Research and Implementation of Cipher-text Data Retrieval Method Based on Cloud Storage
-
Abstract
To solve the problem of mass data encryption retrieval in the development of cloud storage service,a new cipher-text data retrieval method is proposed.In this method,a new retrieval method is designed which use inverted index as the index structure.Firstly,user inputs the query words and matches on the cipher-text index precisely and transfer the word into other forms and correct the wrong word to query again.And then repeat the above steps under the circumstance if the returned result is lower than the pre-set threshold.This cipher-text data retrieval method improves the privacy of stored data to make users obtain the results what they expect.Finally,experimental results show that the scheme is effective.
