In information hiding field, the robustness is the important performance. However, due to embedding a larger amount of the watermark into host signal, transparency and robustness of the watermarked image cannot be easily obtained, simultaneously. Utilizing measurement values of original image to produce hiding information block-based Compressed Sensing (BCS) theory in DWT domain, the paper presents a robust information hiding scheme for protecting digital content. When the scheme is achieved, embedding locations of the hiding information will be selected by visual features and relation of DWT coefficients between subbands LH3 and LH2 of the host image. Moreover the mechanism of JND (just-noticeable distortion) was used to adjust the embedding watermark strength. Experimental results show that the scheme is more robust compared with other hiding algorithm reported, and improves effectively the recovery quality of the hidden image.
