Data Hiding in Digital Image Based on Color Difference
Abstract:
Data hiding is one of the most important ways to achieve secure data transfer. Most spatial data hiding methods will make the host image distortion and the embedded data can be detected by stenography analysis. A novel data hiding method is proposed in this paper. This method first disturbs the raw critical data, and then embedded them only into areas of color changes much in the host image. Experiments show that this method can reduce the distortion of the host image and decrease the appreciability of the embedded data.
