An embodiment of the present invention includes a system and method for detecting and monitoring confidential and DICOM image traffic on a computing device in a PACS network. Embodiments of the present invention protect patient confidentiality by preventing the simultaneous display of confidential images and patient identification information when measuring and displaying the image data. The system detects and measures the transfer of confidential images and stores and displays information included in only the non-confidential headers of the images. The system monitors and warns (such as via email and/or pagers) PACS administrators of system slowdowns as a result of the data gathered.
