And determining the exchange rate between the second point data type and the first point data type according to the second point data type and determining second data in the second point exchange information according to the exchange rate. For example, similar to the previous embodiment, the merchant collects the bank points of the tenderer, the value of the first point data is 1000 points, the national points are provided by the user, the server determines the exchange rate between the bank points of the tenderer and the national points according to the point types supported by the user terminal and the unique identification, namely the national points, so that 900 national points needed to be provided by the user can be obtained, and the second point data in the second point exchange information is 900 national points.
As one embodiment of the present invention, transferring the second credit data to the server account address via the blockchain network further comprises: and the server verifies the second integral data transferred by the account address of the user terminal, and if the verification is passed, the server respectively sends a conversion completion notification to the scanning equipment and the user terminal. After the user terminal account address transfers the second point data to the server account address, the server verifies whether the value of the second point data transferred by the user terminal account address is equal to the value of the second point data in the second point exchange information, and if so, the server verifies that the value of the second point data transferred by the user terminal account address is equal to the value of the second point data in the second point exchange information. Further, the server records the point exchange and sends an exchange completion notification to the user terminal and the scanning device respectively.
As one embodiment of the present invention, the server verifying the second credit data transferred by the account address of the user terminal further comprises: and the server scans the account address of the server according to the preset time interval, and when the scanned account address of the server receives the second point data transferred by the account address of the user terminal, and the value of the second point data transferred by the account address of the user terminal is equal to the value of the second point data in the second point exchange information, the verification is passed. The server is connected with the user terminal in a long way, the account address of the server is scanned according to a preset time interval, whether the corresponding account address of the user terminal transfers second point data or not is found in the exchange list, whether the value of the second point data is equal to the value of the second point data in the second point exchange information or not is judged, if so, the user terminal is considered to finish the operation of transferring the second point data to the account address of the server, and verification is passed.
In another aspect, the server verifying the second credit data for the user terminal account address transfer further comprises: and the server scans the account address of the user terminal according to the preset time interval, and when the second point data scanned to the account address of the user terminal is reduced and the value of the reduced second point data is equal to the second point data in the second point exchange information, the verification is passed. The server obtains the user terminal account address and the numerical value of the second point data to be converted according to the conversion details, scans the user terminal account address according to a preset time interval, and verifies whether the user terminal account address is reduced by the second point data. When the second point data is reduced and the value of the reduced second point data is equal to the value of the second point data in the second point exchange information, the user terminal is considered to finish the operation of transferring the second point data to the server account address, the verification is passed,
as one embodiment of the present invention, the server transferring the first integral data to the merchant account address further comprises: and the server exchanges the second point data transferred by the account address of the user terminal according to the exchange rate to obtain corresponding first point data, and transfers the first point data to the account address of the merchant. After the user terminal account address transfers the second point data to the server account address, the second point data transferred by the user terminal account address is converted into the first point data received by the corresponding merchant according to the exchange rate of the first point data and the second point data. For example, a merchant receives a banking point of interest, but the user terminal transfers the national aviation point of interest, the server converts the national aviation point of interest of the user into the banking point of interest of the merchant according to the exchange rates of the two different points, and transfers the converted banking point of interest of the merchant to the account address of the merchant.
The digital rights proving conversion system can realize conversion among different types of points, realize conversion among data with different attributes in a blockchain network, eliminate the difference of the data with different attributes in the blockchain network and enable the data with different attributes in the blockchain network to be fused.
Fig. 2 is a data flow diagram of a blockchain-based integral conversion system according to an embodiment of the present invention, where the data flow diagram specifically includes:
step 101, a user logs in.
The user logs in the APP for point exchange on the user terminal, and can log in through an account number and a password or can recognize login through biological characteristics (such as fingerprints and faces).
Step 102, the user terminal generates a unique identification.
The user terminal may generate a unique identification for user point redemption, such as a bar code or two-dimensional code, based on a user ID corresponding to the user terminal account address.
Step 103, the scanning device acquires first integral data.
The merchant inputs the first point data of the current point exchange through the scanning device or inputs the first point data on other terminals, and then sends the first point data to the scanning device. The first point data at least comprises a merchant account address and can also comprise the value and the type of the first point data of the current point exchange. Specifically, the merchant provides a service of exchanging gifts by using the bank points of the tenderer, the number of points required for exchanging gifts is the value of the first point data, and the bank points of the tenderer are the type of the first point data.
Step 104, the scanning device reads the unique identification.
The scanning device obtains the unique identifier of the user terminal by scanning or other data transmission modes, thereby obtaining the relevant information of the user terminal, such as the user ID.
Step 105, the scanning device generates first point redemption information.
The scanning device generates first point exchange information according to the first point data and the unique identification of the user terminal. The first point exchange information includes basic information for completing the current point exchange, such as merchant account address, user ID, value and type of the first point data of the current point exchange, etc.
Step 106, the scanning device sends the first point redemption information.
The scanning device sends the generated first point exchange information to the server.
In step 107, the server generates second point exchange information according to the first point exchange information and the exchange rate.
And the server obtains the account address of the user terminal and the second point data type supported by the user terminal according to the user ID in the first point exchange information, wherein the second point exchange information at least comprises the server account address generated by the server and second point data corresponding to the first point data. The service determines second point data in the second point redemption information based on the redemption rate between the second point data type and the first point data type supported by the merchant. For example, the merchant collects the bank points of the tenderer, the value of the first point data is 1000 points, the national points can be provided in the account address of the user, the server can determine the exchange rate between the bank points of the tenderer and the national points (or according to the exchange rate of the bank points of the tenderer and the national points provided by a third party), the user can obtain the national points 900, and the second point data in the second point exchange information is 900 national points.
When the server is consistent with the point types supported by the user terminal, the server can directly determine the exchange rate according to the first point data type and the second point data type. When the point types supported by the server and the user terminal are inconsistent, the point types supported by the user terminal are matched according to the unique identification of the user terminal, and then the exchange rate of the point types with the first point data type is determined.
Step 108, the server locates the user terminal and sends the second point redemption information.
The first point exchange information received by the server has a unique identifier of the user terminal, and the unique identifier has information, such as an IP address of the user terminal, which can enable the server to establish a connection with the user terminal. And the server establishes connection with the user terminal through the IP address of the user terminal, and sends the second point exchange information to the user terminal.
In step 109, the user terminal generates transfer information.
And the user terminal generates transfer information according to the second point exchange information, wherein the transfer information is used for transferring second point data from the account address of the user terminal to the account address of the server, and the transfer information comprises exchange details and the like corresponding to each point exchange.
In step 110, the user terminal signs the transfer information using the account address private key of the user terminal. Step 111, the user terminal account address transfers the second credit data to the server account address.
The user terminal account address transfers the second point data to the server account address in the second point exchange information, and specifically, the type of the transferred second point data is a type that can be provided by the user, for example, the user provides national aviation points.
In this step, the digital rights verification transfer of the user terminal account address to the server account address is accomplished through the blockchain network. The blockchain network needs to perform consensus verification on transfer information, wherein the consensus verification is that a blockchain node performs consensus verification on a signature of a user terminal (the transfer information which is diverted to a server account address is signed by using a private key of the user terminal account address) and a point of the user terminal account address, the user terminal generates a digest according to encrypted transaction data, which can be a part of the encrypted transaction data (for example, 5% of the beginning of the encrypted transaction data), signs the part of the digest by using the private key of the user terminal account address, and then sends the encrypted transaction data and the signature to the blockchain node. After a certain block link point receives the encrypted transaction data and the signature, the signature is decrypted by using a public key of an account address of a user terminal to obtain a summary of the encrypted transaction data, the decrypted summary is compared with the received encrypted transaction data, if the decrypted summary is consistent with the received encrypted transaction data (for example, the initial 5% of the encrypted transaction data is the same), the encrypted transaction data is not tampered, and account points can support the point exchange transaction, namely, the common identification verification is passed, and the encrypted transaction data is stored into a local block chain after the common identification verification is passed in the block chain node.
Step 112, the server verifies the second credit data transferred by the account address of the user terminal.
The server can obtain the account address of the user terminal according to the exchange details in the transfer information, and the server scans the account address of the user terminal in the blockchain network in real time. And when the second point data scanned into the account address of the user terminal is reduced, and the value of the reduced second point data is equal to that of the second point data in the second point exchange information, the verification is passed, and the server records the point exchange.
The server redeems and transfers the first credit data to the merchant account address, step 113.
After the verification is passed, the server exchanges the second point data transferred from the account address of the user terminal according to the type of the first point data required by the merchant. Specifically, the user provides 900 national aviation credits, the merchant receives the banking credits of the sponsor, and the server converts the 900 national aviation credits into 1000 banking credits of the sponsor according to the exchange rate of the two credits and transfers the 1000 banking credits from the server account address to the merchant account address.
Or transferring the first point data in the server account address to the merchant account address according to the information that the account address transfer of the user terminal is successful to the server account address.
Step 114, the service network sends a redemption completion notification to the scanning device and the user terminal.
After the server verifies the second point data transferred by the account address of the user terminal, the server sends a redemption completion notification to the user terminal.
The point conversion system can realize conversion among different types of points, realize conversion among data with different attributes in a blockchain network, eliminate the difference of the data with different attributes in the blockchain network and enable the data with different attributes in the blockchain network to be fused.
FIG. 3 is a data flow diagram of a blockchain-based integral conversion system according to another embodiment of the present invention, including:
step 201, a user logs in to acquire an authorization instruction.
The user logs in the APP for point exchange on the user terminal, and can log in through an account number and a password or can recognize login through biological characteristics (such as fingerprints and faces). After the user logs in, the user needs to obtain the authorization of the user to perform point exchange, and the user selects the point exchange function to be opened through operating the user terminal, so that an authorization instruction is issued to the user terminal.
Step 202, the user terminal generates the point exchange function starting application information and signs by using a private key.
After receiving the authorization instruction, the user terminal generates point exchange function opening information (the format of the appointed point exchange function opening application instruction can be used) and signs the point exchange function opening by using the private key of the user account address of the user terminal.
Step 203, the user terminal establishes connection with the server and sends the public key of the user and the signed point exchange function opening information.
The user terminal establishes long connection with the server, the long connection can be http connection, and the user terminal sends signed point exchange function starting information, user account address and public key to the server.
Step 204, the server verifies the point redemption function opening information.
And the server verifies the signed point exchange function starting information, namely, whether the signature is correct and valid or not is verified by utilizing the public key of the user. After the verification is passed, storing the account address of the user terminal in the server, which indicates that the user opens the point exchange function. And sending an authorization success notification to the user terminal.
Step 205, the server generates a unique identifier of the point exchange transaction according to the request of the user terminal, and sends the unique identifier of the point exchange transaction to the user terminal.
When the user terminal finishes the starting of the point exchange function, the user performs each point exchange operation, the user terminal establishes connection with the server, and the public key of the user, the signed point exchange transaction application information and the user account address are sent to the server. The point redemption transaction application information may include the number of the point redemption transaction application, the type of points that are present in the user account address (or the category of the user's second point data in the current point redemption transaction specified by the user). And the server verifies the signed point exchange transaction application information, namely, verifies whether the signature is correct and valid or not by utilizing the public key of the user. After verification is passed, generating a unique identifier of the point exchange transaction, storing a user terminal account address (optional), a unique identifier corresponding to the point exchange transaction and a time stamp (such as time for generating the unique identifier of the point exchange transaction) of the point exchange transaction at a server side, wherein the time stamp is used for judging whether the point exchange request is overtime in the later point exchange process by the server, if the time stamp is compared with the current time to exceed a time threshold, providing the point exchange service is refused, and if the time stamp is compared with the current time to exceed 2 minutes, judging that the current point exchange service has a safety risk. The server sends the unique identifier of the point exchange transaction to the user terminal, wherein the unique identifier of the point exchange transaction can be a character string generated for each point exchange transaction request of the user terminal, and each generated character string is different.
In step 206, the scanning device obtains first integral data.
The merchant inputs the first point data of the current point redemption through the scanning device, or inputs the first point data to the scanning device, which may be a scanner or a computer, at other devices or terminals. The first point data at least comprises a merchant account address and can also comprise the value and the type of the first point data of the current point exchange. Specifically, the merchant provides a service of exchanging gifts by using the bank points of the tenderer, the number of points required for exchanging gifts is the value of the first point data, and the bank points of the tenderer are the type of the first point data.
In step 207, the scanning device reads the user information.
The scanning device obtains user information of the user terminal in a scanning or other data transmission mode, wherein the user information can comprise unique identification of the point exchange transaction at this time, an account address of the user terminal, a point type of the user and the like, the user information can be presented in a two-dimensional code mode, the user information is obtained by scanning the scanning device, or the user information is obtained in a data information mode in a near field communication mode and the like, and the user information is unique and can be also called as the unique identification.
At step 208, the scanning device generates first point redemption information.
The scanning device generates first point exchange information according to the first point data and user information of the user terminal. The first point exchange information comprises basic information for completing current point exchange, such as merchant account address, user terminal account address, numerical value of first point data, point type corresponding to the first point data, point exchange transaction unique identification and the like.
Step 209, the scanning device transmits the first point redemption information.
The scanning device sends the generated first point exchange information to the server.
Step 210, the server generates second point exchange information according to the first point exchange information and the exchange rate.
The server verifies whether the unique mark of the point exchange transaction exists truly according to the unique mark of the point exchange transaction in the first point exchange information, and refuses the point exchange request if the unique mark does not exist; verifying whether the difference value between the current time and the time stamp exceeds a time threshold, rejecting the point exchange request if the difference value exceeds the time threshold, otherwise, allowing the point exchange request; it may also be verified whether the parameters of the point redemption transaction, such as the point type, are consistent with the point type supported by the user account in the user terminal point redemption transaction application message. The second point redemption information includes at least the server account address generated by the server and second point data corresponding to the first point data. The server determines second point data in the second point exchange information according to the exchange rate between the second point data type and the first point data type supported by the merchant. For example, the merchant collects the bank points of the tenderer, the value of the first point data is 1000 points, the national aviation points are provided by the user, the server can determine the exchange rate between the bank points of the tenderer and the national aviation points according to the preset exchange rate between various points, the user can obtain 900 national aviation points required to be provided by the user, and the second point data in the second point exchange information is 900 national aviation points.
When the server is consistent with the point types supported by the user terminal, the server can directly determine the exchange rate according to the first point data type and the second point data type. When the types of the points supported by the server and the user terminal are inconsistent, the types of the points supported by the user terminal are matched according to the types of the points in the account address of the user terminal, and then the exchange rate of the second type of the point data and the first type of the point data, which can be provided by the user terminal, is determined.
The integration pointed by the embodiment of the invention is one of digital rights and interests evidences, and the method provided by the embodiment of the invention can realize conversion among different digital rights and interests evidences.
Step 211, the server sends second point exchange information to the user terminal.
The server sends the second point exchange information to the user terminal through the long connection established with the user terminal.
In step 212, the user terminal generates transfer information.
And the user terminal generates transfer information according to the second point exchange information, wherein the transfer information is used for transferring second point data from the account address of the user terminal to the account address of the server, and the transfer information comprises exchange details and the like corresponding to each point exchange.
In step 213, the user terminal signs the transfer information using the account address private key of the user terminal.
Step 214, the user terminal account address transfers the second credit data to the server account address.
The user terminal account address transfers the second point data to the server account address in the second point exchange information, and specifically, the type of the transferred second point data is a type that can be provided by the user, for example, the user provides national aviation points.
In this step, the digital rights verification transfer of the user terminal account address to the server account address is accomplished through the blockchain. The method comprises the steps that account transfer information needs to be subjected to consensus verification, namely, a blockchain node performs consensus verification on a signature of a user terminal (the account transfer information which is diverted to a server account address is signed by using a private key of the user terminal account address) and an integral of the user terminal account address, the user terminal generates a digest according to encrypted transaction data, the digest can be a part of the encrypted transaction data (for example, 5% of the beginning of the encrypted transaction data), the private key of the user terminal account address is used for signing the digest, and then the encrypted transaction data and the signature are sent to the blockchain node. After a certain block link point receives the encrypted transaction data and the signature, the signature is decrypted by using a public key of an account address of a user terminal to obtain a summary of the encrypted transaction data, the decrypted summary is compared with the received encrypted transaction data, if the decrypted summary is consistent with the received encrypted transaction data (for example, the initial 5% of the encrypted transaction data is the same), the encrypted transaction data is not tampered, and account points can support the point exchange transaction, namely, the common identification verification is passed, and after the block link point passes the common identification verification, the encrypted transaction data is stored into a local block chain.
Step 215, the server verifies the second credit data transferred by the user terminal account address.
The server scans server account addresses in the blockchain network in real time. And when the server account address is scanned to receive the second point data transferred from the user terminal account address, and the value of the transferred second point data is equal to the value of the second point data in the second point exchange information, the verification is passed.
The server redeems and transfers the first credit data to the merchant account address, step 216.
After the verification is passed, the server exchanges the second point data transferred from the account address of the user terminal according to the type of the first point data required by the merchant. Specifically, the user provides 900 national aviation credits, the merchant receives the banking credits of the sponsor, and the server converts the 900 national aviation credits into 1000 banking credits of the sponsor according to the exchange rate of the two credits and transfers the 1000 banking credits to the account address of the merchant. In this step, the transfer is also performed using the blockchain technique, and reference is made to the foregoing steps.
In step 217, the server sends a redemption completion notification to the scanning device and the user terminal.
After the server verifies the second point data transferred by the account address of the user terminal, the server sends a redemption completion notification to the user terminal.
In addition, the user may select a second point data type for exchanging the first point data, and in step 210, the second point exchange information generated by the server includes the server account address and exchange rates of the first point data type and a plurality of different point types. In step 212, the user selects the value and type of the second integral data on the user terminal and generates corresponding transfer information, and in step 213, the user terminal signs the transfer information using the private key. In step 214, the user terminal transfers the corresponding second integration data to the server. In step 215, the server validates the second integral data. And steps 216 and 217 are performed to complete the transfer of the first credit data from the server account address to the merchant account address.
