Context-aware assistive environments face difficulties due to the limitations of the current Internet design. Such systems demand complex information manipulation and effective security mechanisms which currently have to be provided with add-on solutions. This is necessary as users utilize various devices for creating and retrieving information as well as because the generated content contains sensitive data which has to be properly secured. The authors showed that by designing an architecture around information items and by providing functions for manipulating and securing them, pervasive health assistive solutions can be easier deployed.
