A Novel Privacy- Preserving K-NN Classification Protocol Over Encrypted Data

A B S T R A C T Data mining is used for various ways like government sectors, private sectors eg. Banking, Research center. Data mining is the classification process. Now a days, due to the growth of Internet various privacy issues arise. In classification problem different security model will be prepared. Now a days, due to the growth of cloud computing, user can outsource their data on cloud in encrypted form and can apply data mining tasks on cloud. In data mining privacypreserving classification technique are not applicable. So, in our paper we are solving the privacypreserving classification problem over encrypted data. We are using k-NN classifier technique over encrypted data in cloud. The proposed system provides-Confidentiality of data, Privacy of user input query, Hides data access patterns
