PPSSER: Privacy-Preserving Based Scheduling Scheme for Emergency Response in Medical Social Networks

Mobile health monitoring, which can monitor the medical users’ real-time physiology parameters, has been expected as an effective way to improve medical service quality and make response to the emergency. Unfortunately, it also risks the information privacy of both the medical users and the healthcare service providers when they upload their information. This paper is to propose a privacy-preserving based scheduling scheme for emergency response (PPSSER) to protect the privacy of the involved users when an emergency occurs. Moreover, the multi-dimensional region query method is introduced to conseal the personal health information and homomorphic encryption is used to protect the location and attribute privacy of the users. Finally, the simulation demonstrates the effectiveness and feasibility of the proposed scheme.
