THE METHOD FOR PREVENTING FROM CLONE AND FRAUD OF THE CONTACTLESS INTEGRATED IC CARD

摘要

The present invention relates to a method for preventing duplication and data tampering of a smart card, and more particularly, to a method for preventing duplication and data tampering of a smart card by encrypting data embedded in a smart card through a reader. To this end, the present invention comprises the steps of installing a second encryption algorithm in the RF card reader or charger; And when using the RF card in a reader or a charger, storing the encrypted data on the RF card using a second encryption algorithm installed in the RF card reader or the charger. Accordingly, according to the present invention, it is possible to improve security by encrypting a smart card with a new encryption algorithm, and it is possible to prevent copying of My Pair card and preventing data forgery without a separate device or card collection.
