Privacy Protection Technology in Video Surveillance System

Since the increase of terrors and crimes, the demand of the video surveillance system is increasing. The video surveillance system has been operated for public interest by the police and local government. However private information such as faces or behavior patterns can be recorded in CCTV, it may cause the invasion of privacy. This paper proposes a video surveillance system that satisfies both functions of privacy protection and surveillance. The proposed system operates multiple surveillance cameras with a single RFID system. The RFID system is used in order to recognize internal or external personnel of object at entrance and cameras are used to extract features such as height and clothing-colors of the object. The proposed system can reduce invasion of privacy by intensity of scrambling according to access levels. Based on the experimental results, we are able to confirm that surveillant can classify personnel information fast and exactly in the display.
