The first copy protection identification can be any integer of 1 byte or a plurality of bytes; for example: can be defined as: 4 bytes RTC time +2 bytes random number, and each IC card is different from each other.
During use of the IC card, i.e., when the IC card is in a real-time reading state,
step 501, the access control device reads information in an IC card through a card swiping module to obtain a current card number and a current anti-copy identifier of the swiped IC card, and sends the obtained card number and the current anti-copy identifier to a server;
step 502, the server obtains a first anti-copy identifier corresponding to the card number according to the current card number, namely, matching the current card number with a prestored first card number, and finding out the corresponding first anti-copy identifier according to the matched first card number; then, the current anti-copy identifier is compared with the searched first anti-copy identifier, if the current anti-copy identifier is the same as the searched first anti-copy identifier, the current anti-copy identifier is determined as a normal card, that is, a non-copy card, step 503 is executed, otherwise, the current anti-copy identifier is determined as a copy card, the determination result is notified to the access control device, and then step 504 is executed.
Step 503, the server determines whether a first anti-copy identifier update condition is satisfied, where the update condition may be that whether a time for updating at regular time is reached is determined according to the system time, or that updating is triggered every time a card is swiped, or that a logic needs to be run according to the server.
And if the updating condition is met, updating the first anti-copy identification of the IC card, storing the updated first anti-copy identification, sending the updated first anti-copy identification to the access control equipment, writing the updated first anti-copy identification into the current IC card by the access control equipment, and sending the judged result to the access control equipment to trigger the access control equipment to judge the access right, namely judging whether the current IC card has the access right for opening the current access control.
And if the updating condition is not met, sending the judged result to the access control equipment so as to trigger the access control equipment to judge the access control authority.
When the access control equipment receives the updated first anti-copy identification from the server, the access control equipment writes the updated first anti-copy identification into the card through the card swiping module, when the updating is successful, the door opening authentication permission result is prompted, the access control is controlled to be opened, and when the updating is unsuccessful, the card swiping is prompted again to ensure that the updating is completed.
When the access control equipment only receives the judgment result from the server and does not have the updated first anti-copy identification, the access control equipment prompts an access authentication permission result and controls the access control to be opened.
And step 504, when the judgment result is the copy card, the access control equipment generates a report event, and reports the current card number and the event attribute of the copy card carried in the report event to the intelligent card operation and maintenance equipment, and simultaneously outputs a prompt through a light prompt module and/or a sound prompt module.
By checking the anti-copy identifier, the method reduces the harm of malicious decoding of the IC card, improves the safety of the system, improves the decoding cost of the IC card and has wide compatibility with the existing IC card on the basis of the existing IC card; in the application of access control management, the intellectualization of property management and operation and maintenance is realized, the proprietary duplication of an IC card by an owner is avoided, and the management of issuing the card is facilitated.
Example two
In order to reduce the resource occupation of the server, the invention provides another embodiment two, and referring to fig. 6, fig. 6 is a flowchart of preventing the IC card from being copied according to another embodiment two of the invention. The initialization process of the IC card is the same as that of the first embodiment.
In the course of use of the IC card,
step 601, the entrance guard equipment reads information in the IC card through the card swiping module to obtain a current card number of the swiped IC card and a current anti-copy identifier, judges the entrance guard authority of the current IC card according to the current card number, sends the obtained card number of the current IC card and the current anti-copy identifier to a server to judge the anti-copy if the entrance guard authority exists, and otherwise, ends.
Step 602, after receiving the card number of the current IC card and the current anti-copy identifier, the server obtains a first anti-copy identifier corresponding to the card number according to the current card number, compares the current anti-copy identifier with the found first anti-copy identifier, if the current anti-copy identifier is the same as the found first anti-copy identifier, determines that the card is a normal card, that is, a non-copy card, performs step 603, otherwise determines that the card is a copy card, notifies the access control device of the determination result, and performs step 604.
Step 603, the server determines whether a first anti-copy identifier update condition is met, wherein the update condition may be that whether the time for updating at regular time is reached is determined according to the system time, or that updating is triggered every time a card is swiped, or that the server runs logic requirements according to the server.
And if the updating condition is met, updating the first anti-copy identification of the IC card, storing the updated first anti-copy identification, sending the updated first anti-copy identification to the access control equipment, writing the updated first anti-copy identification into the current IC card by the access control equipment, and sending the judged result to the access control equipment.
And if the updating condition is not met, sending the judged result to the access control equipment.
When the access control equipment receives the updated first anti-copy identification from the server, the access control equipment writes the updated first anti-copy identification into the card through the card swiping module, controls the access control equipment to be opened when the updating is successful, and prompts card swiping again when the updating is unsuccessful so as to ensure that the updating is completed.
When the access control equipment only receives the judgment result from the server and does not have the updated first anti-copy identification, the access control equipment controls the access control to be opened.
And step 604, when the judgment result is that the card is a copy card, the access control equipment generates a reporting event, and reports the current card number and the event attribute that the copy card is carried in the reporting event to the intelligent card operation and maintenance equipment, and simultaneously, outputs a prompt through a light prompt module and/or a sound prompt module.
According to the embodiment, the entrance guard permission is recognized firstly, and then the anti-copy check is carried out, so that interaction between entrance guard equipment and the server can be reduced, processing resources of the server can be saved, the burden of a network side is reduced for a system adopting cloud service, and the processing efficiency of the network side equipment can be improved.
