Data Hiding Scheme Based on Pixel-Value Differencing in Dual Images

ABSTRACT:

Data hiding is to conceal the secret message into cover objects without distortion. In the proposed method, a new data hiding method is proposed to provide high embedding capacity in dual images. The proposed method generates two stego-images after embedding the secret bits into a cover image. A sub-block of two consecutive pixels is used to have different length of embedding bits by applying the difference value of two pixels. The experimental results show that the proposed method can have a high embedding capacity maintaining less distortion.
