A Trust Management Scheme for Sharing Secure Medical Images over Cloud Computing Environment

Abstract—Recently, sharing patients' history all over the world becomes a necessity to facilitate the storing, transforming and consequently the further diagnosing processes. As for medical images, there are special requirements needed such as the quality that should kept high while preserving the security and privacy arrangements especially when dealing with a public sharing environments such as the cloud computing. Therefore, performing limited sharing through the trust management will help to achieve the security needs. This paper introduce an efficient watermarking technique to guarantee the secure DICOM images sharing over the cloud computing environment using two levels of authentication through private secret key, dynamic embedding/extraction and Cloud watermarking algorithms. The experimental results are promising and showing that the proposed technique gives high PSNR for the watermarked images and their ROI respectively. It also shows robustness against the transition attacking attempts and preserves the DICOM format of the medical images.

Index Terms—Cloud computing, ROI, cloud drops, dynamic embedding, spatial synchronization, watermarking.
