Abstract: Each node device has a sensor data saving information list storage section for storing a sensor data saving information list indicates a proper node device for saving each of sensor data among node devices according to an attribute of the sensor data. A sensor data arrangement section transfers each of the sensor data saved in sensor data storage sections of the node devices to the proper node device for saving the sensor data based on the sensor data saving information list.

Abstract: A computer apparatus makes an information acquisition request to any of multiple node devices. Each node device has a sensor data search section for searching a sensor data storage sections of the multiple node devices for a sensor data according to the information acquisition request and acquiring the sensor data and an information transmission section for transmitting the sensor data acquired by the sensor data search section or calculation result data acquired on the basis of the sensor data to the computer apparatus.

Abstract: The present invention is to protect the right of portrait or privacy of people other than a specific person, and to enable easy recognition of information other than the face of the specific person and the situation around the specific person. Images videotaped by the surveillance cameras are captured in the computer, face images are detected therefrom, and the detected face images are compared with the face image of a specific person registered in the storage device. As the results of the comparison, when these face images do not match with each other, a mosaic process is applied exclusively to the detected face images to protect the privacy of the people other than the specific person, whereas the mosaic process is not applied to the parts other than the faces, such as dress and baggage, thereby keeping them as they are. When these face images match with each other, the face image of the specific person is not applied with the mosaic process, thereby keeping his or her face and remaining parts as they are.
