Towards a Decentralized OSN for a Privacy-preserving e-health System

Yahya Benkaouz, Mohammed Erradi
2015 Procedia Computer Science  
Due to the sensitivity of health data exchanged over such networks, a special attention need to be paid to security and privacy aspects of these data.  ...  In this work, we suggest a layered architecture while promoting the usage of decentralized design to ensure the scalability and the privacy of an OSN-based e-health system.  ...  Thus, we promote the usage of fully decentralized or hybrid architecture to ensure the scalability and the privacy of the e-health system.  ...
