Secured implementation of Passport portal using Blockchain
A passport is an official document issued by a government, certifying the holder's identity and citizenship and entitling them to travel under its protection to foreign countries. This service requires to be of utmost importance on a global scale inorder to ensure basic safety for the immigrants in any country. With the introduction of online Passport application services, the system has become far more effective than the primitive procedure. But, on the other hand, it is now more vulnerable to threats like data breaches, identity thefts, etc. This paper is done with a vision of improving the security standards of the online Passport application process. For such a scenario, a solution based on distributed ledger for storing and retrieving information would work better than the trivial database. The main objective of integrating blockchain technology in the existing passport e-seva portal is to provide maximum security, transparency and immutability. Every level of verification in this process, which is backed by blockchain transactions, is carried out only after the verification and signing by all the authorities involved. Blockchain-based distributed ledger implementation will make the services more streamlined, improving efficiency and potentially lower costs at all levels.
