Passport, VISA and Immigration Management Using Blockchain

Currently in this digital world, passport is still a physical entity. It is carried at all places along with other travel related documents such as VISA and Immigration stamps that are also part of the passport(s). Each country maintains its own database of travel related information of the people entering and leaving the country. This paper is written with a vision of digitizing Passport, VISA and Immigration documents. Digitizing Passport and VISA helps in streamlining and simplifying Passport and VISA issuing, renewing, revoking, verification and validation process. For this process, we are proposing a solution based on distributed ledger for storing and retrieving information. Once implemented, this framework will help do-away with fake passports and VISA, unauthorized and repetitive data verification process. Blockchain-based distributed ledger implementation will solve several issues pertaining to paper-based authentication and make services more streamlined, improving efficiency and potentially lower costs at all levels.
