Computer networking and internet developments create new challenges in information security and copyright protection. In order to protect the remote sensing data and also in some cases, for information management, we can use watermarking schemes to achieve more security. In this paper, we firstly review a watermarking scheme for remote sensing applications, represented by Zhu et al. in 2013. We also explain about two problems in Zhu et al.’s scheme and in addition, we introduce two solutions for these problems. Generally, Zhu et al.’s scheme is a non-blind scheme that also does not have any attention to watermarked image quality, thus we try to represent ways in order to achieve the blind and quality-aware watermarking. Experimental results confirm that both our modifications have suitable effectiveness than original scheme whereas in practice, our modifications creates an output with embedding capacity like original scheme but it is very high quality and also blind.
