Wireless telemedicine systems: an overview

Rapid advances in information technology and telecommunications and, more specifically, wireless and mobile communications - and their convergence ("telematics") are leading to the emergence of a new type of information infrastructure that has the potential of supporting an array of advanced services for healthcare. The objective of this paper is to provide a snapshot of the applications of wireless telemedicine systems. A review of the spectrum of these applications and the potential benefits of these efforts is presented, followed by successful case studies in electronic patient record, emergency telemedicine, teleradiology, and home monitoring. It is anticipated that the progress carried out in these efforts and the potential benefits of emerging mobile technologies will trigger the development of more applications, thus enabling the offering of a better service to the citizen     

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.     

Economic Aspects of Multiservice Subscriber Loops in Telematics Networks

Since 1975, and in cooperation with the French Telecommunications Authority, we have been conducting field trials and feasibility studies to determine the capability of existing copper loop plant to support telematics services. This paper presents some of the economic information that has come out of our program. The economic analysis proceeds from a study of the technical options most likely to prove cost-effective in the foreseeable future. We present a method for comparing costs for telecommunications plant between subscriber premises and the central office of a multichannel, multiservice telematics network. The application of our method, to the possible technical solutions in any given case, leads to a series of conclusions Which could be valid for the coming stages of telematics network development.     

Integrating GPS receivers into consumer mobile electronics

Automotive electronics manufacturers are gearing up production lines to implement Global Positioning System (GPS) receivers in a new breed of location-information-based devices called telematics products. These GPS-enabled devices-car navigation systems and mayday systems-now debuting in the luxury vehicle market, will soon find placement in mid-sized vehicles and mini-vans as automotive manufacturers finalize plans to make telematics products more mainstream. GPS-enabled telematics products possess a combination of functions that make driving more pleasurable, safer and easier. These devices are a part of the larger plan to put mobile multimedia products in the cars of today and tomorrow. Although the technology behind the devices remains transparent to the driver, the benefits are realized dramatically. Car navigation systems, which use an electronic map database and provide vocal turn-by-turn routing instructions, ensure confidence when traveling through unfamiliar places. Mayday systems, using an on-board, on-demand communications device, provide the driver with the peace of mind common to owners of monitored home security systems. Car navigation systems and mayday systems each have their own hardware feature set on which different functionality can be built     

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.

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.     

Telecommunication in healthcare for a better coordination betweenhospitals and GP's: routine application of the“ISAR-Telematics” project

With the development of new information and communication technologies, the nature of data exchange between healthcare professionals is modified by the use of telematics tools. With the implementation of the “Reseau Sante Social” of the smart cards CPS and Sesam-Vitale, hospitals and private clinics are installing their hospital information systems, while general practitioners are computing their patient records. The environment is therefore suitable for the installation and diffusion of telematics services, allowing a better exchange of information between the physicians of a geographical sector. The RITHME intercommunication platform was developed in the ISAR-Telematics and IRISI European projects. It ensures several communication functions, such as movements of patients (in/out/inside) the hospital, management and mailing of letters and reports, specific information on prescribed treatments, or data concerning the hospital structure. This platform is tested in the town of Armentieres in the large city of Lille (North of France). It is being routinely used to accelerate and secure data exchanges between all the physicians working in this area     

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
