Fig. 2 is a first flowchart of a processing method for blockchain-based traceability information according to one or more embodiments of the present disclosure, where the method in fig. 2 can be executed by the digital property right server in fig. 1, as shown in fig. 2, and the method at least includes the following steps:

s202, receiving a processing request aiming at the non-homogenization attribute information of the target object; the non-homogenization attribute information is generated based on related historical events of the target object, and first source tracing information generated aiming at the certified historical events of the target object is stored in the block chain system; the processing request of the non-homogenization attribute information carries material evidence code information of the target object and processing description information of the non-homogenization attribute, wherein the processing description information comprises registration description information or change description information, and the material evidence code information is unique identification information of the target object;

the target object can be a physical commodity which realizes personalized value increase due to non-homogeneity attribute addition or change during the holding period of at least one object right holder, for example, the target object can be at least one of a commodity, an artwork, a collection and a historical building with cultural characteristics, the non-homogeneity attribute information can be non-inherent attribute information aiming at addition or modification of the target object by the non-initial object right holder in the transfer and circulation process of the target object, and the related historical events can be historical events occurring aiming at addition or change of the non-homogeneity attribute of the target object, for example, at least one of a star signature, a celebrity seal and expert authentication; the method comprises the following steps of (1) signing a star on mass-produced clothes, or stamping a celebrity on mass-prepared calligraphy and painting, or attaching expert identification and authentication information to a certain collection; correspondingly, the homogeneity attribute of the target object refers to inherent attribute information of the target object in the production process, and the inherent attribute information of a plurality of target objects in the same batch has no essential difference, such as at least one of manufacturer name, object model, object color and object size.

Specifically, after the current ownership holder adds or changes the non-homogenization attribute of the target item in the transfer and circulation process of the target item, a processing request for the non-homogenization attribute information of the target item is sent to the digital ownership server based on the trigger operation of the current ownership user, wherein the processing request includes a registration request or a change request.

And S204, based on the non-homogenization attribute information, generating attribute record information of the non-homogenization attribute of the target object through a block chain system, associating second tracing information obtained based on the attribute record information with first tracing information and storing the second tracing information and the first tracing information in the block chain system, wherein the second tracing information is used for credibly tracing the generation of the non-homogenization attribute information of the target object and related events, and the first tracing information is used for credibly tracing certified historical events and related information which occur before the historical events to be certified related to the non-homogenization attribute information.

The attribute recording information of the non-homogeneous attribute may include: at least one item of material evidence code information of the target object, identification information of a processing requester of the non-homogenization attribute information, processing description information of the non-homogenization attribute information, and related historical event occurrence time information of the non-homogenization attribute information; specifically, the attribute recording information of the non-homogeneous attribute may be directly determined as the second tracing information, or the second tracing information may be generated based on the attribute recording information of the non-homogeneous attribute and related additional information, where the related additional information may be event occurrence evidence information related to a historical event that generates the non-homogeneous attribute information and is uploaded by the processing requester, or event related information related to the historical event that generates the non-homogeneous attribute information and is automatically acquired by the block chain system;

specifically, the digital property right server receives a processing request of non-homogenization attribute information of a target article sent by a property right holder, initiates a corresponding non-homogenization attribute record generation request to the blockchain system, automatically generates attribute record information of the non-homogenization attribute of the target article by calling an intelligent contract deployed in the blockchain system, and stores second traceability information obtained based on the attribute record information in the blockchain system, wherein when traceability information is stored for the target article in the blockchain system, a full-scale storage mode or an incremental storage mode can be adopted, and since the second traceability information and first traceability information stored in the blockchain system for the target article in advance can both contain an article unique identifier (such as evidence code information) of the target article, the second traceability information and the first traceability information are stored in the blockchain system in an associated manner, that is, all the tracing information stored for the target item is queried in the blockchain system based on the unique identifier of the target item.

In one or more embodiments of the present specification, a traceability information record of a target item is extended to a multiple transfer and circulation process of the target item, in the transfer and circulation process of the target item, a server responds to a processing request of a right holder for each non-homogenization attribute information of the target item, the server responds to a processing request of the non-homogenization attribute information of the target item, generates attribute record information of the non-homogenization attribute of the target item through a block chain system, realizes a trusted record for registration or change operation of the non-homogenization attribute of the target item, associates and stores traceability information obtained based on the attribute record information of the non-homogenization attribute and previously recorded source information of the target item in the block chain system, thereby realizing that on the premise of satisfying an individual requirement of the right holder for registration or change of the non-homogenization attribute of the target item, the credible tracing of each processing request aiming at the non-homogenization attribute information of the target object can be ensured, and the comprehensiveness and integrity of the tracing information stored aiming at the target object in the block chain system are also ensured.

Further, in order to ensure the registration or the alteration authenticity and the credibility of the non-homogenization attribute information of the target article, the method for verifying the authenticity of the newly added non-homogenization attribute information or the updated non-homogenization attribute information of the target article is added, as shown in fig. 3, in S204, based on the non-homogenization attribute information, the block chain system generates attribute record information of the non-homogenization attribute of the target article, and associates second traceability information obtained based on the attribute record information with the first traceability information and stores the second traceability information in the block chain system, which specifically includes:

s2042, performing credibility verification on the non-homogenization attribute information through a block chain system to obtain a corresponding credibility verification result;

For another example, the related historical event of the non-homogenization attribute information to be processed is expert identification and authentication, correspondingly, the event related information may be an identification certificate number and a production time applied to be produced by an identification expert in the occurrence time period of the related historical event, and the processing specification information may include: certificate identification and authentication time; specifically, the identification certificate number and the production time in the event-related information are correspondingly compared with the certificate identifier and the identification time in the processing instruction information, and if the authentication identifier and the time are both matched, the credibility verification result is determined to be passed.

Specifically, for the credibility verification process of the non-homogeneous attribute information, the event occurrence evidence information of the relevant historical event that is uploaded by the processing request party and generates the non-homogeneous attribute information may be referred to, and correspondingly, the processing request carries the event occurrence evidence information of the relevant historical event, specifically, in step S2042, the credibility verification is performed on the non-homogeneous attribute information through the block chain system to obtain a corresponding credibility verification result, which specifically includes:

based on the event occurrence evidence information carried in the processing request, performing credibility verification on the non-homogenization attribute information to obtain a corresponding credibility verification result; the event occurrence evidence information may be video information of a generation process of non-homogeneity attribute information for the target object, or image information of a generation key node of the non-homogeneity attribute information for the target object.

In a specific implementation, in order to improve the accuracy of the credibility verification of the non-homogeneous attribute information, for the credibility verification process of the non-homogeneous attribute information, the automatically acquired event-related information and the event occurrence evidence information of the related historical event that is uploaded by the processing request party and generates the non-homogeneous attribute information may be referred to at the same time, specifically, in step S2042, the credibility verification is performed on the non-homogeneous attribute information through the block chain system to obtain a corresponding credibility verification result, which specifically includes:

acquiring event associated information corresponding to a related historical event of the non-homogenization attribute information;

and secondly, performing credibility verification on the non-homogenization attribute information based on the acquired event correlation information and the event occurrence evidence information carried in the processing request to obtain a corresponding credibility verification result.

Specifically, if both a first verification result obtained based on the event-related information and a second verification result obtained based on the event occurrence evidence information are credibility verifications, it is determined that the credibility verification for the non-homogenization attribute information of the target item passes.

Further, in order to improve the new addition or change controllability of the non-homogenization attribute information of the target object, a link of verifying whether the processing requester is the current owner of the target object is added, and only if the processing requester is determined to be the real owner, the received processing request of the non-homogenization attribute information is responded, and on the basis, the processing request of the non-homogenization attribute information also carries at least one of identification information of the processing requester, object weight code information of the target object and material evidence code information;

correspondingly, in the step S204, based on the non-homogenization attribute information, the attribute record information of the non-homogenization attribute of the target article is generated by the blockchain system, and the second tracing information obtained based on the attribute record information and the first tracing information are stored in the blockchain system in an associated manner, which specifically includes:

acquiring the property right attribution record information corresponding to the material evidence code information carried in the processing request through a block chain system; the property right attribution record information can be the property right attribution record information stored in the property right transfer aiming at the target object;

judging whether the processing request party is the current property right holder of the target object or not based on the acquired property right attribution record information, the identification information of the processing request party and/or the property right code information carried in the processing request;

specifically, the block chain system automatically judges whether the identification information of the processing requester carried in the processing request is consistent with the identification information of the current property right holder in the property right attribution record information based on the acquired property right attribution record information, and if so, determines that the processing requester is the current property right holder of the target article; or, based on the acquired property right attribution record information, judging whether the property right code information carried in the processing request is consistent with the updated property right code information in the property right attribution record information, if so, determining that the processing request party is the current property right holder of the target article; or, based on the acquired property right attribution record information, judging whether the identification information of the processing request party carried in the processing request is consistent with the identification information of the current property right holder in the property right attribution record information, and judging whether the property right code information carried in the processing request is consistent with the updated property right code information in the property right attribution record information, if yes, determining that the processing request party is the current property right holder of the target article.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (core universal Programming Language), HDCal, jhddl (Java Hardware Description Language), Lava, Lola, HDL, PALASM, rhyd (Hardware Description Language), and vhigh-Language (Hardware Description Language), which is currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
