Cloud computing is said to be centralized as all the data is stored over cloud. Data maybe or may not be sensitive but then to compromise over privacy is not acceptable. Data must be encrypted before outsourcing. Due to encryption, utilization of data becomes difficult, then also traditional software is capable to retrieve the data even when encryption is performed but for to get data exact keyword must be matched while search in order to download the required file else the user will get empty data. That is no tolerance of even minor typo error and this type of error were found frequently.
