ABSTRACT:
Sharing digital medical records on
public cloud storage via mobile devices facilitates patients (doctors) to get
(offer) medical treatment of high quality and efficiency. However, challenges
such as data privacy protection, flexible data sharing, efficient authority
delegation, computation efficiency optimization, are remaining toward achieving
practical fine-grained access control in the Electronic Medical Record (EMR)
system. In this work, we propose an innovative access control model and a
fine-grained data sharing mechanism for EMR, which simultaneously achieves the
above-mentioned features and is suitable for resource-constrained mobile
devices. In the model, complex computation is outsourced to public cloud
servers, leaving almost no complex computation for the private key generator
(PKG), sender and receiver. Additionally, the communication cost of the PKG and
users is optimized. Moreover, we develop an extensible library called libabe
that is compatible with Android devices, and the access control mechanism is
actually deployed on realistic environment, including public cloud servers, a
laptop and an inexpensive mobile phone with constrained resources. The
experimental results indicate that the mechanism is efficient, practical and
economical.
