Which Is Safer For Smartphone Locking: Face Detection Or A Simple Code?

Think about how much more information about us is stored on our smartphones. It can deduce your whereabouts, browsing history, banking transactions, purchasing preferences, and the names and contact information of everyone in your social circle.

What about the risk of cyber criminals and snoopers accessing your phone? I trust that your technological gadget has some privacy protection system to keep your information safe.

Surprisingly, over a third of smartphone users don’t bother to set up even the most fundamental kind of security, a 4-digit password, on their handsets. This is the kind of safety violation you should never commit.

Face scans, fingerprints, irises, passcodes, Sensors and Transducers are some methods available to protect and access our mobile devices. In comparison to other products, which ones are the safest? Which one is better to use? Keep reading, and I’ll get to each one in turn.

Regular Patterns

Instead of entering a code, password, or PIN to access their phone, Android users can instead use a pattern password. It’s the weakest form of phone security, though.

A study presented at the Sessions of the Annual Computer Security Applications Conference found that people can remember 70 per cent of the time when they see a pattern entered to unlock a phone on video for the first time.

Shoulder surfing is a standard method of password theft when an attacker watches a victim type their password secret and copy it. This study replicated this approach As repeated viewings of the film pushed this figure to 80%.h.

The authors propose a theory that visual patterns are more accessible to learn than arbitrary numbers. However, if you find yourself in a position where you have to use a design, you can take steps to make it as secure as possible, such as starting from various locations.

Patterns are the most precarious of all things. And something called selection bias can occur. “it has been seen, for instance, that users usually start from the top left corner,” says Maximilian Golla, a security researcher at the Max Planck Institute for Security and Privacy.

Facial Recognition

Most modern cell phones use some form of facial recognition software. That’s why you can unlock your phone with only your eyes. Faster than iris or fingerprint unlocking, deprived of forgoing safety.

Unluckily, the 2-D version of the biometric security gadget is so easily broken. This vulnerability has been revealed through testing on mobile devices like the Samsung Galaxy S8. A snapshot of the phone’s owner is usually enough to fool 2-D facial unlocking technologies.

If your phone supports other unlock methods, such as a fingerprint scan, PIN, or eight-node pattern, please utilize those instead of 2-D face recognition.

As a result, we get to the technology of 3-D face scanning, which is employed in the more secure facial recognition systems like Apple’s Face ID.

Visual Identification

The next generation of face recognition technology is here, called Face ID. Face ID, in contrast to Samsung’s approach, uses depth detection and three-dimensional facial tracking.

The upper display notch of the iPhone X has several extra sensors, plus an ultraviolet camera, and a flood illuminator for face complexity mapping.

When used in tandem, these sensors will flood your face with 30,000 invisible dots that will track your face in three dimensions and then use that data to create a pattern that will be securely stored on your iPhone. When you look at your phone, a facial recognition system compares your looks to what it sees.

Compared to TouchID, Apple claims that the chances of someone successfully deceiving Face ID are one in a million. In addition, Face ID is adaptive enough to handle regular tweaks. It works with any hairstyle, beard length, or headgear so that it can keep an eye on your face at all times.

Iris Detector

Iris detection is the most safe form of biometric verification since our irises are more unique than our fingerprints. This makes it the safest kind of biometric authentication currently in use. Although the technology is available on some Samsung Galaxy handsets, iris scanning can be more time-consuming because the user must gaze straight at the sensor.

Unlocking your phone easily, Samsung has started using iris detection and 3D facial recognition. For example, if Intelligent Scan fails to identify your face in low light, it will try to do so by scanning your iris; if it fails in good morning, it will try by checking your face.


Since Apple debuted its Touch ID fingerprint scanner, biometric authentication by fingerprint scan has been considered more reliable than passwords. Apple claims that the odds of someone else’s fingerprint fooling Touch ID are one in 50,000.

Currently, biometric fingerprint technologies are utilized for various purposes, including device unlocking, app authentication, and financial transactions.

A fingerprint can be lifted, and a latex copy made to fool Touch ID, but this is such a complex procedure that the average user should not worry. However, fingerprint scanners are the most secure method of unlocking a device.

As for the best method of protecting your device, it’s hard to say because everyone’s situation is different. For the time being, if you aren’t Adele or Timothée Chalamet, your fingerprint sensor or iris scanner is probably the superior security technique, if only to limit the probability that someone might learn your password or watch you type it.

As was previously said, neither biometric nor non-biometric security systems are without flaws; thus, we must make do with what we have while remaining vigilant, keenly aware of the limitations of each security approach, and patiently awaiting their inevitable evolution.
