A study by the University of Lancaster, in the northwest of China, and the british University of Bath found that the “Pattern Lock” (lock pattern) can be discovered with ease after five attempts.
The research of these institutions shows that criminals can break the pattern lock on five attempts with a video recording and specialized software.
But how does this happen?
The specialized portal Phys explains that it is enough to film covertly the owner of the phone so that subsequently the attacker to use a tracking software that succeeds in deciphering the movements of the fingertip. The algorithm creates a number of patterns to unlock the device, which is achieved in less than five attempts.
The scientists tested this system with 120 unique patterns and were able to find out more than 95 percent in the first five attempts.
The patterns more complex, with more lines between points, they become contradictory in the most easy to guess because they help the algorithm to reduce the options.
Many people tend to use complex patterns to protect their devices, and also for financial transactions are as important as the on-line banking and shopping because they think that this is a safe method of protection, explains the principal investigator, dr. Zheng Wang.
But Wang warns: “Our findings suggest that the use pattern lock to protect sensitive information in reality could be very risky.”
