Abstract (in Japanese) (See Japanese page) 
(in English) The advance of radio-based tracking systems extends the application of location-based services (LBS), but it also threatens users’ location privacy. We have proposed a method silent period to protect user’s privacy by dynamically switching on/off of radio. By this method, user receives privacy at the cost of communication time. Through simulation study, we noticed that user can only receives very limited privacy level in real environment if they don’t want to disturb the Quality of Service (QoS) of their application. As a result, we extend our silent period method, which is modeled as a mix, to a mix cascade. By using the extended method, user can keep its communication quality, and guarantee high-level privacy simultaneously. Through simulation and analytical study, we found that the optimal configuration of mix-cascade which depends on environment and proved the effectiveness of mix-cascade style protection method.
