Abstract

In this paper, two novel transforms are defined, which are respectively called DWT-IDCT transform and DCT-IDWT transform, and then two novel watermarking schemes based on these two transforms are proposed. The proposed schemes are compared with the existing scheme based on DWT transform. Furthermore, since the defined transforms can be roundly used, the schemes themselves are compared in order to evaluate the effect of the round time to the schemes. As is shown by the comparison and analysis, the scheme based on DCT-IDWT is the most robust against the various attacks than the others, and moreover, the round time is chosen once or twice as recommendation for the consideration of robustness and computation time.
