ABSTRACT
Cloud-based Personal Health Record systems (CB-PHR) have
great potential in facilitating the management of individual health records.
Security and privacy concerns are among the main obstacles for the wide
adoption of CB- PHR systems. In this paper, we consider a multi-source CB-PHR
system in which multiple data providers such as hospitals and physicians are
authorized by individual data owners to upload their personal health data to an
untrusted public cloud. The health data are submitted in an encrypted form to
ensure data security, and each data provider also submits encrypted data
indexes to enable queries over the encrypted data. We propose a novel
Multi-Source Order-Preserving Symmetric Encryption (MOPSE) scheme whereby the
cloud can merge the encrypted data indexes from multiple data providers without
knowing the index content. MOPSE enables efficient and privacy-preserving query
processing in that a data user can submit a single data query the cloud can
process over the encrypted data from all related data providers without knowing
the query content. We also propose an enhanced scheme, MOPSE+, to more
efficiently support the data queries by hierarchical data providers. Extensive
analysis and experiments over real datasets demonstrate the efficacy and efficiency
of MOPSE and MOPSE+.

In this paper, we
explore the problem of privacy-preserving query for multi-source in the
cloud-based PHR environment. Different from prior works, our proposed MEIM
mechanism enables authenticated data owner to achieve secure, convenient, and
efficient query over multiple data providers’ data. To implement the efficient
query, we introduce MDBT as the data structure. To reduce the overhead of query
generation of data owner, and allow the cloud server to securely query, we
propose a novel multiple order-preserving symmetric encryption (MOPSE) scheme.
To make our model more practical, we propose an enhanced multiple
order-preserving symmetric encryption (MOPSE+) scheme to satisfy the hierarchical
authenticated query.
