With the increasing popularity of location-based services and the excessive use of smart phones and GPS enabled devices, the practice of outsourcing spatial data to third party service providers has grown rapidly over the past few years. Meanwhile, the fast arising trend of cloud storage and cloud computing services has provided a flexible and cost-effective platform for hosting data from businesses and individuals, further enabling many location-based applications. However, in this database outsourcing paradigm, the authentication of the query results at the client remains a challenging problem. This paper presents a novel method for authentication of query results based on the ideas of Authentication Data Structures. The idea of Merkle Hash Tree is adopted which allows a client to verify the correctness and completeness of the result set. A novel authentication scheme is suggested based on the concepts of Merkle Hash Tree and quadtree for verifying the authenticity of outsourced spatial databases.
