The Digital Video Frame Obfuscation Method in Consideration of Human Visual System for Intellectual Property Protection and Authentication
This paper is to propose the digital video frame obfuscation method for intellectual property protection and authentication by using the DC component of an intra frame and the motion vector of an inter frame at digital video encoding. The proposed method is based on characteristics of the HVS (human visual system) which is sensitive at a low frequency and a middle frequency. This method makes a video signal distorted, so that the video is normally displayed only when a suitable authentication signal is used.
