Abstract: PURPOSE: A watermarking and encryption technique for resolution improvement, forgery prevention and contents spread prevention in a surveillance camera system is provided to realize high resolution image restoration and watermarking while preventing image quality deterioration of an important area like a face by selectively watermarking a non interest area. CONSTITUTION: A watermarking and encryption technique for resolution improvement, forgery prevention and contents spread prevention in a surveillance camera system improves resolution of a human face up to a level that subjective determination is possible in the surveillance camera system. Watermark information is selectively inserted into a non interesting area by selecting a area when invasion is generated in the surveillance camera system. In the surveillance camera system, a watermark is selectively inserted into only a specific frame by watermarking time information. A watermark is selectively inserted into only a specific part of a GOP(Group of Picture) in the surveillance camera system. A monitoring image is and stored by selectively encrypting only a part that a user wants.
