Card reader anti-counterfeiting method and card reader anti-counterfeiting system

Abstract

The invention provides a card reader anti-counterfeiting method and a card reader anti-counterfeiting system. The card reader anti-counterfeiting method comprises the following steps: receiving and storing production test information and function authorization information of the card reader; when the card reader is started, performing hardware self-inspection on the card reader to obtain self-inspection information; comparing the self-checking information with the production test information, if the self-checking information is consistent with the production test information, judging that thecard reader is legal equipment and normally starting up the card reader, otherwise, judging that the card reader is fake equipment and stopping starting up the card reader; after the card reader is normally started, verifying whether the function authorization information is legal or not according to an authorization verification algorithm, if yes, determining and activating the authorized function according to the function authorization information, and if not, locking all the functions. The anti-counterfeiting capacity of the card reader can be improved, and the card reader is effectively prevented from being forged.

Description

technical field [0001] The invention relates to the technical field of card readers, in particular to an anti-counterfeiting method for a card reader and an anti-counterfeiting system for a card reader. Background technique [0002] Integrated Circuit Card (IC card), also known as Smart card, Intelligent card, Microcircuit card or microchip card. It is made into a card form by embedding a microelectronic chip in a card base conforming to the ISO 7816 standard. [0003] Due to its inherent advantages of information security, portability, and relatively complete standardization, integrated circuit cards are being used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management, such as second-generation ID cards, Electronic wallets in banks, mobile phone SIM cards in telecom, bus and subway cards in public transportation, and parking cards used to collect parking fees all play an important role in peo...

AI Technical Summary

Problems solved by technology

[0005] At present, the anti-counterfeiting of card reader products mainly adopts the method of setting a unique device identification number (Identity document, ID), that is, an anti-counterfeiting chip is set in the card reader product, and the anti-counterfeiting chip has a unique identification number. , only after the identification number is identified, the product can work normally. Although this method can achieve a certain anti-counterfeiting function, the defects of this method are also very obvious. Specifically, this method cannot prevent copying. The imitator can copy the smart device after calling the genuine ID number, and become the same ID number of multiple card reader products
