NETWORK-BASED COLLABORATION FOR SECURE DATA INTERCHANGE FOR IMAGE DATA RECORDS HAVING CONFIDENTIAL COMPONENTS

A network-based system (and method) is disclosed for the collaboration of transmission nodes and receiver nodes for secure data interchange for radiological image data records including confidential components. The processing node provides a set of virtual clients, wherein a virtual client is associated with a respective receiver node and is intended to provide the intended pseudonymized image data record. A connection message is sent to the respective receiver nodes. The connection message includes a reference to the address of the virtual client that the receiver node can use to retrieve the pseudonymized image data record if it is situated outside a security domain of the transmission node. Furthermore, the connection message includes a reference to a memory address in the local PHI share memory unit that the receiver node can use to provide the original image data record if the receiver node is situated inside the security domain.
