Searching on Encrypted Cloud Documentsusing Keywords

Abstract

Sensitive cloud data have to be encrypted to protect information safety measures, before outsourcing. The encryption technique makes effective data utilization service a very challenging job. Traditional searchable encryption technique allows users to securely search over encrypted data through keywords. The safety allows information searching scheme provides solution for secure ranked keyword search over encrypted obscure information. Ordered search greatly developed technique usability by enabling search result relevance ranking instead of sending undifferentiated results and further ensures the accuracy of folder recovery. The numerical determine process, i.e., importance gain, from information retrieval is explored to build a secure searchable index. One-to-many orderpreserving mapping technique is developed to properly protect those sensitive score information. The system facilitates server-side ranking without losing keyword security. The method is improved to importance gain active development. Investigate outcome verification is also provided in the system. One-to-many order-preserving mapping method is also enhanced in reversible manner. The similarity analysis technique is used to identify the query results under the cloud data storage.
