Intelligent IC card data detection method and device

Abstract

The invention provides an intelligent IC card data detection method and device which are applied to a card writing terminal. The method comprises the following steps that: personalization data are converted into a personalization APDU (Application Protocol Data Unit) instruction; the personalization APDU instruction is sent to an intelligent IC card through a secure channel, and the feedback information of the intelligent IC card is acquired; consistency comparison is performed on the feedback information, and comparison information is obtained; and a personalization process is interrupted or terminated according to the comparison information. The device includes an instrument generation module, a data interaction module, a verification module and an execution module; the instrument generation module is used for converting the personalization data into the personalization APDU instruction; the data interaction module is used for sending the personalization APDU instruction to the intelligent IC card through the secure channel and obtaining the feedback information of the intelligent IC card; the verification module is used for performing consistency comparison on the feedback information so as to obtain the comparison information; and the execution module is used for interrupting or terminating the personalization process according to the comparison information. With the intelligent IC card data detection method and device of the invention, a condition that the actually received data and stored data of the intelligent IC card in a personalization stage are inconsistent with original data provided by a client can be avoided.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a smart IC card data detection method and a device applying the method. Background technique [0002] For the personalization of the smart IC card (Intelligent card), during the communication process between the card writing terminal and the chip, especially the non-contact communication process, it may be disturbed by static electricity or other factors, resulting in the data actually stored in the IC card inconsistent with the original data. For example: the data is tampered with during the process of sending the terminal program to the chip, or the data is inconsistent with the original data due to damage to individual storage tracks inside the chip. [0003] The current COS (Chip Operating System, card operating system or smart card system) manufacturers, taking financial applications as an example, the chip COS receives the data and stores it in the card, and then retur...

Problems solved by technology

However, for mass-produced smart IC cards, it is difficult to achieve full inspection, especially for some sensitive data. The customer provides ciphertext. When writing the card, it is encrypted and written to the card. After personalization, it is difficult to verify. Moreover, the data cannot be read out for verification after personalization. If there is a problem with an individual card in a batch of cards, it is difficult to be detected by random inspection. Such problems directly affect the quality evaluation of the entire batch of cards
