OP 2000 and MedSeC: Implementating a Medical Video Server Using a Data-secured DICOM Interface

We present preliminary results toward developing a video server that integrates security mechanisms and digital monoand stereoscopic video sequences (DSVS) into the DICOM standard. The use of public networks such as the Internet for transmitting patientspecific data must comply with local legislation on data security and integrity. The typical heterogeneous hardware and software infrastructure within a hospital requires a standardized data exchange format and a protocol like that provided by the DICOM standard in radiology. Unfortunately, DICOM does not yet include inherent data security concepts. The goal of the MedSec project is to evaluate the secure high-speed transfer of very large amounts of data within LAN/WAN networks linking project partners using DICOM 3.0 [2]. Key issues of the video server are intelligent and standardized access using a database, the DICOM protocol for data security demands, and video compression. For the compression of stereoscopic video sequences in particular, we exploit redundant information to significantly reduce data and to facilitate image management.
