In the modern health service, more and more users outsource data to cloud storage servers, where only the authorized users can access it. However, this data is prone to be exposed to many attacks, in particular by the cloud provider’s personnel with privileged access. In this paper, we focus on the medical images. To protect user’s privacy and avoid illegal access to the comprehensive content of these images, we propose a framework using the content-based fragile watermarking and encryption techniques. The image’s digital signature and the encrypted data of the patient are embedded into the image, which will be stored in the cloud.

Keywords: Medical data, watermarking, AES, LSB, cloud computing.
