Abstract :
In this paper, an image hiding scheme based on 3D skew tent map and wavelet transform is proposed. One 3D skew tent map with three control parameters and one coupled map lattice are utilized to encrypt the secret image which will be imbedded in one host image. The encryption scheme consists of generating a chaotic orbit by the skew tent map to scramble the pixel positions and yielding a random gray value sequence by the coupled map lattice to change the gray values. The encrypted secret image and the host image are transformed by the wavelet transform and then are merged in the frequency domain. Experimental results show that the proposed hiding scheme is robust against malicious attacks like cropping, noising, etc.
