A Practical National Digital ID Framework on Blockchain (NIDBC)

Abstract

Currently, government identification systems are still underdeveloped. The government has adopted computer technology to serve the policy of Thailand 4.0. Thai national ID still segmented and distributed between government agencies and has no centralization, and it brings bad experience to the users because each service must be registered and the users have to remember the username and password for every service. We demonstrated Thailand national Digital ID Framework based on Blockchain (NIDBC) to help improve digital identity government service to simple single sign-on and kept preserving privacy by providing personal information to service only when users grant permission for each service. In addition, the system is secure because the data is distributed to each node, making the attackers hard to attack or edit information. The security properties of the proposed protocol have been verified using Scyther tool and are presented here with results.
