Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
The DESFire card is a virtual card that can be implemented in a cell phone, and the card specification of the DESFire card is defined by the encarpium company. DESFire cards are commonly used in the public transportation and retail areas to store the user's funds data in the card for riding or shopping by swipe transactions.
The security module (eSE; embedded Secure Element) in the mobile phone is an embedded security chip, which is internally provided with a Java Card OS to support the downloading and running of the application. When the application is programmed, the method can call the appointed API to actively send the appointed data to the mobile phone operating system when the application is operated under a certain condition, thereby achieving the purpose of informing the operating system of related information. At present, the bus Card application on the domestic mobile phone is Java application developed by a software development company based on Java Card OS, and can send transaction related information to a mobile phone operating system in the process of Card swiping transaction, so that information such as transaction amount of a user is actively prompted.
The Java Card application used by the domestic mobile phone bus Card is compiled by an intelligent Card application development company, and when a Card swiping terminal initiates recharging or consumption transaction, the information such as transaction amount and balance after the transaction is actively notified to a mobile phone operating system, so that the information can be actively displayed to a user. The domestic bus card application specification defines the instructions and flow of recharging and consuming, and the bus card application is customized and developed according to the specification requirements, so that the transaction information notification can be easily realized.
The bus Card based on the DESFire Card specification is preset in the OS when the Java Card OS manufacturer leaves the factory, and the DESFire Card is a universal data storage system, the self data read-write logic of the DESFire Card cannot correspond to the recharging or consumption transaction type, and the Java Card OS manufacturer cannot customize transaction event notification logic according to the bus Card specification of a certain country/region. Thus, the DESFire card does not accurately indicate the type of transaction that occurred and the information associated with the transaction when the transaction occurred. Fig. 1 is a schematic diagram of the structure of a DESFire card. As shown in fig. 1, the number of application directories of the DESFire card and files thereunder can be changed, the files also distinguish various types, and the number of keys stored in the key files can be changed. Thus, there may be a great difference between countries/regions when data is stored using the DESFire card.
Based on the above, the present invention provides a transaction reminding method to solve the above problems.
Examples
FIG. 2 is a flow chart of a transaction reminding method according to an embodiment of the invention.
The transaction reminding method of the embodiment is applied to the DESFire card. As shown in fig. 2, the transaction reminding method of the present embodiment may include the following steps:
s11, acquiring a transaction instruction.
In this step, a transaction instruction may be obtained. In general, when a user contacts a card swiping terminal with a use terminal provided with a desfiire card, a card swiping action is realized, and the card swiping terminal generates and transmits a transaction instruction to the desfiire card in the use terminal.
In some alternative embodiments, the user terminal may be a terminal device such as a mobile phone or a tablet computer, which is not limited in this embodiment.
In some alternative embodiments, the card swiping terminal may be a terminal device such as a card swiping machine, a card reader, etc., which is not limited in this embodiment.
In this embodiment, the transaction instruction may be obtained.
In some alternative embodiments, the transaction instructions may include data manipulation instructions, application selection instructions, and data update instructions.
In some alternative embodiments, the data manipulation instructions comprise data read instructions and data write instructions, the data read instructions comprising at least one of read data instructions, read value instructions, and read record instructions; the data write instruction includes at least one of a write data instruction, a value-added instruction, a value-subtracted instruction, and a write record instruction.
Specifically, the DESFire card defines several file types:
1)Standard Data Files
2)Backup Data Files
3)Value Files with Backup
4)Linear Record Files with Backup
5)Cyclic Record Files with Backup
wherein, for both file types Standard Data Files and Backup Data Files, read data, write data instruction operations can be used; for Value Files with Backup, a read value, a value-added value, and a value-subtracted instruction operation may be used; for both types Linear Record Files with Backup and Cyclic Record Files with Backup, a read record, write record instruction operation may be used.
In a specific application scenario, standard Data Files and Backup Data Files can store a lot of data, the content of the data can be freely defined by an application manufacturer, and the analysis rule is realized by a card reader end. Value Files with Backup stores the value of the available add-subtract, typically storing balance information. Cyclic Record Files with Backup and Cyclic Record Files with Backup are used for recording history information or fixed-length recorded information, and the content format is customized by the application manufacturer and analyzed by the card reading terminal. The file types mentioned above may be implemented in several ways according to the data plan of the application manufacturer.
In some alternative embodiments, the currently operating application is validated by an application selection instruction.
In some alternative embodiments, the data update instruction (Commit Transaction) means that updated data for the write operation is committed to be validated. Therefore, successful execution of this command means successful transaction.
S12, judging whether the triggering condition carried by the transaction instruction meets the preset triggering condition.
In this embodiment, the DESFire card is configured in advance, so that the DESFire card supports a preset trigger condition. The preset triggering conditions may include the following elements:
first, instruction type: namely an application selection instruction, a data reading instruction, a data writing instruction or a data updating instruction; second, the instruction operation target file number: specific files under a certain application are specified, and the element of the instruction operation target file number only exists when the data operation instruction type is specified; third, the instruction operates the initial offset and minimum data length of the target file: the element of the start offset and the minimum data length of the instruction manipulation object file also exists only when the data manipulation instruction type is satisfied when the data fragment specified by these two parameters is contained within the target range of the data manipulation instruction; fourth, application name: this element exists only when an application instruction is selected.
The above elements constitute a set of trigger conditions. In some alternative embodiments, multiple sets of trigger conditions may be configured for the DESFire card to trigger when different applications and files are operated in different scenarios.
Based on this, in some alternative embodiments, if the transaction instructions include application selection instructions; judging whether the triggering condition carried by the transaction instruction meets the preset triggering condition or not comprises the following steps:
judging whether the triggering condition carried by the application selection instruction comprises an application name or not, and if the triggering condition carried by the application selection instruction comprises the application name, indicating that the triggering condition carried by the application selection instruction meets the preset triggering condition.
In some alternative embodiments, if the transaction instructions include data manipulation instructions; judging whether the triggering condition carried by the transaction instruction meets the preset triggering condition or not comprises the following steps:
judging whether a triggering condition carried by the data operation instruction comprises instruction operation information or not; the instruction operation information comprises an instruction operation target file number, a starting offset of the instruction operation target file and a minimum data length;
if the trigger condition carried by the data operation instruction comprises instruction operation information, judging whether the initial offset and the minimum data length of the instruction operation target file are contained in the target range of the data operation instruction;
if the initial offset and the minimum data length of the instruction operation target file are contained in the target range of the data operation instruction, the trigger condition carried by the data operation instruction is indicated to meet the preset trigger condition.
In some alternative embodiments, the predetermined trigger condition is satisfied if the transaction instruction includes a data update instruction.
And S13, if the triggering condition carried by the transaction instruction meets the preset triggering condition, judging whether the data configuration to be transmitted corresponding to the transaction instruction exists.
Each set of trigger conditions also corresponds to 0-n sets of data configuration to be transmitted. In some optional embodiments, if the trigger condition carried by the transaction instruction meets the preset trigger condition, it may further be determined whether there is a data configuration to be sent corresponding to the transaction instruction.
The configuration of the data to be transmitted is also input into the DESFire card in advance.
S14, if the data configuration to be transmitted corresponding to the transaction instruction exists, generating transaction reminding information according to the data configuration to be transmitted.
The data configuration to be transmitted of the data to be transmitted includes the following elements: the number of the target file, and the starting offset and data length of the target file. The target file number designates a specific file under a certain application; the starting offset and data length of the destination file specify the source and length of the data to be sent.
In some alternative embodiments, if there is a data configuration to be sent corresponding to the transaction instruction, reading data parameters according to the data configuration to be sent;
and processing the data parameters according to a preset format, and taking the processed data parameters and the triggering conditions carried by the transaction instruction as transaction reminding information.
Specifically, when the transaction reminding information is sent, the sent data content comprises the triggering condition carried by the transaction instruction and the processed data parameter. The triggering condition carried by the transaction instruction can help the application software on the terminal to judge the type of the currently executed service; the processed data parameters may then help determine specific transaction information for the service type. If the trigger condition carried by the transaction instruction matches one or more groups of data parameters, when the trigger condition is satisfied, all data to be transmitted are read according to a stipulated format and then assembled and transmitted.
In some alternative embodiments, if there is no data configuration to be sent corresponding to the transaction instruction, generating transaction reminding information according to the type of the transaction instruction.
Specifically, if the trigger condition carried by the transaction instruction does not match the data parameter, only a basic notification is sent and no designated data is sent when the trigger condition is satisfied.
S15, sending the transaction reminding information to the using terminal.
In this step, the transaction reminding information may be sent to the operating system of the user terminal through a transaction event notification interface provided by the Java Card OS.
It should be noted that, each set of trigger conditions also corresponds to a transmission opportunity configuration of a transaction event. The configuration defines a point in time when the transaction event is sent when the trigger condition is met. The transmission opportunity optional case includes: immediate transmission, transmission when the "submit data update" instruction is executed successfully, and/or transmission when the card leaves the field (away from the reader field area).
If the preset sending configuration is immediately sent or the sending configuration information is not detected, the transaction reminding information can be sent to the operating system of the using terminal through a transaction event notification interface provided by the Java Card OS immediately after the triggering condition is met; if the preset sending configuration is that the transaction reminding information is sent according to the data updating instruction and/or the Card departure information, the transaction reminding information can be cached first, and after the data updating instruction and/or the Card departure information is detected, the transaction reminding information is sent to the operating system of the using terminal through a transaction event notification interface provided by the Java Card OS.
The transaction reminding method comprises the steps of obtaining a transaction instruction; judging whether a triggering condition carried by a transaction instruction meets a preset triggering condition or not; if the triggering condition carried by the transaction instruction meets the preset triggering condition, determining the data configuration to be transmitted corresponding to the transaction instruction; determining transaction reminding information according to the data configuration to be sent; and sending the transaction reminding information to the using terminal so that the using terminal outputs the transaction reminding information. The invention presets the trigger condition and the data to be sent into the DESFire card application, can achieve the effect of accurately informing the transaction type and the transaction information by analyzing and judging the trigger condition carried by the transaction instruction, meets the requirement of transaction event notification in the transaction process carried out by the DESFire card, and the modification of the DESFire card application is fixed without changing according to different countries/regions, and only needs to change the trigger condition and the configuration of the data to be sent.
In some alternative embodiments, prior to obtaining the transaction instructions, the method further comprises the steps of:
and acquiring and storing preset trigger conditions, data configuration to be transmitted and preset transmission configuration to realize the configuration of the DESFire card.
The preset trigger condition, the data configuration to be sent and the preset sending configuration need to be configured into the DESFire card application before the user can swipe the card, so that the data configuration to be sent can be sent to the mobile phone operating system according to the related parameters when the DESFire card application is executed.
In this embodiment, the virtual bus card is taken as an example to further describe this step.
After the user selects to open the virtual bus card and pay the related fee, the user terminal for installing the DESFire card initiates an application to the server, acquires the script of creating the virtual bus card and writing the data and operates the script. The script can be implemented to create a blank DESFire card application in the eSE and write the user's card data into the DESFire card application. And after the data writing is completed, the card is successfully downloaded (opened), and the user can swipe the card for use. The preset trigger condition and the writing of parameters such as data configuration to be sent can be completed together with the installation process of the DESFire card application or together with the card data writing process of the DESFire card application.
In summary, before acquiring the transaction command, the method mainly comprises the following two steps: firstly, reforming a DESFire card application to support a transaction event triggering condition, and configuring and analyzing data to be transmitted and sending the transaction event; and secondly, when the DESFire card application is initialized in the eSE, or after the initialization of the DESFire card application, configuring preset triggering conditions, data configuration to be transmitted and preset transmission configuration before use.
