The ALIAS project addresses medical services and information inadequacy to ensure healthcare provisions in "Alpine Space" where telemedicine services are not widely exploited and linguistic barriers represent an obstacle. Alpine Space touristic vocation makes its healthcare structures "periodically" inadequate to face a widened request of services supply. On the other hand, a major receptivity of those structures during the rest of the year is unnecessary due to the low density of local residents. ALIAS is aimed at linking together a number of hospitals enabling the creation of a network shaping the ALIAS Virtual Hospital Network for sharing medical information and adopting telemedicine services to improve the efficiency of hospitals in Alpine Space areas. This article focuses on the circle of trust that has been set up among the partners of the project to address the security, authorization and identification issues of the project.
