[0064] figure 1 It is a schematic flow chart of a card reading processing method provided in the first embodiment of the present invention. This method is applicable to the scene where a card reading device reads an IC card, and can be executed by a card reading processing device, wherein the device can be implemented by software and / or hardware Realized, and generally can be integrated in the card reader device.

[0065] The method of this embodiment specifically includes:

[0066] Step 110, when it is detected that the IC card enters the card reading environment, verify the compatibility between the IC card and the card reading device;

[0067] In this embodiment, entering the card reading environment specifically refers to the insertion of the contact IC card into the card reading device or the entry of the non-contact IC card into the card reading range of the card reading device, wherein the card reading range specifically refers to the card reading range of the card rea...

[0078] figure 2 It is a schematic flowchart of a card reading processing method provided by the second embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, the matching of the verification of the IC card and the card reading device is optimized as follows: obtaining the data to be decrypted stored in the IC card; using a local key Decrypt the data to be decrypted; analyze the data structure of the decrypted result, if the analysis determines that the decrypted result conforms to the set data structure, then determine that the IC card matches the card reading device.

[0079] Correspondingly, the method in this embodiment specifically includes:

[0080] Step 210, when it is detected that the IC card enters the card reading environment, obtain the data to be decrypted stored in the IC card;

[0081] In this embodiment, the data to be decrypted stored in the IC card specifically refers to data st...

Abstract

Embodiments of the invention disclose a card reading processing method and apparatus. The method comprises the steps of verifying the matching property of an IC card and a card reading device when it is detected that the IC card enters a card reading environment; if it is determined that the IC card is matched with the card reading device, performing cloned card identification on the IC card according to a response condition of the IC card for a chip identifier modification instruction; and if it is determined that the IC card is a legal IC card, adopting a permission opening policy corresponding to a permission request of the IC card, and opening a permission for an IC card user. According to the card reading processing method and apparatus, the card reading processing method is optimized, so that a cloned card can be identified on the premise of not destroying IC card data, and the user loss is reduced.

Description

technical field [0001] The embodiment of the present invention relates to data processing technology, and in particular to a card reading processing method and device. Background technique [0002] IC card (Integrated Circuit Card), also known as smart card, smart card, microcircuit card or microchip card, etc., it is made into a card form by embedding a microelectronic chip in a card base conforming to the ISO7816 standard. Due to its inherent information security, portability, relatively complete standardization and other advantages, IC cards have been used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management, such as second-generation ID cards, bank cards, etc. Electronic wallets, SIM cards for telecom mobile phones, bus and subway cards for public transportation, parking cards for parking fees, etc., play an important role in people's daily life. [0003] Generally speaking, the serial nu...
