The CPU card can be applied to many fields such as finance, insurance, traffic police, and government industries. The appearance of the CPU card is the same as that of ordinary IC cards and radio frequency cards, but the performance has been greatly improved. Compared with ordinary IC cards, CPU cards have greatly improved , improve a lot, usually the CPU card contains random number generator, hardware DES, 3DES encryption algorithm, etc., cooperate with the operating system that is on-chip OS, also known as COS, can reach the financial level security level, but the cost is very high, it is difficult to use it in the community Application in the access control system
The scheme of dynamic password is to regularly modify the card reading key of the system to realize the anti-copy function. However, this scheme cannot be realized across devices. The units are all connected, so the access control card of the building needs to be used on the access control devices of the two units. This kind of application scenario cannot realize the anti-copy function well, and the copied card will be locked before the next password change. During this period of time, it can still be used continuously, and cannot effectively limit the use of copy cards in time
To identify the cloned card is to identify the cloned card directly on the card reading device. Once the cloned card is recognized, the data inside the cloned card will be changed to data without permission. Unrecognizable clone card, which leads to the inability of this solution to work, and the identification of the clone card also requires a specific card reader device that supports the identification of the clone card

[0019] Please refer to figure 1 , is a schematic diagram of the interaction between the management server 10 provided by the first embodiment of the present invention, the card reading device 20 and the electronic card 30 . The management server 10 can process the data in the electronic card 30, identify the identity of the user, and can also communicate with the building intercom. The management server 10 may be a personal computer (personal computer, PC), etc., and the operating system of the management server 10 may be, but not limited to, a Windows system. The card reading device 20 can be a card reader, which can be applied to the access control systems of residential quarters and office buildings.

[0020] After the user holds the electronic card 30 to swipe the card on or around the card reading device 20, the card reading device 20 sends the information of the electronic card 30 to the management server 10, and the management server 10 is responsible for the informati...

[0040] Please refer to Figure 5 , is a flow chart of the electronic card 30 anti-copy method provided by the second embodiment of the present invention. The electronic card 30 anti-duplication method of this embodiment is applied to the management server 10, and the method includes:

[0041] Step S101 , write the unique identification code and the number of card reading marks into the electronic card 30 .

[0042] Before distributing the electronic card 30 to the user, the management server 10 will authorize the electronic card 30 and write the unique identification code and the number of times of card reading into the electronic card 30 . The unique identification code only corresponds to one card, and the unique identification code of each authorized electronic card 30 is stored in the memory 101 . The electronic card 30 has a storage area, which can include an A area and a B area. The specific mode of writing the unique identification code and the number of card reading ...

Abstract

The invention provides an electronic card anti-copy method and device, and a management server and relates to the access control technology field. Special identifier data is written into electronic cards to prevent the electronic cards from being copied. Non-contact IC copy cards in the market at present can be all identified, even including cloned cards, moreover, reading and writing operation of common IC cards can be realized, no extra cost is required, the common IC cards can be read through IC card reading equipment, namely common card readers, and extra function cost is not required; anti-copy functions of all the readable cards can be realized through the electronic card anti-copy method. The electronic card anti-copy method has advantages of high identification degree, low cost and wide application scope.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an electronic card copy prevention method, device and management server. Background technique [0002] Existing access control cards are easy to be copied by users, which is inconvenient for property management companies to manage, and poses a great security risk to communities, office buildings and other places where access control is set up. Existing existing access control card anti-duplication methods have methods such as adopting CPU card, dynamic password, identification clone card, etc., and these methods all have defects at present. The CPU card can be applied to many fields such as finance, insurance, traffic police, and government industries. The appearance of the CPU card is the same as that of ordinary IC cards and radio frequency cards, but the performance has been greatly improved. Compared with ordinary IC cards, CPU cards have greatly improved , improve a ...
