In this paper, for aiming at the achievement of the system in which the users can enjoy network robot (NWR) services while protecting privacy, the access-control-type NWR service platform is proposed. The platform is composed of RFID tag platform (RFID-Tag-PF) and network robot platform (NWR-PF). The RFID-tag-PF manages user's 'who' information that is privacy information, and it offers user's only behavior and access-controlled information as 'what' information to NWR-PF. NWR-PF acquires user information other than 'who' information from the sensors and RFID-Tag-PF. Utilizing the user information, it controls the robot while changing contents according to the situation of the user one by one changed. The NWR service can be provided for the user and the user's privacy are protected, by the cooperation of both of platforms. The checkup service made by using the platform was embodied, and it was experimented in Ubiquitous Network Symposium 2007. The prospect that this system was able to enjoy serving with the sense of security was obtained from result of the questionnaire.
