Privacy and security protection of RFID data in e-passport

E-passport is a biometric passport that combines both paper and electronic chip. It includes biometrics information and ID using RFID chip or tag. The goal of e-passport is to provide strong authentication through documents that unambiguously identify the passport holder. An e-passport can protect forging of ID and can make rapid progress in immigration. The use of RFID tag may cause privacy violation of users using the tag. Due to the unique identification number of the RFID tag, this is subjected to different privacy and security threats such as information leakage of a tag, traceability of the person, denial of service attack, and impersonation of a tag. This paper investigates different privacy and security problems in RFID systems used in e-passport and proposes the implementation of a proposed authentication protocol to overcome those privacy and security problems. Simulation experiments show that the protocol is secure for larger entropy.
