The explosion of medical image usage in clinical and research domains brings us a great challenge of securely handling, storing, retrieving and transmitting biomedical images. Medical images are often large files and they have to be stored for a long time if they are part of a patient's medical record. As medical images usually contain Protected Health Information (PHI), such data is also subjected to various regulations such as HIPAA. Cost effective measures which provide strong security for such data are essential. Therefore, we present a secure and cost effective distributed file system, JigDFS, for archiving medical images/data.
