Design of a passport anti-forgery system based on digital signature schemes

Abstract

The terrorism threat which is conducted by international terrorists who possess forged identities and passports becomes more and more serious and imminent. Traditional methods and techniques of preventing passport from forgery are not effectual enough. This paper proposes a passport anti-forgery system based on the public key signature scheme RSA. The anti-forgery system contains four modules: the passport dada edit module, passport key production module, passport signature module and passport verification module. A private key used for signing is preserved separately by an authorized issue official, and a public key used for verifying is stored into a database which a web server can access. In this way, the anti-forgery property of a passport is equivalent to the security of an adopted public key signature scheme, and the passport is bound with its issue authority tightly.
