Fig. 2 is a first flowchart of a processing method of 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 rights server in fig. 1, and as shown in fig. 2, the method at least includes the following steps:

s202, receiving a processing request of non-homogeneous attribute information of a target object; wherein the non-homogeneous attribute information is generated based on a related historical event of the target object, and first traceability information generated for the stored historical event of the target object is stored in the blockchain system; the processing request of the non-homogeneous attribute information carries material evidence code information of the target object and processing description information of the non-homogeneous 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 may be an entity commodity which realizes personalized increment due to new or change of non-homogeneous attribute of at least one object right holder, for example, the target object may be at least one of commodity, artwork, collection and historical building with cultural characteristics, the non-homogeneous attribute information may be non-inherent attribute information of new or modified target object by a non-initial object right holder in the transferring and circulation process of the target object, and the related historical event may be at least one of a star signature, celebrity seal and expert authentication for the new or changed non-homogeneous attribute of the target object; namely, star signatures on mass-produced clothes, or celebrities on mass-prepared calligraphy and painting are stamped, or expert authentication information is attached to a certain collection; correspondingly, the homogenizing property of the target object refers to intrinsic property information of the target object in the production process, and intrinsic property information of a plurality of target objects in the same batch does not have intrinsic differences, for example, at least one of manufacturer name, object model, object color and object size.

Specifically, after the current object right holder newly adds or changes the non-homogeneous attribute of the target object in the transfer circulation process of the target object, a processing request of non-homogeneous attribute information of the target object is sent to the digital object right server based on the triggering operation of the current holder, wherein the processing request comprises a registration request or a change request.

S204, based on the non-homogeneous attribute information, generating attribute record information of the non-homogeneous attribute of the target object through a blockchain system, and storing second tracing information obtained based on the attribute record information and first tracing information in the blockchain system in a correlated mode, wherein the second tracing information is used for carrying out trusted tracing on generation of the non-homogeneous attribute information of the target object and related events, and the first tracing information is used for carrying out trusted tracing on stored historical events and related information which occur before a to-be-stored historical event related to the non-homogeneous attribute information.

Wherein, the attribute record information of the non-homogeneous attribute may include: at least one item of physical evidence code information of a target object, identification information of a processing requester of 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 record information of the non-homogeneous attribute can be directly determined as the second tracing information, the second tracing information can be generated based on the attribute record information of the non-homogeneous attribute and related additional information, and the related additional information can be event occurrence evidence information related to a historical event for generating the non-homogeneous attribute information uploaded by a processing requester, or event related information related to the historical event for generating the non-homogeneous attribute information, which is automatically acquired by a blockchain system;

Specifically, the digital object right server receives a processing request of non-homogeneous attribute information of a target object sent by an object right holder, initiates a corresponding non-homogeneous attribute record generation request to the blockchain system, automatically generates attribute record information of non-homogeneous attribute of the target object 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 the traceability information of the target object is stored in the blockchain system, a full-scale storage mode can be adopted, and an incremental storage mode can also be adopted, and because the second traceability information and the first traceability information which is stored in the blockchain system for the target object in advance can both contain the unique identification (such as the object evidence code information) of the object, the second traceability information and the first traceability information are stored in the blockchain system in an associated mode, namely, all the traceability information stored for the target object is queried based on the unique identification of the target object in the blockchain system.

In one or more embodiments of the present disclosure, a trace information record of a target object is extended to a multiple transfer circulation process of the target object, in the transfer circulation process of the target object, a server responds to a processing request of an object right holder for each time of non-homogeneous attribute information of the target object, the server generates attribute record information of the non-homogeneous attribute of the target object through a blockchain system based on the processing request of the non-homogeneous attribute information of the target object, so as to perform trusted recording on registration or change operation of the non-homogeneous attribute of the target object, and store trace information obtained based on the attribute record information of the non-homogeneous attribute and trace information recorded in advance in the blockchain system in an associated manner, thereby ensuring that the subsequent processing request of the non-homogeneous attribute information of the target object can be reliably traced on the premise of meeting the personalized requirement of the object right holder for the non-homogeneous attribute registration or change of the target object, and ensuring comprehensive trace and integrity of source information stored in the blockchain system for the target object.

Further, in order to ensure the authenticity and the reliability of registration or change of the non-homogeneous attribute information of the target object, the authenticity of the newly added non-homogeneous attribute information or the updated non-homogeneous attribute information of the target object is additionally verified, based on which, as shown in fig. 3, the step S204 generates attribute record information of the non-homogeneous attribute of the target object by the blockchain system based on the non-homogeneous attribute information, and associates and stores second trace information obtained based on the attribute record information with the first trace information in the blockchain system, specifically including:

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

s2044, determining whether the credibility verification result obtained based on the non-homogeneous attribute information is verification passing;

if the credibility verification result is passed, S2046, based on the non-homogeneous attribute information, generating attribute record information of the non-homogeneous attribute of the target object through the blockchain system, and storing second tracing information obtained based on the attribute record information and the first tracing information in association with each other in the blockchain system;

If the credibility verification result is not passed, S2048 sends a credibility verification failure prompt message of the non-homogenous attribute information to the processing requester of the non-homogenous attribute information.

Specifically, for the credibility verification process of the non-homogeneous attribute information, reference may be made to event association information of a relevant historical event that generates the non-homogeneous attribute information and is automatically acquired by a server or a blockchain system, and the processing request carries event identification information of the relevant historical event, specifically, S2042 performs credibility verification on the non-homogeneous attribute information through the blockchain system to obtain a corresponding credibility verification result, and specifically includes:

step one, acquiring event association information corresponding to a relevant historical event of the heterogeneous attribute information; the event association information may be obtained from a third party mechanism based on the event identification information of the related historical event, or may be obtained from a blockchain system based on the event identification information of the related historical event;

for example, the relevant historical event of the non-homogeneous attribute information to be processed is a star signature, and the corresponding event-related information may be travel information of the processing requester and/or signature star in an occurrence period of the relevant historical event; for another example, the relevant historical event of the non-homogeneous attribute information to be processed is expert authentication, and the corresponding event association information may be an authentication certificate number and a production time of the authentication expert applied for producing in the occurrence time period of the relevant historical event.

And secondly, carrying out credibility verification on the non-homogeneous attribute information based on the acquired event association information to obtain a corresponding credibility verification result.

The processing request of the non-homogeneous attribute information carries the material evidence code information of the target object and the processing description information of the non-homogeneous attribute, specifically, the acquired event associated information is compared with the processing description information, and the credibility verification result of the non-homogeneous attribute information is determined according to the information comparison result.

For example, the relevant historical event of the non-homogeneous attribute information to be processed is a star signature, the corresponding event related information may be travel information of the processing requester and/or signature star in an occurrence period of the relevant historical event, and the processing specification information may include: signature place information and signature time information; specifically, the position information and the time information in the journey information are correspondingly compared with the signature place information and the signature time information in the processing description information, and if the time and the place are matched, the credibility verification result is determined to be passed.

As another example, the relevant historical event of the non-homogeneous attribute information to be processed is expert authentication, and the corresponding event related information may be an authentication certificate number and a production time of the authentication expert applied to produce in the occurrence time period of the relevant 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 identification and the identification time in the processing description information, and if the identification and the time are matched, the credibility verification result is determined to be passed.

Specifically, for the credibility verification process of the non-homogeneous attribute information, reference may also be made to event occurrence evidence information of a relevant historical event that generates the non-homogeneous attribute information and is uploaded by the processing request party, and the processing request carries the event occurrence evidence information of the relevant historical event, specifically, S2042 performs credibility verification on the non-homogeneous attribute information through the blockchain system to obtain a corresponding credibility verification result, and specifically includes:

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

In a specific implementation, in order to improve accuracy of the reliability verification of the non-homogeneous attribute information, for the reliability verification process of the non-homogeneous attribute information, the automatically acquired event association information and the event occurrence evidence information of the relevant historical event which generates the non-homogeneous attribute information and is uploaded by the processing requester may be referred to simultaneously, and specifically, S2042 performs the reliability verification on the non-homogeneous attribute information through the blockchain system to obtain a corresponding reliability verification result, where the specific steps include:

Step one, acquiring event association information corresponding to a relevant historical event of the heterogeneous attribute information;

and secondly, carrying out credibility verification on the non-homogeneous attribute information based on the acquired event association information and the event occurrence evidence information carried in the processing request, and obtaining a corresponding credibility verification result.

Specifically, if the first verification result obtained based on the event-related information and the second verification result obtained based on the event occurrence evidence information are both the credibility verification pass, determining that the credibility verification of the non-homogeneous attribute information of the target object passes.

Further, in order to improve the controllability of new or changing of the non-homogeneous attribute information of the target object, a link for verifying whether the processing request party is the current object right holder of the target object is added, and only if the processing request party is determined to be the real object right holder, the received processing request of the non-homogeneous attribute information is responded, based on the processing request of the non-homogeneous attribute information, at least one of identification information of the processing request party, object right code information of the target object and object evidence code information is carried;

correspondingly, the step S204 of generating attribute record information of the non-homogeneous attribute of the target object by the blockchain system based on the non-homogeneous attribute information, and storing second tracing information obtained based on the attribute record information and the first tracing information in association with each other in the blockchain system, includes:

Acquiring object weight attribution record information corresponding to the object evidence code information carried in the processing request through a block chain system; the object right attribution record information can be object right attribution record information stored for object right transfer of a target object;

judging whether the processing request party is the current object right holder of the target object based on the acquired object right attribution record information, the identification information of the processing request party and/or the object right code information carried in the processing request;

specifically, the blockchain system automatically judges whether the identification information of the processing request party carried in the processing request is consistent with the identification information of the current object right holder in the object right attribution record information based on the acquired object right attribution record information, and if so, the processing request party is determined to be the current object right holder of the target object; or based on the acquired object weight attribution record information, judging whether the object weight code information carried in the processing request is consistent with updated object weight code information in the object weight attribution record information, if so, determining that the processing request party is the current object weight holder of the target object; or based on the acquired object right 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 object right holder in the object right record information, judging whether the object right code information carried in the processing request is consistent with the updated object right code information in the object right record information, and if so, determining that the processing request party is the current object right holder of the target object.

If the judgment result is yes, generating attribute record information of the non-homogeneous attribute of the target object through the blockchain system based on the non-homogeneous attribute information, and storing second tracing information obtained based on the attribute record information and the first tracing information in a related mode in the blockchain system;

if the judging result is negative, sending a processing request failure prompt message of the non-homogeneous attribute information to a processing request party of the non-homogeneous attribute information.

For each transfer of the object weight of the target object, since the current object weight information of the target object changes with the change of the object weight information, the updated object weight information is acquired for each transfer of the object weight, and based on this, as shown in fig. 6, the step S210 of acquiring the updated object weight information of the target object specifically includes:

The foregoing describes specific embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can 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 are also possible or may be advantageous.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of 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, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, 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 of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, 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.
