File Tracking and Security System Using BLE and Blockchain

In this era of data security crisis where the world around us works primarily with data, from the giant MNCs, Hospitals, Courts, to small businesses generate billions of terabytes of data every day. With this much data getting produced every day, it raises a massive problem of storing and keeping it safe. Handling this amount of data is the biggest challenge, and if a single piece of information is lost, that can cause a massive loss to the organization. For storing data, we can do it either electronically or physically. The probability of a file getting lost is more with hard copies. Still, most companies, government organizations, and others use old-traditional file management methods, making tracking the file between different sections difficult. Tracking and managing files are essential for every business, which also permits you to assess the overall business growth, which is amongst the most significant resources for future growth. The primary goal of this paper is to develop a more effective and practical approach to tracking files utilizing BLE (Bluetooth Low Energy) beacons and locator nodes for physical copies of information. It provides us with the file's real-time location and decreases the risk of essential files misplaced. And for the protection of electronic files, we propose a more reliable solution with cryptography and decentralization using blockchain.
