Abstract

In digitizing era, we can digitize the medical images and store it on cloud and retrieve from cloud. Medical images are digitized in the standard form called DICOM (Digital imaging and communications in medical standard) format.
When we are outsourcing these medical images which contains sensitive information about patient like medical status about the patient we need to give privacy for this information. If a hacker wants to identify sex of a fetal, he can easily identify the particular fetal image from the set of images because the
patients information in embedded inside the image.
This paper proposes a novel framework to enhance the protection of DICOM images and privacy of personal data. In the proposed system metadata and image is extracted from DICOM image and encrypted separately using user defined key. The metadata is encrypted using modified AES algorithm and this encrypted data is again encrypted to enhance the security. When a doctor from
remote location wants to access a medical image for diagnosis purpose, he can access the encrypted metadata and corresponding encrypted medical image from the database in cloud and decrypt it. A user specific key is needed for decrypting them. Owner will pass the user-specific key to the requested user if
he is a authorised user.
