A way to make public spending on healthcare more efficient is to ensure that the money is spent on legitimate causes. This paper presents the work of the iWebCare project where a flexible, on-line, fraud detection, web services platform was designed and developed. It aims to help those in the Healthcare business, minimize the loss of funds to fraud. The Platform is able to detect erroneous or suspicious records in submitted health care data sets, ensuring homogeneity and consistency and promoting awareness and harmonization of fraud detection practices across health care systems in the EU. Critical objectives included, the development of an ontology of health care data associated with semantic rules, implementation and initial population of an ontology and rules repository, development of a fraud detection engine and implementation of a data mining module. The potential impact of this work can be substantial. More money on healthcare mean better healthcare. Living conditions and the trust of citizens in public healthcare will be improved.

In this paper, we present a novel authoring tool which has been designed and developed for facilitating study design. Its underlying models are based on a thorough analysis of existing clinical trial protocols (CTPs) and eligibility criteria (EC) published in clinicaltrials.gov by domain experts. Moreover, its integration with intelligent decision support services and mechanisms linking the study design process with healthcare patient data as well as its direct access to literature designate it as a powerful tool offering great support to researchers during clinical trial design.

The platform utilizes state of the art technologies in information and communication systems, while several extension points exist so that plug-ins can easily extend the core functionality of the platform. Initial evaluation results from the system in use have provided positive feedback regarding the performance, efficiency and usability of the platform.

Furthermore, prognosis, monitoring and early detection of malignant findings can be successfully realized through synergies between physicians, researchers and general population in concert with the health policy program of each country. Information technology and computational intelligence play a crucial role in the production of digital repositories and cancer registries as well as in the development of systems to support diagnosis. In this paper we present the concept and the architecture of an approved grant under the National Strategic Reference Framework 2007-2013 (NSRF), called e-Prolipsis. Through this project, we will design and implement a web based risk estimation platform and a Central Breast Cancer Registry (CBCR) that will co-operate to provide medical doctors and patients with services such as multiplicity in diagnostic opinions, synergy, computational risk estimation, access to statistical/epidemiological data for trend estimation. Such a system, will serve as a reference tool and will help the clinician, the radiologist, the rural doctor or trainee doctor in the final assessment on the existence or likelihood of breast cancer. The system will assist in the successful diagnosis of breast cancer, giving each patient access to a large pool of doctors and at the same time, the data stored in the CBCR will be used for statistical analysis, providing useful results for improving both the cancer detection application and for making a national policy for combating breast cancer. This system will be accessible through a Web Portal, with different access levels for patients, doctors and general public and different web services available to each user group, eliminating the geographical distances that would be imposed otherwise.

The paper presents the architecture of a watermarking software development kit (SDK), which provides multiple watermarking functionality and can be customized according to the targeted medical application, in order to address security of sensitive data, origin and data authentication, image archiving and retrieval. Two use cases of the proposed watermarking SDK are presented, the one involving access to the watermarking engine through a user interface, and the other referring to the case that the engine is embedded into the image acquisition device. The nature of the embeddable information that is applicable in each use case is also described.

Yet, contemporary information access and distribution technologies raise critical issues that urgently need to be addressed, especially those related to security. The paper suggests the use of watermarking in telemedical applications in order to enhance security of the transmitted sensitive medical data, familiarizes the users with a telemedical system and a watermarking module that have already been developed, and proposes an architecture that will enable the integration of the two systems, taking into account a variety of use cases and application scenarios.

Hospital information systems (HIS) were conceived to serve that purpose. A pilot application is being developed to serve the needs of management of inpatient and outpatient medical record, the mechanism of patients' visits and bed reservation from the GPs (general practitioners) as well as the management of the drug store. Having these needs in mind we developed an intranet Web client-server application. The developed system provides a user-friendly graphical interface and features such as Internet access, access to complete electronic patient records, remote access, etc. The whole application was developed as an ActiveX Document that can be downloaded from a Web server and run from within a Web browser. The scope of this intranet based hospital information system is to improve the quality of health care provision, to minimise the institution's costs, to ameliorate time management, to increase training capabilities and to improve remote patient record access. This system will increase patient satisfaction by reducing waiting times and staff morale through high quality information systems and infrastructure
