Reversible data hiding techniques arecapable of reconstructing the original cover image fromstego-images. Recently, many researchers have focusedon reversible data hiding to protect intellectual propertyrights. In this paper, we combine reversible data hidingwith the chaotic Hénon map as an encryption techniqueto achieve an acceptable level of confidentiality in cloudcomputing environments. And, Haar digital wavelettransformation (HDWT) is also applied to convert animage from a spatial domain into a frequency domain.And then the decimal of coefficients and integer of highfrequency band are modified for hiding secret bits.Finally, the modified coefficients are inverselytransformed to stego-images.
