Improvement of Imperceptibility Evaluation Method and Security of Non-Blind Digital Image Watermarking Technique

Authors: Jon Tae Bom, Kim Kyong Jin, Ri Hyo Il, HyonChol Kim, Jang Un Ju

This paper presents the new digital image watermarking technique that has high imperceptibility and robustness against various geometric image attacks such as rotation attack and cropping attack using discrete wavelet transform (DWT) and singular value decomposition (SVD).In this paper, watermark logo is scrambled by 3D Arnold’s cat mapping and Chebyshev mapping, then security of watermark logo is realized.And control parameters of chaos mapping are encrypted bythe proposed quantum resistant encryption technique.Also in this paper, the suitable color image similarity evaluation method and the suitable embedding scaling factor using the relative vision characteristic of human are defined,computed and used in evaluation of imperceptibility.
