Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, the functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In several embodiments provided by the off-line prepaid card acceptance terminal remote security wind control management method, it should be understood that the disclosed systems, apparatus and methods may be implemented in other ways. For example, the apparatus embodiments described above are merely illustrative, e.g., the division of the units is merely a logical function division, and there may be additional divisions when actually implemented, e.g., multiple units or components may be combined or integrated into another system, or some features may be omitted or not performed. In addition, the coupling or direct coupling or communication connection shown or discussed with each other may be an indirect coupling or communication connection via some interfaces, devices, or elements, or may be an electrical, mechanical, or other form of connection.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
The transaction parameter item related by the invention is issued by a background core system and is used for controlling a remote terminal to specifically control a zone bit of a certain functional point. Namely, information of each terminal machine, information of transaction process, information of transaction rule and information of prepaid card configured by the background monitoring end.
The related parameter version is a set of a whole set of parameter items which can be configured by a background monitoring end. The parameter version and the transaction parameter item can be updated in real time according to the transaction requirement, the equipment requirement and the user requirement, and the requirements of all parties are met.
As a practical application scene, the A company is a third-party prepaid card operation company, and terminal POS machines are distributed at a large number of cooperated merchants and used for accepting prepaid cards issued by the company. The prepaid card issued by company A is a financial IC card, and a wallet module is built in the card chip, so that the micropayment transaction in an off-line state can be completed rapidly. The method is widely applied to renting, buses, middle and small merchants and the like. The method is an offline application scene, and the acceptance terminal is distributed at the merchant, so that higher requirements are put on terminal wind control prevention. Company a has established a mechanism for secure, remote management of wind controls in a parametric version.
Based on the above description, the invention provides a remote security wind control management method for an offline prepaid card acceptance terminal, as shown in fig. 1, the method comprises the following steps:
s1, establishing communication connection between a terminal and a background monitoring end when a preset condition is met;
the preset conditions referred to herein include:
each time a preset duration passes, the terminal establishes communication connection with the background monitoring end;
or/and the terminal machine establishes communication connection with the background monitoring end when the terminal machine reaches the preset transaction times;
or/and the current transaction of the terminal does not accord with the currently downloaded transaction parameter item, the terminal and the background monitoring end are in communication connection.
More specifically, for example, when the terminal is in an offline state, communication connection needs to be established between the terminal and the background monitoring terminal after a preset time period. The duration here may be one day, one hour, or one week, etc. That is, although the terminal can operate in an offline state, it is necessary to establish a communication connection with the background monitoring end after a period of time passes, so that the background monitoring end obtains each transaction information in an offline state and the current information of the terminal, and determines whether the terminal is tampered or not, and whether the terminal has an illegal transaction process or not.
And communication connection with the background monitoring end can be established according to the offline transaction times of the terminal machine, so that the monitoring of the terminal machine by the background monitoring end is realized.
In the off-line state, the current transaction of the terminal does not accord with the current downloaded transaction parameter item, the subsequent transaction can be carried out after the communication connection between the terminal and the background monitoring end is established, or the terminal is in a transaction stopping state.
The above-mentioned several conditions may exist at the same time, or may be used optionally at one or more.
S2, the terminal machine sends sign-in information to a background monitoring end;
the terminal machine current transaction parameter item, the number of off-line transactions completed by the terminal machine before reaching the preset condition, the time of each off-line transaction and the prepaid card information of the off-line transaction.
Because the system involves a plurality of terminals, after each terminal establishes communication connection with the background monitoring terminal, information such as codes, addresses, identifiers and the like of the terminal needs to be identified, so that the background monitoring terminal can learn the information of the terminal for comparison and confirmation.
Therefore, the background monitoring end can be convenient to know whether the transaction behavior of the terminal machine is legal or not in an off-line state more effectively, and the requirements are met.
S3, the terminal downloads transaction parameter items from a background monitoring end and stores the transaction parameter items and the transaction parameter items locally;
if the background monitoring end adjusts the transaction parameter item according to the service requirement, the terminal downloads the transaction parameter item from the background monitoring end, stores the transaction parameter item and is used in local and offline transactions.
And S4, in an off-line state, the terminal judges whether the transaction is allowed or not according to the currently downloaded transaction parameter item. In the offline state, if the current transaction process meets the current downloaded transaction parameter item, the transaction is normally performed. If not, the current transaction is stopped.
Of course, the method is not limited to the transaction, but can also involve the addition, deletion and correction of prepaid card information and terminal information in an offline state, and if the added, deleted and correction is illegal, namely, the currently downloaded transaction parameter item is not satisfied, the corresponding operation cannot be performed.
The method and system for remote secure wind control management of an off-line prepaid card acceptance terminal may be implemented in hardware, software, firmware, or any combination thereof. The various features described are modules, units, or components that may be implemented together in an integrated logic device or separately as discrete but interoperable logic devices or other hardware devices. In some cases, various features of the electronic circuit may be implemented as one or more integrated circuit devices, such as an integrated circuit chip or chipset.
The off-line prepaid card acceptance terminal remote security wind control management method and system can be used as a processor or an integrated circuit device, such as an integrated circuit chip or a chipset. Alternatively or additionally, if implemented in software or firmware, the techniques may implement a data storage medium readable at least in part by a computer comprising instructions that, when executed, cause a processor to perform one or more of the methods described above. For example, a computer-readable data storage medium may store instructions such as those executed by a processor.
The code or instructions may be software and/or firmware executed by processing circuitry including one or more processors, such as one or more Digital Signal Processors (DSPs), general purpose microprocessors, application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs), or other equivalents to integrated or discrete logic circuitry. Thus, the term "processor," as used herein, may refer to any of the foregoing structure or any other structure as being better suited for implementation of the techniques described herein. Additionally, in some aspects, the functionality described in this disclosure may be provided in software modules and hardware modules.
As a preferred embodiment of the present invention, when the terminal machine reaches a preset condition without establishing communication connection with the background monitoring end, the terminal machine establishes communication connection with the background monitoring end when executing a first transaction after reaching the preset condition, and sends sign-in information to the background monitoring end; the terminal downloads transaction parameter items from a background monitoring end and stores the transaction parameter items and the transaction parameter items locally;
and if the communication connection with the background monitoring end cannot be established, stopping executing the first transaction, and stopping the terminal machine transaction operation.
That is, because the current communication state of the terminal machine cannot establish communication connection with the background monitoring end, or based on the operation of the user on the terminal machine, when the terminal machine is in an offline state and cannot establish communication connection with the background monitoring end, and the like, the terminal machine establishes communication connection with the background monitoring end when executing the first transaction after reaching the preset condition. That is, if in this case a communication connection cannot be established with the background monitor, the first transaction is stopped and the terminal transaction operation is stopped. The terminal is in a locking state, can not conduct transaction, can not conduct addition, deletion and correction of information, and can not operate the prepaid card.
That is, if the day is taken as the preset condition, the terminal machine must sign in with the background monitoring end every day and complete parameter downloading to enter the normal use interface, and if the terminal machine is not powered off every other day, the terminal machine will initiate sign in and parameter downloading at first in the first transaction. After the parameter item is downloaded to the local of the terminal, when recharging and consumption transaction are carried out, the terminal judges whether the transaction is allowed or not according to the parameter content downloaded locally, and if the parameter wind control limit is triggered, the terminal directly carries out transaction control. Meanwhile, the background monitoring terminal collects different parameter items and sets the parameter items into a plurality of parameter versions, so that each terminal machine can be flexibly configured and controlled to adapt to a specific parameter version.
The transaction parameters include but are not limited to,
as the transaction parameter items, a plurality of items may be set at the same time.
As the background monitoring terminal, the invention can provide a preset condition operation port, a transaction parameter item operation port, the addition, deletion and correction of transaction parameters, the addition, deletion and correction of state parameters of each terminal machine and the addition, deletion and correction of state parameters of the background monitoring terminal for users.

in an offline state, judging whether the transaction is allowed or not according to the currently downloaded transaction parameter item;
and in a normal communication connection state, sending transaction process information to the background monitoring end 1 in real time, and completing the transaction process after verification based on the background monitoring end 1.
Receiving a communication connection request sent by a terminal machine 2 when a background monitoring end 1 reaches a preset condition; or a communication connection control instruction sent to the terminal machine when a preset condition is met; establishing communication connection with a terminal;
the background monitoring terminal 1 receives sign-in information sent by establishing communication connection and sends transaction parameter items to the terminal;
the background monitoring terminal 1 receives the transaction process information of the terminal machine and verifies the transaction process information under the normal communication connection state with the terminal machine 2, and sends the verification information to the terminal machine.
