User authentication to access secure data

Pavel Navratil, Karel Slavicek, Otto Dostal

Since January 2002 Institute of Computer Science in Masaryk University operates regional archive of medicine image information. All connected clinet appliences utilize DICOM standard with pure user authentication capabilities. For Authentication putposes mostly IP address of applience is used. This solution is satisfactory for modalities but not suitable for distant consultants and mobile users. This weakness of DICOM standard we have bypassed by utilization of IPSEC tunnels and assigninng client address based on user authentication.
