Blockchain based Digital Identity Management System: A Case Study of Myanmar

Although Blockchain technology is formerly invented for digital currencies such as Bitcoin, its applications have extended into such areas as fair voting, healthcare, banking, and digital identity. A blockchain `s data is cryptographically connected and distributed across multiple computers, making them nearly impossible to temper with. Hence, this paper considers the possible use of introducing blockchain technology for digital identity management system for the issue of digital identity (passport) in Myanmar. Through blockchain technology, all the passport offices in Myanmar will be connected to each other in decentralized environment and enough passport information of a person can be securely shared within peers. Therefore, the proposed system can hinder the illegal duplication of passports (different types) since a valid passport can be issued only once to a person (except passport loss, renewal and expired) and it is impossible for a person to apply more than one passport type in the decentralized system. In addition, in the proposed system, the authenticity of passport can also be verified after granting permission for international travel. Therefore, the proposed system can be effectively applied for the passport offices in Myanmar for verifying the passport application and its data authentication.
