The PKD is used to check digital signatures in ePassport chips. How can that help to detect look-alike fraud?
Modern biometric systems are capable of comparing a facial image stored in an ePassport and a live-capture image of a person’s face within a few seconds. Even small deviations typical for look-alike fraud are reliably detected and the person can be directed to secondary inspection. The PKD based ePassport chip signature check determines chip data integrity including biometrics. Validating the chip is essential if you are relying on the facial image stored on the chip, particularly in border control scenarios experiencing high volumes of passengers.
