It should be understood that, the current order request refers to an order request generated after a user has a transaction consensus with a merchant, and corresponding merchants are different according to different types of goods, so that the obtained order request is different, in order to improve the confidentiality of user privacy information, before a user key pair is sent to a merchant, a public key in the user key needs to be encrypted, and the public key is sent to the merchant through a data network or wireless WIFI after encryption is completed.
Step S20, the merchant receives the encrypted second public key, obtains a merchant key pair, decrypts the encrypted second public key according to a first private key of the merchant key pair, obtains a second public key, obtains current commodity information, encrypts the current commodity information according to the second public key, and sends the second public key and the encrypted current commodity information to the express delivery terminal.
It can be understood that, since the public key and the private key in the key pair are in a one-to-one correspondence relationship, the key pair has a strong pertinence, the notion of the name is that after the data is encrypted by the current public key, the encrypted data can only be decrypted by the private key corresponding to the current public key, for example, the key pair is a, the public key a1 and the private key a2, after the data B is encrypted by the a1, if the data B is desired to be obtained, the data B can only be obtained after the decrypted data B is decrypted by the private key a2, the process of encrypting and decrypting the data can be completed in the block chain, that is, the obtained data is sent to the block chain to encrypt the data, the block chain decrypts the data before the data needs to be used, and then operates the data, the current commodity information is commodity information obtained by the current order request, the commodity information purchased by the user is packaged into the target commodity information after the current commodity information and the second public key are obtained, so that the information transmission efficiency is improved.
Step S30, the express delivery transport end receives the second public key and the encrypted current commodity information, obtains area location information and contact information of the user according to the second public key, transports a commodity corresponding to the encrypted current commodity information to the area location information according to the area location information, obtains corresponding transport completion information, and sends the transport completion information to the user end and the express delivery agent end through the contact information.
It should be understood that the area location information refers to location information of a street or a cell in a receiving address of a user, and is not specific location information of the user, such as a building number unit number, a room number, and the like, the contact information refers to a contact way in the receiving address of the user, and is generally a mobile phone number, the transportation completion information refers to completion information after the commodity is transported to the area location, and includes the specific location information of the area location and arrival information after the commodity arrives at the area location, and after the transportation completion information is obtained, the transportation completion information needs to be sent to the user to remind the user that the target commodity arrives.
And step S40, the express delivery substitute receiving end receives the transportation completion information, generates a corresponding pickup two-dimensional code according to the transportation completion information, and sends the pickup two-dimensional code to the user side, so that the user side can realize self-pickup of the target commodity according to the pickup two-dimensional code.
It can be understood that after the transportation completion information is received, it is necessary to determine whether the user needs to pick up the package by himself or deliver the package by the courier according to the user demand information, and if the user demand is that the package needs to be picked up by himself at this time, the identification information in the transportation completion information is extracted, and a corresponding package pickup two-dimensional code is generated according to the identification information, where the identification information may be an order number or an order number, and this embodiment does not limit this, and explains by taking the order number as an example.
In this embodiment, a user side responds to a current order request of a user, obtains a user key pair based on the current order request, obtains a merchant key pair, and encrypts a second public key in the user key pair according to a first public key in the merchant key pair; the merchant terminal decrypts the encrypted second public key according to the first private key in the merchant key pair to obtain a second public key, and encrypts the current commodity information according to the second public key; the express delivery end obtains the regional position information and the contact information of the user according to the second public key, and transports the target commodity corresponding to the encrypted current commodity information to the regional position information according to the regional position information to obtain corresponding transportation completion information; the express delivery agent receiving end generates a corresponding pickup two-dimensional code according to the transportation completion information, sends the pickup two-dimensional code to the user side, and encrypts commodity information through the user key pair, the merchant key pair and the express delivery key pair so that a user can pick up commodities by himself through a private key in the key pair, and therefore the danger of information leakage can be effectively reduced.
