Todays cloud storage is completely dependent exclusively on large storage providers. These storage providers act as un trusted third parties, which transacts the data for storing, sending and receiving the data from an organization.Thistypeofmodelpossessesanumberofissueslike high operational cost, data availability and datasecurity. Inthispaper,weintroduceaprototypeofmulti-usersystemfor access control to datasets that uses blockchain technology to provide a secured distributed data storage. The system allows the data owner to upload the data through a Web Portal. So, the user who has the secret key of particular data which was uploaded on Cloud in the encrypted form can only access the file. Finally, the system supports the privacy of data by ensuringtheimmutabilitypropertyoftheblockchainbystoring them on cloud.
