Abstract
The privacy problem is caused by various factors. First, I will reconsider to organize information and privacy and their handling in Modern. Thereby, the concept of privacy in modem Japanese society, I described that is based on the self-information control rights and relational mobility. Next, I estimated the posture of a person and created a skeleton model. And then I protected the privacy of the subject based on the skeleton model. As a result, the estimation error between the measured skeleton and the estimated skeleton model was 18 cm, and I created an image that converted natural look of the subject.
