Cloud computing plays an important role in the computing world as it provides a cost-effective way of delivering services to customers through the internet. The Cloud Service Providers (CSPs) offer an enormous amount of storage space with low cost and eliminates the data management burden of the customers. As the operational details are not transparent, the CSPs may be untrusted. They may steal the user data, tamper the data, remove the rarely accessed data or hide the data loss by duplicating the data. In such cases, data integrity fails and needs to be addressed. The emerging fog computing paradigm extends the cloud platform to provide services for IoT applications. So the data integrity verification techniques are not only to be incorporated over the cloud but also to be extended for fog computing. This survey discusses the various data integrity checking methodologies for both cloud and fog environment.
