Proceeding of the 1 st International Workshop on Privacy-Preserving IR : When Information Retrieval Meets Privacy and Security ( PIR 2014 ). Abstract: Many 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.
