Data hiding in encryption–compression domain

Abstract This paper introduces a robust and secure data hiding scheme to transmit grayscale image in encryption-then-compression domain. First, host is transformed using lifting wavelet transform, Hessenberg decomposition redundant singular value decomposition. Then, we use appropriate scaling factor invisibly embed the of watermark into lower frequency sub-band image. We also suitable improve security Additionally, de-noising convolutional neural network performed at extracted mark enhance robustness scheme. Experimental results verify effectiveness our scheme, including embedding capacity, robustness, invisibility, security. Further, it established that has better ability recover concealed than conventional ones low cost.
