Abstract:
Cloud computing provides several applications and resources to users in pay-as-yougo
manner and saves huge capital investment. Many methods have been investigated
to withstand attackers like data anonymization, Privacy-preserving architecture,
dynamic metadata reconstruction. For the research work, the Personal Health Records
are collected and sources are given to the researchers. In proposed technique, the
research focuses on privacy preservation using Dynamic Metadata Reconstruction for
shared PHR. EKMC Clustering algorithm is used to cluster the data. Next step is table
splitting in which normalization is done. For that X.509 certificate is used. Ephemeral
referential consonance is used to preserve privacy of user exclusive private data. Data
Aggregation and Deduplication (DAD) algorithm decrease the cost of storage by
removing repeated data in cloud.
