Fault- and disaster-resistant medical cloud system for various medical applications

Because medical information is shared only in each hospital or among affiliated hospitals, it is not utilized effectively. If it can be shared between hospitals under definite conditions such as strict user authentication/authorization and anonymization, new applications such as knowledge sharing among an enormous number of medical doctors will become reality. Furthermore if the the servers or the data centers storing electronic health record (EHR) are destroyed by natural disasters or server/network failures, all EHR might be lost. The authors have been developing a medical cloud system as a fault-and disaster-resistant infrastructure for new applications. And permitted users will be able to easily provide new applications. In this paper, the authors introduce this system and a full-text search system as an example of applications using the system.
