Proposed model to decentralized storage of educational data for privacy preservation using Blockchain

Abstract

Satoshi Nakamoto created the first decentralizedblock chain in 2008. Block chain is a relatively new and widely accepted kind of decentralized, distributed computing. The advantages of block chain technology are improved security and privacy, decreased expenses, enhanced speed, and consistency. Block chain has applications in a variety of areas, including IT, healthcare, finance, and educational institutions. For data storage, many organizations now adopt centralised cloud systems. Educational Institutes stored and shared their digitally stored data with other institutes or Vendors for various purposes like issuing certificate, so protecting the privacy while sharing the data is a problem of researchers. People create a large number of files every day and wish to save them somewhere. However, they usually rely on unsecure centralized systems. Block chain is a decentralized system that keeps files and data safe. The suggested model will eliminate all cloud storage limits. It uses a block chain and an interplanetary file system to operate. It divides educational data files into blocks and then encrypts each block with hash keysOur goal is to come up with a privacy-preserving method for sharing data via block chain. A model along with Blockchain principles and features to serve the requester and data owner authentication has been developed in a two-way system
