Security Framework for Pervasive Healthcare Architectures Utilizing MPEG-21 IPMP Components
An example view of an MPEG-21 IPMP container which contains three items—one not protected and two protected with the
use of a cryptographic tool that is remote referenced at the location urn:IPMP_Tools:ToolServer:ToolSymEnc08. Before
the user decrypts the contents, he must decrypt the license that accompanies
the content, which will provide to the user the decryption key and usage rules
of the content. The license is binded to a specific user and it is included
into the item encrypted using a public-key algorithm; in our implementation, we
used RSA , and the license has been encrypted using the users' public key.
For the creation of the aforementioned MPEG-21 IPMP-based file, we have used
the AXMEDIS editor .
