A New Novel Fidelity Digital Watermarking Adaptively Pixel based on Medial Pyramid of Embedding Error in Spatial Domain and Robust
Digital watermarking refers to techniques that are used to protect digital data by imperceptibly embedding watermark into the original data in such a way that always remains present. In particular, digital watermarking techniques in frequency domain have been widely recognized to be more prevalent than others, but in recent years the techniques in spatial domain they are becoming generally abandoned. One of the problems in digital watermarking is that the three requirements of robustness capacity and imperceptibility, that are must be satisfied but they almost conflict with each other, accordingly there are trade-off between fidelity and robustness. In this paper, we proposed a new novel fidelity and robust watermark embedding method that satisfies the requirements and statement problem, called adaptively pixel adjustment process based on medial pyramid of embedding error applying in the falling-off-boundary in corners board of the cover image set-of-the MostSignificant-Bit-6 blind in spatial domain (APAPMPOEE-FOBCB_(MSB6)).In addition, the paper provides a study analysis and modified algorithms of previous works. Theoretically analysis of the proposed technique proves the effectiveness of the technique in the average of worst case and minimizing the number of embedding error to the half. Experimental results of the proposed technique was applied on the different benchmark of six gray scale images and two quantum of watermark bit embedded are compared with previous works and was found better. Moreover in all different benchmark of six-test-images the watermarks were extracted from watermark degrading, removal and geometric transformations attacks to an acceptable degree.
