Abstract:
Currently, in this digital world, the passport is still a physical entity. Each passport contains
various security and identity attributes to figure out the owner of the passport and also
circumvent attempts at tampering with the passports. Fake passports are usually copies of
genuine passports that are illegally modified by an unauthorized person. The most individuals
get genuineness to show counterfeit visas. The system was unable to identify these fake
passports. The individuals deceitfully acquired realness to their fake travel papers that expected
genuine. And day by day this number increased with a large range. As a result, criminal
activities have grown such as trafficking, smuggling, identity theft and so on. Currently, there
is no mechanism available to immediately blacklist or revoke a suspected passport. It’s a big
challenge especially for Bangladesh to identify travel documents and made border control
systems more secure. By using Blockchain Technology we will try to reduce the following
problems. It is producing a wide scope of chances and potential outcomes in current travel
document verification services. Blockchain is an unbribable peer-to-peer network that permits
multiple validators/verified agencies to transfer value in a secure and transparent way. Our aim
is to propose a decentralized application and all validators have to connect through the
distributed ledger. To verify a passport each validator bet on the blocks and added to the chain.
The validators mining the blocks continuously unless found any anomalies, if one validator
gets any suspicious issue then the passport included in the blacklisted list. Moreover, we will
be trying to maintain a passport list in a smart contract and if there any changes occurred then
it will be immediately visible by all validators. In blockchain technology data is immutable and
distributes the entire network to be encrypted format, so data breached is not possible. Also,
make services more elegant and increasing efficiency.
