Figure 8

A schematic view of the encapsulated medical data into an MPEG-21 container. The first item is not protected, and it contains some data which can be used by the IT personnel in order to store the protected file into appropriate databases. The second item is protected, and it contains some part of personal data for the patient. Finally, the last item is also protected and includes the detailed medical data measurements. Each item is encrypted using different encryption keys, so each item can be seen only by users that possess the appropriate key for decryption.
