| 内容記述 | In recent years, fraudulent activities such as acquiring a large number of accounts using an automatic program called a bot for Web services have become a problem. To prevent such problems, a Turing test method called CAPTCHA was developed to distinguish between humans and bots. In this research, we focused on the problem that the conventional CAPTCHA method does not fit well with mobile devics and impairs user convenience and improved the easy-to-use dynamic CAPTCHA suitable for mobile devices and examined its practicality. In order to compare the previous study [2] [3] with the improved CAPTCHA, a control experiment was conducted on a mobile device. As a result of the experiment, it was found that the success rate of human beings on the mobile device of CAPTCHA-A is relatively high, and the success rate of CAPTCHA-B is low. It was found that the required time needs to be improved for stabilization. As a result of conducting a questionnaire survey using SUS, the proposed CAPTCHAA and CAPTCHA-B could not exceed the average score, but CAPTCHA-A was able to exceed the SUS evaluation value of CAPTCHA-3. As a future task, it is necessary to improve the system so that it can be used by many people. In addition, we must verify the attacks by bots. | |||||
