With the proliferation of the use of the Internet and social media, the digital media industry has grown enormously in recent years. However, this has brought some challenges, including issues of content security and copyright violation. In this paper, we propose a fusion-based secure watermarking algorithm that we have named "FuSIW". This uses a hashing scheme, to guarantee copyright protection and authentication of RGB images. The algorithm uses the non-subsampled contourlet transform (NSCT) to create a fused watermark image. This contourlet transform (CT) and randomised-singular-value-decomposition (RSVD) based approach allows concealment of the encrypted fused watermark image in the blue channel of the cover image. Subsequently, the hash value of the cover image is inserted into the green channels of the host image. Experimental evaluation indicates that the FuSIW algorithm provides security from geometric attacks and several other common forms of attack. Simulations indicate that the proposed system exhibits improved robustness and security compared to existing methods. [ABSTRACT FROM AUTHOR] |
