Securing Cloud Based Data Storage Using Blockchains

Abstract

The most common way of sharing data around the world today is through the Internet. This sharing is supported by different cloud providers which enable customers to store and share data online. However, cloud providers have consistently failed to ensure that data is 100 percent secure when it comes to privacy. Many data breaches, data piracy and cyber-attacks have put the security mechanisms of cloud providers at risk. Although data stored by customers should be 100 per cent secure, it may contain personal data that must be accessible only to the owner and certain targeted audiences. It is therefore very important to make the system more secure in order to maintain the privacy and confidence of the data providers in the cloud. With this document, we are introducing a system that puts cloud data security on a blockchain.
