A Framework for Identity Management System Using Blockchain Technology

Abstract

Identification is important for a person and country. Identity contains valuable information. It contains fingerprints, Name, Date of Birth etc. By using this we can identify someone. So, it is very important to secure this data. Nowadays we are using a server to store the database. But somehow the unethical people managed to modify this data. And there they managed to get unauthorized access. This is a threat for a country. By using this they can easily get passports and other facilities. That’s why the security of a person's identity is very important. Blockchain technology facilitates greater assurance in the data being shared across a network, providing enhanced security, improved transparency, and allowing for easier tracking of the information. If we use this technology in our identity system, this will increase trust. And the system will be secure enough. To ensure security of the identity system is our main purpose of our research-based project. In our system we use Ethereum smart contact. We performed comprehensive testing in a variety of scenarios and conditions with a wide range of users using Remix IDE. Using Remix IDE, we can simulate a realistic situation that has an owner and multiple users by having access to multiple Ethereum wallets. Some security properties are anonymity, integrity, privacy, security, authenticity, trust, immutability, decentralization. Our system can ensure all those security properties. There are some security properties such as immutability which are ensured by our proposed system.
