Description

Technical Field

[0001] This application belongs to the field of payment processing, and in particular relates to a method, apparatus, electronic device and computer storage medium for purchasing goods. Background Technology

[0002] Currently, self-service terminals generally use a user-initiated scanning method to sell goods. This requires network access to provide users with goods purchase services. After the user selects the desired goods on the self-service terminal, the backend service of the self-service terminal calls the corresponding payment channel to generate a payment QR code and displays it to the user, so that the user can scan the payment QR code to pay for the purchased goods through the smart terminal. Before the user completes the payment, the self-service terminal will use a polling method to query the final execution result of the transaction.

[0003] Existing self-service terminal purchasing methods rely on network services. Self-service terminals are not only limited by the network, but also require the network to be able to transmit data stably, which limits the scope of use of self-service terminals. Summary of the Invention

[0004] This application provides a method, apparatus, electronic device, and computer storage medium for purchasing goods, enabling self-service terminals to provide goods purchasing services to users without relying on network services.

[0005] In a first aspect, embodiments of this application provide a method for purchasing goods, applied to a self-service terminal, which may include:

[0006] Upon receiving the first operation, first output information associated with the target product is output, wherein the first operation is used to select the target product, and the first output information includes the identification information of the self-service terminal and the purchase information of the target product, wherein the identification information of the self-service terminal includes the public key of the self-service terminal.

[0007] The user terminal outputs second output information including a first signature. The first signature is a signature generated by the user terminal based on the first output information when it obtains the first output information and receives a payment operation. The payment operation is used to pay for the target product. The second output information is generated based on the first signature and the first output information.

[0008] The first signature in the second output information is verified using the public key of the self-service terminal to obtain the first verification result, wherein the public key of the self-service terminal is associated with the self-service terminal.

[0020] Upon receiving a payment operation, a first signature is generated based on the first output information. The first signature is a signature used by the user terminal to encrypt the first output information. The payment operation is used to pay for the target goods.

[0021] Based on the first signature and the first output information, generate the second output information;

[0022] The self-service terminal outputs second output information to itself, so that after the self-service terminal verifies the first signature in the second output information using its public key, it controls the shipment of the target product.

[0023] In one embodiment, after obtaining the first output information as described above, the process further includes:

[0024] The first output information is decrypted using the second key to obtain the identification information of the self-service terminal and the purchase information of the target product.

[0025] In one embodiment, the second key mentioned above includes a payment channel private key, and the first output information includes a first ciphertext and a second ciphertext. The first ciphertext is obtained by encrypting the first random key with the payment channel public key, and the second ciphertext is obtained by encrypting the identification information of the self-service terminal and the purchase information of the target product with the first random key.

[0081] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0082] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0083] As discussed in the background section, existing self-service machines rely on network services, which not only limits their operation but also requires a stable network connection. Furthermore, using a polling method would increase resource waste.

[0084] To address the problems existing in the prior art, embodiments of this application provide a method, apparatus, electronic device, and computer storage medium for purchasing goods. Upon receiving a first operation, a self-service terminal outputs first output information associated with a target product. Then, it acquires second output information, including a first signature, generated by a user terminal based on the first output information. The self-service terminal verifies the first signature in the second output information using its public key, obtaining a first verification result. If the first verification result indicates that the first signature verification is successful, the self-service terminal controls the shipment of the target product.

[0085] In this way, by having the user terminal generate second output information based on the received first output information, and then having the self-service terminal verify the first signature in the second output information generated by the user terminal, the self-service terminal can determine whether the user has completed the payment order and the goods the user needs to purchase simply by verifying the first signature, without relying on network services, and thus complete the shipment of goods.

[0086] This application provides a method, apparatus, electronic device, and computer storage medium for purchasing goods. The method for purchasing goods provided in this application will be described first. Figure 1 As shown in the embodiments of this application, the method for purchasing goods includes the following steps:

[0087] S101: Upon receiving the first operation, the self-service terminal outputs first output information associated with the target product, wherein the first operation is used to select the target product, and the first output information includes the identification information of the self-service terminal and the purchase information of the target product, and the identification information of the self-service terminal includes the public key of the self-service terminal.

[0088] S102: The user terminal obtains the first output information;

[0089] S103: When the user terminal receives a payment operation, it generates a first signature based on the first output information. The payment operation is used to pay for the target goods.

[0090] S104: Generate second output information based on the first signature and the first output information;

[0091] S105: The user terminal outputs second output information including a first signature to the self-service terminal. The first signature is a signature generated by the user terminal based on the first output information when it obtains the first output information and receives a payment operation. The payment operation is used to pay for the target goods. The second output information is generated based on the first signature and the first output information.

[0092] S106: The self-service terminal verifies the first signature in the second output information using the self-service terminal public key to obtain the first verification result, wherein the self-service terminal public key is associated with the self-service terminal;

[0093] S107: If the first verification result indicates that the first signature verification is successful, the self-service terminal controls the shipment of the target goods.

[0094] This application provides a method, apparatus, electronic device, and computer storage medium for purchasing goods. Upon receiving a first operation, a self-service terminal outputs first output information associated with a target product. Then, it acquires second output information, including a first signature, generated by a user terminal based on the first output information. The self-service terminal verifies the first signature in the second output information using its public key, obtaining a first verification result. If the first verification result indicates that the first signature verification is successful, the self-service terminal controls the shipment of the target product.

[0095] In this way, by having the user terminal generate second output information based on the received first output information, and then having the self-service terminal verify the first signature in the second output information generated by the user terminal, the self-service terminal can determine whether the user has completed the payment order and the goods the user needs to purchase simply by verifying the first signature, without relying on network services, and thus complete the shipment of goods.

[0096] In S101, the first operation can be that the user selects the product to be purchased on the display screen of the self-service terminal. The first output information includes, but is not limited to, output in the form of a QR code, such as a barcode, audio information, wireless transmission information, etc., which are data transmission methods that do not rely on a network, and are not limited here.

[0097] In one example, to improve the security of information transmission, upon receiving a first operation, first output information associated with the target product is output, including: upon receiving the first operation, generating a first key; encrypting the identification information of the self-service terminal and the purchase information of the target product according to the first key to obtain the first output information; and outputting the first output information associated with the target product.

[0098] In one specific embodiment, the first key includes a first random key and a payment channel public key; the identification information of the self-service terminal and the purchase information of the target product are encrypted according to the first key to obtain the first output information, including: encrypting the first random key according to the payment channel public key to obtain the first ciphertext, and encrypting the identification information of the self-service terminal and the purchase information of the target product according to the first random key to obtain the second ciphertext; and obtaining the first output information according to the first ciphertext and the second ciphertext.

[0099] The target product can be any one of multiple products offered for sale by the self-service terminal. The purchase information for the target product may include product identification information and product price, and the identification information for the self-service terminal may include the self-service terminal identifier and the self-service terminal public key. The step of obtaining the first output information based on the first ciphertext and the second ciphertext can specifically include merging the first ciphertext and the second ciphertext to generate the first output information.

[0100] In S102, in one example, the user terminal can obtain the first input information by scanning. For example, the user scans a QR code with their smartphone and transmits the obtained first output information to the backend service of the payment application.

[0101] In one example, to improve the security of information transmission, after obtaining the first output information, the method further includes: decrypting the first output information using a second key to obtain the identification information of the self-service terminal and the purchase information of the target product.

[0102] In one example, the second key includes the payment channel private key, and the first output information includes a first ciphertext and a second ciphertext. The first ciphertext is obtained by encrypting the first random key with the payment channel public key, and the second ciphertext is obtained by encrypting the identification information of the self-service terminal and the purchase information of the target product with the first random key.

[0103] The first output information is decrypted using the second key to obtain the identification information of the self-service terminal and the purchase information of the target product, including: decrypting the first ciphertext using the payment channel private key to obtain the first random key; and decrypting the second ciphertext using the first random key to obtain the identification information of the self-service terminal and the purchase information of the target product.

[0104] In S103, the payment operation can be the operation of the user confirming a payment order and completing the order payment.

[0105] In one example, upon receiving a payment operation, a first signature is generated based on the first output information, including:

[0106] Upon receiving a payment request, a second random key is generated;

[0107] The second random key is encrypted using the public key of the self-service terminal to generate the third ciphertext, and the payment order is encrypted using the second random key to generate the fourth ciphertext. The payment order is generated based on the identification information of the self-service terminal and the purchase information of the target product.

[0108] The second signature is obtained by signing the third and fourth ciphertexts using the payment channel's private key.

[0109] The second signature, third ciphertext, and fourth ciphertext are sent to the self-service terminal server so that the server can verify the second signature using the payment channel public key and obtain a second verification result. If the second verification result indicates that the second signature has been verified, the server decrypts the third ciphertext using the self-service terminal private key to obtain a second random key, and decrypts the fourth ciphertext using the second random key to obtain a payment order. A shipping instruction is generated based on the payment order, and the shipping instruction is signed using the self-service terminal private key to obtain a first signature. The first signature is then sent to the user terminal. The second verification result is used to indicate whether the second signature has been verified.

[0110] In S104, in one example, a payment voucher QR code is generated based on the shipping instruction generated from the first signature and the first output information.

[0111] In S105, in one example, the user terminal outputs second output information to the self-service terminal, for example, the user presents a payment voucher QR code to the self-service terminal.

[0112] In S106, the self-service terminal verifies the first signature using its public key to obtain a first verification result, which can be used to indicate whether the first signature has been verified.

[0113] In S107, if the verification result indicates that the first signature verification is successful, the self-service terminal completes the shipment of the goods according to the target goods corresponding to the shipment instruction.

[0114] To improve the accuracy and security of payment vouchers, such as Figure 2 As shown in the figure, this application embodiment improves a product purchase method, applied to a self-service terminal server, the method including:

[0115] S201: Receive the second signature, third ciphertext, and fourth ciphertext sent by the user terminal;

[0116] S202: Verify the second signature based on the payment channel public key to obtain a second verification result, which is used to indicate whether the second signature has been verified successfully;

[0117] S203: If the second verification result indicates that the second signature verification is successful, the third ciphertext is decrypted using the private key of the self-service terminal to obtain the second random key;

[0118] S204: Decrypt the fourth ciphertext using the second random key to obtain the payment order, which is generated based on the identification information of the self-service terminal and the purchase information of the target product;

[0119] S205: Generate a shipping instruction based on the payment order;

[0120] S206: Sign the shipping instruction using the private key of the self-service terminal to obtain the first signature;

[0121] S207: Send the first signature to the user terminal.

[0122] By sending the second signature, third ciphertext, and fourth ciphertext to the automated terminal server and verifying the second signature, and generating a shipping instruction based on the payment order and signing the shipping instruction if the verification is successful, the accuracy and security of the second output information used as a payment voucher can be improved.

[0123] In S201, the self-service terminal server receives the second signature, third ciphertext, and fourth ciphertext sent by the user terminal via the network.

[0124] In S202, the self-service terminal server verifies the second signature based on the payment channel public key and obtains the second verification result.

[0125] In S203, if the second signature is verified, the self-service terminal server decrypts the third ciphertext using the self-service terminal's private key to obtain the second random key.

[0126] In S204, the self-service terminal server decrypts the fourth ciphertext using the second random key to obtain the payment order.

[0127] In S205, the self-service terminal server generates a shipping instruction corresponding to the target product based on the payment order.

[0128] In S206, the self-service terminal server signs the delivery instruction based on the self-service terminal's private key to obtain the first signature.

[0129] In S207, the self-service terminal server sends the first signature to the user terminal via the network.

[0130] To better illustrate this application, a specific embodiment is provided below:

[0131] like Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the architecture of the product purchasing method provided in the embodiments of this application. Figure 4 This is a schematic diagram illustrating the information transmission of a product purchase method provided in an embodiment of this application.

[0132] The solution provided in this application will now be described according to several core processes in the scenario of a user purchasing goods at a self-service terminal.

[0133] 1. The user clicks on the screen to select the product they want to buy, and the self-service terminal displays a payment QR code.

[0134] In this process, when the user clicks the screen to select the product to purchase, the internal program of the self-service terminal will generate a random key M1. The random key M1 is encrypted with the payment channel public key P1 to obtain ciphertext C1. The product information (product identifier, price) and self-service terminal information (self-service terminal identifier, self-service terminal public key P2) are encrypted using the random key M1 to obtain ciphertext C2. The ciphertext C1 and ciphertext C2 are combined to generate a payment QR code.

[0135] 2. Users scan the payment QR code using the payment app and complete the payment.

[0136] After a user scans a payment QR code using the payment app, the QR code information is transmitted to the payment app's backend service. The payment app's backend service uses the payment channel private key K1 to decrypt ciphertext C1 to obtain a random key M1. It then uses the random key M1 to decrypt ciphertext C2 to obtain product information and self-service terminal information. Based on this information, a payment order is generated and returned to the user. After the user confirms the payment order and completes the payment, the payment app's backend service generates a random key M2 and encrypts it using the self-service terminal's public key P2 to generate ciphertext C3. It then encrypts the order information using the random key M2 to generate ciphertext C4. Finally, it signs ciphertext C3 and ciphertext C4 using the payment channel private key K1 to obtain signature S1. The signature S1, ciphertext C3, and ciphertext C4 are then sent to the self-service terminal's backend service. The self-service terminal's backend service verifies the signature S1 using the payment channel's public key P1. After successful verification, it decrypts the ciphertext C3 using the self-service terminal's private key K2 to obtain the random key M2. Then, it decrypts the ciphertext C4 using the random key M2 to obtain the order information. Finally, the self-service terminal's backend service signs the shipping instruction using its private key K2 to obtain signature S2, and sends it to the payment app's backend service. The payment app's backend service then generates a payment voucher QR code and returns it to the user.

[0137] 3. Self-service terminal scans user's payment voucher QR code

[0138] At this point, the user can present the payment voucher QR code to the self-service terminal. The internal program of the self-service terminal uses the self-service terminal's public key P2 to verify the signature S2. After the verification is successful, the goods are shipped according to the delivery instruction.

[0139] Based on the product purchasing method provided in the above embodiments, correspondingly, such as Figure 5 As shown in the figure, this application embodiment provides a product purchasing device 500, applied to a self-service terminal, which may include:

[0140] The output module 501 is used to output first output information associated with the target product when a first operation is received. The first operation is used to select the target product, and the first output information includes the identification information of the self-service terminal and the purchase information of the target product. The identification information of the self-service terminal includes the public key of the self-service terminal.

[0141] The acquisition module 502 is used to acquire second output information including a first signature from the user terminal. The first signature is a signature generated by the user terminal based on the first output information when it acquires the first output information and receives a payment operation. The payment operation is used to pay for the target product. The second output information is generated based on the first signature and the first output information.

[0142] The verification module 503 is used to verify the first signature in the second output information using the public key of the self-service terminal to obtain the first verification result, wherein the public key of the self-service terminal is associated with the self-service terminal.
