Tap improve face matching.
Follow the on-screen instructions.
Subtly change your appearance, or simply find different lighting conditions, and take another picture.
You can repeat this process to help your device better recognise you and unlock faster.
How to disable trusted face

If you ever want to disable Trusted face, navigate to settings > security > smart lock > trusted face and tap remove trusted face.

How reliable is trusted face?

While the iPhone X boasts the powerful Apple face ID feature, android uses the less reliable trusted face technology. Face recognition systems rely on different methods like the thermal imaging, 3D face mapping, and skin surface texture analysis to identify distinctive facial features. Although face recognition systems occasionally fail to recognise someone, they very rarely misidentify a person.

That said, trusted face can be tricked if someone holds a picture of you in front of your device’s camera. Apple has taken measures to prevent such workarounds, but no face recognition technology can distinguish between identical twins. For these reasons, enabling smart lock can actually make your device less secure.

On android devices, fingerprint and voice recognition are more secure options for locking and unlocking. Nonetheless, anyone who knows your password, PIN, or pattern can still access your device even if you have these extra features enabled. Smart lock is really more of a convenience than a security feature, but it can come in handy when you need to access your phone quickly. If you are worried about your privacy, consider downloading some security apps for android.

More android face identifier apps

Face recognition technology has more uses than unlocking your device. For example, some law enforcement officials now use an app called FaceFirst to identify criminal suspects. Other facial recognition apps like iObit Applock and FaceLock improve upon the built-in capabilities of trusted face.

Android tablets and phones with face recognition

Today, most smartphones have some face recognition capabilities. On top of trusted face, some android phones come with built-in systems that enhance the face recognition feature. Consult your device documentation for additional information on setting up face lock. If you want to purchase a new device with reliable face recognition, your best bet is an iPhone or iPad since iOS is more secure than Android overall.

Use a Third-Party Lock Screen

If the built-in options are not enough, there are many third-party apps to choose from, such as Solo Locker. Apps like these offer alternate ways of locking and unlocking a phone, viewing notifications, and the ability to customize background images and themes. Solo Locker can use your photos as a pass code, and you can design a lock screen interface.

If you download a lock screen app, disable the android lock screen in the security settings for the device. If you uninstall one of these apps, re-enable the android lock screen.

How facial recognition really works

Computers use face scanning software to identify a person by mapping their facial features and comparing that information with a database of faces.

According to www.lifewire.com, facial recognition technology is quickly becoming the most secure and reliable tool for user authentication.

How does face scan technology work?

Facial recognition systems use a number of measurements and technologies to scan faces including thermal imaging, 3D face mapping, cataloging unique features (also called landmarks), analysing geometric proportions of facial features, mapping distance between key facial features, and skin surface texture analysis. Facial recognition technology falls under the category of biometrics, or the measurement of biological data. Other examples of biometric technologies include fingerprint scanning and eye/iris scanning systems.

Uses for facial recognition technology

Facial recognition software has a variety of applications, but it is most commonly used for security and law enforcement purposes. Airports use facial recognition software to search for individuals suspected of crimes and also to compare passport photos with in-person faces to confirm identities.

Law enforcement agents use facial recognition software to identify and apprehend people who commit crimes. Several states use facial recognition software to prevent people from getting fake identification cards or driver’s licenses. Some foreign governments have even used facial recognition technology to crack down on voter fraud.

Limitations of facial recognition

While face recognition programs can use a variety of measurements and types of scans to detect and identify faces, there are limitations:

Poor resolution images and poor lighting can reduce the accuracy of face-scanning results.
Different angles and facial expressions, even a simple smile, can pose challenges for face matching systems.
Facial recognition loses accuracy when the person is wearing items like glasses, hats, scarves, or hairstyles that cover part of the face. Makeup and facial hair can also pose issues for face detection programs.
Facial scans don’t necessarily connect with a profile, meaning that a scan of a person’s face may not be useful if there are no photos of them in an accessible database. Without a match, the identity of the person behind the face scan can remain a mystery.
Concerns over privacy or security can also pose limitations for how facial recognition systems are used. For example, scanning or collecting facial recognition data without a person’s knowledge and consent violates the Biometric Information Privacy Act of 2008.

Facial recognition technologies can be exploited for nefarious purposes. For example, facial recognition data that positively matches online photos or social media accounts could allow identity thieves to gather enough information to steal a person’s identity.

Facial recognition use in smart devices and apps

Facial recognition is a growing part of our everyday lives through devices and applications. For example, the Facebook facial recognition system, DeepFace, can identify human faces in digital pictures with up to 97 per cent accuracy rate.

Apple has also added a facial recognition feature called Face ID to the iPhone X. Face ID is expected to replace Apple’s fingerprint scanning feature, Touch ID. It stores a mathematical representation of your facial scan in a secure location on the device itself; the information does not get copied or stored on Apple’s servers.

Face ID uses depth perception and infrared sensors to ensure that the camera is scanning your actual face and not a photo or 3D model. The system also requires your eyes to be open, which prevents another person from unlocking your phone while you are asleep or unconscious.

Apple has cautioned that identical siblings (twins, triplets) would be able to unlock each other’s phones. Even without an identical sibling, Apple has estimated that there is approximately a one-in-a-million chance that the face of a complete stranger will have the same mathematical representation of their facial scan as you do. Children under 13 are not good candidates to use this technology because their faces are still growing and changing shape.
