Privacy Preserving on Searchable Encrypted Data in Cloud

Abstract

Cloud computing is the latest paradigm which offers different cloud services by rearranging of resources and provides them on the bases of user’s demand. Users are using cheaper data storage and computation offered in the cloud environment, and they are also facing many problems about reliability, privacy-preserving, and optimized searching of their outsourced data. Proposed scheme “Privacy-preserving keyword search” allows users to encrypt their stored data while preserving some search capabilities and also seek few efforts to consider the reliability of the searchable encrypted data outsourced to the clouds. Client-side encryption and server-side searching of encrypted data without decryption in server-side enable more efficient and eliminate privacy issues between client and server.
