In this study, we have developed and proposed a secure and useful authentication method to resist 'shoulder surfing' attacks for smartphone. This authentication method uses rhythms at the time of touching panel of smartphone for individual identifications. In this article, we described results of an experiment and evaluated the proposed method with rhythms. In the experiment, we divided experiment collaborators into two groups by their years of experience for musical instruments like a piano, guitar and so on. At first, we measured rhythms of each groups, and then we analyzed these data with SOM (Self-Organizing maps). In the 1st group as longer experience, the precision of the authentication was 98.9%, in the 2nd group as shorter experience, the same was 94.9%, 4.0% higher than 1st group.
