Pattern lock Android is suitable for the button after the screen. It is very easy to break – dobreprogramy

Popular among Android users, the protection mechanism Pattern-Lock (locking scheme) is very easy to break. Just five attempts in 95% of cases to unlock the device. Interestingly, the more complex the pattern we will use, the easier it is to break.

On the screen with the included Pattern and Locke we see the set of points between which you have to swipe. If we drew the figure coincides with the figure, as we previously determined, device will be unlocked. In addition it must be the fact that we can make only five attempts. If they are unsuccessful, your smartphone or tablet will be locked.

Experts from Lancaster University, the Chinese University Północnozachodniego and University of Bath proved just that without any problems you can break this protection, and fit in the five samples. All he needa is a camera and software for image recognition. It is sufficient to record the user of the device when unlocking and subjected to video processing in the above-mentioned software. Depending on the position of the fingers relative to odblokowywanego the device will create it’s most probable models unlock Pattern Lock.

so that the thief will be to get the victim in a cafe, bus or anywhere else, and then stole her smartphone. The attack works because regardless of the recorded video screen appears odblokowywanego device. The thief can use the camera in your smartphone – in this case, the maximum shooting distance is 2.5 meters – or d-slr. In the latter case, it is possible to remove even nine meters.

during the tests in the first approach the researcher received all but one of the devices blocked a difficult standard to 87.5% of devices protected by standard moderately complex and up to 60% of smartphones and tablets, protected by the Etalon angle. Greater ease in communication and the breaking of more complex models, researchers explain that they leave to the algorithms, the smaller the field for interpretation.

the authors of the study draw attention here to several problems. The first is the fact that Pattern Lock is used 40% of owners of devices with Android. Another problem is the tendency of people to use identical security on many devices. And the third problem, noticed it a paradox that more complex patterns easier to break.

once more confirms so many of us the truth that has still not invented anything that could replace traditional passwords. So if You want safety, replace the pattern lock strong password.
