Device and method for identifying IC card

Abstract

A device and method for identifying an IC card, the device includes an IC card reader, a microprocessor, a test UID card, a card issued by a bank, a power supply module, a display module, an automatic alarm device, etc., and first obtains the user IC card 0 sector 0 The data readout time of the block data and other sector data is compared with the data readout time of the IC card issued by the bank to determine whether it is within a certain range, so as to determine whether the IC card is a normal card, and realize the anti-theft of the IC card Function; first test the UID card to judge whether the system is working normally, if it is normal, the user can operate the IC card, when the IC card is identified as an abnormal card, the system prohibits the card from reading and writing, and sends a message to the user Mobile phones and public security organs send IC card leakage prompt information; the device for identifying IC cards provided in the present invention is simple and clear in principle and operation, can accurately judge whether the information of the IC card is leaked, and greatly improves the safety and security of the IC card. confidentiality.

Description

technical field [0001] The invention belongs to the technical field of IC card security, in particular to a device and method for identifying an IC card. Background technique [0002] At present, with the rapid development of digital information, IC cards, as one of the carriers of digital information, are common in people's daily life, such as bus cards, bank cards, telephone cards and access control cards that people usually use. While the IC card provides convenience to people's life, it also brings opportunities for some criminals to take advantage of. The incidents of stealing IC card information for huge profits by illegal means happen from time to time, and what's more, using forged IC cards Cards carry out criminal activities, bringing great potential safety hazards to people's lives and property, so the security of IC cards has always been a hot spot of social concern. The commonly used security measure on the market is to encrypt the IC card, but this encryption m...

Problems solved by technology

The commonly used security measure in the market is to encrypt the IC card, but this encryption method is easy to be cracked by criminals, and then forged false data, causing immeasurable losses to users

[0003] The IC card is mainly composed of 16 sectors, and each sector has 4 blocks. The data reading and writing of the IC card is realized through the operation of each block. The data of the 0 sector and 0 block of the ordinary IC card is formulated by the manufacturer. Intrinsic data, limited to write operations
