Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, the use of personal devices for learning purposes has increased due to the GIGA School Initiative promoted by the government. However, conventional authentication methods that rely on IP addresses make their usability low when access points of devices change. In this reports, we propose a risk-based continuous authentication method that utilizes browser and network fingerprinting to continuously identify the user based on device-specific characteristics. Through preliminary experiments, we selected 32 browser-side attributes and 7 network-side attributes, and constructed a method to calculate a comprehensive score by assigning weights to each attribute. In the evaluation experiments, we confirmed that 6 out of 8 devices successfully authenticated when accessing from different network environments.The result indicates that continuous authentication of devices is possible even when the location changes.
