Examples:
as shown in fig. 1, the real estate online on-road transaction management system provided in the first aspect of the present embodiment and based on satellite positioning includes, but is not limited to, a real estate transaction subsystem, a satellite positioning subsystem, a blockchain server and a user terminal, wherein the blockchain server is respectively in communication connection with the real estate transaction subsystem, the satellite positioning subsystem and the user terminal.
The real estate transaction subsystem is used for realizing online in-transit transaction of the real estate object and transmitting the obtained transaction data to the blockchain server in real time, wherein the transaction data comprises, but is not limited to, property right delivery time stamps of the real estate object, property right post-delivery ownership information and the like. The real estate object is real estate for carrying out transactions, and can be particularly but not exclusively, in-transit goods on transport means such as ships or trains. The specific manner of the online in-transit transaction is prior art content, so the transaction data is conventionally available. In detail, the transaction data includes, but is not limited to, key information of a trade contract such as transaction party information, transaction payment completion time stamp, transaction amount information and/or delivery time contract information, wherein buyer information in the transaction party information can be used as ownership information after the property is delivered, and the transaction payment completion time stamp can be used as the property delivery time stamp (i.e. time stamp when the property is changed).
The satellite positioning subsystem is used for realizing real-time satellite positioning of the movable target object and transmitting the obtained positioning data to the block chain server in real time. The specific manner of the real-time satellite positioning is also the prior art, for example, a satellite positioning module is bound on the real-time property marker, then the satellite positioning module receives navigation satellite signals and combines the prior art such as passive positioning technology, satellite navigation technology and satellite time service technology to obtain the positioning data of the real-time property marker in real time, and then the communication module connected with the satellite positioning module is utilized to transmit the positioning data to the blockchain server in real time. In detail, the satellite positioning subsystem may be, but is not limited to, a Beidou satellite navigation system.
The block chain server is used for carrying out uplink certification processing on the characteristic data of the movable target object, and carrying out real-time uplink certification processing on the transaction data and the positioning data. The characteristic data is a parameter that is formed during a marketing campaign and is sufficient to distinguish the subject matter from other subject matter, specifically, the characteristic data includes, but is not limited to, name, quantity, quality, price, fulfillment period, fulfillment location, fulfillment mode, packaging mode, inspection criteria/mode, settlement mode, photograph and/or number, etc. of the subject matter. The characteristic data can be used as NFT (all called Non-flexible Token) data of the movable target after being uplinked, which refers to Non-homogeneous universal evidence, and is essentially a trusted digital rights voucher with unique characteristics in a blockchain network, and the trusted digital rights voucher is a data object capable of recording and processing multidimensional and complex attributes on the blockchain. In addition, the specific modes of the uplink certification processing and the real-time uplink certification processing are the prior art content, for example, the data to be certified or the data abstract and the signature obtained after the hash calculation of the data to be certified are recorded in a new block of the blockchain.
The blockchain server is further used for, after receiving a query request from the user terminal for requesting to view the movable object, downlink the characteristic data and ownership information after title delivery in the recently uplink transaction data and feeding back the characteristic data and ownership information as a query response result to the user terminal, and further determining user permission firstly according to a matching result of user identity information in the query request and ownership information after title delivery in the uplink transaction data, and then feeding back the positioning data downlink conforming to the user permission to the user terminal as another query response result. The user terminal refers to a communication electronic device, such as a desktop computer, a notebook computer, a tablet computer, a smart phone, etc., held by a user (such as a transaction partner or a potential buyer, etc.), so that the query request may be manually initiated by the user after inputting the unique number of the real estate object to the user terminal. In addition, the specific way of performing data downlink and feeding back to the user terminal as a query response result is also the conventional technology.
Considering that there are various user identities, such as a historical ownership (i.e., a historical seller and a historical buyer), a current ownership (i.e., a current buyer) and/or other users (e.g., potential buyers), it is necessary to determine different rights possessed by different users for the purpose of clearly distinguishing legal responsibilities of different users, and to perform query responses of different rights. Specifically, according to the matching result of the user identity information in the query request and the proprietary information after the delivery of the property rights in the uplink transaction data, the user rights are determined first, and then the positioning data conforming to the user rights is downlink and fed back to the user terminal as another query response result, including but not limited to the following cases (a) - (C).
(A) And if the user identity information in the query request is found to be matched with the proprietary person information after the property delivery in the latest uplink transaction data, feeding back the positioning data which is uplink from the property delivery time stamp in the latest uplink transaction data to the current time stamp and the latest uplink transaction data to the user terminal as another query response result. This is the case where the user is the current owner, and thus by feeding back to the current owner a response of positioning data recorded from the title delivery time stamp in the last-uplink transaction data, the current owner's exclusive ownership of the real estate object can be ensured. In detail, the step of downlink the positioning data from the property delivery time stamp in the latest uplink transaction data to the current time stamp uplink and feeding back to the user terminal as another query response result includes: after the positioning data which is uplink from the property delivery time stamp in the latest uplink transaction data to the current time stamp is downlink, drawing to obtain first historical track data of the movable property target according to all the positioning data obtained by the downlink, and then feeding back the first historical track data to the user terminal as another query response result. The specific drawing manner of the first historical track data is that of the prior art, for example, all the positioning data acquired by the downlink may be fitted in a GIS geographic information system, so as to obtain the first historical track data from point a (i.e. the time stamp of moving the movable object to point a is the title delivery time stamp in the transaction data which is recently uplink) to point E (i.e. the positioning data which is uplink at the current time stamp) as shown in fig. 2. In addition, after the first historical track data is obtained, a movement path can be calculated, and the movement path is also fed back to the user terminal as another inquiry response result; and considering data transmission and processing delays, the accuracy of the time stamps may be appropriately rough, e.g., on the order of 1 minute, etc., in order to ensure simultaneity of the title delivery time stamps, satellite positioning time stamps, and uplink time stamps.
(B) And if the user identity information in the query request is found to be matched with the proprietary person information after the property delivery in certain non-latest transaction data, feeding back the positioning data which is uplink and recently uplink from the property delivery time stamp in the certain non-latest transaction data to the property delivery time stamp in next transaction data and/or the certain non-latest transaction data to the user terminal as another query response result, wherein the certain non-latest transaction data is the certain non-latest transaction data which is uplink, and the next transaction data is the next transaction data which is later than the certain non-latest transaction data. This is the case where the user is a historical owner, and thus, by feeding back to the historical owner a response of the positioning data recorded from the title delivery time stamp in the certain non-recent transaction data to the title delivery time stamp in the next transaction data, the historical owner's exclusive ownership of the movable object can be ensured. In detail, the step of downlink the positioning data, which is uplink from the title delivery time stamp in the certain non-latest transaction data to the title delivery time stamp in the next transaction data, and feeding back to the user terminal as another query response result, includes: after the positioning data which are up-linked from the property delivery time stamp in the certain non-latest transaction data to the property delivery time stamp in the next transaction data are down-linked, drawing second historical track data of the movable property object according to all the positioning data acquired by the down-link, and then feeding back the second historical track data to the user terminal as another query response result, wherein the next transaction data are the next transaction data which are up-linked later than the certain non-latest transaction data. The specific drawing manner of the second historical track data is that of the prior art, for example, the second historical track data shown in fig. 2 and from the point S (i.e. the time stamp of moving the real estate object to the point S is the title delivery time stamp in the certain non-latest transaction data) to the point a (i.e. the time stamp of moving the real estate object to the point a is the title delivery time stamp in the next transaction data, namely the last uplink transaction data) can be obtained. In addition, the transaction data also includes information of both transaction parties, the historical ownership is taken as a seller, and the next transaction data and the movement path calculated based on the second historical track data can be fed back to the user terminal as another inquiry response result.
(C) And if the user identity information in the query request is not matched with the proprietary person information after the property delivery in all the uplink transaction data, the positioning data which is recently uplink is downlink and is fed back to the user terminal as another query response result. This is the case when the user is another user, and thus by feeding back the positioning data responses recorded in real time to the other user, it is possible to ensure limited awareness of the other user of the real estate object.
