Efficient data protection scheme in hybrid clouds

Abstract

The amount of digital data has rapidly increased at a rate of double per year since 2009. Adopting cloud computing storage services will consequently be an alternative approach to gain cost flexibility. Data encryption and access control are common data protection methods in cloud storages. However, traditional full data encryption in clouds can ensure privacy preserving but cause the low analysis efficiency problem. The emerging requirements of data analysis in clouds are balanced between data security and data analysis capacity. An efficient data protection scheme in hybrid clouds is proposed to improve data protection efficiency, rise up data availability and decrease the maintenance cost of cloud services. Data classification and selective data protection mechanisms are two key phases in this paper. According to the functional analysis and comparison results, The proposed scheme is therefore more suitable for efficiency data protection in hybrid clouds than traditional methods. © Springer-Verlag Berlin Heidelberg 2014.
