A new robust and non-blind digital image watermarking scheme based on integer wavelet transform

摘要

Watermarking is a process that secret information is embedded in the media for copyright protection. These systems according to application need specific features. Which robustness, imperceptibility and security are the most important characteristics? In recent years, simultaneous increasing the value of these features is major goals of researchers. In this paper, we proposed a new method based on integer wavelet transformation and predictable random number sequence can be used in copyright protection. That watermark inserted in LL sub-band of the integer wavelet transformation. The result of the implementation and PSNR and NC calculations shows that the proposed approach has resistance against common attacks and transparency better than the compared similar methods.
