Embodiment
under typical on-line transaction pattern, data handling system and transaction terminal (for example supplementing treatment facility with money) establish a communications link through network.For example, when needs are modified (charging intelligent card operation) to intelligent card data, the personal data being associated with this smart card or the first data that first data handling system preserves in Update Table storehouse.Subsequently, data handling system sends and revises order to transaction terminal, and personal data or second data of preserving in smart card are revised in indication.Obviously, first and second data should be consistent or corresponding relation, also keep synchronous.Preferably, data handling system writes in script file by order and sends to transaction terminal.As response, transaction terminal is resolved script file and the order of extraction is sent to smart card.Smart card is revised the second data and the response message that comprises result is returned to transaction terminal according to the order of extracting, and transaction terminal is sent to data handling system by result again.If result is the second data, successfully revised, data handling system will be confirmed the previously modification to the first data in database, thereby realize synchronous between first and second data.
but for some reason, the unsuccessful modification that completes the second data of smart card possibility, or do not return to response message (now the second data may successfully be revised, and also may successfully not revised).In the broadest sense, above-mentioned two kinds of abnormal case all can be regarded as revising unsuccessfully, but according to embodiments of the invention, and they are the result type that is regarded as belonging to different, and correspondingly, in data handling system side, will adopt different processing policies.Particularly, when smart card is unsuccessful when completing the modification of the second data but returning to response message, data handling system reverts to state before modification to keep and the synchronizeing of the second data by the first data in database; When smart card does not return to response message, data handling system is the modification that has defect by the modified logo of the first data, to further processing in the future.According to embodiments of the invention, under rear a kind of result type, data handling system can revert to the state before modification by the first data in database, also can not revert to the state before modification, but there is defect owing to being identified as, so can judge according to the transaction record in smart card whether the second data are successfully revised, and determine whether accordingly to change the first data.
as mentioned above, can be by sending to the script file of transaction terminal to realize to the modification of data in smart card.According to embodiments of the invention, can adopt following hierarchical model to describe the processing of transaction terminal to script file: the processing of transaction terminal is divided into Physical layer and two levels of application layer, wherein, in Physical layer, transaction terminal judgement smart card is carried out and is revised the state of order and transmit corresponding status information to application layer, if for example smart card returns to response message, judge that smart card is in carrying out the state of revising order, and if smart card does not return to response message in transaction terminal sends the setting-up time section of revising after order, judge the state of smart card in result the unknown, in application layer, the status information that transaction terminal transmits according to Physical layer is carried out different processing policies, if for example smart card is carried out the state of revising order in, transaction terminal generates retouching operation failure or successful message and sends the message of generation to data handling system, if the state of smart card in result the unknown, transaction terminal generates the message of result the unknown and sends the message of generation to data handling system.
when the unsuccessful result that completes the modification of the second data and do not return to response message of smart card is not added and distinguishes and when data handling system side adopts identical processing policy, likely make publisher bear financial risks.Particularly, for example supplementing with money under operation, when smart card successful execution the second data modification but while not returned to response message, if thinking, data handling system there is the situation of the second data modification failure and makes thus the first data return to revise front state, by the remaining sum that causes off line account balance in smart card higher than backstage account in data handling system, thereby form shortage of money.By comparison, according to embodiments of the invention, when smart card successful execution the second data modification but while not returned to response message, data handling system can be configured under default situation, state before the first data can not return to and revise and be only by this modified logo for there being defect, stopped thus the possibility of the off line account balance in smart card higher than backstage account balance in data handling system.
referring to accompanying drawing, embodiments of the invention are described.
fig. 1 revises the process flow diagram of the method for data in smart card according to the transaction terminal that utilizes of one embodiment of the invention.
as shown in Figure 1, at step S101, transaction terminal receives the order of carrying the on-line transaction message of script file and extracting personal data in the modification smart card comprising script file from data handling system.Exemplarily, the personal data that hypothesis is revised is here off line account balance.
then enter step S103, transaction terminal sends the order of revising off line account balance to smart card.Need to go out, may comprise many and revise order in a script file, now transaction terminal can be sent to smart card one by one by it.
subsequently, at step S105, transaction terminal is carried out physical layer operations,, whether the setting-up time inner segment of judgement after sending modification order receives the response message from smart card, comprises the result whether smart card has successfully revised off line account balance in this response message.If the response message of receiving, enters step S107, otherwise, step S115 entered.
at step S107, transaction terminal is carried out application layer operation, parsing is sent to the smart card response message of application layer from Physical layer, and according to the result comprising in response message, judges whether smart card has successfully completed the modification of off line account balance in step S109.If response message indication is successfully modified, enter step S111, transaction terminal sends to data handling system the message that script file is successfully executed or off line account balance is successfully revised, otherwise, enter step S113, transaction terminal is not successfully executed or off line account balance modification failure to data handling system transmission script file.
get back to step S105 another branch afterwards, in step S115, the Physical layer of transaction terminal transmits the status information that does not receive smart card response message to application layer, and subsequently at step S117, transaction terminal sends the message of script file execution result the unknown or the unknown of off line account balance modification result to data handling system.
after completing steps S111, S113 and S117, treatment scheme will finish.
