Privacy Respected Ubiquitous Sensor Environment

Recently, research and development of small wireless sensor nodes are active, such as Crossbow Motes and muPart . These are exploited to construct ubiquitous services by attaching on daily objects such as cups or chairs. An example service is a smart coffee maker, which drips coffee when coffee in a sensor attached cup gets cold. The sensor node attached daily object is called Smart Object (SOBJ) and the service is called SOBJ Service. In addition, the environment where SOBJ service works is called SOBJ Environment. We aim to clarify the following three points: 1) who has the access control right, 2) who has the right to see the data, and 3) how to disclose the data.
