A Survey on Encrypted Data Retrieval in Cloud Computing

With the advent of cloud computing, data owners are motivated to outsource their complex data management systems from local sites to the commercial public cloud for great flexibility and economic savings. Every owner data is encrypted before stored in the cloud server. Considering the large number of data users and documents in the cloud, it is necessary to allow multiple keywords in the search request and return documents in the order of their relevance to these keywords. We use ranked search scheme (co-ordinate matching algorithm) to find the similar data or information stored in the cloud and also it is used to retrieve the encrypted data. We use many technologies and binary data generation is the process which is used to create index value for the data and store it in the cloud. Data ciphering is the process of creating the cipher text for the owner data which is data owner wants to store in the cloud. Data user access control technique which provides access right to the data user before getting the full detail of the data user. Data user is enabled to create queries to retrieve data by the Data user query. The index value is attached to every data and it is stored in the cloud. If the user wants to retrieve the data from cloud then the given index value is to be matched with the index value in the service provider.
