This is what researchers at Lancaster University, University in China and University of Bath have concluded. The researchers used recorded material of several users inputting just the pattern with their finger movements. These movements were then analyzed via a special software that tracks movement via specific for this algorithms.
This software was reported to analyze the exact finger movements and based on those come up with patterns of the unlock code. The software has actually proven to be successful by around five failed attempts to enter the code for the 95 percent of the tested devices, HelpNetSecurityreports.
This, more evolved type of attack is much more undetectable than having to physically spy on someone to enter his password. And what is more, this software may be equally successful, since it also offered the correct unlock code with it’s first notification.
The Bottom Line
As a conclusion, PINs and pattern unlocks may be in most instances safe, but if you unlock your phone every time you use it, there is the exposure to such risks. This is why it is interesting to take several measures to prevent this from happening, in case you are still keen on using such patterns:
- Cover your hand movements.
- Move your fingers with fake gestures for confusion.
- Use fingerprint or other biometrical unlocks on your device, if possible.
