E-Passport Advanced Security Technique Using Biometric Information Watermarking

Abstract

There has been significant research in security of e-passport. E-passport combine the security technologies such as smartcard, PKI, and biometric, so that these technologies can prevent unauthorized copies and counterfeits. We propose an e-passport security technology in which biometric watermarking is used to prevent the copy of biometric information in the e-passport. The biometric watermarking embeds the invisible date of acquisition into the original data so that the human visual system cannot perceive its invisibly watermarked information. Then the biometric sample, having its unauthorized copy, is retrieved at the moment of reading the e-passport from the issuing database. The previous e-passport security technology placed an emphasis on both access control readers and anti-cloning chip features, and it is expected that the proposed feature, copy protection of biometric information, will be demanded as the cases of biometric recognition to verify personal identity information has increased. This study proposed test results through issuing and deciphering of watermarks for e-passports, and it is expected that it can be used as standards for protecting biometric information.
