Security of medical image databases.
Medical images are an integral and indispensable part of health care information systems. Because of the critical nature of image information and stringent privacy requirements in medical environments, the medical images database systems must provide reasonable safeguards to assure confidentiality, integrity and availability of images to be deployable. In this paper we address mainly the confidentiality issues. Only authorized users should have for example access to medical images. Access to images is usually based on certain security constraints. Security constraints processing is a widely used mechanism for obtaining the appropriate level of the security required in traditional (non-multimedia) database systems. However, the security constraints processing in multimedia environments possess a number of interesting problems. In this paper we address the advantages and problems of using content-based security constraints on medical image databases. We also propose a methodology for the integration of security constraints into medical image databases, taking into account the true multimedia nature of the medical images (e.g. the content of the medical images).
