Detailed ways

The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the related invention, but not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that the embodiments of the present disclosure and the features of the embodiments may be combined with each other under the condition of no conflict. The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

FIG. 1 illustrates an exemplary system architecture of an embodiment of a method for managing detection information or an apparatus for managing detection information to which the present disclosure may be applied.

Data provider equipment (including deliverer equipment and participant equipment, participant equipment can be processor equipment, detector equipment, experts, etc.) & data consumers (such as client), regulatory authorities, CA agencies, users and other participants The devices jointly form a consortium chain.

Among them, participating enterprises can choose to deploy consensus nodes or node clusters to store the full amount of data on the blockchain according to their own needs, or choose to communicate directly with the consensus node gateways deployed by other enterprises through the client. Users communicate directly with the consensus node gateways deployed by other enterprises through the client.

The whole scheme involves four types of participating roles, namely:

Data provider equipment: The data provider equipment is the original data holder. It collects and uploads material data or data summary information in the form of blockchain smart contracts. Realize the business logic of data processing and data asset management; store on-chain data in database clusters mounted on consensus nodes to ensure massive data storage and potential on-chain data elastic expansion requirements; at the same time use the data services provided by the blockchain framework Function, through the installation of data service components, to achieve penetrating retrieval, statistical summary and other functions of data on the chain. Provide services to client-side upper-layer applications through public/private gateway nodes.

Data consumer: The data consumer is the data requester device of the original data, and can choose to deploy the consensus node or obtain data information from the data provider device consensus node only through the public/private gateway node

Regulatory agency: Regulatory agencies supervise on-chain data transaction exchange and traceability activities, deploy consensus nodes to hold consistent ledgers, and conduct real-time supervision of on-chain data usage logs, on-chain data transaction exchange history and other information through gateway nodes.

CA organization: The CA organization assigns a digital identity to each participant on the blockchain, and provides basic information for data confirmation and authority management verification on the chain.

Note: Delivering equipment, processing/inspecting equipment and other enterprises will switch between data provider equipment and data consumer roles in different links of the business process.

The deliverer's equipment provides catalogs for the available material testing and preparation services, and uploads the catalogs to the chain. The catalog structure is shown in Figures 3a and 3b. Users are subdivided according to their own industries of processing and testing materials, under the corresponding catalog path. Submit your own testing requirements.

Continuing to refer to FIG. 2 , a flow 200 of an embodiment in which the method for managing detection information according to the present disclosure is applied to a deliverer device is shown. The method for managing detection information includes the following steps:

Step 201 , in response to detecting a detection requirement submitted by a user terminal in a predetermined directory of the blockchain, a detection scheme is determined according to the detection requirement.

In this embodiment, the execution body of the method for managing detection information (for example, the delivery device in the data provider device shown in FIG. 1 ) can catalog the material detection and preparation services that it can provide, and upload it to the block The chain equipment is convenient for each participant equipment and client to query. After the execution body detects the detection requirement submitted by the client, it displays the directory structure, as shown in Figure 3a, for each leaf node in the directory, a user requirement detection package corresponding to a certain industry subdivision corresponds. The user can choose which directory to put the inspection requirements into. In this way, the detection scheme can be accurately determined. Specifically for each detection package, the blockchain will maintain a set of nodes that belong to the user detection package as the root node, and establish the corresponding node set according to the user request detection package selected by the user. The user-customized detection package id is used as an index, and various types of data output during the detection preparation process in response to the detection requirements are distinguished by type, and data rights confirmation and privacy protection are realized through the whitelist mechanism. This facilitates data query and management. The abstraction of node data structure is shown in Figure 3b.

id: unique index, the same user detects the same package id

type: Enumeration of data types, including inspection package/test report/preparation report/expert report/delivery report, etc.

parentNode: The parent node. The user detection package is the root node and has no corresponding parent node

childNodeList: child node (for example, the user detection package contains detection reports of multiple detection departments, each detection report)

whitelist: Whitelist. Digital identities in the whitelist have permission to view the original data

owner: The device that owns the data. You can upload or modify the data fingerprint of this node

ownerUrl: The entry address of the data owner's device, such as the front switch entry of the data owner's device. At least include the data applicant device applying for the original data use authorization to the owner device (corresponding to the process step 4 of the application scenario shown in FIG. 5 ); the data applicant device acquiring the original data (corresponding to the process step 5 of the application scenario shown in FIG. 5 ) ) two interfaces

hash: data fingerprint. Obtained from the original data through the specified hash calculation and uploaded by the owner.

The client queries the predetermined directory on the blockchain, and submits the personal testing requirements to the corresponding directory entry. The delivery device can monitor the events of the detection requirements submitted by the user through the smart contract, and then determine the detection plan according to the detection requirements. The inspection plan may include which equipment of the participating parties, and the specific details of the inspection plan are for example: the processing party's device A processes the material M, the processing party's device B processes the material N, the testing party's device C detects the M, the testing party's device D detects the N, and the expert X Write a test report. There can be more than one processing equipment, more than one testing equipment, and more than one expert.

Step 202: After encrypting the relevant information of the detection requirement and the detection scheme to generate a first fingerprint, store the first fingerprint in the blockchain.

In this embodiment, according to the user's detection requirements, the deliverer's equipment matches the appropriate detector's equipment, the preparer's equipment, and expert resources. The data fingerprints of user detection requirements, data related to requirements, standard information, etc. are stored on the chain. It can be encrypted into a fingerprint by hash, and then uploaded to the blockchain, and the original content is still stored in the database of the deliverer's device. Fingerprints are used for archiving and retrieval. This article deals with generating fingerprints multiple times, so they are distinguished by the numbers "first", "second", etc.

Step 203: Add the digital identities of the participant devices involved in the detection scheme to the first whitelist list of the deliverer device.

In this embodiment, the digital identities of the aforementioned participant devices are added to a whitelist where the corresponding raw data information can be viewed. Only participating devices in the whitelist are eligible to view information about testing requirements and testing solutions. This scheme sets permissions for different information, so it is necessary to set up multiple whitelists, which are distinguished by numbers such as "first" and "second". In the first whitelist are the participants who can view the intermediate data. In the second whitelist are the participants who can see the final test report. The two lists can be the same or different. For the sake of confidentiality, the fewer participants who can see the final test report, the better.

Step 204 , perform data interaction with the participant equipment through the first whitelist, complete the detection items required for detection, and generate a detection report.

In this embodiment, the deliverer device needs to notify the participant devices involved in the first whitelist to perform detection. The textual materials required for the detection can be obtained through the blockchain, but the physical materials used need to be distributed separately. The participating device can perform steps 401-405 to generate a detection report.

In some optional implementations of this embodiment, the method further includes: in response to receiving a request for viewing the original data from the data applicant device, the deliverer device queries whether the digital identity of the data applicant device is in the first white In the list list, the data applicant device includes at least one of the following: a client and at least one participant device. If it is in the first whitelist, send the original data to the data requester device. If it is not in the first whitelist, the device of the data applicant is determined to be an illegal device of the data applicant, and the original data is refused to be sent to the device of the data applicant. Any one of the client and at least one participant device can be used as a data applicant device to request to find data, but authentication is required, and only the data applicant device in the whitelist has permission to view it. The original data is stored in the database of the deliverer's device, and is directly sent by the deliverer's device to the data requester's device. It can be directly sent to the gateway node of the data requester's device through the url address of the data requester's device.

In some optional implementations of this embodiment, the method further includes: sending a data use request message to a data owner device in the participant devices involved in the detection scheme, wherein the data owner device includes at least one participant device . Receive data sent by the data owner device. The deliverer device can also act as a data requester device, requesting usage data from other participant devices that own the data. In the same way, the data owner device will also verify whether the digital identity of the deliverer device is in the whitelist. Only when the identity verification is passed will the requested data be sent directly to the deliverer device. It can be addressed through the url of the deliverer device and sent directly to the gateway node of the deliverer device.

In some optional implementations of this embodiment, the method further includes: in response to receiving the detection report complete message, sending a detection report use request message to the device that owns the detection report, where the device that owns the detection report includes At least one participant device. Receive the detection report sent by the owner device of the detection report, encrypt the detection report to generate a second fingerprint, and store the second fingerprint in the blockchain; add the digital identity of the participant device involved in the detection report to the delivery device on the second whitelist. Each participating device will get the corresponding intermediate data (for example, processing data, detection data, etc.) at the stage that it is responsible for. After the processing or detection is completed, the intermediate data will be encrypted to generate fingerprints and uploaded to the blockchain, and set up to view Whitelist of intermediate data, experts are in the whitelist. Experts write test reports based on intermediate data. After the expert encrypts the detection report and generates the fingerprint and uploads it to the blockchain, the smart contract can automatically monitor the event, and then the delivery device sends a detection report usage request message to the owner device (the expert's client) of the detection report, and passes the identity Get a test report after verification. It is possible to add a whitelist to the digital identity of the client that is delegated to detect. The digital identities of other party devices can also be whitelisted. Only the digital identities in the whitelist of the detection report have the right to view the detection report.

In some optional implementations of this embodiment, the method further includes: in response to receiving a request for viewing the detection report from the data applicant device, querying whether the digital identity of the data applicant device in the detection report is in the second white In the list list, the data applicant device of the detection report includes at least one of the following: a user terminal and at least one participant device. If it is in the second white list, the detection report is sent to the data requesting device of the detection report. Both the client and at least one participant device may apply to find the detection report, but only those in the whitelist have permission to view it.

Continuing to refer to FIG. 4 , there is shown a flow 400 of an embodiment in which the method for managing detection information according to the present disclosure is applied to a participant device. The method for managing detection information includes the following steps:

Step 401, in response to receiving the detection request sent by the deliverer device, determine the resource information involved in the detection request and the owner device of the resource information.

In this embodiment, an electronic device on which the method for managing detection information runs (eg, a participant device (eg, a processing device, a detection device) in the data provider device shown in FIG. 1 ) can receive the delivery party The detection request sent by the device corresponds to the detection scheme in step 201 . The participant device determines the required resource information and the owner device of the resource information according to the detection scheme. Wherein, the owner device of the resource information includes at least one participant device.

Step 402: Send a request for viewing resource information including the digital identity of the participant device to the owner device of the resource information.

In this embodiment, a request for viewing the resource information of the digital identity of the participant device (data applicant device) is sent to the corresponding owner device for resource information. If the resource information belongs to different owner devices, multiple viewing requests need to be sent. The owner device maintains its own whitelist, and only the applicant device whose digital identity is in its whitelist has permission to view it. The owner device returns resource information after successfully authenticating its identity.

Step 403: Receive the resource information fed back by the owner device of the resource information.

In this embodiment, the applicant device receives the resource information fed back by the owner device of the resource information. The data of devices of different owners can be collected and organized, and all the resources required in the detection process can be prepared.

Step 404: Execute the detection process according to the resource information, encrypt the intermediate data of the detection process to generate a third fingerprint, and store the third fingerprint in the blockchain.

In this embodiment, the participant device performs the detection process, and during the detection process, intermediate data will appear in stages. These data are necessary for the detection report, and therefore need to be saved. The original intermediate data can be stored in the local database, the intermediate data is encrypted to generate a third fingerprint, and the third fingerprint is stored in the blockchain.

Step 405, adding the digital identity of the participant device involved in the intermediate data to the third whitelist of the participant device.

In this embodiment, the intermediate data can be shared among some participant devices, so the digital identities of the participant devices participating in the sharing are added to the third whitelist list of the participant devices. In this way, the device of the applicant who is not on the whitelist can be prevented from being accessed, thereby achieving confidentiality.

In some optional implementations of this embodiment, the method further includes: in response to receiving a viewing request for the intermediate data from the data applicant device, querying whether the digital identity of the data applicant device is in a third whitelist , wherein the data requester device includes at least one of the following: at least one participant device and a deliverer device. If it is in the third whitelist, the intermediate data is sent to the data applicant device. The execution subject of this step is the data owner device. The original data of the intermediate data is not uploaded to the chain, only the fingerprint is uploaded to the blockchain, and a whitelist is set. Other participating devices can find the owner device of the intermediate data by retrieving in the blockchain, and then send a viewing request to the owner device of the intermediate data. After the owner device authenticates, it sends the intermediate data to the data applicant device.

In some optional implementations of this embodiment, the method further includes: collecting intermediate data to generate a detection report. The detection report is encrypted to generate a fourth fingerprint, and the fourth fingerprint is stored in the blockchain. The digital identity of the participant device involved in the detection report is added to the fourth whitelist list of the participant device. The execution subject of this step can be an expert client. The expert's client needs to send a viewing request to the device that owns the intermediate data. The device that owns the intermediate data verifies the identity of the expert and sends the intermediate data to the expert's client, thereby collecting all the intermediate data. The expert's client generates an inspection report based on the intermediate data. The original test report is stored locally, the test report is encrypted to generate a fourth fingerprint, and the fourth fingerprint is stored in the blockchain. The digital identity of the participant device involved in the detection report is added to the fourth whitelist list of the participant device. The deliverer device is in this whitelist.

In some optional implementations of this embodiment, the method further includes: in response to receiving a viewing request of the detection report from the deliverer device, querying whether the digital identity of the deliverer device is in the fourth whitelist. If it is in the fourth whitelist, a detection report is sent to the delivery device. After the delivery device monitors the completion of the test report through the smart contract, it requests to obtain the test report, and the expert client authenticates the test report and sends the test report to the delivery device. The test report is a technical analysis, and the delivery device can add some business information on the basis of the test report, for example, the certification certificate of the participant's device, etc., to form a new test report for the user to view. The delivery device needs to encrypt the new test report to generate a fingerprint and upload it to the blockchain.

Continue to refer to FIG. 5 , which is a schematic diagram of an application scenario of the system for managing detection information according to this embodiment. A system for managing inspection information, including: a user terminal, which is used to submit inspection requirements to a predetermined directory of the blockchain, send inspection reports for inspection reports to the deliverer’s equipment, and receive the inspection reports returned by the deliverer’s equipment; the deliverer’s equipment, Used to execute the method of steps 201-204. At least one participant device for performing steps 401-405.

The client, the delivery device and each participant device have their own digital identities on the blockchain. The process of managing the detection information is as follows:

1. The deliverer's equipment catalogs the material testing and preparation services it can provide, and uploads it to the blockchain to facilitate the equipment query of each participant.

2. The target user queries the on-chain directory and submits personal testing requirements to the corresponding directory entry

3. According to the user's testing requirements, the deliverer's equipment matches the appropriate testing equipment, preparation equipment, expert resources, etc. The data fingerprints of the user's detection needs, data related to the needs, standard information, etc. are uploaded to the chain and stored as certificates; at the same time, the digital identities of the aforementioned participant devices are added to the whitelist where the corresponding original data information can be viewed.

4. The participant's device (processing/testing device) submits the original data usage request to the data holder's device (deliver's device or other participant's device).
