CEDIMS: cloud ethical DICOM image Mojette storage

Dicom images of patients will necessarily been stored in Clouds. However, ethical constraints must apply. In this paper, a method which provides the two following conditions is presented: 1) the medical information is not readable by the cloud owner since it is distributed along several clouds 2) the medical information can be retrieved from any sufficient subset of clouds In order to obtain this result in a real time processing, the Mojette transform is used. This paper reviews the interesting features of the Mojette transform in terms of information theory. Since only portions of the original Dicom files are stored into each cloud, their contents are not reachable. For instance, we use 4 different public clouds to save 4 different projections of each file, with the additional condition that any 3 over 4 projections are enough to reconstruct the original file. Thus, even if a cloud is unavailable when the user wants to load a Dicom file, the other 3 are giving enough information for real time reconstruction. The paper presents an implementation on 3 actual clouds. For ethical reasons, we use a Dicom image spreaded over 3 public clouds to show the obtained confidentiality and possible real time recovery.

Réflexion éthique sur la pluridisciplinarité et la confidentialité de l’information en imagerie médicale via les nouvelles technologies de l’information et la communication

Technological advances in medical imaging has resulted in the exponential increase of the number of images per examination, caused the irreversible decline of the silver film and imposed digital imaging. This digitization is a concept whose levels of development are multiple, reflecting the complexity of this process of technological change. Under these conditions, the use of medical information via new information and communication technologies is at the crossroads of several scientific approaches and several disciplines (medicine, ethics, law, economics, psychology, etc.) surrounding the information systems in health, doctor-patient relationship and concepts that are associated. Each day, these new information and communication technologies open up new horizons and the space of possibilities, spectacularly developing access to information and knowledge. In this perspective of digital technology emergence impacting the multidisciplinary use of health information systems, the ethical questions are numerous, especially on the preservation of privacy, confidentiality and security of medical data, and their accessibility and integrity.

Une société consumériste d'information orientée vers une infosphère éthique / For an Ethical Infosphere in our Consumer-Oriented Information Society

Aujourd’hui, l’émergence des technologies de l’information et de la communication illustrée par les médias et le développement d’Internet s’imposent à nous. On assiste à une société consumériste d’information où les biens d’information se développent au détriment des liens sociaux. Dans ce contexte, nous sommes amenés à nous poser des questions sur la mutation de la société vis-à-vis de l’information notamment dans le domaine médical. Une société de communication centrée sur des valeurs humaines et éthiques telles que le partage et l’échange ne devrait-elle pas remplacer notre société orientée vers la consommation de l’information à tout prix ?
