Do the eyes have it?

Today you would be a bit of a fool for not securing your phone using some form of lock protection. Now with GDPR, it is even more important to secure your data. However, it is not always clear how secure each of the methods is. Fingerprint scanners, iris scanners, face scanners and PIN, pattern, or password, do they really do the job? Plus, threats are not always from outside, what can you do to minimise the damage from a malware or cloning attack?


Unlocking your phone is something a lot of you do with a simple swipe. This is very unwise as anyone can pick up your phone and access some of the precious data you carry in your pocket each day. There are several choices, depending on your phone manufacturer, as to which unlock method you use.

The pattern  

We are not keen on the pattern method as, a greasy finger will smear an impression onto your screen and unless you wipe after every time, this is very unreliable.


The PIN is useful, as quick, and if you do not use 1234! If you can, use a longer 6-digit number. Be careful with dates as most people use one in their lifetime, it can be easy to guess.

The password

The password is more secure again if you need to make up a password, may we suggest this blog on How to set a password to assist you.

Think of Fingerprints, iris, and facial recognition as a second layer of security. Use them in conjunction with your PIN, Pattern and Password.


Most modern smartphones have a fingerprint scanner, though the recent move to the back of the device has upset a few people. The scanner set in the button on the front is most comfortable to use. They surprisingly can be fooled easily as only a portion of your finger is scanned at a time.

Iris Scan

The iris scanner is quite nifty, though it is not always easy to line up properly, so not the fastest method for unlocking your phone.

Facial Recognition

Much was made about this technology last year with the introduction of iPhone facial recognition, however, Samsung had a similar technology years before. Neither are foolproof.

Protecting your data

Once inside your phone, there are some precautions you can take to secure the data you hold. Using Samsung Knox programs mean you can hide away your banking apps behind its locks. Installing an anti-virus app is a good idea too.

Wipe your data

Remotely wiping your data is a handy way of making sure, that even if your phone is stolen, the thief cannot use the phone to access your more sensitive data. The antivirus checker we spoke of may well have a remote wipe solution too.
