Design and development of an interactive medical teleconsultationsystem over the World Wide Web

The objective of the medical teleconsultation system presented in this paper is to demonstrate the use of the World Wide Web (WWW) for telemedicine and interactive medical information exchange. The system, which is developed based on Java, could provide several basic Java tools to fulfill the requirements of medical applications, including a file manager, data tool, bulletin board, and digital audio tool. The digital audio tool uses point-to-point structure to enable two physicians to communicate directly through voice. The others use multipoint structure. The file manager manages the medical images stored in the WWW information server, which come from a hospital database. The data tool supports cooperative operations on the medical data between the participating physicians. The bulletin board enables the users to discuss special cases by writing text on the board, send their personal or group diagnostic reports on the cases, and reorganize the reports and store them in its report file for later use. The system provides a hardware-independent platform for physicians to interact with one another as well as to access medical information over the WWW     

A framework for discovering relevant patterns using aggregation and intelligent data mining agents in telematics systems

The emerging technology in vehicle telematics drives several stakeholders in this field to consider services that could be beneficial for both clients and the telematics service providers. In particular this paper proposes a novel framework for insurance telematics in Korea using a mobile aggregation agent (AA) and intelligent data mining agent (IDMA). To our knowledge, this model is recent of its kind in this country and the base-line information from driver’s characteristics serves as reference for the flexible insurance policies. We are able to present a use-case scenario and illustrative examples to demonstrate our model. With this flexible insurance framework, customers can manage their own insurance premiums and lower the cost of motoring. Promising applications of this system to business and industries have been recognized and discussed.     

Intelligent image management in a distributed PACS and telemedicineenvironment

Advances in information technology in the past decade have resulted in a proliferation of clinical information systems dedicated to individual user groups and clinical functional areas. This, in turn, has led to the need for hospital-wide management and integration of information, and has triggered major efforts towards the development of integrated hospital information systems. A framework for developing an integrated regional health telematics system is presented, based on the functional and data integration of federated autonomous information systems. The concept of the patient meta-record is introduced as a central element in achieving integration in terms of content, structure, and access to information resources. Intelligent image management at the level of either a single health care provider (hospital) or a regional health telematics network is addressed and is achieved through event and model-driven strategies enabled by a distributed hierarchical storage management system. Intelligence, in this context, refers to methods of efficient and effective real-time resource management in the timely delivery of health care     

Integration of clinical information across patient records: acomparison of mechanisms used to enforce semantic coherence

Semantic coherence of clinical information is the bottleneck for true interoperability among applications in health telematics. Healthcare records are in principle made up of statements about the patient's health and activities performed, organized within attested transactions or messages. Various mechanisms have been developed to optimally represent details of statements in a record system, creating de facto three subdivisions: (1) “containers” of clinical information, i.e., section headings, data elements in local records; segments and data fields in messages; (2) their “contents,” i.e., coding systems and terminologies; and (3) “transaction context,” i.e., circumstances related to document production and message exchange, typically represented in their headers. Details rely on a common semantic background and should, therefore, be seen in a continuum; nevertheless, design methodologies and tools for the three subdivisions evolved independently and assignment of details to subdivisions is not predetermined by principles, but depends on implementation issues. Recent developments within the European Committee for Standardization (CEN/TC251/WG II) and in the European Project GALEN-IN-USE provide a new insight on semantics in healthcare. In order to guide harmonization of semantic aspects in the different series of standards-in information models, messages, document markup, terminology systems-we present a comparison of the various mechanisms they use to enforce semantic coherence on clinical information

Data Protection and Data Sharing in Telematics

Automotive telematics may be defined as the information-intensive applications enabled for vehicles by a combination of telecommunications and computing technology. Telematics by its nature requires the capture, storage, and exchange of sensor data to obtain remote services. Such data likely include personal, sensitive information, which require proper handling to protect the driver's privacy. Some existing approaches focus on protecting privacy through anonymous interactions or by stopping information flow altogether. We complement these by concentrating instead on giving different stakeholders control over data sharing and use. In this paper, we identify several data protection challenges specifically related to the automotive telematics domain, and propose a general data protection framework to address some of those challenges. The framework enables data aggregation before data is released to service providers, which minimizes the disclosure of privacy sensitive information. We have implemented the core component, the privacy engine, to help users manage their privacy policies and to authorize data requests based on policy matching. The policy manager provides a flexible privacy policy model that allows data subjects to express rich constraint-based policies, including event-based, and spatio-temporal constraints. Thus, the policy engine can decide on a large number of requests without user assistance and causes no interruptions while driving. A performance study indicates that the overhead is stable with an increasing number of data subjects.

A smartphone‐centric platform for remote health monitoring of heart failure

Heart failure is a chronic disease that alternates intense and weak phases and requires repeated and frequent hospital treatments. The use of automatic instruments for a remote and ubiquitous monitoring of biological parameters relevant to heart failure pathophysiology offers new perspectives to improve the patients' quality of life and the efficacy of the treatment. The platform described in this paper represents an implementation of an automatic remote monitoring tool where smartphones play a crucial role. They are not employed just to communicate through traditional client‐server applications and they are not only the hub of information sent by sensors, but they also act as intelligent processors and autonomous sensors of the patients' motion through a high‐accuracy activity recognition algorithm. The proposed platform combines the evolution of health systems and the consequent needs of modern telemedicine with the current context‐aware capability of recent smartphones, obtained by implementing specific algorithmic solutions, and with the anything, anytime, and anywhere communication capability of the pervasive communications paradigm. Performance evaluation focuses on the accuracy of the activity recognition estimation, on its applicability to real life, and on the data exchange between smartphones and medical server, allowing to envisage the potential of the designed platform.

Consumer Vehicle Telematics — An Emerging Market Where Web Services

This paper examines how Web Services can be used to provide a shared infrastructure in an emerging area of consumer communications, namely consumer vehicle telematics. The paper reviews the key advantages which Web Services offer from a service provider's viewpoint — namely openness, reuse and ease of integration with legacy systems. The paper then goes on to examine why the consumer vehicle telematics industry is an area where point solutions have been developed. It then explores why legislation, changes in industry dynamics and the growing use of electronics in vehicles make the use of Web Services, in the software platform supporting the applications, an attractive proposition. Using a scenario-driven approach, it is shown how Web Services can be employed to provide reusable components which can make applications available for vehicle manufacturers, vehicle dealers, legislators and third-party service providers. These applications can be used to provide information to drivers, occupants and vehicles themselves. The paper also presents a brief review of the emerging competitive environment. This revised version was published online in July 2006 with corrections to the Cover Date.

Federation solutions for inter- and intradomain security in next-generation mobile service platforms

A federation approach for security in future distributed service delivery platforms for mobile users offers some key advantages over an integrated solution relying on a common choice of a standardized authentication technology. By agreeing on an exchange protocol for security assertions rather than on the detailed security mechanisms, Service Aggregators and Access Network Operators will be able to federate their customer offerings flexibly and jointly offer services. The consumer will find formerly separate offerings combined, and Service Operators will enjoy open interfaces towards the network's service delivery platform. Through the use of Security Assertion Markup Language (SAML), standardized assertion statements can be made not only for the user's identity, but also on attributes and authorizations associated with it. This will allow a seamless personalized service experience offering single sign-on across separate operational domains. An example from automobile telematics is used to illustrate the concepts.
