With the widespread use of the Internet, digital media can be readily manipulated, reproduced, and distributed over information networks. Therefore, illegal reproduction of digital information started to pose a real problem. Digital watermarking has been regarded as an effective solution to protect the copyright of digital media. In this paper, an improved SVD-based watermarking technique considering human visual characteristics is presented. Experimental results are provided to demonstrate the proposed approach is able to withstand a variety of image processing attacks.
Research Highlights► SVD is a good mathematical tool for watermarking. ► The watermarking scheme should take the human visual system into account. ► A good balance between imperceptibility and robustness can be achieved in the proposed approach.
