Abstract
Medical image watermarking represents a promising alternative tool regarding many security aspects such: digital rights, authenticity and integrity and content protection issues. Achieving a successful watermarking should be achieved by choosing the most significant and important patterns describing the image. This strategy should also ensure a trade off between the robustness of the watermark against attacks and the computational time both for watermark embedding and extracting processes. In this paper, an informed medical image watermarking scheme is proposed based on local binary pattern LBP. Local Binary Pattern (LBP) is an effective texture descriptor for images by providing the texture regions of interests concerned by watermarking. A watermark is built based on the significant information extracted from the host image by through the LBP descriptor. LBP image will be addressed to be embedded using a linear interpolation. Scenarios of geometric and nongeometric attacks have been realized on the watermarked images to evaluate the robustness of the embedded watermark in the extraction process. Furthermore, the obtained experiment results show the effectiveness of the proposed approach regarding the watermark imperceptibility and robustness.
