Enforcing Privacy in Cloud Databases
This work addresses privacy issues for users of Database-as-a-Service in cloud computing, but it is incremental as it is a survey paper.
The paper surveys mechanisms for securing databases in cloud environments to address privacy concerns, highlighting current pitfalls and research challenges without presenting new experimental results.
Outsourcing databases, i.e., resorting to Database-as-a-Service (DBaaS), is nowadays a popular choice due to the elasticity, availability, scalability and pay-as-you-go features of cloud computing. However, most data are sensitive to some extent, and data privacy remains one of the top concerns to DBaaS users, for obvious legal and competitive reasons.In this paper, we survey the mechanisms that aim at making databases secure in a cloud environment, and discuss current pitfalls and related research challenges.
