(English Abstract)
With the adoption of cloud computing, database outsourcing has emerged as a new platform for a database management. Due to the serious privacy concerns in the cloud, database need to be encrypted before being outsourced to the cloud. Therefore, various kNN query processing techniques have been proposed over the encrypted database. However, the existing schemes are either insecure or inefficient. So, we, in this paper, propose a new secure kNN query processing algorithm on the outsourcing database environment. Our algorithm guarantees the confidentiality of both the encrypted data and a user's query record. To achieve the enhanced query processing efficiency, we also devise an encrypted index search scheme which can perform data filtering without revealing data access patterns. We show from our performance analysis that the proposed scheme outperforms the existing scheme in terms of a query processing cost while preserving data privacy.
