Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0020] The method provided in the embodiment of the present application can be implemented through alliance chain technology. The following is an introduction to the blockchain-based data intellectual property evidence tracing method provided in the embodiment of the present application. Among them, the data intellectual property evidence tracing system can be used as the execution subject of the method provided in the embodiment of the present application.

[0021] Figure 1 The following is a flow chart of a blockchain-based data intellectual property evidence tracing method provided by an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0022] Step S101, create a record node corresponding to the data intellectual property to be recorded and traced on the alliance chain.

[0023] In step S101, the evidence node is the object of tracking the evidence source. In the embodiment of the present application, the evidence node is an abstraction of data intellectual property rights. Among them, the evidence node is deployed on the alliance chain. The alliance chain is a blockchain used between institutions. It is only for members of a specific group and limited third parties. It specifies multiple pre-selected nodes as account keepers. The generation of each block is jointly determined by all pre-selected nodes.

[0024] Step S102, when the storage node corresponding to the data intellectual property to be stored and traced triggers the target registration node, the data intellectual property to be stored and traced is processed for title confirmation to obtain title confirmation information of the data intellectual property to be stored and traced.

[0025] In step S102, the target registration node is any one of the multiple registration nodes included in the traceability program, and the ownership information at least includes the asset ownership object of the data intellectual property to be traced and the asset flow data of the data intellectual property to be traced under the target registration node.

[0026] In step S102, the registration node in the traceability program is deployed in the alliance chain. The traceability program is used to characterize the entire process of the data intellectual property transfer. Multiple registration nodes are deployed in the traceability program. Each business stage cannot exist independently and must be attached to the traceability program. In an embodiment of the present application, the specific location of the registration node in the traceability program can be deployed according to the business logic. The flow attributes corresponding to each registration node include at least: the asset ownership object of the data intellectual property to be traced and the asset transfer information in the corresponding registration node (for example, the transfer time of the data intellectual property, the transfer object of the data intellectual property, the transfer amount of the data intellectual property, etc.).

[0027] Step S103, record the ownership information of the data intellectual property to be recorded and traced under the target registration node in the asset transfer field in the alliance chain.

[0028] In step S103, the asset transfer field is used to record the transfer attributes corresponding to the data intellectual property to be recorded and traced in each registration node included in the traceability program. That is, in the embodiment of the present application, when the data intellectual property to be recorded and traced circulates in the alliance chain, each time it passes through a registration node, the data intellectual property record traceability system will add the transfer attributes corresponding to the registration node to the asset transfer field of the data intellectual property to be recorded and traced.

[0029] Step S104, receiving an asset evidence tracing request, obtaining the asset identifier corresponding to the data intellectual property to be evidenced and traced from the asset evidence tracing request, and reading the asset transfer field corresponding to the asset identifier from the alliance chain.

[0030] In step S104, the asset evidence tracing request includes the asset identifier corresponding to the data intellectual property to be evidenced and traced. In the embodiment of the present application, different data intellectual property rights have different asset identifiers. When the user needs to perform evidence tracing on the data intellectual property, the unique asset identifier of the data intellectual property to be evidenced and traced can be input into the data intellectual property evidence tracing system, so that the asset evidence tracing request can perform evidence tracing on the data intellectual property to be evidenced and traced according to the asset identifier of the data intellectual property to be evidenced and traced.

[0031] Step S105, based on the asset ownership object and asset transfer information corresponding to the asset transfer field, determine the evidence traceability information of the data intellectual property rights to be traced.

[0032] In step S105, since the asset flow field records the flow properties of the data intellectual property rights to be traced at each registration node, when it is necessary to trace the data intellectual property rights to be traced, the data intellectual property rights traceability system can directly read the asset flow field of the data intellectual property rights to be traced, and can obtain the asset ownership object and asset flow status of the data intellectual property rights to be traced at each registration node, which not only realizes the traceability of the asset ownership object, but also realizes the traceability of the asset flow status, that is, realizes the full-process traceability of the data intellectual property rights to be traced.

[0033] Based on the scheme defined by the above steps S101 to S105, it can be known that in the embodiment of the present application, since the resource evidence traceability field records the flow properties of the data intellectual property to be evidenced and traced when it flows through each registration node, when the user needs to view the evidence traceability information of the data intellectual property to be evidenced and traced, it is sufficient to directly obtain the information contained in the asset flow field, which simplifies the operational steps of data intellectual property evidence traceability and improves the efficiency of data intellectual property evidence traceability.

[0034] In the embodiment of the present application, the flow attributes of each registration node include the asset ownership object and the asset flow information, which is the information obtained by confirmation of ownership. That is, in the embodiment of the present application, in the process of data intellectual property circulation, the data intellectual property is confirmed, which reduces the difficulty of data intellectual property storage and traceability, thereby improving the efficiency of data intellectual property storage and traceability.

[0035] The following is an explanation of each step of the method provided in the embodiments of the present application.

[0036] In an embodiment of the present application, a storage and traceability algorithm can be used to record relevant information in the process of data intellectual property transfer to facilitate the storage and traceability of the data intellectual property.

[0037] In one example, Figure 2 The flowchart of the whole process of evidence tracing is shown. Figure 2 As shown, the process mainly includes the following steps:

[0038] Step S201, creating a traceability program in the alliance chain.

[0039] It should be noted that the realization of full-process evidence storage and traceability must start with the creation of a traceability program. After the traceability program is created, it is necessary to add a registration node to the traceability program. Among them, the creation of the traceability program and the addition of registration nodes are determined by business logic.

[0040] Step S202, creating a registration node in the alliance chain.

[0041] In an embodiment of the present application, a registration node is a node that the data intellectual property may pass through in the traceability program. In practical applications, the data intellectual property evidence traceability system can set the node attribute of each registration node, and the node attribute is used to characterize whether the registration node is a key node in the traceability program, wherein the key node is a registration node that the data intellectual property must pass through when it circulates in the traceability program. As an example, a "RegisterNode" field can be configured for the registration node, which is used to characterize whether the registration node is a key node in the traceability program. For example, if the attribute value corresponding to the "RegisterNode" field is "1" or "true", it indicates that the registration node is a key node; if the attribute value corresponding to the "RegisterNode" field is "0" or "false", it indicates that the registration node is a non-key node.

[0042] Step S203, adding the registration node to the traceability program.

[0043] In this step, in the process of creating a registration node, a traceability program can be configured for the data intellectual property, that is, the traceability program identifier can be configured for the process configuration field "TraceID" corresponding to the data intellectual property, so that the data intellectual property can be bound to the traceability program, and then the data intellectual property can flow in the traceability program. After configuring the traceability program for the data intellectual property, the registration node created in step S202 is added to the traceability program according to the business logic, so that the data intellectual property can flow in the registration node in the traceability program according to the business logic.

[0044] Step S204, create a proof node on the alliance chain.

[0045] Step S205, adding attribute information to the evidence storage node.

[0046] In step S205, the attribute information of the evidence node may include but is not limited to the name of the evidence node and the traceability program identifier. In one example, the user determines the traceability program of the process required by the evidence node by configuring the traceability program identifier field "RegTraceID" of the evidence node; and configures the name of the evidence node by configuring the evidence node name field "RegName" of the evidence node.

[0047] In addition, it should be noted that after creating the evidence node, if the relevant information of the evidence node needs to be modified (for example, the name of the evidence node, the traceability program to be circulated, etc.), the user can modify the attribute information of the evidence node by calling the relevant interface. If no modification is required, the evidence node can be placed in the traceability program, and the registration node in the traceability program can be called according to the business logic, and the flow attributes flowing through this registration node can be written into the asset flow field "IPRoamInform" of the data intellectual property.

[0048] Step S206: The data intellectual property rights are transferred through the evidence storage node in the registration node in the traceability program.

[0049] Step S207, query the full-process evidence traceability information of the evidence storage node.

[0050] After the evidence node calls the registration node in the traceability program, that is, after it circulates in the traceability program according to the business logic, the user can call the relevant interface to view the specific information of the evidence node flowing through each registration node. This specific information is the full-process evidence traceability information of the data intellectual property rights.

[0051] In the embodiment of the present application, digital watermarking is used to realize the confirmation of data intellectual property rights. Specifically, a preset digital watermark generation algorithm is used to generate a target digital watermark corresponding to the data intellectual property rights to be stored and traced; then, the target digital watermark is embedded in the data intellectual property rights to be stored and traced to obtain the converted data intellectual property rights to be stored and traced; then, the embedded information of the target digital watermark in the data intellectual property rights to be stored and traced is obtained, and based on the converted data intellectual property rights to be stored and traced and the embedded information, the confirmation information of the data intellectual property rights to be stored and traced is determined.

[0052] In the above embodiment, the embedding information at least includes generation parameters and embedding position of the target digital watermark, wherein the target digital watermark may be a fragile digital watermark.

[0053] It should be noted that digital watermarking refers to embedding specific information into a digital signal, where the digital signal can be a picture, audio or video, etc. If a signal with a digital watermark is to be copied, the embedded information will also be copied. Digital watermarks can be divided into two types: emergent and hidden. Among them, emergent watermarks are visible watermarks, and the information contained in them can be seen at the same time when watching pictures or videos; hidden watermarks are added to audio, pictures or videos in the form of digital data, but are usually invisible. Hidden watermarks can be used to protect copyrights. By using hidden watermarks, unauthorized copying and copying of digital media can be avoided or prevented. Fragile watermarks can be implemented in hidden watermarks, where fragile watermarks are a technology used to confirm rights and protect file integrity. Fragile watermarks are different from other watermark technologies. They can not only detect whether a file has been tampered with, but also determine the modification location of the file. In the embodiment of the present application, fragile watermarks are used to realize the confirmation of data intellectual property rights.

[0054] In one example, a method for confirming data intellectual property rights using fragile watermarks may include the following steps:

[0055] Step S31, selecting a fragile watermark algorithm.

[0056] Step S31, selecting a fragile watermark algorithm.

[0057] Step S32: Generate a fragile watermark.

[0058] The fragile watermark algorithm selected is used to generate a fragile watermark of the data intellectual property. The fragile watermark is usually some hidden data or mark that can be embedded in the data intellectual property.

[0059] Step S33: embedding a fragile watermark.

[0060] The generated fragile watermark is embedded into the data intellectual property. This process usually modifies the bits or content of the data intellectual property, but should not significantly affect the readability or usability of the data intellectual property.

[0061] Step S34, recording fragile watermark information (ie, embedded information), wherein the fragile watermark information includes but is not limited to generation parameters and position of the fragile watermark.

[0062] Step S35, transmitting or distributing the data intellectual property, in which the data intellectual property with the fragile watermark is transmitted to other people or distributed to the target audience.

[0063] Step S36, checking the integrity of the data intellectual property.

[0064] In this step, the receiver of the data intellectual property can use the fragile watermark algorithm to check the integrity of the data intellectual property and whether it has been tampered with. If the data intellectual property has been tampered with, the fragile watermark algorithm can indicate the modification position of the file.

[0065] This completes the explanation of the method provided in the embodiments of the present application.

[0066] From the above content, it can be seen that the method provided in this application can realize the full-process evidence storage and traceability of data intellectual property rights based on the alliance chain, solve the problems of data intellectual property rights confirmation, evidence storage, traceability and circulation, make data intellectual property rights more secure and reliable, and in complex circulation, the full-process circulation status of data intellectual property rights can be obtained through the interface with one click.

[0067] In order to solve the problem of lack of confirmation mechanism for data intellectual property rights, the solution provided by the embodiment of the present application uses fragile digital technology to add fragile watermarks to data intellectual property rights, which will show the owner of the data intellectual property rights. If the data intellectual property rights are modified, the fragile watermark will become invalid and unreadable. This function also ensures the integrity of the data intellectual property rights.

[0068] In addition, the solution provided in the embodiment of the present application is implemented through a consortium chain, which enables the data intellectual property evidence storage and traceability system to have higher performance, improves the processing capability of data calculation, and thereby improves the efficiency of data intellectual property evidence storage and traceability.

[0069] Finally, enterprises store a large amount of data, and there is data with low data sensitivity but very valuable. These data form data intellectual property rights that can be circulated in the market to maximize the value of the data, bring benefits to the enterprise, and bring innovative ideas to the entire industry or other industries. The solution provided by the embodiment of the present application can also be used to solve the problems of data source fraud, low data content quality, easy data leakage, difficulty in data confirmation, and single data access rights when data intellectual property rights are circulated.

[0070] The present application also provides a data intellectual property evidence tracing device, such as Figure 3 As shown, the device 300 includes: a blockchain node creation module 301, a data intellectual property rights confirmation module 302, a data intellectual property rights registration module 303, a data intellectual property rights verification module 304 and a data intellectual property rights tracing module 305.

[0071] Create a blockchain node module 301, which is used to create a storage node corresponding to the data intellectual property rights to be stored and traced on the alliance chain;

[0072] The data intellectual property rights confirmation module 302 is used to use a digital watermark to confirm the data intellectual property rights to be stored and traced when the storage node corresponding to the data intellectual property rights to be stored and traced triggers the target registration node, and obtain the confirmation information of the data intellectual property rights to be stored and traced. Specifically, a preset digital watermark generation algorithm is used to generate a target digital watermark corresponding to the data intellectual property rights to be stored and traced; the target digital watermark is embedded in the data intellectual property rights to be stored and traced to obtain the converted data intellectual property rights to be stored and traced; the embedded information of the target digital watermark in the data intellectual property rights to be stored and traced is obtained, and the embedded information at least includes the generation parameters and the embedding position of the target digital watermark; based on the converted data intellectual property rights to be stored and traced and the embedded information, the confirmation information of the data intellectual property rights to be stored and traced is determined. Among them, the target registration node is any one of the multiple registration nodes contained in the traceability program, and the confirmation information at least includes the asset ownership object of the data intellectual property rights to be stored and traced and the asset flow data of the data intellectual property rights to be stored and traced under the target registration node. The registration nodes in the traceability program are deployed in the alliance chain;

[0073] The data intellectual property registration module 303 is used to record the confirmation information of the data intellectual property to be recorded and traced under the target registration node in the asset transfer field in the alliance chain, wherein the asset transfer field is used to record the transfer attributes corresponding to the data intellectual property to be recorded and traced in each registration node included in the traceability program;

[0074] The data intellectual property verification module 304 is used to receive an asset evidence tracing request, obtain the asset identifier corresponding to the data intellectual property to be evidenced and traced from the asset evidence tracing request, and read the asset transfer field corresponding to the asset identifier from the alliance chain;

[0075] The data intellectual property tracing module 305 is used to determine the evidence tracing information of the data intellectual property to be traced based on the asset ownership object and asset transfer information corresponding to the asset transfer field.

[0076] In one example, the data intellectual property evidence storage and traceability device also includes: a node name determination module, which performs a secure hash calculation on the account information of the asset ownership object to which the data intellectual property to be evidenced and traced belongs under the target registration node, obtains the calculation result, and determines the calculation result as the name of the evidence node.
