Fake Passport Detection Using Blockchain

Despite technological advancements, the problem of fake passports is still being faced by many countries all over the world. In order to tackle the menace of passport forgery, technical solutions are being used by passport-verifying authorities. Passport verification is carried out in two ways. One way is by checking the material of the passport and various signs on the physical passport, and the other is by verifying the authenticity of information mentioned on the passport. It has been observed that many times that passports are forged by manipulating the information, a person's image, or a person's signature on the passport. Though this information on the passport is verified by verifying authorities against the passport's information stored in the digital system, the management of the digital information of the passport is not free from unauthorized access or manipulation of the digital information of the passport. Also, currently, citizens' passport data verification is done mainly by airport authorities during passenger undertaking flight travel. However, apart from that passports are considered valid proof document for many processes and by many corporates and organizations in the country. Nevertheless, as of today, there is no means available by which third parties or corporates can verify all the passport information of the passport or passport copy provided to them. Thus in this paper, we have discussed the design and implementation of a blockchain-based system for managing passport-related information. Also, through this system, various stakeholders such as airport verification authorities, corporates, organizations and others are connected and can access passport-related information for verification purposes. This system can be used to verify the authenticity of passport data by different stakeholders, and based on it, these stakeholders can identify fake or forged passport data provided to them.
