Abstract: Internet is the most common way used to share data around the globe. This sharing is backed by various cloud providers that allow customers to store & share data on the internet. But when it comes to privacy, cloud providers have consistently failed to make data 100% secure. Many data breaches, data piracy, hacking attacks have threatened the security mechanism of cloud providers. Though data stored by the customers should be 100% secure as it may contain private data which must be only accessible to the owner itself and some intended audience. So, it is very important to make this system more secure, so that data privacy & trust onto cloud providers can be maintained. We introduce a system that leverages the security of cloudbased data onto the blockchain. It allows users to store data onto the cloud and provides a prominent access control mechanism that will ensure the privacy of data. Users will be able to share data with other people in a permissioned manner by sharing the link for document with the intended user. Logs of all the operations performed with the document will be available to the owner at any instance of time. This will ensure the actual ownership & privacy of the data. Any person or third-party will not be able to access document without valid permission. This will make existing cloud storage more secure & decrease the data breaches & several attacks.
