In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background technology, the artwork is subjected to traceability management, clear and complete circulation records are provided, the occurrence of counterfeiting behaviors can be reduced, and the healthy development of the industry is facilitated. The existing artwork tracing based on the RFID technology is realized, and the RFID electronic tag is separated from the artwork, so that the related problems are easily caused.
Therefore, the method for tracing the source of the artwork based on the block chain is provided, and the traceability management of the artwork is better realized based on the characteristics of non-tamper property and distributed accounting of the block chain.
In an embodiment, as shown in fig. 1, the method for tracing art works based on a blockchain includes:
step S110, acquiring product description data for representing an artwork entity;
different from common commodities, the artwork needs to realize reliable anti-counterfeiting identification for specific artwork individuals, and based on this, in this embodiment, the product description data includes first data for bearing general description information of the product and second data for bearing anti-counterfeiting feature information of the product;
for example, the art entity belongs to a craft art, 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, and the second data can be the high-definition image data of the anti-counterfeiting mark left when the cloisonne vase is manufactured.
After the product description data is obtained, step S120 may be performed to deploy an intelligent contract on the blockchain platform based on the product description data to create and generate a Non-homogeneous document NFT (Non-fungal Token) corresponding to the artwork entity, where the intelligent contract has a function of appending a property change record on the contract object;
NFT belongs to the technology of block chain, and NFT can be understood as an intelligent contract on a block chain. In step S120, an intelligent contract may be deployed on the blockchain platform according to the product description data of the artwork entity, to create and generate an NFT corresponding to the artwork entity, that is, to say, the artwork entity is Token-based, and the intelligent contract issuing the NFT has a function of adding a property change record to the contract object, so as to implement traceability management of the artwork entity based on the intelligent contract.
It is understood that, to ensure the integrity of the tracing and to realize the tracing of the whole life cycle of the artwork, steps S110 and S120 may be performed after the entity of the artwork is produced or created.
After the NFT is created in step S120, step S130 may be performed, in the process of transferring the artwork entities, corresponding ownership change is performed on the non-homogenization voucher according to the intelligent contract based on the input of the user, and an ownership change record of the non-homogenization voucher is generated, so that the source tracing management of the artwork entities is realized based on the historical ownership change record of the non-homogenization voucher.
According to the technical scheme, the non-homogeneity certificate corresponding to the artwork entity is generated according to the product description data of the artwork entity, and based on a specific intelligent contract, the ownership change record is added to the non-homogeneity certificate in the circulation process of the artwork entity, so that the source tracing management of the artwork entity is realized based on the historical ownership change record. Based on the configuration of the intelligent contract, the non-tamper property of the block chain and the distributed accounting characteristics, the traceability management of the artwork is better realized.
To facilitate understanding of the technical solutions of the present application, the technical solutions of the present application will be described below with reference to another embodiment.
Firstly, step S210 is carried out, and product description data used for representing an artwork entity is obtained;
in step S210 of this embodiment, in order to improve the reliability of the product description data of the artwork, the general product description information includes 3D scanning information of the whole product, and the anti-counterfeiting feature information includes 3D scanning information of the local feature of the product;
in practical implementation, when the production of the artwork entity is completed, 3D scanning may be performed on the artwork entity (related 3D scanning technology may be present in the prior art, and details are not described here), and the first data and the second data are generated based on the 3D scanning information obtained by 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).
It is easily understood that the second data (the anti-counterfeiting feature data in fig. 2) can also carry other product anti-counterfeiting feature information, such as the encoded information of the RFID tag embedded in the artwork entity, etc., based on actual needs.
Then, step S220 is performed, and an intelligent contract is deployed on the blockchain platform based on the product description data to create and generate a non-homogeneous certificate corresponding to the artwork entity, where the intelligent contract has a function of adding a property change record on a contract object;
since the data size of the first data and the second data is generally large (for example, the first data and the second data carrying the 3D scan information in this embodiment), in order to facilitate the deployment of the intelligent contract on the blockchain platform, in step S220, the intelligent contract is deployed on the blockchain platform based on the product description data, and the intelligent contract may be deployed on the blockchain platform according to the metadata of the product description data;
specifically, for convenience of implementation, in this embodiment, the first data and the second data are respectively subjected to hash processing, and a first hash value and a second hash value are correspondingly obtained (as shown in fig. 2, the first hash value and the second hash value correspond to the product fingerprint in fig. 2); and carrying out intelligent contract deployment according to the first hash value and the second hash value.
In addition, in practice, the artwork entity may belong to artwork manufactured by batch production, such as the aforementioned cloisonne vase, and in order to implement traceability management of the full life cycle, the product description data further includes third data for carrying product production and distribution information (the generation of the third data may be generated based on the input related information of the user);
for example, the product production release information includes product source information (including artist information, manufacturer information, copyright information, and the like), product release total amount and release number information, and default owner information. At this time, in an actual implementation, the intelligent contract deployment is 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 large, the third data may be stored in the relevant data platform, and the intelligent contract deployment may be 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 entities, corresponding ownership change is performed on the non-homogeneous voucher according to the intelligent contract based on the input of the user, and an ownership change record of the non-homogeneous voucher is generated, so that the source tracing management of the artwork entities is realized based on the historical ownership change record of the non-homogeneous voucher.
In this embodiment, in the process of transferring the entity of the art, based on the industry rule or the management rule of the transaction transfer, the transfer of the entity of the art must complete the ownership change of the corresponding non-homogenization voucher, and is regarded as a valid transfer.
How traceability management is implemented in the present application is described below.
Specifically, to implement the property change of the non-homogeneous voucher, in this embodiment, the intelligent contract is configured to:
the process of ownership change is initiated by the owner of the certificate and is confirmed and completed by the receiver of the certificate;
after the ownership is changed, signature information of both parties involved in the change is additionally recorded in the certificate (corresponding to the authentication flow information of the NFT in fig. 2).
It is easy to understand that, in order to implement the above configuration of the smart contract, both parties (or both parties of the transaction) that need to transfer the work of art entities are users of the blockchain platform, the NFT corresponding to the work of art entities is subjected to weight change on the blockchain platform, and signature information of both parties after the transaction is additionally recorded on the voucher (similar to 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 (who also correspondingly holds a corresponding non-homogeneous voucher on the blockchain platform) initiates an ownership change process of the non-homogeneous voucher, the system background first determines whether the initiation is initiated by an owner of the property right (i.e., whether the initiation is initiated by the owner of the property right), and then performs processing based on the process logic shown in fig. 3, and under the condition that the relevant rules of the intelligent contract are satisfied, the ownership change process is completed, and signature information of both parties after the transaction is additionally recorded on the voucher, so as to form an ownership change record.
Therefore, in each process, the above processes are carried out, and a non-homogeneous negotiable historical ownership change record is generated, and because the signature information of both transaction parties in each transaction change is recorded in the ownership change record, the traceability management of the artwork entity can be realized on the basis of inquiring the non-homogeneous negotiable historical ownership change record.
In addition, the circulation process of the artwork generally involves the identification link of the entity of the transferred artwork. 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 identifying the writing of information must be initiated by the certified owner;
after additionally recording the signature of the certification authority involved in the certification, the signature of the certifier, and the metadata of the certification conclusion on the certificate, the process of writing the certification information is completed.
In this embodiment, for example, the flow logic for writing authentication information is shown in fig. 4, and the written authentication information corresponds to the authentication flow information in fig. 2.
It is easily understood that in the practical implementation of the authentication process, the related authenticator (which needs to have the related qualification authority) can obtain the product description data (such as the aforementioned first data and second data carrying the related 3D scanning information) of the artwork entity to be authenticated from the product fingerprint in NFT to the authentication data platform, and perform the 3D scanning again on the artwork entity to be traded by using the related technology means, and perform the authentication based on the comparison between the data obtained by the scanning and the product description data (such as the second data).
The technical scheme of the application is provided mainly for reducing the occurrence of counterfeiting behaviors, in the embodiment, the identification conclusion and the related information of the identification party are additionally recorded on the non-homogeneous general evidence, so that the traceable related information is further improved, the non-autonomous or illegal behaviors of the identification party are reduced, and the healthy development of the industry is facilitated.
