Introduction of security camera system with privacy protection into a residential area

Social experiment is explained about introduction of the security camera system with privacy protection into residential area in this paper. In July 2008, this experiment by using the security camera system with privacy protection had been started into a residential area: Tsunatori-cho, Isesaki. In this experiment, the security camera system doesn’t monitor only a premise of house but also watches the road which is public space in front of the house. This system is introduced into one of several houses of residential area, there is to keep the life in the whole region. However, monitoring of public space has the risk of privacy violation. So the privacy protection function was added to prevent this risk. Because images are encrypted and saved by this function, nobody watch them without a password for decoding. Consequently, the privacy is protected because only a person owning a password can watch. Detail of social experiment using this system in residential area is explained.
