Embodiment
embodiment mono-:
The present embodiment provides off line terminal transaction data back up method in a kind of payment system, and as shown in Figure 1, it comprises the following steps:
Smart card obtains the terminating machine numbering that need to conclude the business with it;
Terminating machine sends the instruction of backup transaction record to described smart card;
Travel through the transaction record in described smart card, judge in described smart card, whether to comprise the transaction record not yet backing up in this station terminal machine;
As judgment result is that, be to continue to judge the transaction record that whether comprises non-described smart card and described terminating machine transaction generation in described smart card;
As smart card does not comprise the transaction record not yet backing up in this station terminal machine as described in judgment result is that, generates instruction return data, generate and return " without the backup transaction record " instruction of described for replying " instruction of backup transaction record ";
As described in judgment result is that smart card comprise non-as described in the transaction record that produces of smart card and the transaction of this station terminal machine, generate instruction return data, generate and return the instruction of " need to back up transaction record " of described for replying " instruction of backup transaction record ";
Described smart card is sent to the non-described smart card of this part and described terminal transaction and the transaction record that not yet backs up in described terminating machine in described terminating machine, and described terminating machine backs up this part transaction record;
As described in judgment result is that, in smart card, do not comprise non-as described in the transaction record that produces of smart card and the transaction of this station terminal machine, generate instruction return data, generate and return " without the backup transaction record " instruction of described for replying " instruction of backup transaction record ";
After having backed up, the backup sign of the described transaction record in described smart card is revised as and is backed up;
Described smart card and described terminating machine are concluded the business;
Described smart card and described terminating machine back up respectively this transaction record.
The method of the present embodiment is applicable to the terminal of offline transaction in payment system, is for off line termination property the transaction record back mechanism that proposes in conjunction with the problem running in practical application.Lifting with respect to the terminal hardware storage capacity of current main flow, knapsack back mechanism is based upon in existing terminal-based, only by introducing novel backup method, reduce half loss of data probability, fill up the blank that causes the precautionary measures of a large amount of transaction records loss because of unpredictable equipment loss, and increased hardly the cost that safe storage ensures.
In practical application, before occurring, new transaction increased the backup of having communicated by letter transaction record of card with terminal.Transmission information amount is little, and flow process is simple, and this process is almost ND, does not also affect the serviceability of terminal in true environment.When deal with data gathers, normal transaction data and Backup Data are distinguished, also only when there is loss of data, just use Backup Data, can not cause data redundancy, therefore do not affect statistical efficiency.
The method of the present embodiment is a kind of knapsack back mechanism, its essence is by card and guide, on its Consumption Path in storage card a kind of multi-point backup mechanism of transaction record as shown in Figure 2, the principle of the knapsack back mechanism of the present embodiment is:
A is stuck on first machine and consumes, and transaction record is kept on A card and first machine simultaneously; When A card next time is when consuming on second machine, second prow first sends transaction record backup instruction to A card, the transaction record that non-the machine in A card is consumed and do not backed up in the machine backs up to the machine, and the backup sign of this part record in A card is revised as and is backed up, and starts afterwards new process of consumption.The rest may be inferred to the third machine, fourth machine etc.When having terminal generation loss of data, just can in the data of other-end, recover transaction record by backup.This mechanism is by the double shield at different terminals by transaction record backup, reduced to a great extent terminal device in use because the transaction record that physical damage or other reasons cause is lost the loss bringing.
