There are several ways to lock the smartphone, with the most common PIN lock. Apart from this, Pattern Lock, Fingerprint and Face Unlock are included. In all these ways there are few ways which hackers can easily distinguish. Android's pattern lock was also hacked by hackers. Recently Apple's Face ID was also cracked.
Researchers at Nanyang Technologies University of Singapore have discovered a new method that allows lock of a smartphone to be unlocked through its sensors. Not only this, researchers have claimed that this method works 99.5 percent times and the device gets unlocked.
To unlock the PIN of the smartphone, the researchers have used six sensors in it. In this process, the researchers wanted to know the PIN of the smartphone through the sensor used in the Android smartphone and every time they tried to add a separate digit of four digits. It was done almost 70 times in which machine learning was also used to predict the zip code.
This team of researchers used the accelerometer, barometer, gyroscope, magnometer, ambient light sensor and proximity sensor given in the smartphone. In the smartphones it was tested, it has found that one of the 50 most common pins was inserted in it.
Researchers also believe that this is a lack of smartphone security. Because the use of the sensor requires permissions from the users. Most of the apps in android install this permit when you install it, which are necessary. That is, there is no shocking thing if a hacker unlocks the pin while using your sensor through an app.
Lead researcher Shivam Linguin of this project has said, "You hold your smartphone and use the key for the pin and the manner in which the movement of the phone is pressed to press 1, 5 or 9 is very different . As you use your right thumb to press 1, it blocks more light than pressing 9 'decryding this pattern through sensor and can detect hackers pin.
