Several latest smartphone models are equipped with high-end security features for deterring theft, privacy intrusion and unauthorised use. Fingerprint scanning was one of the earlier security access innovations that succeeded passcodes and pattern locks. Later on, advanced technologies like facial recognition and iris scanning were incorporated into the security frameworks of new generation Android and iOS smartphones and tablets. These features are inherently different from each other with their respective pros and cons. In this article, we unpack them one by one.
Facial Recognition
Smartphone security reached new heights with the invention of facial recognition technology. It was the most advanced system in place for mobile phones until the introduction of iris scanning. Some may find it less secure and reliable than a fingerprint scan, but facial recognition is quick and easy to use. You can see this system running smoothly at facility security gates or the entrance of corporate buildings. Popular smartphone applications also incorporate technology similar to facial recognition such as the filter apps we often use. More recent mobile phone models utilise two modes of facial recognition for security purposes: Face ID and Face Unlock.
FACE ID
First introduced by Apple in 2017 through the launch of the iPhone X, FaceID replaced the previous fingerprint scanning system (also known as Touch ID). Using what Apple calls a 'True Depth' camera system, iPhones equipped with this feature project a small infrared light from the front-facing camera, which will then map out your features through more than 30,000 light points and subsequently store the information on your phone's memory. Glancing at your iPhone will easily unlock it, and neither a photo nor someone with a similar profile can fool the system. The use of infrared light means Face ID also works at night and in dimly lit settings.
OPPO recently released Find X and R17 and these models feature a variant of Face ID. Innovated with a structured light 3D scanning system, this variant uses approximately ten times more data points to map your face. The end result is maximum security that is difficult to outwit or outmanoeuvre. If you are looking for smartphones that come with Face ID technology, Apple iPhone XS, XS Max, XR and the latest models, along with the OPPO R17 and Find X, are highly recommended.
FACE UNLOCK
This feature is available in several new Android smartphone models. It uses technology similar to Face ID, but differs in that it solely relies on the phone's selfie camera. There were claims about Face Unlock saying it can be duped by photos and similar facial features. The system creates custom face models from images of your face to verify your identity and unlock your phone. While the less than complex method is not the most secure type of authentication, Face Unlock is convenient and easy with a lot of room for future improvement.
Fingerprint Reader
An evolution of the traditional fingerprint reader, fingerprint scanning uses a small camera underneath the screen to read your fingerprint. By placing a finger over the scanner, the hidden camera or sensor captures your finger pattern and matches it to the biometric data stored on your phone. Once a match has been established, the phone will unlock right away. Though not as quick to process as regular fingerprint scanners, this technology is relatively faster than facial recognition and iris scanning. High-end smartphone models like the newer iPhones, Huawei Mate 20 Pro and OPPO R17 Pro have their respective versions of fingerprint readers.
Iris Scanning
One of the latest innovations that Samsung added to their Galaxy S8 series phones, iris scanning was first introduced to the market in 2017. Iris scanning uses a small infrared LED light technology, combined with a special image filter equipped in the front-facing camera, which will then be used to capture the patterns of your iris in detail. For identity verification and unlocking purposes, this security feature is activated in conjunction with Face Unlock. Iris scanning is safe and convenient but with a few downsides; you cannot wear glasses or contacts and it takes more time to process than either fingerprint scanning or facial recognition. Both Note 9 and the Samsung Galaxy S9 series phones have iris scanning functionality, while Apple is rumoured to be developing new smartphones with said technology after they trademarked "Iris Image Engine."
Buying a Smartphone with Advanced Security Features
For your next mobile phone purchase, remember to add 'advanced security features' to your priority list. Many models have great designs and tons of interesting features. But if a smartphone does not have much to offer in terms of security, do not stop looking until you find a unit that can protect your privacy as much as your important files.
