Toward Verifiable Phrase Search Phrase Search Over Encrypted Cloud IOT Data

Aim:

              The main aim of the project is search the encrypted data files using query phrase in the cloud server.

 Abstract:

            Phrase Search Encryption, is the important technique in cloud-based IOT system. It plays an important role in cloud based e-healthcare diagnosis system. In this case, the collected files in IOT device of Users data will store in cloud server along with the encryption. Data owner can Search the files in the cloud and decrypt the data with the set of keys. Data owner needs to register their details to upload the file in the cloud server in encrypted form. Cloud authority will give access to the Data owner to upload files. User needs to submit their details, once the cloud authority gives the access, User can search the files in the cloud server. If the search result is incorrect in cloud-based e-healthcare diagnosis will leads to endanger to the user. In order to deal with is problem, we use two-phrase strategy. In the first query, the data user can know the files containing the keywords in the query phrase, and generate the trapdoor key based on the identifiers of the next phrase. In the second query phrase, the data user can obtain the verification to check all the files containing the query phrase are correctly returned. The result proves the high security and efficiency of our proposed scheme.

 Proposed System:

          In this work, we propose the first completely verifiable search scheme the cloud-based data. In this case, it can also verify whether all files containing this query phrase are returned. Our scheme can achieve the complete verification for the search results. In order to realize the verification for search results, we design novel look-up table to verify the relationship among the keywords in the query phrase. We adopt a two phrase query strategy.
