Outline of Final Research Achievements

In this research, we have aimed to prevent spy-photo with smartphone by using LED lighting signal. From experimentations, effective situations can be built from proto type environment. Furthermore, novel flicker noise-based prevention system is developed for extracting place and time information from spy-photo.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,更衣室やトイレ等の場所に導入すれば,悪意のある第3者による盗撮行為を減らすことが可能になる.また,撮影された動画をインターネット等にアップロードされた場合でも撮影画像から位置を含む場所や時間等の情報が得られるため犯罪者の特定につながりやすい.尚,この際に主にコントローラを設置して既存の照明を利用することが可能である.
