The data hiding is one of the most important subject in field of computer science, so a lot of technique was developed and modified to satisfy the optimum lend of hiding. In this research the contourlet transformation coefficients were studied to decide which of them are suitable to embed data on it a lot of parameters of the contourlet coefficients can be discussed one of them is the coefficient energy.The research covered most of the suggested events which could be met during the embedding state, one of them the size of the cover in addition to the size of the information were studied. Applying the suggested idea on different type of image with different size (cover image and the message image) shows that the coefficients with low level of energy are suitable to embedded the information, and the retrieved cover and message are so closed to the original one.Key word-image processing; data security; watermarking; contourlet.

“…In [13], we proposed a new contourlet-based image watermarking method which embeds a grayscale watermark with as much as 25% of the host image size in the 16th directional subband of the host image. Since the original image is required for watermark extraction, our method is considered to be nonblind.…”

“…Since the original image is required for watermark extraction, our method is considered to be nonblind. In this paper, we employ the method introduced in [13] with more details and some improvement in our algorithm and provide comprehensive experiments with more host images. The remainder of the paper is organized as follows.…”

We propose a new nonblind multiresolution watermarking method for still images based on the contourlet transform (CT). In our approach, the watermark is a grayscale image which is embedded into the highest frequency subband of the host image in its contourlet domain. We demonstrate that in comparison to other methods, this method enables us to embed more amounts of data into the directional subbands of the host image without degrading its perceptibility. The experimental results show robustness against several common watermarking attacks such as compression, adding noise, filtering, and geometrical transformations. Since the proposed approach can embed considerable payload, while providing good perceptual transparency and resistance to many attacks, it is a suitable algorithm for fingerprinting applications.
