Dual Image based Reversible Data Hiding Scheme using Color Image for High Embedding Capacity
Dual image based reversible data hiding scheme has been studied vigorously to increase the embedding capacity of
secret data and to obtain good image quality. Lu et al. proposed a reversible data hiding scheme using CFS (Center Folding
Strategy) method based on dual images for high embedding capacity and low image distortion. We have investigated the
reversible data hiding scheme based on color image and found an improved method to increase embedding capacity of secret
data. In this paper, we propose an improved dual image based reversible data hiding scheme which increases the embedding
capacity of secret data by using characteristics of the color image. Experimental results show that the proposed scheme has a
higher embedding capacity while maintaining image distortion that is not detected by human vision.
