Abstract – Now a days the cloud computing is popular because they reduce the cost and complexity of owning operating computers, network resources. The benefits of cloud are low up-front costs, rapid return of investment, rapid deployment, customization, flexible use and solutions that can make use of new innovations. It seems that cloud hacks are current fashion in this age of access and therefore mainstream cloud services comes with a certain amount of risk. In order to protect both data user and data owner needs to look for each provider’s explanation of how can trust that user data is secure as send it to the cloud or download it. In this paper, we introduce keyword search for encrypted with both side verification using blockchain Technology. Data owner first encrypts the data before uploading to the cloud using index based on digital signature and has the rights to give the permission to the user, search over the outsourced data and check whether cloud fulfills the pre-specified condition or not.
