SPOC: A Secure and Privacy-Preserving Opportunistic Computing Framework for Mobile-Healthcare Emergency

Abstract:

In mHealthcare system, patient’s PHI is always considered being reported to the eHealth center through smart phones, and the primary security issue is to keep the patient’s PHI secret, and only the related medical professionals at eHealth center can read them. However, due to patient’s smart phone mobility, patients can often contact with each other in mHealthcare system. We introduce an efficient user-centric privacy access control in SPOC framework, which is based on an attribute-based access control and a new privacy-preserving scalar product computation (PPSPC) technique, and allows a medical user to decide who can participate in the opportunistic computing to assist in processing his overwhelming PHI data. We call such kind of social contact as mHealthcare social network (MHSN).
