Maintaining electronic patient records is the primary role for the fruitful implementation of the telehealth services in urban areas to enhance the quality of healthcare. These records frequently shared in-between professionals and healthcare centers so as to develop efficient tool(s) for accurate diagnosis purpose. However, protection of these records is a challenging task in the current era. In this article, we develop a joint watermarking-encryption- error correcting code (ECC) technique for the purpose of securing patient records. The suggested method involves three major steps as follows: 1) watermarks generation and scrambling, 2) encryption of cover and generated watermark via Paillier cryptosystem, and 3) imperceptibly embedding and robustly recovery/extraction of the watermarks. Experimental results indicate that the proposed technique offers high robustness and fulfills all watermarking needs for telehealth applications in terms of imperceptibility, robustness, capacity, and security. Furthermore, the proposed method achieves better robustness against varying attacks, and outperforms former techniques.

小波域中用于患者记录安全性的联合水印-加密-ECC

维护电子病历是在城市中成功实施远程医疗服务以提高医疗质量的主要作用。这些记录经常在专业人员和医疗中心之间共享，以便开发出有效的工具以进行准确的诊断。但是，在当前时代，保护这些记录是一项艰巨的任务。在本文中，我们出于保护患者记录的目的，开发了一种联合水印，加密，纠错码（ECC）技术。所提出的方法包括以下三个主要步骤：1）水印的生成和加扰； 2）通过Paillier密码系统对封面和生成的水印进行加密；以及3）潜移默化地嵌入和鲁棒地恢复/提取水印。实验结果表明，所提出的技术具有很高的鲁棒性，并且在隐身性，鲁棒性，容量和安全性方面满足了远程医疗应用的所有水印需求。此外，所提出的方法对各种攻击具有更好的鲁棒性，并且优于以前的技术。
