Abstract

A query from peer node in a cloud is an antique in a spatial database. The application of this is more in geo location based services, clustering, classification etc .For confidentiality and data security, the data is stored in cloud is encrypted form. In before review it is assumed that the query users(QU) knows the encryption and decryption key. But it is actual practice, it is false. Many users are neither trusted nor knowing the key. A new approach that K-NN query algorithm is proposed in which Data Owner and Query user will hold the encryption key. All the query users will have different keys never share each other. The data uploaded by data owner is divided into different parts. These parts are stored in a multiple data clouds after encryption key. All the query user will have the different keys never share each other. The data uploaded by Data owner is divided in to different parts. These parts are stored in a multiple data clouds after encryption, hence effectively by handling the load on the network decreasing latency of query.
