Implementation of the Privacy Protection in Video Surveillance System

Due to increased terrors and crimes, the use of the video surveillance camera system is increasing. It has been operated for public interest such as prevention of crimes and fly-tipping by the police and local government, but private information such as faces or behavior patterns can be recorded in CCTV. When the recorded video data is exposed, it may cause an invasion to privacy and crimes. This paper analyses conventional methods of privacy protection in surveillance camera systems and applied scrambling and RFID system to existing surveillance systems to prevent privacy exposure in monitoring simultaneously for both privacy protection and surveillance. The proposed system adjusts the intensities of privacy according to access levels to reduce invasion of privacy by people who are not concerned.
