Cloud computing has been considered as a new model of enterprise IT infrastructure, which can organize huge resource of computing, storage and applications. It enables the users to access the network to a shared pool of configurable computing resources with great efficiency and minimal economic overhead. In the era of big data, huge amount of data produced world-wide is stored on the cloud. Despite the various advantages of cloud services, outsourcing sensitive information to remote servers brings privacy concerns. The cloud service providers who store user’s data may access sensitive information without authorization. A general approach to protect the data confidentiality is to encrypt the data before outsourcing. In this study, we address the problem of privacy preserving using multiple keywords search over encrypted cloud data. Our approach provides multi-keyword search based on coordinate matching.
