Secure and Efficient Data Placement in Mobile Healthcare Services

摘要: Mobile health services offer access to patient data, reported by body sensors, that is stored locally on a mobile phone. Storage capacity limitations however, make storing complete copies of the data challenging and using backup cloud storage impractical as well insecure when Internet intermittent. We propose novel approach, based fragmentation caching, secure efficient management in services. Fragmentation classifies confidentiality attribute affinity. While caching prioritizes fragments frequency order compute minimum dataset information store Our simulation results demonstrate improves query response time almost 25% and, an additional 35% various workloads fragmented compared centric un-fragmented data.
