Abstract

Recently the protection of digital information has received significant attention within the digital media community and a number of techniques that try to address the problem by hiding appropriate information within digital media have been proposed. In this paper, a new watermarking method in discrete wavelet transform (DWT) domain is proposed. Firstly, we scrambled the watermark image based chaotic sequence and mapping to avoid the block effect. Secondly, we insert the scrambled watermark in LH₂ and HL₂ sub-band of the DWT of the host image to provide a good tradeoff between the transparency and the robustness of watermarks. The experimental results show that the embedded watermark in this way is sufficiently transparent and robust against noise and commonly used image processing methods such as Gaussian, JPEG compression, Median filtering etc.
