It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
As described in the background art, the artwork is subjected to traceability management, clear and complete circulation records are provided, the occurrence of fake behaviors can be reduced, and the healthy development of the industry is facilitated. The existing artwork is traced based on RFID technology, RFID electronic tags are separated from the artwork, and related problems are easy to occur.
Therefore, the application provides the artwork tracing method based on the blockchain, and the artwork tracing management is better realized based on the non-tamper property and the distributed billing characteristic of the blockchain.
In an embodiment, as shown in fig. 1, the artwork tracing method based on the blockchain provided by the application includes:
step S110, obtaining product description data for representing an artwork entity;
unlike ordinary commodities, the artwork is required to realize reliable anti-counterfeiting identification on specific artwork individuals, and based on the fact, the product description data comprise first data used for bearing general description information of the product and second data used for bearing anti-counterfeiting characteristic information of the product;
for example, the artwork entity belongs to an artwork, such as a cloisonne vase, the first data in the product description data of the cloisonne vase can be the whole image data of the vase, the second data can be the high-definition image data of the anti-counterfeiting mark left when the cloisonne vase is manufactured, and it is easy to understand that the whole image data and the high-definition image data can be obtained by related shooting means when the vase is manufactured.
After obtaining the product description data, step S120 may be performed, based on the product description data, deploying an intelligent contract on the blockchain platform to create and generate a Non-homogeneous certificate NFT (Non-homogeneous Token) corresponding to the artwork entity, where the intelligent contract has a function of appending a rights change record to the contract object;
NFT belongs to the blockchain technology, which can be understood as an intelligent contract on one blockchain. In step S120, an intelligent contract may be deployed on the blockchain platform according to the product description data of the artwork entity, and an NFT corresponding to the artwork entity is created and generated, that is, the artwork entity Token is turned into n, and the intelligent contract that issues the NFT has the function of adding a rights and interests change record to the contract object, so as to implement traceability management of the artwork entity based on the intelligent contract.
It is easy to understand that, to ensure the integrity of tracing, the tracing of the full life cycle of the artwork is implemented, and steps S110 and S120 may be performed after the artwork entity is produced or authored.
After the NFT is created in step S120, step S130 may be performed, where in the artwork entity circulation process, the non-homogeneous pass is subjected to corresponding rights change according to the intelligent contract based on the input of the user, and a rights change record of the non-homogeneous pass is generated, so that traceability management of the artwork entity is implemented based on the historical rights change record of the non-homogeneous pass.
According to the technical scheme, the non-homogeneous pass corresponding to the artwork entity is generated according to the product description data of the artwork entity, the rights and interests change records are added to the non-homogeneous pass in the artwork entity circulation process based on the specific intelligent contract, and then the traceability management of the artwork entity is realized based on the historical rights and interests change records. Based on the configuration of intelligent contracts and the non-tamper-evident and distributed billing characteristics of block chains, the traceability management of artwork is better realized.
In order to facilitate understanding of the technical solution of the present application, another embodiment of the present application is described below.
Firstly, step S210 is performed to obtain product description data for representing an artwork entity;
in step S210 of this embodiment, in order to improve reliability of product description data of an artwork, general product description information includes 3D scan information of a product as a whole, and product anti-counterfeiting feature information includes 3D scan information of local features of the product;
in practical implementation, 3D scanning may be performed on the artwork entity when the artwork entity is produced (related 3D scanning techniques may be found in the prior art, and detailed description of the present application is not provided herein), and the first data and the second data may be generated based on the 3D scanning information obtained by the scanning;
in addition, in this embodiment, as shown in fig. 2, the first data and the second data are also stored on a non-public authentication data platform (in fig. 2, the 3D scan data corresponds to the first data, and the security feature data corresponds to the second data), and in this embodiment, the non-public authentication data platform is configured to perform the maintenance of the first data and the second data, which is beneficial to the actual implementation of the authentication service for the corresponding artwork entity.
It will be readily appreciated that the second data (the security feature data in fig. 2) may also carry other product security feature information, such as encoded information of an RFID tag embedded in an artwork entity, etc., based on actual needs.
Step S220 is carried out, based on the product description data, intelligent contracts are deployed on the blockchain platform to create and generate non-homogeneous pass corresponding to the artwork entity, wherein the intelligent contracts have the function of adding rights and change records on contract objects;
since the data amounts of the first data and the second data are generally large (for example, the first data and the second data carrying 3D scan information in this embodiment), in order to facilitate deployment of the smart contract on the blockchain platform, in step S220, the smart contract is deployed on the blockchain platform based on the product description data, and the smart contract may be deployed on the blockchain platform according to metadata of the product description data;
specifically, in this embodiment, for convenience of implementation, the first data and the second data are hashed respectively, so as to obtain a first hash value and a second hash value correspondingly (as shown in fig. 2, where the first hash value and the second hash value correspond to the product fingerprint in fig. 2); and performing intelligent contract deployment according to the first hash value and the second hash value.
In addition, in practice, the artwork entity may belong to an artwork manufactured by mass production, such as the cloisonne vase mentioned above, and in order to facilitate the traceability management of the whole life cycle, the product description data further includes third data for carrying product production release information (the generation of the third data may be generated based on the input related information of the user);
for example, the product production distribution information includes product source information (including artist information, vendor information, copyright parties, etc.), product distribution total amount and distribution number information, default owner information. In this case, in a practical implementation, the smart contract deployment is correspondingly performed according to the first hash value, the second hash value and the third data (which corresponds to the production release information of the NFT in fig. 2).
Similarly, when the data size of the third data is larger, the third data can be stored in the related data platform, and intelligent contract deployment is performed based on the first hash value, the second hash value and the metadata of the third data.
Then, step S230 may be performed, in the process of transferring the artwork entity, the non-homogeneous pass is subjected to corresponding rights change according to the intelligent contract based on the input of the user, and the rights change record of the non-homogeneous pass is generated, so that the traceability management of the artwork entity is realized based on the historical rights change record of the non-homogeneous pass.
In this embodiment, during the process of transferring the artwork entity, based on the industry rule or management rule of the transaction transfer, the transfer of the artwork entity must be completed to complete the corresponding rights and interests change of the non-homogeneous certificate, which is considered as a legal and effective transfer.
How the traceability management is implemented in the present application is described herein.
Specifically, to implement the rights change for the non-homogenous pass, in this embodiment, the smart contract is configured to:
the process of rights change is initiated by the owner of the pass and confirmed by the receiver of the pass;
after the rights are changed, signature information of both the change-related parties is additionally recorded on the pass (corresponding to the authentication flow information of the NFT in fig. 2).
It is easy to understand that, in the implementation of the above configuration of the smart contract, both parties (or both transaction parties) requiring the circulation of the artwork entity are users of the blockchain platform, weight changes are performed on NFTs corresponding to the artwork entity on the blockchain platform, and signature information of both parties after the transaction is additionally recorded on the pass (similar to the distributed accounting of the blockchain). For example, in this embodiment, the flow logic of the ownership change can be as shown in FIG. 3.
In fig. 3, the current legal owner of the artwork entity (which also correspondingly holds the corresponding non-homogeneous pass on the blockchain platform) initiates the rights and interests changing flow of the non-homogeneous pass, the system background first judges whether the initiation is initiated by the rights and interests owner (i.e. whether the non-homogeneous pass is held) and then processes the rights and interests changing flow based on the flow logic shown in fig. 3, and under the condition that the intelligent contract related rule is satisfied, signature information of both parties after the transaction is additionally recorded on the pass and interests changing record is formed.
In this way, in each process, the above-mentioned process is carried out, so that the history rights change record of the non-homogeneous pass is generated, and the rights change record is recorded with the signature information of both transaction parties in each transaction change, so that the tracing management of the artwork entity can be realized based on inquiring the history rights change record of the non-homogeneous pass.
In addition, the process of transferring the artwork generally involves an identification step of transferring the artwork entity. Accordingly, in this embodiment, the smart contract further has a function of writing authentication information on the contract object, and the smart contract is further configured to:
the process of writing the authentication information is initiated by the owner of the pass;
after the signature of the authentication institution involved in authentication, the signature of the authenticators, and the metadata of the authentication conclusion are additionally recorded on the pass, the process of writing the authentication information is completed.
In this embodiment, for example, the flow logic for writing authentication information is as shown in fig. 4, and the written authentication information corresponds to the authentication flow information in fig. 2.
It is easy to understand here that, in the practical implementation of the authentication link, the relevant authenticator (that needs to have relevant qualification rights) may acquire product description data (such as the aforementioned first data and second data carrying relevant 3D scan information) of the artwork entity to be authenticated according to the product fingerprint in the NFT onto the authentication data platform, and perform 3D scan again on the artwork entity to be transacted by adopting relevant technical means, and perform authentication based on the data acquired by this scan and the product description data (such as the second data).
The technical scheme of the application is mainly used for reducing the occurrence of fake making behaviors, in the embodiment, the identification conclusion and the related information of the identifier are additionally recorded on the non-homogeneous general certificate, the traceable related information is further perfected, the non-autonomous or illegal behaviors of the identifier are reduced, and the healthy development of the industry is also facilitated.
