Abstract

Recently, most methods of data hiding focused on perfect embedding. On the contrary, the watermarking techniques concentrated on better extraction. In this paper, the schemes of reversible data hiding and watermarking extraction are combined for color images watermarking. As a result, an improved Prediction-error (PE) watermark embedding based on Integer Haar Discrete Wavelet Transform (IHDWT) is proposed. During the extraction stage, two-dimensional Principal Component Analysis (2DPCA) is applied for blind watermark extraction. The experimental results have shown that our method can embed and extract the watermark accurately and can still resist against various attacks efficiently.
