Description
Technical field
The present invention relates to the applying in radio frequency identification technical field, relate in particular to the terminal of contact type intelligent card and handle unusual method.
Background technology
Present consumption smart card has a variety of, and radio-frequency SIM card (RFSIM) is arranged, and is the mobile phone intelligent card of wireless near field communication in can realizing; Contactless CPU card is arranged, and is a kind of contactless IC-card, can realize short-range communication, or the like.In addition; Also have a kind of contactless logic encryption card, the difference of it and smart card is: in smart card, have microprocessor (MPU owing to there is one; Micro-Processor Unit) integrated circuit; So except having bigger memory capacity, also possess certain data processing capability, it is higher to use safety of data; And contactless logic encryption card only has data storage function, does not possess data-handling capacity, and its security is prone to be cracked, just because its cost is lower, so still do not substituted by smart card fully at present.
Along with the development of technology of Internet of things, the application scenarios of REID becomes increasingly complex, for example with application of IC cards in all kinds of consumption, various intelligent cards will progressively substitute original contactless logic encryption card.Simultaneously, in order to satisfy various consumption demands, the situation of combination wallet in a sheet smart card sheet has appearred; For example in enterprise; The wallet that is used for dining room consumption in employee's the smart card has two, and one is to be used to deposit the subsidy that enterprise provided in every month, and one is to be used to deposit individual recharge amount etc.In addition, also have the situation that multiple wallet is arranged in the sheet smart card, for example be used for the mass transit card of transit riding consumption, simultaneously can be in some supermarkets purchase and consumption etc.In patent 200910092488.4, once mentioned the application problem that smart card is set up many wallets, but this patent is only to tell about how to expand many wallets from the angle of smart card.
In real world applications, the mode that the common utilization smart card of people is consumed has two kinds, and a kind of is on-line transaction, and another kind then is an offline transaction.Wherein, The accounts information of on-line transaction is to be stored in background server; The user is the unique identification (card number of smart card) through smart card when concluding the business; Confirm the accounts information on its background server, so the terminal need not to be equipped with consumption safety access module (PSAM, Purchase Secure Access Module); The accounts information of offline transaction is to be stored in the smart card, so just need on the terminal, be equipped with PSAM, is used for the data of transaction are carried out safety certification, and is as shown in Figure 1.Because the terminal need not as on-line transaction, frequently to carry out alternately with background server in carrying out process of exchange, so the range of application of offline transaction consumption is more more wide than on-line transaction.
As can be seen from Figure 1; Smart card and terminal communicate through eating dishes without rice or wine, because transaction relates to the reimbursement of expense problem, so; Safety certification need be carried out to data through PSAM in the terminal in process of exchange, and all data of transaction at last can be through Network Transmission to background server.
Contact type intelligent card may run into following problem in carrying out transaction communications process:
The first, in process of consumption, terminal works is normal, but smart card may leave the induction zone at terminal unusually;
At this moment, the terminal notifies the user that smart card is put back on the induction zone at terminal again, treats that the terminal searches this smart card again; And confirm as be just employed smart card after, obtain the second required message authentication code of verification msg (MAC2, MessageAuthentication Code 2) information through the smart card verification command of PSAM from smart card; With the legitimacy of checking transaction, if MAC2 Information Authentication success explains that transaction takes place; Promptly corresponding fund is detained in the accounts information of smart card; This moment, the terminal was in the database of this recording storage to the terminal, and PSAM will generate new transaction journal number, accomplish and conclude the business.
The second, in process of consumption, the terminal may sudden power;
At this moment, if the mode of leaving the induction zone at terminal unusually according to above-mentioned smart card prevents pulling out processing, then can't be through the checking of PSAM, reason is that the initialization information of former PSAM is lost when having cut off the power supply at the terminal.And not only current transaction can't confirm, makes up purse transaction simultaneously and also can't confirm to which in step.
At this, the terminal is prevented pulling out processing and is meant when the transaction abnormal ending in process of exchange, occurring, guarantees the conforming way of concluding the business.The consistance of transaction is meant that the processing through the terminal makes that the Transaction Information on the smart card is consistent with the Transaction Information on the background server.
In patent CN01130114.7 and patent CN200510025030.9; Described the anti-disposal route of pulling out of contactless logic encryption card, but still can't solve the above-mentioned root problem of concluding the business and can't proceed of occurring causing unusually at process of exchange owing to there is following problem in it:
(1) these two patents are described all is the anti-disposal route or the data reconstruction method of pulling out of contactless logic encryption card; Rather than the anti-disposal route of pulling out of smart card or radio-frequency SIM card; Because the difference of the structure of two types of cards is so the former processing mode can not be transplanted to the latter.
(2) these two patents are only told about is that contactless logical encrypt cacaine is rocked the processing that the transaction that caused behind the induction region that shifts out the terminal is carried out unusually, and do not comprise for the terminal unusual under the electrifying condition and at the terminal unusual anti-during sudden power pull out processing.
(3) these two patents are not all mentioned the anti-disposal route of pulling out that a sheet smart card has the terminal of many wallet consumption.
This shows, the terminal of existing contact type intelligent card and handle unusual method and need improve, make its can be directed against smart card, terminal carry out unusually anti-ly accordingly pull out processing, and can be adapted to easily in the terminal of the many purse transactions of a card.
