简介
With the rapid evolution of digital video communication, the field of steganography has gained more attention. Video steganography has vital advantage over other steganographic techniques due to its utilization of video as the cover medium for data hiding. In this paper the advantages of using live video as a cover medium for steganography is explored. This paper presents an adaptive steganography which uses live video as cover medium. The proposed method uses content analysis and frame heterogeneity to dynamically select several steganographic techniques. Live frames are processed by initially applying Canny edge detection, yielding an edge map. Edge density is then calculated, enabling the identification of smooth frames. Depending on the calculated edge density, the algorithm chooses between Canny and Sobel edge detection techniques to adapt to diverse content complexities. Additionally, each …
