The recent advances in digital medical imaging and storage in cloud are bringing about more demands for efficient and secure image retrieval and management. Typically, medical images are very sensitive to changes where any modifications in its content may bring about an erroneous medical diagnosis. Therefore, securing medical images is a very essential process and the major task is, the medical image must maintain their sensitive contents at the time of reconstruction. The proposed methodology executes a secure image encryption and search of medical images proficiently over encrypted image database without leaking any sensitive data. It also ensures medical data integrity by introducing an efficient recovery mechanism on ROI of the image. The proposed scheme obtains recovery information about the image from the ROI of the medical data and embeds it in the RONI region using IWT transform which act as a reversible watermarking. If any alterations or tampers are caused to ROI at the third-party end, then it can be identified and recovered from the obtained recovery data. Besides, the model also executes a Copyright protection scheme to locate the authorized users, who illegally duplicate and distribute the retrieved image to unauthorized entities.

云中数字医学成像和存储的最新进展带来了对高效，安全的图像检索和管理的更多需求。通常，医学图像对变化非常敏感，其中其内容的任何修改都可能导致错误的医学诊断。因此，保护​​医学图像是非常必要的过程，其主要任务是，医学图像在重建时必须保持其敏感内容。所提出的方法执行安全的图像加密，并在加密的图像数据库上熟练地搜索医学图像，而不会泄漏任何敏感数据。它还通过在图像的ROI上引入有效的恢复机制来确保医学数据的完整性。所提出的方案从医学数据的ROI中获取有关图像的恢复信息，并使用IWT变换将其嵌入RONI区域中，该变换用作可逆水印。如果在第三方端对ROI造成了任何更改或篡改，则可以从获得的恢复数据中识别和恢复它。此外，该模型还执行版权保护方案以定位授权用户，这些用户非法复制检索到的图像并将其分发给未授权实体。
