Abstract
Abstract A reliable medical image management must provide proper security for patient information. Protecting the medical information of the patients is a major concern in all hospitals. Digital watermarking is a procedure prevalently used to secure the confidentiality of medical information and maintain them, which upgrades patient health awareness. To protect the medical information, the robust and lossless patient medical information sharing system using crypto-watermarking method is proposed. The proposed system consists of two phases: (i) embedding and (ii) extraction. In this paper, we securely share three types of patient information, medical image, electronic health record (EHR), and face image from one hospital to another hospital. Initially, all the three inputs are encrypted and the information is concordant. In order to enhance the robustness of the crypto-watermarking system, the obtained bit stream is compressed, and the compressed bit streams are embedded into the cover image. The same process is repeated for the extraction process. The experimentation result is carried out using different medical images with EHR, and the effectiveness of the proposed algorithm is analyzed with the help of peak signal to noise ratio.

Summary
During the last few years, the medical information of the patient is transferred from one doctor to another doctor for better health solution and treatment. Diverse possibilities of threat that severely affect its authenticity, integrity, and confidentiality are instigated by the transmission of medical data over an open communication channel [6]. The process of embedding an imperceptible and detectable mark in digital content such as an image to confirm copyright protection and to avert un-authorized access is declared as digital watermarking [6, 8, 15]. A dedicated communication standard known as digital imaging and communications in medicine is used to exchange electronic patient record (EPR) between hospitals. The significant security requirements with EPR data exchange through open channels are confidentiality, authentication, integrity, and availability
