    摘要: Information hiding has been an important research topic for the past several years. Techniques to solve the problem of unauthorized copying, tampering, and multimedia data delivery through the internet are urgently needed. Today’s information hiding techniques consist mainly of steganography and digital watermarking. In this paper, we shall focus on the digital watermarking and propose an improved version of the integer discrete wavelet transform (integer-DWT)-based watermarking technique proposed by Chang et al. [17]. Our method is able to achieve ownership protection. First, the original image is performed with the Discrete Wavelet Transformation (DWT) and embedded with the watermark in the HL and LH blocks associated with an embedding rule. The experimental results show that the proposed approach indeed produces better results than the compared method in terms of the quality of the stego image, the extracted watermark with or without attack, and time efficiency.
