Detailed ways

The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It can be understood that the specific embodiments described here are only used to explain the relevant invention, but not to limit the invention. It should also be noted that, for convenience of description, only the parts related to the invention are shown in the drawings.

It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

The first and second numbers are only distinguished and have no other meaning.

Figure 1 is a schematic flowchart of a security control method for senseless payment provided by Embodiment 1 of the present invention. This method is used in gas station refueling scenarios. The execution subject of this method is a Point of Sale (POS) system server with calculation and processing functions. As shown in Figure 1, the method includes the following steps:

Step 101: Receive a refueling request message; wherein the refueling request message includes tag ID, target user account information, gas station ID, and fuel nozzle ID.

The gas station ID can be the number of the gas station, and each gas station has a unique number. For example, the gas station number could be "1110".

The oil gun ID can include the number of the oil gun. The oil gun can be divided into oil guns with different numbers according to the corresponding gasoline models. For example, 001 can correspond to No. 92 gasoline, and 002 can correspond to No. 95 gasoline. On each refueling equipment, you can There are one or more oil guns. When there are multiple oil guns, these oil guns can correspond to the same type of gasoline or different types of gasoline. The structure of the oil gun ID can be the gas station ID + the oil gun number + the oil gun number. For example, the meaning of "1110012001" can be: the gas station number "1110", the oil gun number "012", and the oil gun number "001". Therefore, You can use the oil gun ID to get which oil gun is under which refueling equipment under the gas station where you are located.

In this application, the received refueling request message may be sent by the card reading device on the oil gun or by the refueling equipment. There are communication modules and processing modules in the refueling equipment. The communication module in the refueling equipment can transmit data with the POS system server and oil gun.

When the refueling request message is sent by the card reading device on the oil gun, the oil gun of the gas station is equipped with a card reading device. The card reading device includes a card reader, a communication module and a memory. The memory can store the gas station ID and the oil gun. ID. The card reader can read the tag on the vehicle's fuel tank cap and decode it to obtain the tag ID. The communication module in the oil gun can package the tag ID, the gas station ID in the memory and the oil gun ID to generate a refueling request message. , sent to the POS system server.

When the refueling request message is sent by the card reading device on the oil gun, the oil gun at the gas station is equipped with a card reading device. The card reading device includes a card reader and a communication module. The card reader can read the fuel tank cap of the vehicle. After decoding the tag, the tag ID is obtained. The communication module in the oil gun can send the tag ID to the communication module in the refueling equipment. The processing module on the refueling equipment packages the gas station ID, oil gun ID and tag ID. The generated refueling request message is sent to the POS system server.

The tag may be a radio frequency identification (Radio Frequency Identification, RFID) tag.

Step 102: According to the tag ID, query the preset tag ID and user account information comparison table to obtain the target user account information corresponding to the tag ID;

Specifically, a tag ID can correspond to a piece of vehicle information, and the vehicle information includes vehicle identification (Identitydocument, ID) and vehicle model information. The vehicle ID is a unique identification of the vehicle, which can be a license plate number or a globally unique number of the vehicle.

A tag ID corresponds to one vehicle information, and a user can have one or more vehicles, that is, a user can have one tag ID or multiple tag IDs, but a user only corresponds to one user account information. Therefore, when the POS system server receives the refueling request message, it unpacks the refueling request message, determines the user account information corresponding to the tag ID based on the tag ID, and uses the user account information corresponding to the current tag ID as the target user account. information.

The user account information may be the user's Tuanyou APP account number stored in the POS system server. The Tuanyou APP here is an application used for drivers to perform refueling transactions.

Step 103: Query whether there is pre-refueling order information to be paid corresponding to the gas station ID, fuel nozzle ID and target user account information.

Among them, the pre-refueling order information to be paid includes the ID of the gas station for pre-refueling, the ID of the oil gun for pre-refueling, the number of liters of pre-refueling and the consumption amount of pre-refueling.

Specifically, the POS system server may pre-store pre-refueling order information to be paid that is pre-established by the user. The user can create pre-refueling order information by performing input operations on the user terminal. When the pre-refueling order information passes the verification of credit ability and payment ability, pre-refueling order information to be paid can be generated, and the user terminal can transfer the pre-refueling order information to be paid. The paid pre-fuel order information is sent to the POS system server. Therefore, after entering the gas station, you can directly refuel when there is pre-refueling order information to be paid.

Therefore, before step 103, this application may also include the following steps:

Receive pre-refueling order information sent by the user terminal; the pre-refueling order information includes the user ID, the ID of the gas station for pre-refueling, the ID of the oil gun for pre-refueling, the number of liters of pre-refueling and the consumption amount of pre-refueling;

According to the user ID, query the credit capability information of the user account information corresponding to the user ID; the credit capability information includes the user's credit score;

When the credit score is not less than the preset score threshold, query the first payment ability information of the user's payment account corresponding to the user account information;

When the first payment ability information is not less than the pre-fuel consumption amount, pre-fuel order information to be paid is generated.

Among them, the credit ability information can be the score of the user's credit ability. For example, the credit ability score can be generated based on the user's payment record and the customer's credit record. For example, the number of payments, total amount, etc. in the POS system server can generate a credit score, and the user's credit record in the bank can generate a credit score. After the weighted sum of the two credit scores, the user's credit ability can be obtained. information. This credit ability information is dynamically changing data and can change with the user's payment record and credit record.

Therefore, after receiving the refueling request message, the POS system server first performs a query to determine whether there is pre-refueling order information to be paid.

Step 104: When there is pre-refueling order information to be paid corresponding to the gas station ID and fuel nozzle ID in the target user's account information, a first confirmation message is generated; the first confirmation message includes the number of liters of pre-refueling.

In one example, if there is pre-refueling order information to be paid, a first confirmation message can be generated based on the number of pre-refueling liters in the pre-refueling order information to be paid, and the first confirmation message can be sent to the refueling equipment.

In another example, when there is no pre-refueling order information to be paid corresponding to the gas station ID and the oil gun ID, query the credit capability information of the user ID corresponding to the target user account information according to the target user account information; credit capability Information includes a user’s credit score;

When the credit score is not less than the preset score threshold, query the second payment ability information of the user's payment account corresponding to the target user's account information;

When the second payment ability information is not less than the preset threshold, generate a second confirmation message;

Send a second confirmation message to the refueling equipment, and the second confirmation message is used to notify the refueling equipment to perform refueling;

When the refueling is completed, receive the refueling order information to be paid from the refueling equipment; where the refueling order information to be paid is generated by the refueling equipment based on the gas station ID, the oil gun ID, the current refueling liters and the current consumption amount;

Send the refueling order information to be paid to the third-party server so that the third-party server can perform password-free payment.

In this case, subsequent calculation of the current fuel liters is required. As an example, but not a limitation, the refueling equipment can calculate the amount of refueling based on the current refueling liters and the oil gun ID, thereby generating refueling order information to be paid and sending it to a third-party server.

Therefore, when there is no pre-refueling order information to be paid, the refueling order information to be paid can be generated in real time through the refueling equipment, and password-free payment can be completed, thereby saving refueling time.

Further, when the first payment ability information is not less than the pre-fuel consumption amount, or when the second payment ability information is not less than a preset threshold, the application also includes: generating the first payment ability information Or the second payment ability information is passed through the voucher message, and the voucher message is displayed. Therefore, according to the voucher message, there is no need to verify the payment ability for a period of time, thereby improving the speed of the next payment.

Step 105: Send the first confirmation message to the refueling equipment to instruct the refueling equipment to refuel according to the pre-refueling liters.

When the refueling equipment receives the pre-refueling liters, it can control the oil gun to refuel according to the corresponding oil gun ID.

Step 106: Receive the refueling completion message sent by the refueling equipment.

The refueling completion message may also include the refueling completion time.

When refueling is completed, the refueling equipment can send a refueling completion message to the POS system server, so that the POS system server can determine that refueling is completed based on the refueling completion message.

Step 107: The pre-fuel order information to be paid is encrypted using the first symmetric key to obtain first encrypted data.

Among them, the first symmetric key here is the key when performing symmetric encryption. The first symmetric key can be generated according to a symmetric encryption algorithm. The symmetric encryption algorithm includes but is not limited to data encryption algorithm (Data Encryption Algorithm, DES), triple data Encryption algorithm (Triple Data Encryption Algorithm, 3DES), Advanced Encryption Standard (Advanced Encryption Standard, AES) algorithm, RC-5 algorithm, International Data Encryption Algorithm (IDEA).

Before step 107, security verification between the POS system and the third-party server is also required. Before performing security verification, the security of the public and private keys generated by the POS system needs to be confirmed through the server of a third-party certification agency. Public key security can be verified through the following methods:

Send the first public key, the server ID of the third-party certification authority and the third-party server ID to the server of the third-party certification authority;

The server of the third-party certification agency encrypts the first public key through the preset private key, and obtains the first public key encrypted by the server of the third-party certification agency;

The server of the third-party certification agency sends the first public key encrypted by the server of the third-party certification agency to the third-party server based on the third-party server ID;

The third-party server decrypts the encrypted first public key through the preset public key to obtain the first public key; the preset public key is the preset public key of the server of the third-party certification authority.

Among them, the server of the third-party certification authority will previously send the first public key to the POS system and the third-party server. This ensures the security of the public key through the server of the third-party certification agency, thus ensuring the security of the payment process.

The steps for security verification of the private key are the same as the steps for security verification of the public key above, and will not be described again here.

Before step 107, the POS system server will generate multiple pairs of public keys and private keys for data encryption.

Step 108: Extract the summary of the pre-fuel order information to be paid, and obtain the summary of the pre-fuel order information to be paid.

Specifically, the digest of the pre-fuel order information to be paid can be extracted through a digest algorithm, such as a message digest algorithm (MD5 Message-Digest Algorithm, MD5, Secure Hash Algorithm, SHA), etc.

Step 109: Sign the digest with the first private key to obtain the signed digest;

Specifically, the POS system server previously generated multiple pairs of public keys and private keys for asymmetric encryption. The private key can be used to digitally sign the digest, so that after decryption by a third-party server, it can be verified whether the encrypted data has been tampered with. Among them, the first private key corresponds to the subsequent first public key.

Step 110: Encrypt the first symmetric key with the second public key to obtain the encrypted first symmetric key;

Specifically, the first symmetric key for symmetric encryption can be encrypted using the second public key, thereby performing asymmetric encryption on the first symmetric key. The second public key here corresponds to the second private key later.

Step 111: Pack the first encrypted data, the signed digest and the encrypted first symmetric key to obtain encrypted data;

Specifically, after packaging the first encrypted data, the signed digest and the encrypted first symmetric key, an encrypted data is obtained, and the encrypted data is a data packet.

Step 112: Send the encrypted data to the third-party server so that the third-party server can perform password-free payment.

Among them, after the encrypted data is sent to the third-party server in the form of a data packet, the third-party server can make secret-free payment according to the preset secret-free payment agreement after decryption.

Among them, the third-party server can be a server of the payment system. For example, the specific type of server of the third-party server can be determined based on the payment method selected by the user in the pre-fuel order information to be paid. When the payment method is Alipay or When paying with WeChat, the third-party server can be Alipay or WeChat server. When the payment method is debit card payment, the third-party server can be the settlement server of the bank corresponding to the debit card. As a result, the order data is symmetrically encrypted using the first symmetric secret key, the summary is asymmetrically encrypted using the first private key, and then the first symmetric secret key is asymmetrically encrypted using the second public key, thereby ensuring that the Data security under multiple encryption.

Further, the third-party server decrypts to ensure the security of the payment. The steps for the third-party server to decrypt are as follows:

The third-party server unpacks the encrypted data and obtains the first encrypted data, the signed digest and the encrypted first symmetric key;

Decrypt the encrypted first symmetric key using the second private key to obtain the first symmetric key;

Decrypt the first encrypted data using the first symmetric key to obtain the pre-fuel order information to be paid;

Extract the summary of the pre-fuel order information to be paid through the summary algorithm to obtain the summary to be compared;

Decrypt the signed digest through the first public key to obtain the digest;

Compare the summary with the summary to be compared. When the two are equal, it is determined that the security verification is passed.

Thus, corresponding to the encryption process, the third-party server performs decryption, thereby ensuring the security of the payment process.

Similarly, the refueling order information to be paid will also be encrypted according to the above method, thereby ensuring the security of the payment process. The specific encryption method is the same as the above method for encrypting the pre-refueling order information to be paid, which is not specified here. Again.

By applying the security verification method of non-inductive payment provided by the embodiment of the present invention, the user can pre-establish the pre-fuel order information to be paid, and when the collected tags are parsed and match the pre-fuel order information to be paid, the user can directly Carry out refueling, and after the refueling is completed, after the pre-refueling order to be paid is encrypted, the password-free payment is performed, which ensures the security of the payment process, saves payment time, and avoids waiting in line for payment after the refueling is completed. Improved refueling efficiency.
