Tampering Detection of Distributed Databases using Blockchain Technology

Abstract

Data stored in different kinds of Database management systems is always prone to tampering through internal or external sources. To detect such malicious changes in the database we use various Database Tampering Detection methods. A major find in this area was to use one-way cryptographic hash functions as well as use of digital watermarking to detect any tamper in the data. But these techniques won't work on Distributed Database. In this paper, we have put forth the idea of using a Distributed Database to store data and we can easily detect any malicious transaction using Blockchain technology in it. It is simply a digital ledger bound using cryptographic principles.
