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).
医学图像是医疗保健信息系统不可或缺的一部分。由于图像信息的关键性以及医疗环境中严格的隐私要求，医学图像数据库系统必须提供合理的安全保障，以确保图像的保密性、完整性和可用性，从而使其能够得以部署。在本文中，我们主要探讨保密性问题。例如，只有授权用户才能访问医学图像。对图像的访问通常基于某些安全约束条件。安全约束处理是传统（非多媒体）数据库系统中用于获得所需适当安全级别的一种广泛使用的机制。然而，多媒体环境中的安全约束处理存在一些有趣的问题。在本文中，我们阐述了在医学图像数据库上使用基于内容的安全约束的优点和问题。我们还提出了一种将安全约束集成到医学图像数据库中的方法，同时考虑到医学图像的真正多媒体特性（例如医学图像的内容）。
