Even if some attacker snitches someone's smart phone, it will not do him much good if he does not know the PIN-code. At least, everything is previously thought. Researchers from the Singapore University of Technology Nanyang created a system that correct "guesses» PIN-code phone based solely on information provided by its sensors.
The research team led by Dr. Sivam Bhasin "teach" the system and conducted tests, when people were administered a random set of 70 four-of PIN-codes on smartphones running Android. Each phone was set user application that collects data from an accelerometer, gyroscope, magnetometer, a proximity sensor, a barometer and the environmental illuminance sensor.
Learning algorithm of software to analyze the data by comparing the sensor readings with specific numbers that press the screen keyboard. When a man holds the phone and enters the PIN-code, the phone orientation in space, for example, when you press "1" or "9" is different. Also, when you press "1" right thumb will block more light than when you press "9".
When the system has been instructed to guess the four-digit PIN-codes, based only on the sensor response, matching accuracy was 99.5% (with three attempts). Bhasin believes that it is possible that people can unknowingly download onto your phone malware that uses this technology.
Once access to the user the PIN-code phone sensors and decryption program will give information to someone who can unlock this phone. In order for such a scenario was impossible Doctor offers to mobile operating systems limited access to the phone's sensors, and users can grant permission only to trusted applications.
Those who in the coming year would be desirable something new, it is worth paying attention to flagship smartphone, which will appear in 2018.
