Automated Border Control System using Blockchain Technology

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.
