MMany attempts have been made over the last two decades to computerize the management of patient records using advanced computing and networking facilities across hospitals, clinics, and
billing agents. A patient’s record represents the key repository for information concerning his or her health care. While patient record management has achieved modest progress within a closed organization in terms of facilitating seamless integration with an organization-wide health information system, its provision for open patient record management has met with little success. A truly ubiquitous availability of patient records can greatly improve health care delivery by providing medical personnel with timely access of often critical medical records such as past medical history, blood type,
and even next-of-kin information [3, 11]. With the increasing mobility of individuals in a global economy, the demand for providing anytime, anywhere, anyplace access to a patient’s medical record has not been met [6].
JCWS Architecture Overview
The main objective of the JCWS architecture is to form a Web service interface between the smart card data objects repository and a standard Web browser. The framework is comprised of two sublayers of Java-based components, as depicted in Figure 4. The Web Servlet Component (WSC) layer is concerned with providing general Web services to incoming requests. It functions specifically as a lightweight
HTTP Web server to the smart card’s Web repository.
Conclusion
As VLSI technology continues to advance, processor- based smart cards will be packed with more powerful processors, with much higher memory configuration, capable of storing tens of pages of text. Such advancement offers the possibility of moving away from the use of pure optical memory cards (currently used in most Hong Kong medical
smart card trials [12]) to a more general processorbased smart card for medical applications. This will enable us to use the processing capabilities of the built-in processor, while incorporating the rich benefits of Java Card technology. More importantly, this will significantly reduce the per-unit cost of a smart card and the associated card reader.
