Cloud Storage system stores the huge quantity of data in their servers. In the present system, the data owner must upload the files in the cloud server and view all the data. If data owner can modify the any data, then Third party Arbitrary (TPAR) identify the modified or missing data. If there is no change in the data stored in the cloud, then TPA will produce the verification report to the data owner. Otherwise, if TPA found that any change in the data then TPAR is called for providing the report to the owner. In case if any outer people got the permission credentials of the data owner then providing the security for the data owners files is a difficult task because the possibility for the modification of the data is very high. So, reducing this modification chance is a very important issue in these days. So, for protecting the data stored in the cloud servers here, we introduced an order preserving Encryption (OPE) scheme. In this paper, the data owner cannot view all the files uploaded by him directly. By using the keyword only, the data owner can view the files related to the searched keyword. By this, if anyone enters into data owners account, he/she unable to view the files. They can view the files only after searching the particular keywords. With this proposed system, we maintain security for the owner's data.
