摘要

远程医疗领域的一个重要问题是先进的安全通信。数字图像水印是一种理想的解决方案，因为它可以保护电子患者信息免受未经授权的访问。本文提出了一种新的基于空间域的盲脆弱性图像水印方案，该方案将加速鲁棒特征(SURF)描述符与韦伯描述符(WDs)和阿诺德算法相结合。它为提高图像质量和时间复杂度，保证医疗数据的完整性提供了一种很好的方法。首先，利用Arnold混沌映射对水印图像进行洗牌;其次，将SURF技术应用于医学图像的感兴趣区域(ROI)，然后选择SURF点周围的块插入水印;最后，利用WDs对水印进行包层和提取。实验结果表明，该算法具有良好的图像保真度和最短的执行时间，保证了医学图像的完整性。

An Imperceptible Watermarking Scheme for Medical Image Tamper Detection

One of the important issues in telemedicine field refers to an advanced secure communication. Digital image watermarking is an ideal solution since it protects the electronic patient information’s from unauthorized access. This paper presents a novel blind fragile-based image watermarking scheme in spatial domain that merges Speed Up Robust Features (SURF) descriptor with the well-known Weber Descriptors (WDs) and Arnold algorithm. It provides a good way for enhancing the image quality and time complexity for medical data integrity. Firstly, the watermark image is shuffled using Arnold chaotic map. Secondly, the SURF technique is practiced to Region of Interest (ROI) of the medical image and then the blocks around the SURF points are selected to insert the watermark. Finally, the watermark is encrusted and extracted using WDs. Experimental results show good image fidelity with the shortest execution time to ensure medical images integrity.

期刊介绍： As information technology and the Internet become more and more ubiquitous and pervasive in our daily lives, there is an essential need for a more thorough understanding of information security and privacy issues and concerns. The International Journal of Information Security and Privacy (IJISP) creates and fosters a forum where research in the theory and practice of information security and privacy is advanced. IJISP publishes high quality papers dealing with a wide range of issues, ranging from technical, legal, regulatory, organizational, managerial, cultural, ethical and human aspects of information security and privacy, through a balanced mix of theoretical and empirical research articles, case studies, book reviews, tutorials, and editorials. This journal encourages submission of manuscripts that present research frameworks, methods, methodologies, theory development and validation, case studies, simulation results and analysis, technological architectures, infrastructure issues in design, and implementation and maintenance of secure and privacy preserving initiatives.
