First, there is a hospital information system (HIS), which is a computerized management system for handling and supporting clinical operations, medical patient care activities, hospital’s business and administrative functions, etc. There are different types of information systems.

Moreover, a detection mechanism leveraging entropy-based metrics is introduced and its performance has been assessed.Ĭontemporary hospitals implement electronic medical records and large information systems (IS), integrated by computer networks and software applications. The bandwidth, undetectability and robustness of the proposed covert channels are evaluated, and potential countermeasures are suggested. To this aim, we develop several network covert channels that can be created by using a specific transport mechanism – the DICOM Message Service and Upper Layer Service. To improve the overall security of the DICOM standard, we investigate its susceptibility to network steganographic techniques. Information hiding in DICOM is currently limited to the application of digital media steganography and watermarking techniques on the media parts of DICOM files, as well as text steganographic techniques for embedding information in metadata of DICOM files. The DICOM ( Digital Imaging and COmmunication in Medicine) standard provides a framework for a diagnostically-accurate representation, processing, transfer, storage and display of medical imaging data.
