Abstract Abstract In our previous study, we collected a touch operations history when 40 subjects performed basic operation, text browsing, and In our previoususing study, collected a touch operations historyhistory, when 40 basic operation, text browsing, and web browsing ourwe Android application.

The results identification pinch, and then identified subjects using some machine learning algorithms. The results showed that user identification rate reached about 95% for basic operation and text browsing.
