This paper presents a fog computing approach to overcome the security issues with the semi-trusted cloud service provider. The existing cloud solution is quite weak that can easily be cracked. As most clients stores sensitive data on the cloud, data security is a major concern that needs to be addressed. The proposed system can able to keep the data integrity of the stored data on the cloud for the data owner. By dividing the data into blocks and store some part of the data on the fog node and store the remaining data on the cloud in double encrypted form so the semi-trusted member cannot access the original data. It maintains the privacy of the stored data due to double encryption of the data and also the file is stored in two different locations so if CSP tries to access the file then he cannot get the whole data.
