HEALTH+Z:Confidential provider selection in collaborative healthcare P2P networks

\u3cp\u3eMany real world applications in the healthcare domain would gain a substantial advantage from sharing and search technologies available for P2P infrastructures if these technologies could provide required confidentiality guarantees. Currently, DHT-based indexes which are typically applied for effective and efficient information sharing and retrieval in P2P networks do not offer sufficient confidentiality for the patient data in a healthcare network and medical document archives. In this paper we discuss the challenges involved in securing patient data stored in a DHT-based index and discuss initial solutions to address these challenges.\u3c/p\u3
