Aiming at problem that environmental factors influence on satellite remote sensing images and lead to image contrast decrease

and the existing reversible information hiding algorithm has low embedding capacity

a new reversible data hiding algorithm is proposed for image contrast enhancement and secure transmission. In order to improve the embedding rate

change the way of embedding

and gradually increase the contrast of satellite remote sensing images in process of embedding information. Experimental results show that the proposed algorithm has larger capacity and improve visual effect of image while comparing with typical reversible data hiding algorithm.
