We have developed medical information network and the ORCA network (project code "online receipt computer advantage") with VPN (virtual private network) technology. The ORCA project states to use IPv6 network to realize secure medical record backup to remote data center and collecting information for EBM (evidence-based medicine). But as the spread of IPv6 network is still in early stage, and there are many problems with security related implementation, we designed to use the IPv4 based network, but also make the migration to the IPv6 network will be with minimum cost. Our approach is widely accepted and currently over 120 clinics and hospitals are connected with our virtual private network and exchange medical information.
