Scientists at Illinois Institute of Technology have discovered a new smartphone software–Silence-Sense that can enable your touchscreen smartphone to identify you simply by the unique way you tap and swipe on the device. No matters whether you have Android or Windows powered smartphone, it is claimed to work well with any touchscreen smartphones.

The software, which provided 99% accuracy in test, has been individually developed by by Cheng Bo and his colleagues.

According to Cheng Bo, the software installed in smartphones uses the phone’s built-in sensors to record the unique patterns of pressure, duration , fingertip size and position of each user when interacting with their phone or tablet. Machine learning algorithms then turn this information into a signature that identifies the user — and will lock out anyone whose usage patterns do not match.

For demonstration purpose, a group of 100 users were told to use the smartphone’s touchscreen as they would normally, and Silent-Sense was able to identify the smartphone’s owner with 99% accuracy after no more than 10 taps. Even with an average of 2.3 touches, the software was able to verify the user 98% of the time.

However the software failed to check the owner’s identity when apps and mobile game were being played, but to provide security, it automatically switches on whenever more sensitive applications, such as email or SMS, are accessed, the researcher added.


The system’s accuracy can also be further enhanced by enabling the smartphone’s accelerometer and gyroscope to measure how much the screen moves when you are jabbing at it.
