Abstract
In recent years, needs of high security environment on smartphones that can be used for electronic money is desired. Therefore, we proposed the use of the biometrics to realize higher security than the conventional password. As for the biometrics, morphological features of human body such as fingerprint and iris pattern are mainly used. We focused on the key stroke certification as a technique of identifiable biometrics authentication unconsciously. Especially, the target is flick input for smart phone. We made a flick data collection program to work on a smartphone to perform basic examination. The coordinates of point touched on the screen were taken from two subjects and evaluated it. The test results show that some features which are usable for biometric user recognition. For the next step, we will try to find additional feature parameter s and compare the parameters between subjects.
