The future holds the possibility of hospitals sharing medical images obtained through non-invasive systems to patients remotely. The advent of cloud and the storage and deployment of medical healthcare images in the cloud has resulted in the increased need for application of Cryptographic techniques to protect them from unauthorized access and malicious attacks. The Digital Imaging and Communication in Medicine (DICOM) standard is more compatible across medical imaging instruments globally. The pixel data of DICOM images requires more privacy and security. A novel ECDS based cryptographic approach is suggested to encrypt the original DICOM image as well as the ROI pixel data extracted from DICOM images. Results computed experimentally have proved that medical image encryption via ECDH is more robust, efficient and faster than existing medical image encryption schemes.

未来医院有可能将通过非侵入性系统获得的医学图像远程共享给患者。云的出现以及医疗保健图像在云中的存储和部署导致越来越需要应用密码技术来保护它们免受未经授权的访问和恶意攻击。医学数字成像和通信 (DICOM) 标准在全球医学成像仪器之间具有更高的兼容性。DICOM 图像的像素数据需要更多的隐私和安全性。建议使用一种新颖的基于 ECDS 的加密方法来加密原始 DICOM 图像以及从 DICOM 图像中提取的 ROI 像素数据。实验计算的结果证明，通过 ECDH 进行的医学图像加密更加稳健，
