Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The embodiment of the invention provides a method for confirming product information, which can be applied to electronic commerce transaction platforms, such as B2B, B2C, C2C and other electronic commerce platforms; referring to fig. 1-2, the e-commerce transaction process includes at least: three links of purchasing an order (PO), sending goods (RS) and confirming receiving goods (SC); the block chain storage can be carried out on the information related to the three links of Purchasing Order (PO), sending goods (RS) and confirming receiving goods (SC), and the data can be ensured to be not falsified, complete and accurate.

Wherein: the seller 10 has a first public key 11 and a first secret key 12, and the buyer 20 has a second public key 21 and a second secret key 22, wherein the first public key 11 is the address of the seller 10 and the second public key 21 is the address of the buyer 20. For example, the buyer 20 may provide for downloading a corresponding application from an e-commerce website to generate his/her own second public key 21 and second secret key 22. The public key (public key) and the private key (PrivateKey) related to the buyer and the seller are a key pair (i.e., a public key and a private key) obtained through an algorithm, the public key is a public part of the key pair, and the private key is an unpublished part.

The method for confirming product information includes: (1) A step of sending a purchase order by a buyer and a step of confirming the purchase order by a seller;

the following two steps are described as follows:

(1) The step of sending a purchase order by the buyer:

1.1 in the process that a buyer sends a purchase order to a seller, the second public key and the serial number of a product corresponding to the purchase order are sent to the seller;

1.2, encrypting the price and the serial number of the product corresponding to the purchase order according to a second public key of the buyer to generate a first hash value;

1.3 the buyer encrypts the first hash value and the first public key through the second secret key to generate a first electronic signature;

1.4 sending the first hash value and the first electronic signature to a seller;

in a purchase order, the second public key 21 may be used to indicate who has ordered the product. Referring to fig. 2, each product 13 of the seller 10 has a serial number 131 for identifying the product 13 ordered in the purchase order on the e-commerce website, and the buyer 20 can download the serial number 131 of the product 13 to be ordered and the first public key 11 representing the seller from the website. In addition, the first public key 11 is adapted to indicate the destination address of the PO. In a PO transaction, after ordering the product, the second public key 21 and serial number 131 are sent from the buyer 20 to the seller 10, and the seller 10 can then generate a PO confirmation.

In the process of sending the purchase order, the buyer 20 can generate a first hash value 23 for the price of the product 13 to be ordered and the serial number 131 of the product 13 through the second public key 21.

In addition, referring to fig. 3, the buyer 20 may generate a first electronic signature 24 by encrypting the first hash value 23 and the first public key 11 using the second key 22. The first hash value 23 and the first electronic signature 24 are sent to the seller 10 in the transaction.

(2) Step of confirming purchase order by seller:

2.1 the seller decodes the first electronic signature through the second public key to obtain a code A1 and a code B1;

2.2 when the code A1 is the same as the first public key and the code B1 is the same as the first hash value, the purchase order is validated.

In the PO validation process, as shown with reference to fig. 4, the seller 10 decodes the first electronic signature 24 using the second public key 21 to generate the code-A1 and the code-B1; and if the code-A1 and the code-B1 are identical to the first public key 11 and the first hash value 23, respectively, the PO is confirmed and the seller 10 can obtain the information of the buyer 20. On the other hand, if the purchase order is not confirmed, an order failure occurs when the buyer 20 does not pay for the order. Therefore, the method can prevent the loss of the seller 10 caused by people wanting to place an order.

In this embodiment, the method for confirming product information includes: a step of sending a purchase order by a buyer and a step of confirming the purchase order by a seller; the method realizes the uplink storage of data of each link of related purchasing orders, goods sending and receiving confirmation through a block chain technology, and ensures that the data is not falsifiable, complete and accurate; the transaction process of transmitting a purchase order and confirming the purchase order between a buyer and a seller can be monitored, and the transaction process information is encrypted, so that the electronic commerce online transaction is more reliable and safe.

In one embodiment, the tax authority is configured to join a blockchain and the tax blocks are configured to be automatically archived to the tax authority, which may reduce any costs associated with the tax refund process.

In one embodiment, the code may relate to all of the information required by the credit card holder to pay for the order.

In one embodiment, referring to FIG. 5, after confirming the PO, the seller 10 performs the sending of the goods (RS). During actual shipment (RS), the seller 10 encrypts the first hash value 23 and the first electronic signature 24 by the first public key 11, and generates the second hash value 15. Further, the seller 10 generates a second electronic signature 14 by encrypting the second hash value 15 with the first key 12.

In one embodiment, in the step of transmitting the goods performed by the seller, the steps of encrypting and decrypting a Radio Frequency Identification (RFID) tag are further included; the RFID technology, also called radio frequency identification, is a communication technology, and can identify a specific target through a radio signal and read and write related data without establishing mechanical or optical contact between an identification system and the specific target; RFID may be used for security traceability, such as attaching certain radio frequency tags to clothing, cargo packages, and the like.

Referring to fig. 5 and 6, the encryption step of the RFID tag includes: encrypting the second hash value 15 by the second public key 21 generates RFID-a161, while encrypting the second electronic signature 14 by the second public key 21 generates RFID-b162. The RFID-b162 and the RFID-a161 are used for attaching to goods or goods, respectively; can be used for tracking and verifying the identity and source of the product.

Such as attaching or sealing the RFID-a161 and RFID-b162 to the product 13 in the package 17 from which the buyer 20 purchased the goods. Taking product 13 as wine for example, RFID-a161 may be attached to wine bottle 16, while RFID-b162 may be embedded in the cork of bottle 16 by being covered by a film. Thus, if the RFID-a161 is damaged or removed from the bottle 16, the purchaser 20 can readily know that a similar collision or other abnormal event may have occurred during the transportation. Similarly, if RFID-b162 is damaged, it may indicate that wine may have been opened during shipment.

In one embodiment, the RFID-a161 may also be disposed in the bottle 16. In addition, the RFID-a161 and the RFID-b162 may also be subjected to temperature changes, humidity changes, and the like, such as the external environment. Therefore, by using the RFID-a161 and the RFID-b162, the purchaser 20 can easily recognize whether the purchased product 13 is the product he/she actually ordered.

During actual shipping, a bad vendor may attempt to copy data from RFID-a161 to another counterfeit RFID tag attached to another bottle. To address this issue, however, only the buyer 20 can confirm the shipment since the second key 22 is essential to decrypt the data stored in the RFID-b162. Further, a Physically Unclonable Function (PUF) or a copy prevention function is assumed in the RFID attached to or packaged in the product 13. Also, the seller 10 may additionally transmit the second hash value 15 to the buyer 20 separately without through the RS flow.

In one embodiment, the seller 10 generates the second electronic signature 14 by encrypting the second public key 21 and the second hash value 15 with the first key 12.

In another embodiment, each of RFID-a161 and RFID-b162 may have functionality for detecting environmental changes during transit. Such as either or both of RFID-a161 and RFID-b162, may facilitate more accurate measurement of changes in the ambient temperature of the cargo during transport by using an RFID active electronic tag that includes, for example, a tag temperature sensor.

Referring to fig. 7 and 8, the step of decrypting the RFID tag includes: there are at least two ways for the buyer 20 to confirm the receipt of the product 13. For the first method, the buyer 20 can decode the data stored in the RFID-B162 using the second key 22 to obtain the second electronic signature 14, and then the buyer 20 decodes the second electronic signature 14 using the first public key 11 to obtain the code B2. And if the code B2 is the same as the second hash value 15, confirming that the information of the goods to be loaded is correct.

For the second method, the purchaser 20 needs to additionally decode the RFID-a161 with the second key 22 to obtain the code C2, compared to the first method, and only when the purchaser 20 and the seller 10 are correct, both the code C2 and the code B2 are identical to the second hash value 15. That is, when either the code C2 or the code B2 is different from the second hash value 15, the buyer 20 cannot confirm that the information of the shipment is correct. If the information of the goods to be shipped is confirmed to be correct by the buyer 20, the buyer 20 can believe that the shipped products 13 are the same as he/she ordered. Otherwise, the product 13 may be subjected to certain operations (e.g., replacement, damage) during the shipping process. In actual shipping, RFID-a161 may be located remotely from RFID-b162 to prevent both RFID tags from being destroyed at the same time.

In one embodiment, the final transaction between seller 10 and buyer 20 is a confirmed receipt (SC) link for buyer 20. Referring to FIG. 9, after successfully receiving the product 13, the buyer 20 may send the SC to the seller 10. In the process of confirming the receipt (SC), the buyer 20 may encrypt the second hash value 15 and the second electronic signature 14 by the second public key 21 to generate a third hash value 25, and then the buyer 20 generates a third electronic signature 26 by encrypting the first public key 11 and the third hash value 25 by the second secret key 22. Thereafter, the buyer 20 sends the third electronic signature 26 and the third hash value 25 to the seller 10. Referring to fig. 10, the final step of the SC process is that the seller 10 checks shipment confirmation by decoding the third electronic signature 26 with the second public key 21, thereby generating a code A3 and a code B3, and confirms that shipment is completed if the code A3 and the code B3 are identical to the first public key 11 and the third hash value 25, respectively.

Compared with the traditional online transaction, all transactions between the seller and the buyer are monitored and the information between the seller and the buyer is encrypted, so that the online transaction of the electronic commerce is more reliable and safer for the seller and the buyer, and the method can be used for tracing and verifying the safe and mutual confirmation of the identity, the source and the authentication of the product.

Based on the same inventive concept, the embodiment of the present invention further provides a system for confirming product information, and as the principle of the problem solved by the system is similar to that of the foregoing method, the implementation of the system may refer to the implementation of the foregoing method, and repeated details are not repeated.

The embodiment of the invention also provides a system for confirming the product information, which comprises a transaction server, at least one buyer client and a seller client; the transaction server applies a method for confirming product information as described in any one of the above, so that all transactions between the seller and the buyer are monitored and information between the seller and the buyer is encrypted, thereby making the e-commerce online transaction more reliable and secure for the seller and the buyer, and being capable of being used for tracking and verifying the secure and interactive confirmation of product identity, origin and authentication.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
