[0073] In order to make the structure and advantages of the present invention more clear, the structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0074] Embodiment 1

[0075] The main execution ideas of this application processing method are:

[0076] During the deposit process, the chip counter mechanism in the non-stop toll collection card is combined to conduct a security check on the entire deposit process to ensure that each recharge can only be deposited once. And if the deposit process on the user's mobile phone APP fails, the previous abnormal record can be automatically processed during the next operation.

[0077] Specifically, the security verification method for the fee data loading process proposed in the embodiment of the present application is as follows: Figure 1 As shown, including:

[0078] S1, extracting the deposit feature value in the deposit terminal;

[0079] S2, sending a loading application to a loading server based on the obtained loading feature value and the loading count value;

[0080] S3: If a successful return value of the deposit application is received from the server, the deposit operation is completed according to the successful return value of the deposit application;

[0081] S4: If the successful return value of the deposit application is not received from the server, a deposit exception is raised.

[0082] In practice, in order to solve the possible repeated loading behavior, the embodiment of the present application proposes that the loading characteristic value is based on the common data type in the common terminal transaction record file, and there is no need to modify the existing file.

[0083] The entire deposit process including the above content is as follows:

[0084] After starting to load, execute the load initialization command.

[0085] If the command is executed successfully, the initialization is judged to be successful, and the CPU card is controlled to return the initialization result information. On the contrary, if the command fails to be executed, the rollover is judged to be failed.

[0086] Then parse the initialization information of the deposit, assemble the information and call the encryption machine interface of the remote deposit server.

[0087] If the encryption machine of the credit server returns MAC2, the credit instruction is further executed; if the encryption machine does not return a message, it is determined that the credit fails.

[0088] After executing the transfer instruction, the CPU card returns the transfer result information.

[0089] After executing the Get Balance command, get the balance after the transfer, and determine whether the current balance is equal to the sum of the amount before the transfer and the transfer amount.

[0090] If they are equal, the deposit is determined to be successful, otherwise it is determined to be a failure.

[0091] In the above process, perform the following steps:

[0092] Specifically, the step of obtaining the feature value of the deposit, i.e., S1, includes:

[0093] S11, obtaining the transaction record file in the loading terminal;

[0094] S12, extracting the online transaction sequence number and the amount of the deposit that are closest to the current time from the transaction record file;

[0095] S13, if the obtained online transaction serial number and the top-up amount are consistent with the values ​​stored in the top-up server, it is determined that a top-up feature value meeting the requirements has been extracted;

[0096] S14, if the obtained online transaction sequence number and the deposit amount are inconsistent with the values ​​stored in the deposit server, the deposit feature value is determined to be an abnormal value.

[0097] In practice, the online transaction number (LastCounter) of the most recent deposit record in the card is represented by C, the deposit amount (LastMoney) of the most recent deposit record in the card is represented by M, and the card counter (Counter) that automatically increases by 1 each time a deposit is successful is represented by S.

[0098] When it is necessary to obtain C and M in the above-mentioned recharge characteristic values, the transaction record file in the card is read, and then the first matching recharge record is found through the transaction terminal number to obtain it.

[0099] Since the above data are important data representing the process of depositing, it is necessary to judge whether there is any abnormality in the depositing process based on the specific values ​​of the above data types. If the data value cannot be obtained, it means that there may be no deposit record, and a second judgment is required based on the deposit record query result, as follows:

[0100] S141, querying the current card's transfer record in the transfer record table;

[0101] S142: if the deposit record cannot be found, a deposit exception is reported;

[0102] S143: If a loading record is found, the loading record of the loading service is adjusted, and a loading confirmation process is performed based on the adjusted loading record.

[0103] If no top-up record is found and the top-up server has no top-up record, it means that there was no top-up operation before and it is normal. However, if the top-up record is found, the top-up record of the top-up server needs to be adjusted so that the top-up can continue, including:

[0104] S1431, calculating the difference between the loading count value and the loading count value in the loading record;

[0105] S1432, if the difference is greater than or equal to the loading record threshold set in the loading terminal, terminate the current loading operation;

[0106] S1433: If the difference is less than the loading record threshold set in the loading terminal, the loading count value in the obtained loading record is increased by one, and the obtained loading record is saved to the loading server, and the loading operation is completed in the loading terminal.

[0107] Optionally, S2 includes:

[0108] S21, sending the obtained online transaction serial number, loading terminal number, loading amount and the current loading count value representing the loading amount as keywords to the loading server;

[0109] S22, the credit loading server feeds back a corresponding credit loading application return value according to the received keyword.

[0110] In practice, based on data storage and security considerations, all credit records are stored on the server, so it is necessary to send a request to the credit server to obtain the required credit records.

[0111] Based on the feedback of the deposit record, the subsequent processing process is discussed based on the deposit record to reflect whether the deposit is successful and whether it is the latest deposit record. It mainly includes the following contents:

[0112] S31: If it is determined that the current loading record is the latest and completed loading operation, it is determined that the loading operation has been completed.

[0113] S32: If it is determined that the current storage record is not a completed storage operation, it is determined whether the current storage record is the latest storage record.

[0114] At this time, the secondary determination based on whether it is the latest deposit record is as follows:

[0115] S321: If it is determined that the current loading record is the latest loading record, the loading confirmation interface of the business system is called to complete the loading operation.

[0116] S322: If it is not the latest deposit record, a deposit exception is raised.

[0117] S33: If it is determined that the current loading record belongs to a loaded operation but is not the latest loading record, the loading confirmation is completed again at the loading terminal, and the loading operation is completed according to the confirmation result.

[0128] Then parse the initialization information of the deposit, assemble the information and call the encryption machine interface of the remote deposit server.

[0129] If the encryption machine of the credit server returns MAC2, the credit instruction is further executed; if the encryption machine does not return a message, it is determined that the credit fails.

[0130] After executing the transfer instruction, the CPU card returns the transfer result information.

[0131] After executing the Get Balance command, get the balance after the transfer, and determine whether the current balance is equal to the sum of the amount before the transfer and the transfer amount.

[0137] The second result determination subunit 214 is used to determine that the loading feature value is an abnormal value if the obtained online transaction sequence number and the loading amount are inconsistent with those stored in the loading server.

[0138] In practice, the online transaction number (LastCounter) of the most recent deposit record in the card is represented by C, the deposit amount (LastMoney) of the most recent deposit record in the card is represented by M, and the card counter (Counter) that automatically increases by 1 each time a deposit is successful is represented by S.

[0139] When it is necessary to obtain C and M in the above-mentioned recharge characteristic values, the transaction record file in the card is read, and then the first matching recharge record is found through the transaction terminal number to obtain it.

[0140] Since the above data are important data representing the process of depositing, it is necessary to judge whether there is any abnormality in the depositing process based on the specific values ​​of the above data types. If the data value cannot be obtained, it means that there may be no deposit record, and a second judgment is required based on the deposit record query result, as follows:

[0144] The second processing sub-unit 213 is configured to adjust the loading record of the loading server if a loading record is found, and perform loading confirmation processing based on the adjusted loading record.

[0145] If no top-up record is found and the top-up server has no top-up record, it means that there was no top-up operation before and it is normal. However, if the top-up record is found, the top-up record of the top-up server needs to be adjusted so that the top-up can continue, including:
