Blind grayscale logo watermarking based on image fusion principles

Summary form only given. We propose a novel blind watermarking system, called XFuseMark, which hides a small visually meaningful grayscale logo into a host image (instead of using a random noise like sequence) based on multiresolution fusion principles, and extracts a recognizable version of the embedded logo even without reference to the original host data at the receiving end. XFuseMark is not only secure, i.e., only authorized users holding a private key are able to conduct the detection, but also robust against noise addition, and image compression. Extensive experiments demonstrate the practical performance of XFuseMark.
