There are many ways to lock your Android phone, from simply locking with a password to using biometric methods. But who is the safest? ESET informs you about how secure or unsafe the basic screen locking methods are.
As people become more and more aware of privacy and data security, it would be reasonable to assume that protecting smartphones with some form of authentication would be self-evident. However, this is far from the truth. According to a study by the Pew Research Center, almost one third of Americans do not use any screen locking method. 
Let's take a look at the screen locking devices offered by the devices.
Patterned lock
This method allows you to unlock your device by finger-forming a pattern you created. In terms of screen locking options, the pattern method could at best be considered a mid-level security option. You can draw something as simple as the outline of an L or a more complex shape. The simpler the pattern, the easier it is for someone to copy it if they are close to you and watching your movements.
Για την ακρίβεια, έρευνα διαπίστωσε ότι απατεώνες κατάφεραν να αναπαράξουν το μοτίβο στο 64,2% των προσπαθειών που έκαναν αφού το είδα μόνο μία φορά. Το ποσοστό επιτυχίας αυξάνεται όσο αυξάνεται και ο φορές που είδαν την κίνηση. Μπορείτε να βελτιώσετε την ασφάλειά επιλέγοντας τη ρύθμιση που ορίζει το μοτίβο να μην είναι ορατό και διαλέγοντας ένα πιο πολύπλοκο σχήμα. Ωστόσο, θα πρέπει να λάβετε υπόψη ότι ένα PIN ή ένας code is generally a safer option.
PIN / password
If you've been smart and set up some protection method for your Android device, then you'll be familiar with the option to use a PIN or code, επειδή αυτή είναι η μέθοδος που ζητά η card SIM when you turn the device off and on again. Many versions of Android will allow you to set a simple four-digit code, but if you're concerned about security you should choose a PIN with more numbers.
If you want to further improve the security levels, then you should choose a code that includes letters, numbers, special characters and will consist of at least 8 or more characters. It may be harder to remember and use, but in the long run you will not regret choosing the safest method.
Fingerprint
Fortunately for some of us, the biometric fingerprint lock method is still available. You may encounter different sensors, on the device or on a key or even hidden on the screen of your device. The fingerprint lock method is considered to be one of the fastest ways to lock and unlock your mobile phone. By placing your finger on the sensor, the device will unlock in fractions of a second.
But how safe is this method? Most people find it extremely unlikely that a scammer will try to unlock a biometric lock. However, this is not unlikely. Fingerprints can be stolen from a photo or other source, even reproduced with a 2D printer, and then used to break biometric locks. In 2017, a security researcher was able to recreate the fingerprint of the German Minister of Defense from high-resolution photographs.
Face Recognition
Αυτή η βιομετρική μέθοδος κλειδώματος αναγνωρίζει το πρόσωπό σας και ξεκλειδώνει τη συσκευή σας. Πιθανά να φαντάζεστε ότι αυτή η μέθοδος είναι προηγμένη και βασίζεται σε υψηλή τεχνολογία, η αλήθεια είναι ότι στην πραγματικότητα βασίζεται μόνο στην κάμερα του κινητού σας και σε κάποιο λογισμικό. Η μπροστινή κάμερα σαρώνει μια εικόνα του προσώπου σας και μετά χρησιμοποιεί έναν αλγόριθμο αναγνώρισης για να επαληθεύσει ότι πρόκειται για το πρόσωπό σας. Η ταχύτητα της procedureIt depends on your device and the quality of the front camera.
This method is not necessarily safe and a scammer can bypass it using a portrait photo of you. To be precise, researchers did a test with 110 different smartphone devices and what they found was not at all optimistic. In general, using a biometric fingerprint lock in conjunction with a password is the safest option.
Especially characteristics per manufacturer
Some smartphone manufacturers use special features to enhance the security of their devices. These range from different levels of facial scanning to eye iris scanning. Samsung, for example, uses its own iris scanning method, which is fairly simple to set up. It also examines whether you wear glasses or not. The technology uses an infrared LED to illuminate your eyes, while a special camera captures iris patterns and the smartphone processes this information. Sounds like it's high tech, right? But is it safe? Well, a group of White Hat hackers used an infrared camera and managed to trick the first of Samsung phones that offered this feature.
Final conclusion
There are many locking options to choose from. It is always wise to choose a combination and not rely solely on one method. Undoubtedly, the safest option is a trusted PIN or a multi-character password. The following is the locking method with fingerprint scanning. Whatever you choose, it is wise to "look ahead". The security of your phone today can save you from an unpleasant headache in the future.
