Description

Non-contact IC card

Technical Field

The invention relates to a non-contact IC card and a method capable of effectively marking, identifying and canceling, belonging to the technical field of non-contact IC cards. .

Background

The non-contact IC card (also called radio frequency card, for convenience of description, hereinafter also referred to as card) is composed of an integrated circuit chip including a memory, an induction antenna, a packaging shell and the like, and the reading or reading and writing operation and the identity recognition of data are completed between the non-contact IC card and a verification device through radio waves, and the non-contact IC card is widely applied to the identity recognition of people, animals, equipment, devices and the like, or the fields of finance, public transportation, medical treatment, campus card, access control and the like, such as resident identity cards, electronic passports, driving licenses, automobile driving licenses, financial cards, campus cards, access control cards, identity recognition cards and the like.

However, due to the characteristic of near-field (generally 5-10 cm) communication reading and writing, even if the card fails in the system (such as the expiration of the identity card or the death of a holder), is lost (such as the loss of the identity card), and is early-warned (such as the pursuit of the holder of the identity card), the card cannot be read, written or cancelled remotely, and can still be illegally used or falsely used; the verification device of the non-contact IC card only has or only opens the information reading function, even if the card certificate in abnormal states such as failure, loss report, early warning and the like can be identified during the networking verification with the background database, the card certificate can not be marked or cancelled, the card certificate can still be repeatedly used illegally, and great troubles, losses and resource waste are caused to card certificate loss persons, certificate use units, public security and judicial departments.

In the prior art and patent documents, no method for effectively solving the problems is found. For example, some schemes design a network query platform to query the issuing date of the card certificates, some schemes assign unique codes to each card certificate to distinguish the card certificates to be subsidized, and the like, but the card certificates which are reported to be lost, invalid and early-warning cannot be marked or cancelled, can still be illegally used again and again, and have difficulties in checking, management and the like.

In view of the fact that in a non-contact IC card system, update information (such as conventional information, certificate making history, loss report records, logout records and the like) stored in a background database can be read in an authorized mode during networking, and the reader-writer technology is quite popular; and the wide coverage of wireless/wired networks, so that the verification device can exchange information with a background database in real time under most conditions, and the problem is solved by a simple method under the conditions of meeting national legal regulations and protecting personal privacy.

Disclosure of Invention

The invention provides a non-contact IC card and a method capable of effectively marking, identifying and canceling, comprising a card certificate, a verification device and a background database; the method is applicable to non-contact IC cards including but not limited to identity cards (such as resident identity cards, electronic passports, motor vehicle running cards, personnel/animal/article identification cards and the like), qualification cards (such as driving licenses, authorization cards, qualification grade cards and the like), pass cards (such as access cards and the like), function cards (such as campus cards, membership cards, financial cards and the like).

The technical scheme for solving the problems is as follows: setting a writing frequency limiting area in a memory of the non-contact IC card, and storing a state code representing the state information of the card in or once in a background database; the verification device can read and rewrite the state code in the card under the set rule; the latest status information of the card holder corresponding to the card certificate is stored in the background database. When the card and the certificate are verified in a networking mode, the state code is read by the verification device and can be compared with current state information in the database, if the two are consistent, or the state code in the card and the certificate is marked as abnormal, or the storage area of the state code in the card and the certificate reaches the upper limit of the allowable writing times, the verifier can be prompted, otherwise, the state code is automatically rewritten according to a preset rule, and the verifier can be prompted.

Setting the limit of writing times of a state code storage area in the card, mainly avoiding the unauthorized recovery of the card marked as abnormal into normal; the upper limit of the writing time limit is determined by the requirement of the card security level and the technical type of the writing time limit area, and can be set to be one time, such as a resident identification card, a driving license, an identification card, an entrance guard card and the like. Any card with abnormal state in the database is automatically identified and marked as long as being read by the networked verification device for the first time, and any verification device for local verification or networked verification can identify and prompt a verifier, so that the card cannot be verified again; the status code and display character representing the card is normal or abnormal can be customized in advance.

The invention has the advantages that the marking, identification or cancellation of the non-contact IC card in abnormal states such as failure, loss report, early warning and the like are effectively realized, and the problems of disturbance and potential loss caused by illegal use of the loss report and failure non-contact IC card to card and certificate loss persons, certificate use units, public security departments, judicial departments and the like, timeliness of blocking the early warning card and the like are solved; the problem of to being blocked the promptness by the early warning card is solved.

Detailed Description

The following examples are illustrative only and are not to be construed as being exhaustive or limiting of the invention; all other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of protection of the present invention.

The implementation of the invention comprises three parts of a non-contact IC card, a background database and a verification device:

firstly, defining a state code representing card state information so as to be convenient for display and identification, and corresponding to a binary code actually stored in a memory. For example, the character N represents normal, X represents abnormal, R represents loss, C represents logout, 0/1/2/3.. represents first/second/third proofs.. the proofed version, etc., respectively; of course, a binary code may be used directly.

Secondly, establishing a writing time limit area and a status code in the non-contact IC card:

establishing a write-in time limit area in a memory chip of the card certificate in a physical or software mode, setting a time upper limit which can be written in by a verification device, and writing initial information during card certificate making:

the physical mode is as follows: when the card is designed and manufactured, the memory of the card corresponds to part or all of the writing time limit area and is manufactured by adopting a one-time programmable read-only memory process, such as PROM, OTPROM and the like. The manufacturing process determines that the upper limit of the writing times of the area is 1, namely, the area can be written only once; and the code corresponding to the storage state when leaving the factory is the initial information state code when the non-contact IC card is certified.

The software mode is as follows: when the card is manufactured, the memory can adopt a multi-time writing type memory, such as an EEROM (electrically-written and electrically-erased read-only memory), an EPROM (electrically-written and ultraviolet-erased memory) and the like, but when the card is manufactured or manufactured, a certain storage space is allocated to be a writing time limiting area to store an initial state code, a program counter is used for presetting the upper limit of the writing time allowed in the area, the counter automatically adds 1 every time the writing is performed, and when the upper limit of the writing time allowed in the area is reached, the writing in the area is automatically forbidden.

Thirdly, establishing state information by the background database:

and establishing a representative card state code or state information corresponding to the card state code in a background database.

Fourthly, the verification device:

the card has the functions of reading/writing, can read the state code in the card, can compare the state code with the current state information in the database during the networking verification, and the two are consistent, or the state code in the card is marked as abnormal, or the storage area of the state code in the card reaches the upper limit of the allowable writing times, so that the verifier can be prompted to verify the result, but the rewriting of the state code in the card is automatically forbidden; otherwise, the state code is automatically rewritten into the state code representing the abnormity according to the preset rule, and the verifier can be prompted.

The old of the original verification device: and for the verification device with the read/write function, upgrading the software to enable the verification device to have the function. For a verification device without a writing function, software and hardware are upgraded, so that the verification device can be written on the basis of the original function and has the functions; or only software is upgraded, so that the state code can be read in the card certificate, and the verifier is prompted, in this case, the verification device has a verification function and can recognize the marked card certificate although the card certificate cannot be written in.
