The method for tracing the source of the target object provided by the embodiment of the present invention will be described below in conjunction with FIG. 1. As shown in FIG. The production situation and transaction situation of the target object are tracked, and when it is applied to the transaction scene, both parties to the transaction can have the same information on the source and quality of the commodity. Specifically, the traceability method of the target object shown in Figure 2 may include the following steps:

101: Obtain the first digital information of the target object, wherein the first digital information is digital information related to the production process of the target object in the production stage of the target object, the digital information includes but not limited to the raw materials required for the production of the target object, The place of manufacture of the target object and the manufacturer of the target object.

That is to say, in the production stage of the target object, the information of the raw materials required for the production of the target object (such as the type, model, place of production of the material, manufacturer of the material, production time of the material, and transportation of the material, etc.) can be obtained, Information such as the production place of the target object, the manufacturer of the target object, and the production time of the target object are used as the first digital information.

In the embodiment of the present invention, a feasible way to obtain the above-mentioned first digital information is to manually input the above-mentioned information by all parties involved in the production stage, such as the manufacturer of the required raw materials, the business personnel of the transportation company, and the The manufacturer manually enters the above information. For example, the system framework implementing the target object traceability method provides an information input interface, and the personnel of the above-mentioned parties manually input the above-mentioned information in the information input interface.

Another feasible way to obtain the above-mentioned first digital information is: in the production stage of the target object, from the production of the required raw materials, entering the site (entering the production workshop of the target object) and the production of the target object through artificial intelligence and multimedia technology collection the above information. For example, through artificial intelligence and multimedia technology, the identification information in the raw materials (such as the two-dimensional code recording the model, type, production time and other information of the raw materials), the manufacturer's certificate, and the identification information of the items transporting the raw materials (such as recording the transportation of the raw materials) Two-dimensional code of the situation) and the identification information of the target object (such as the two-dimensional code recorded with the model, type, production time and other information of the target object) for scanning, identification and information verification, so as to automatically transfer the information of the stylish product It is converted into the above-mentioned first digital information to realize automatic acquisition of the first digital information.

Another feasible way to obtain the above-mentioned first digital information is to combine the above-mentioned manual input method with the automatic acquisition method, for example, to obtain part of the above-mentioned first digital information through manual input, and to obtain the above-mentioned first digital information through automatic acquisition. The remaining information of the first digital information, or after the first digital information is obtained through automatic acquisition, and the automatically obtained first digital information is corrected through manual input.

However, it should be noted that the correction here is mainly correction of grammar and typos. This is because the above-mentioned first digital information involves various information such as the origin, materials, process, standards and manufacturers of the target object. Through these The information can determine whether the target object comes from the real place of origin and whether the real craftsmanship is used, so only the grammar and typos in the automatically obtained information are allowed to be corrected.

102: Generate identification information of the target object, generate a blockchain of the target object according to the identification information of the target object, and generate identification information of the blockchain.

It can be understood that: the identification information is an identifier used to distinguish different target objects, and one way to generate the identification information of the target object in the embodiment of the present invention is: related information of the target object, such as a picture of the target object, The logo and performance parameters are hashed to obtain the hash value of the target object, which can be used as the identification information of the target object. Then generate the blockchain of the target object according to the identification information of the target object, and the generated blockchain is shown in Table 1.

Table 1 Blockchain format

block header Identification information of the target object end of block

It can be seen from the above table 1 that the block chain of the target object directly adds the identification information of the target object to the data area of the block chain. Adding the above-mentioned first digital information to the data area of the blockchain can greatly reduce the amount of information in the blockchain, which is beneficial to the transmission of the blockchain.

Correspondingly, the identification information of the block chain is an identifier used to distinguish the block chains of different target objects. In the embodiment of the present invention, a feasible way of the identification information of the block chain is: block chain public key of the blockchain, and can publish the public key of the blockchain, so that the public key of the blockchain can be used as the query basis, that is, the public key of the blockchain can be used as the search condition to obtain the corresponding blockchain, and then you can According to the identification information of the target object in the blockchain, the corresponding target object is obtained, so as to obtain various pieces of digital information related to the target object.

103: Acquire at least the second digital information of the target object and the third digital information of the target object, wherein the second digital information is digital information related to the transportation process of the target object during the transportation stage of the target object, such as the second digital information Including but not limited to the transportation time of the target object, the transportation starting point and transportation focus corresponding to a certain transportation time, etc.

The third digital information is digital information related to the transaction status of the target object during the transaction stage of the target object. For example, the third digital information includes but is not limited to the transaction time of the target object, information on both parties to the transaction of the target object, and the like.

That is to say, for any target object, the embodiment of the present invention can obtain various pieces of digital information in different stages, such as the production stage, transportation stage and transaction stage, and for the acquisition method of the second digital information and the third digital information, please refer to Referring to the manner of acquiring the first digital information, this embodiment of the present invention will not be described again.

104: Bind the first digital information, the second digital information, and the third digital information to the blockchain, so that after querying the blockchain, you can obtain each piece of digital information bound to it to know the target The situation of the object at different stages, such as the situation of the raw materials in the production stage and the production situation of the target object (such as the production place), and then when the target object traceability method provided by the embodiment of the present invention is applied to the transaction scene, for both parties to the transaction For the buyer, it can grasp the same information about the source and quality of the target object.

One point that needs to be explained here is: after the block chain of the target object is generated, due to the time cost and expense cost of the production, transportation and transaction of the target object, there will be a certain delay in the digital information bound to the block chain. , but the embodiment of the present invention completes the release of the latest digital information through the update of each piece of digital information bound by the blockchain, and provides the latest peer-to-peer information for both parties to the transaction. And the block chain is generated with the beginning of the production stage of the target object, and changes with the track of the target object (such as caused by transportation or transaction), so that the nodes related to the target object (this node refers to the user, such as the seller in the transaction There are more and more parties and purchasers), so the embodiment of the present invention provides blockchain technology to allow other nodes to join, so as to realize the sharing of digital information bound by the blockchain.

105: Based on the identification information of the blockchain, provide various pieces of digital information bound to the blockchain. That is to say, the identification information of the blockchain can be used as a key word for querying various pieces of digital information. By inputting the identification information of the blockchain in the system framework implementing the method of traceability of the target object (the identification information of the blockchain can be exported to achieve sharing). ), you can find the corresponding blockchain through the identification information of the blockchain, and then find out the digital information bound to it according to the blockchain to realize digital information sharing, and the digital information indicates that the target object is in different stages The situation, such as the production time in the production stage, the transportation time in the transportation stage, and the information of both parties in the transaction stage, etc. Therefore, the production situation and transaction situation of the target object can be tracked through the digital information of different stages.

With the above technical solution, after the first digital information of the target object is obtained, the identification information of the target object is generated, the block chain of the target object is generated according to the identification information of the target object, and each piece of the target object in different stages Digital information, such as the first digital information in the production stage, the second digital information in the transportation stage, and the third digital information in the transaction stage are bound to the blockchain. Further, the identification information of the blockchain can be used as the query basis to provide information related to Each piece of digital information associated with the blockchain can obtain each piece of digital information of the target object through the identification information of the blockchain, and then track the production status and transaction status of the target object through each piece of digital information of the target object .

And the target object traceability method provided by the embodiment of the present invention can be applied to the transaction scene. By applying the target object traceability method provided by the embodiment of the present invention, both parties to the transaction can realize the traceability of the target object through each piece of digital information of the target object. Production status and transaction status are tracked, especially for the purchaser among the two parties to the transaction, information such as the source and quality of the target object can be grasped through various pieces of digital information, so that both parties to the transaction have the same information on the source and quality of the target object.

What needs to be explained here is that the identification information of the blockchain is only used to distinguish different blockchains, but it is impossible to determine which target object the blockchain belongs to through the identification information of the blockchain, and thus it is impossible to determine whether the target object is a What type of object, for example, it is impossible to determine whether the target object of the blockchain is an automobile product or an agricultural product, etc., so only the identification information of the blockchain is used as the basis of the query, and it needs multiple queries to obtain the desired target object For each digital information of the target object, the target object traceability method provided by the embodiment of the present invention can also: obtain the summary information of the target object, and bind the summary information with the block chain, and then can use the identification information of the block chain and The summary information of the target object is the basis of the query, providing various pieces of digital information bound by the blockchain.

The summary information is used as a brief description of the target object, at least to indicate the type and function of the target object, and for different target objects, there may be the same summary information, so the corresponding target of the blockchain can be determined through the summary information Which type and/or which function of the object belongs to the target object, that is to say, through the summary information, it can be determined whether the target object corresponding to the blockchain is the object that the transaction parties want to trade, and then through the blockchain bound to it The identification information queries each piece of digital information, so as to determine the final target object from at least one target object determined by the summary information.

Please refer to FIG. 3, which shows another flow chart of the target object traceability method provided by the embodiment of the present invention, which may include the following steps:

201: Obtain the first digital information of the target object, where the first digital information is digital information related to the production process of the target object in the production stage of the target object, the digital information includes but not limited to the raw materials required for the production of the target object, The place of manufacture of the target object and the manufacturer of the target object.

202: Generate identification information of the target object, generate a blockchain of the target object according to the identification information of the target object, and generate identification information of the blockchain.

In the embodiment of the present invention, step 201 is the same as step 101, and step 202 is the same as step 102, which will not be described in this embodiment of the present invention.

203: Associate the target object with the user information of the first user. The target object and the user information of the first user can be associated with the beginning of the target object production phase, and the user information of the first user is used to indicate which user the current owner of the target object is, so in the embodiment of the present invention , the user information of the first user may change as the trajectory of the target object changes.

For example, when the target object is in the production stage, the user information of the first user may be the information of the user who produced the target object, such as the manufacturer of the target object in the above-mentioned first digital information, and in order to indicate which user produced the target object, the first The user's user information includes but is not limited to the name of the manufacturer, the location of the manufacturer, and the registration time of the manufacturer, etc., so as to distinguish different first users through these information, so as to determine the user information of the first user corresponding to the target object In order to avoid the problem that actual manufacturers use OEM and other methods to entrust small factories to produce on their behalf.

204: Acquire at least the second digital information of the target object and the third digital information of the target object, wherein the second digital information is digital information related to the transportation process of the target object during the transportation stage of the target object, and the third digital information is Numerical information related to the transaction status of the target object during the transaction stage of the target object.

205: Bind the first digital information, the second digital information, and the third digital information with the blockchain.

In the embodiment of the present invention, step 204 is the same as step 103, and step 205 is the same as step 104, which will not be described in this embodiment of the present invention.

206: In the case where the third digital information indicates that the owner of the target object has been changed from the first user to the second user, obtain the user information of the second user, and modify the association between the target object and the user information of the first user to be the target object and User information association of the second user.

It can be understood that the third digital information is digital information related to the transaction status of the target object in the transaction stage of the target object, so it can be determined whether the owner of the target object has changed through the third digital information, such as the third digital information Include a parameter used to indicate the success of the transaction. When the value of the parameter is a preset value (such as 1), it means that the target object has been successfully traded in the transaction stage of the target object. At this time, the target object’s The owner changes, and then obtains the current owner information of the target object, such as the user information of the second user mentioned above, and then changes the association between the target object and the user information of the first user to the association between the target object and the user information of the second user.

In the embodiment of the present invention, the user information of both parties involved in a transaction—the first user (the owner of the target object before the transaction is successful) and the second user (the owner of the target object after the transaction is successful) is recorded in the above-mentioned In the three digital information, when it is determined that the owner of the target object changes, the user information of the second user can be directly obtained from the above third digital information, and associated with the target object.

What needs to be explained here is: in the first transaction of the target object, the first user is the producer of the target object, while in other transactions of the target object, the first user is the producer of the target object after the previous successful transaction owner. And whether the transaction is successful or not needs to be judged whether an instruction confirming that it can be traded has been received. When the instruction confirming that it can be traded is received, it means that the transaction is successful. The instruction confirming that it can be traded is issued by the terminal device of the first user. Each user's terminal device will receive transaction information, such as buyer information. When the first user confirms the transaction through the transaction information displayed on the first user's terminal device, the terminal device will issue an instruction to confirm that the transaction is possible.

207: Based on the identification information of the blockchain, provide various pieces of digital information bound to the blockchain.

With the above technical solution, when the third digital information indicates that the owner of the target object has changed from the first user to the second user, the association between the target object and user information can be changed, and the transaction status of the target object can be tracked.

In addition, the target object traceability method provided by the embodiment of the present invention may also include the steps of: obtaining the operation status of each blockchain, and adjusting the monitoring parameters according to the operation status of each blockchain, wherein the operation status of the blockchain includes but Not limited to: block height, number of transactions, number of users, and average block generation time, etc. The block height is used to record all transactions of the corresponding target object. As the number of transactions increases, the block height increases. The above information can Obtain the operation status of a block chain to determine whether the monitoring parameters need to be adjusted. If the monitoring parameters need to be adjusted, you can adjust the monitoring time, monitor the number of block chains, etc., and this monitoring method can be used for The disadvantages of blockchain decentralized technology play a complementary role.

The generating unit 12 is configured to generate identification information of the target object, generate a block chain of the target object according to the identification information of the target object, and generate identification information of the block chain. It can be understood that: the identification information is an identifier used to distinguish different target objects, and one way to generate the identification information of the target object in the embodiment of the present invention is: related information of the target object, such as a picture of the target object, The logo and performance parameters are hashed to obtain the hash value of the target object, which can be used as the identification information of the target object. Then, the block chain of the target object is generated according to the identification information of the target object, wherein the generated block chain is shown in Table 1 above.

It can be seen from the above table 1 that the block chain of the target object directly adds the identification information of the target object to the data area of the block chain. Adding the above-mentioned first digital information to the data area of the blockchain can greatly reduce the amount of information in the blockchain, which is beneficial to the transmission of the blockchain.

Correspondingly, the identification information of the block chain is an identifier used to distinguish the block chains of different target objects. In the embodiment of the present invention, a feasible way of the identification information of the block chain is: block chain public key of the blockchain, and can publish the public key of the blockchain, so that the public key of the blockchain can be used as the query basis, that is, the public key of the blockchain can be used as the search condition to obtain the corresponding blockchain, and then you can According to the identification information of the target object in the blockchain, the corresponding target object is obtained, so as to obtain various pieces of digital information related to the target object.
