Abstract
In Japan, the observation of children using surveillance cameras is on the rise. However, leaking of these surveillance-camera videos to third parties causes problems. Child-observation systems, using equipment such as beacons, are highly popular in Japan. In these systems, the children must carry the equipment. Hence, the equipment cost should be low. Moreover, they work only when the child passes through a particular location, such as an elementary school gate. Therefore, after the child crosses the school gate, parents cannot check the location. In addition, as most systems use simple ID numbers, there are security problems. In this paper, we propose a child-observation system, which enhances data anonymity and security, and has an advanced security function that prevents third parties from exploiting the data. As a result of experimental results of basic test which was carried out the demonstration experiment in Nonoichi city, we confirmed the child-feature information data can be transmitted in each cluster and child-feature information data can be collected to the cluster head correctly.
