Security threats and solutions in distributed, interoperable health information systems using middleware.

Increasingly, distributed, interoperable healthcare information systems, which meet the shared care paradigm, work across the boundaries of policy, organisational, and technological domains and are based on middleware concepts. Especially in healthcare with its sensitive personal and medical data, such systems require advanced data security measures. In the paper, a common object-oriented security model for middleware systems and advertisements for implementation are proposed, corresponding the security requirement of both the user and the application environment.

Advances in digital video for electronic media.

From media's early days of film strips and records, to today's multimedia CD-ROMs, nurses have embraced educational tools. Today, the capabilities of these tools have placed a tremendous demand for providing information any time, any where. This has led to increasing digitization of sights and sounds. Once digitized, this information can travel over information highways made up of telephone lines, fiberoptic cables, microwaves and satellites, or it can be stored on magnetic and optical media. Technological advances have made it possible for computer users to create, store and retrieve high quality digital still and moving video and audio for inclusion in electronic media. Methods for digitizing include capturing and converting the information with cameras, scanners and capture boards. Digital video compression/decompression (codec) standards vary in quality. Potential uses of digital video abound including video on demand, videoconferencing, distance learning, telemedicine, on-line education and computer-based training. Examples illustrating the differences in digital video formats will be shown during the presentation.

Privacy. Are there any guarantees?

Many health plan members worry that their medical records no longer are kept securely in paper medical files. Electronic data, they argue, is too easy to access. But healthcare administrators often need to use personal medical information to follow trends in outcomes, quality management and utilization review. Is there a balance? Kathleen O'Connor reports that Donna Shalala, secretary of the Department of Health and Human Services, recently provided some suggestions for safeguarding medical privacy in the information age.
