In the case of telemedicine systems a patient's medical profile and other medical information is transferred over the network from the examination lab to the doctor's office in order for the doctor to be able to perform a diagnosis. The medical information transferred across the network should be encrypted, secured and protected until it reaches its final destination. Patients' medical profiles should be accessible by their doctors in order to support diagnosis and care, but must also be protected from other patients, medical companies and others who are not certified by the patient to access his medical data. A very important element of virtual communities is trust. Trust should be built upon the same specifications for secure data transfer and leveled access with medical information. Furthermore, trust requires a strict policy based mechanism, which defines roles, access rights and limitation among community members, as well as a flexible identification mechanism, which allows anonymity of patients, while in the same time guarantees the truthfulness of doctors' identity and expertise.

A critical requirement for the success of a web application for healthcare is to be trusted from all participants. In order to build trust, the application should guarantee security, confidentiality, and reliability for people, data and processes. The medical profile of patients must be protected from unauthorized access and the medical advice should come from experts only. Information exchanged between any two parties should be transferred securely, should be preserved for future use and processed in accordance to predefined procedures that take into account all ethical and legal restrictions. All the above state the need for a strict policy-based mechanism, which defines roles, access rights and limitations on information access and a flexible identification mechanism, which allows anonymity of patients, and guarantees the truthfulness of doctors' identity and expertise. This work presents a holistic approach on certification and security in health related web-applications with emphasis on standards, protocols and procedures.

In our hypothesis, the Hospital IS has been in operation for a period of time and the Hospital managers have to choose between the replacement with a new Information System (IS) and the continuation of its use. Leaving aside the economic factors concerning the return of a possible investment, the decision is still difficult and will be based on scientific and technological factors. The proposed methodology employs confidential information from the Hospital, which relates to the system operation and usability, the satisfaction of doctors and patients etc. It also examines the entire working environment and common factors that affect the choice of Hospital managers (e.g. financial constraints).

Several frameworks have been proposed in order to capture various dimensions of social media and measure their impact in people's social, professional and other activities. The effect of social media and Web 2.0 applications in the healthcare sector is also significant. This paper examines Greek healthcare professionals' attitudes towards Internet social media and mobile technologies, explores their familiarity with social networks and associates their answers with their professional profile. Results are discussed within the context of the growing international relevant literature.

Patient monitoring and medical consultation and support are the most popular activities inside health care communities. They bring together medical experts and patients and require confidentiality, reliability and trust in order to be successful.
