Abstract
A non-secure transmission channel is considered as a major challenge in remote sensing. The commercial value of satellite imagery and the sensitive information it contains led engineers to look for different means to secure the ownership of satellite imagery and preventing the illegal use of these resources. Therefore, a blind multi-watermarking scheme for copyright protection and image authentication is proposed. The multi-watermarking scheme is based on designing two back-to-back encoders. The first encoder embeds a robust ownership watermark in a frequency domain of satellite imagery using Discrete Cosine Transform (DCT) approach. Whereas, the second encoder embeds a fragile authentication information into a spatial domain of a watermarked image using Message Digest Encryption Key algorithm. This study was conducted on DubaiSat-1 satellite imagery owned by Emirates Institution for Advanced Science and Technology (EIAST). The simulation results demonstrate that the proposed scheme is robust against many intentional and unintentional attacks. Moreover, it shows a very high ability for tamper detection.
