Every day billions and trillions of data are generated from different sources. To store such a huge amount of data need large storage, for that cloud becomes the most effective solution due to the properties like flexibility, cost-effectiveness, and scalability. It has become a suitable and efficient option for the storage of data. But with the storage of data on a cloud platform, it is very essential to avail all possible securities to the data stored in the cloud. That aim can be achieved by providing access control to the data and storage. Storage can be made secure by implementing user-level access methods. User-level Access Control prohibits the storage at the user level itself. All the users do not have the same permissions in storage access. Some users are allowed to only read as well as write data/files in the storage, some are allowed to only read data and write data in the storage. All this access control is achieved by writing certain rules concerning the storage of the cloud platform.
