Encryption of Medical Images using Steganography for Mobile-cloud- A Survey
Main Article Content
Abstract
The resource constrained devices are used for outsourcing the medical images to cloud for selective encryption by using steganography. The visual saliency model is used to detect region of interest from medical images. In the host image the important detected data is embedded. Stego image is produced for encryp-tion by outsourcing to cloud. The image is encrypted by powerful resources of cloud and then sent to client. The selected encrypted region of interest is extracted by client and combined it with non region of interest and then the selectively encrypted image is formed and can be sent to health care centers and medical spe-cialists. The image quality, security and computational complexity are analyzed validate effectiveness. The applicability of moni-toring centers in remote patient is verified.
