Specifically, in consideration of the non-tamper-proof property of the information stored in the block chain system, updated article code information and/or at least one piece of property right attribution record information is stored in the block chain system for each property right transfer of the target article, so that when corresponding business processing (for example, physical object extraction processing or property right verification) is performed on the basis of the article code information and/or the property right attribution record information stored in the block chain system in the following, in order to identify the validity of the property right attribution information acquired from the block chain system, based on this, the digital property right server generates updated property right attribution record information on the basis of the property right code information of the target article, the identification information of the property right transfer party and the updated property right code information; and storing a corresponding relation between the property right attribution record information and the information state parameter, wherein the information state parameter corresponding to the property right attribution record information before updating is in a logout state, and the information state parameter of the property right attribution record information after updating is in an effective state, so that the digital property right service end can determine the effectiveness of the property right attribution record information acquired from the block chain system based on the corresponding relation, and further determine the current property right holder of the target object based on the currently effective property right attribution record information. In specific implementation, the correspondence between the ownership record information and the information state parameter may be stored in the blockchain system, may also be stored locally at the digital ownership server, and may also be stored locally at the digital ownership server and in the blockchain system.
In addition, in order to identify the validity of the property right attribution information acquired from the blockchain system, when updated property right attribution record information is stored in the blockchain system, time stamp information corresponding to the property right attribution record information is stored, so that the digital property right server can determine the validity of the property right attribution record information acquired from the blockchain system based on the time stamp information, wherein the latest property right attribution record information with the time stamp is valid information, and further determine the current property right holding party of the target object based on the currently valid property right attribution record information. In a specific implementation, the time stamp information may be added as an information field to the ownership record information.
In one or more embodiments of the present description, in a circulation process of a target article, for each property right transfer process of the target article, an updated article code information is automatically determined by using a blockchain system and stored in a blockchain, and updated property right attribution record information is stored in the blockchain system based on the updated article code information, so that a user holding the latest property right code information is an owner of an entity product corresponding to the property right code information, thereby realizing definition of the property right attribution of the target article in the circulation process; in addition, in the circulation process of the target article, the material evidence code information for uniquely identifying the target article and the material weight code information changing along with the material weight transfer of the target article are used, so that the entity commodity does not need to participate in an assignment link in the circulation process, and a final material weight holder of the target article can directly extract corresponding entity commodity from a commodity production source based on the material evidence code information and the latest material weight code information, so that the authenticity of the entity commodity obtained by the final material weight holder is ensured, and the purpose of entity commodity fidelity is further achieved.
Specifically, in step S804, determining updated item code information of the target item through the blockchain system based on the identification information of the right-to-transfer party, specifically includes:

and determining updated object code information of the target object based on the updated object weight code information and the object evidence code information of the target object.
Considering that a final property right holder of a target article may have a requirement for extracting the entity article after the entity article is circulated in the form of a digital asset, that is, after the target article is subjected to multiple property right transfers, at this time, the final property right holder may directly extract a corresponding entity article from an article production source based on property right code information held by the final property right holder, and based on this, after determining updated property right attribution record information of the target article and storing the record information in the block chain system based on the updated property right code information in the above S806, the method further includes:

Specifically, after generating new item code information through an intelligent contract deployed in a block chain system, namely generating updated item right code information for representing the physical right of a target item held by the item right transfer party, the digital item right server sends the updated item right code information to the item right transfer party, so that when the item right transfer party needs to extract the physical right, the updated item right code information can be used as a basis for extracting the physical right of the target item.
In the method, in consideration of the fact that multiple times of object right transfer can be performed on a target article in the process of circulating an entity commodity in a digital asset mode, an object right transfer-in party in an object right transfer node of the target article becomes an object right transfer-out party in a next object right transfer node, and therefore the object right transfer-in party in the object right transfer node also has the requirement of proving that the object right transfer-in party is a real holder of the target article to a next object right transfer party in the next object right transfer process, and updated object code information is sent to the object right transfer-in party.
Specifically, the digital property right server generates updated article code information and then automatically sends the updated article code information to the property right transfer party, or after receiving an article code acquisition request from the property right transfer party, sends the article code information generated for the property right transfer party to the corresponding property right transfer party, where the property right transfer party is the current property right holder of the target article.
Further, considering that there may be a case that the commodity transaction platform and the digital rights platform belong to different service platforms, and at this time, the digital rights server cannot control the suspension order selling process of the target item, so to ensure controllability of the rights transfer, by adding the right verification code information, the rights holder of the target item simultaneously holds the rights code information and the right verification code information, so that the rights holder can provide the right verification code information to the rights transfer party in the rights transfer node, thereby proving that the right verification code information is the true holder of the target item, correspondingly, the digital rights server further provides the services for verifying whether the rights transfer party is the true holder of the target item for the rights transfer party, and based on this, before receiving the rights transfer request for the target item in the above S802, the method further includes:

Specifically, the sending a feedback result of the ownership of the target object to the ownership transferring party based on the authentication code information carried in the ownership authentication request includes:
judging whether the authorization code information carried in the authorization verification request is a valid authorization code or not; specifically, whether article code information and/or article right attribution record information containing the authentication code information carried in the article right authentication request is stored in the block chain system or not is judged, and if yes, the authentication code information is determined to be an effective authentication code; in addition, considering that there may be a case where the right transfer party uses old right verification code information to deceive the right transfer party, after acquiring the item code information and/or the right attribution record information including the right verification code information, based on the correspondence between the right attribution record information and the information status parameter and/or the correspondence between the item code information and the information status parameter, it is determined whether the information status parameter of the acquired item code information and/or the right attribution record information is in a valid state, and if so, it is determined that the right verification code information is in a valid right verification code.
If the judgment result is negative, sending a property right attribution feedback result containing the failure prompt information of the weight verification code to the property right transfer party;
if the judgment result is yes, acquiring the identity identification information corresponding to the authentication code information from the block chain system; specifically, the object right attribution record information corresponding to the verification code information is obtained from the block chain system, and the identification information of the object right transfer party in the object right attribution record information is determined as the identification information of the real owner of the target object.
Sending an object right attribution feedback result generated based on the acquired identity identification information to the object right transfer party so that the object right transfer party can identify whether the object right transfer party is a real holder of the target object based on the identity identification information;
correspondingly, the step S802 of receiving the object right transfer request for the target object specifically includes:
and receiving a right transfer request sent by the right transfer party based on a feedback result of the right attribution for the target object, specifically, receiving a right transfer request sent by the right transfer party for the target object when the right transfer party is determined to be the real owner of the target object.
Specifically, when the target article is converted into the digital asset, material evidence code information, material right code information and verification right code information are generated for the target article by using an intelligent contract deployed in the block chain system; and in the process of circulating the target articles in the form of digital assets, destroying the property right code information and the verification weight code information held by the property right transfer-out party by using an intelligent contract deployed in the block chain system, generating new property right code information and verification weight code information for the property right transfer-in party, thereby not only realizing the purpose of defining the ownership of the target object in the circulation process, but also providing the service of verifying whether the ownership transferring party is the real holder of the target object for the ownership transferring party, thus, the object right transfer operation can be triggered after the object right transfer party of the object right transfer node is determined to be the real holding party of the target object, and the processes of generation, circulation and destruction of material evidence code information, material right code information and verification right code information are automatically executed by using an intelligent contract deployed in the block chain system, so that the safety control of the relevant code information of the target object is realized.
The receiving of the request for verifying the property right of the target object in the process of requesting the property right verification for the property right transfer party specifically includes:
receiving a property right verification request generated by a property right transfer party based on the verification code information input by a user through a target application; the right verifying code information is verification information which is provided by a right transferring party and used for verifying the right attribution of a target object; the target application comprises: access the applet or Html5 web page of the specified host application.

generating updated authorization code information corresponding to the updated object authorization code information based on the public key; specifically, the public key is determined as updated authorization code information corresponding to the updated object authorization code information.
Specifically, considering that the object right code information is used for proving that the target article belongs to the object right holder, the object right code information is only independently owned by the object right holder and is not disclosed to the outside, and the verification code information is verification information provided by the object right transfer-out direction and the object right transfer-in direction and used for verifying the object right of the target article, so the verification code information needs to be disclosed to the outside.
After the production link for the entity goods is completed, the entity goods may be converted into digital assets, so that the entity goods are circulated in a digital asset form, and based on this, before receiving the object right transfer request for the target object in the above S802, the method further includes:

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 making 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, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. 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, apparatuses, modules or units described in the above embodiments may be specifically implemented by a computer chip or an entity, or implemented 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.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately.

It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
