The shared client can be downloaded and installed in advance by a data visitor, information interaction is established among the database, the enterprise server, the block chain server, the shared client and the block chain nodes, and the implementation mode for establishing the information interaction refers to the prior art.
The enterprise database may store, in advance, industrial data owned by an enterprise (for example, data related to goods owned by the enterprise) and an index code of the industrial data, where the index code of any industrial data uniquely indicates the industrial data. It should be noted that the disclosure level of the industrial data stored in the local database includes public data (disclosure level is 3 level), authorized public data (disclosure level is 2 level), and secret data (disclosure level is 1 level). The public data is industrial data which can be accessed by any data visitor, the authorized public data is industrial data which is only limited to the authorized data visitor, and the secret data is industrial data which cannot be accessed. It should be noted that the access operation includes a query operation, a sharing operation, and/or a parsing operation.
Before the information processing system for realizing data sharing realizes data sharing, an enterprise can convert industrial data in the database into decentralized data, and a foundation is laid for subsequent data sharing.
The conversion process of the industrial data is shown in fig. 2, and comprises the following steps:
s201, the enterprise server sends a data decentralized request to the blockchain server, wherein the data decentralized request comprises information of enterprises.
And S202, the node (hereinafter referred to as a blockchain node) on the blockchain triggered by the blockchain server performs consensus verification on the enterprise information, and after the consensus verification is passed, the data conversion response is sent to the enterprise server.
And if the consensus verification fails, sending prompt information of failing to pass the verification to the enterprise server.
And S203, after receiving the data conversion response, the enterprise server sends the index code, the storage address and the public level information of the industrial data in the database to the block chain server.
The storage address refers to an address of a storage space of the industrial data.
S204, the block chain server generates a decentralized identity code of the industrial data and a corresponding data decentralized document.
It should be noted that, the blockchain server re-encodes the index code according to a preset encoding rule to obtain the decentralized identity code of the industrial data. The encoding rules can be referred to in the prior art and are not described in detail here.
Specifically, the centralized identity code of any industrial data includes: the method comprises the steps of presetting an identification, an analysis method and a unique identification. The coding format of the decentralized identity code of the industrial data is as follows: "preset identification field: and analyzing a method field: the unique identification field' is used, wherein the value of the preset identification field indicates the coding form of the decentralized identity code of the industrial data, the value of the analysis method field indicates the analysis mode of the decentralized identity code of the industrial data, and the value of the unique identification field uniquely indicates one piece of industrial data.
Optionally, in order to improve readability of the decentralized identity of the industrial data, the decentralized identity of the industrial data further comprises a type indicator for indicating a disclosure level of the industrial data, as described above, the disclosure level indicating disclosure, authorization disclosure or secret, for example, the type indicator "s" indicates that the disclosure level of the industrial data is secret data.
In summary, an example of the decentralized identity code of the industrial data is: "decentralized identity: the decentralized identity code analysis method comprises the following steps: 123456djfuim-s ", wherein the value of the preset identification field is" decentralized identity ", which indicates that the encoding form is distributed identification, the value of the analysis method field is" decentralized identity analysis method ", which indicates that the analysis mode of the decentralized identity is decentralized identity analysis method. The value of the unique identification field is '23456 djfuim', which represents the unique code of the industrial data, wherein,'s' is a type indicator of the identity code of the industrial data, indicating that the industrial data to be shared is secret data.
Decentralized documentation of industrial data includes: the public key, access address, and operational information of the owner of the industrial data.
The access address is a storage address of specific content of the industrial data, specifically, the storage address of the public data may be a public URL, the storage address of the authorization data is an address requiring an authorization key, and the storage address of the secret data is null.
The operation information includes: the query information is a record for querying the industrial data corresponding to the document, specifically, a query decentralized identity code, and the shared information is a record for sharing the industrial data corresponding to the document, specifically, a shared decentralized identity code. In the initial (i.e., no query and sharing operations have been performed) case, the query information and the shared information are empty.
Optionally, the document includes two regions, a security level of the first region is higher than that of the second region, the first region is used for storing the query information and the shared information, and the first region may be only open to an owner of the industrial data, that is, an enterprise authority, so that the enterprise can query the query and shared records of the industrial data. The second area is used for storing the storage address of the industrial data.
S205, the block chain server sends the decentralized identity code of the industrial data to the enterprise server, and the enterprise server can correspondingly store the decentralized identity code and the industrial data to the database.
S206, the block chain server stores the data decentralized document of the industrial data.
Specifically, the data decentralized document may be stored in a block chain node, or, in order to save the space of the block chain node, the data decentralized document may also be stored in a content addressable network, such as ipfs, and queried in an anchoring manner, and the storage address of the encoded document of the query operation is sent to the block chain for storage.
The process shown in fig. 2 achieves the purpose of configuring decentralized identity codes and documents for the industrial data of an enterprise through the interaction of an enterprise server, a blockchain server and blockchain link points, and lays a foundation for subsequent industrial data sharing.
FIG. 3 is a process of a user of a shared client querying industrial data through the shared client, including the following steps:
s301, the sharing client responds to the query keyword of the data request party and sends a query request to the enterprise server.
Wherein, the user of the client can input the query keyword at the sharing client, for example: the query request includes the keywords "enterprise a", "cost of nut", and "production cycle", and the query keyword represents a request to initiate a query to the shared client for "cost of nut produced by enterprise a" and "production cycle of nut produced by enterprise a".
In this embodiment, the sharing client sends a query request including the keyword to a query interface in the enterprise server.
S302, the enterprise server receives the query request, and obtains the decentralized identity code of the industrial data to be shared according to the keyword query in the database.
Specifically, the industrial data is inquired in the database by using the keywords, and then the decentralized identity code corresponding to the industrial data is obtained.
S303, the enterprise server sends the query result to the sharing client.
In this embodiment, the query result includes a decentralized identity of the industrial data to be shared.
S304, the sharing client receives the query result.
S305, the sharing client displays the query result.
In this embodiment, the step of obtaining the decentralized identity code of the industrial data to be shared as the query result includes: a preset identifier, a parsing method, a unique identifier, and a type indicator.
In this embodiment, the identity code of any industrial data uniquely indicates a piece of pre-stored industrial data, for example, the industrial data to be queried includes: data 1 stored in the local database of enterprise a: cost of nut, and data 2: and in the production period of the nut, the shared client displays the decentralized identity code corresponding to the data 1 and the decentralized identity code corresponding to the data 2.
It should be noted that, in the case of a failure of the query (for example, the enterprise server does not retrieve the decentralized identity code of the industrial data according to the keyword), the shared client displays a prompt message indicating that the retrieval is not the result.
S306, the sharing client generates a decentralized identity code of the query operation and a corresponding query decentralized document.
In this embodiment, the decentralized identity code of the query operation uniquely identifies the query operation, and the encoding format of the decentralized identity code of the query operation may refer to the encoding format of the identity code of the industrial data.
Specifically, querying a decentralized document includes: information of the data inquirer, keywords, and the inquiry result (i.e. the data decentralized identity code of the industrial data as the inquiry result). And under the condition that the industrial data is not inquired according to the keywords, the inquiry result is null. Optionally, the query recentered document further includes a query time indicating a time at which execution of the query operation is complete.
In this embodiment, the query recentered document may be stored in the block chain, or may be stored in a content addressable network, for example, ipfs, and the query recentered document storage address is sent to the block chain for storage by an anchor query.
Optionally, in the case that no industrial data is queried, a special identifier may be set in the decentralized identity code of the query operation to indicate that the query operation of the identity code identifier does not query industrial data, and/or the query decentralized document corresponding to the decentralized identity code of the query operation is stored in a special storage area, and also indicate that the query operation of the identity code identifier does not query industrial data. The special storage space may be a storage space on a blockchain server.
Optionally, the special identifier may be set to be identifiable by only the operator of the blockchain, or the special storage space is accessible by only the operator of the blockchain, which is beneficial for the operator of the blockchain to know the deviation between the query intention and the actual industrial data.
S307, the sharing client sends the decentralized identity code of the query operation to the block chain storage.
S308, adding the decentralized identity code of the query operation in the data decentralized document of the queried industrial data by the sharing client.
Specifically, as described above, the decentralized identity code of the query operation is written into the first region of the data decentralized document of the queried industrial data.
As can be seen from the process shown in fig. 3, the sharing client provides the function of querying the industrial data, and can display the decentralized identity code of the industrial data to be queried. Furthermore, the query operation is recorded, so that subsequent tracing is facilitated.
After acquiring the decentralized identity code of the industrial data to be queried, the data visitor can confirm the disclosure level of the industrial data to be queried according to the type indicator, if the industrial data is authorized to be disclosed, authorization needs to be acquired, and fig. 4 shows a process in which the data visitor interacts with a block chain through a sharing client to realize data sharing, which includes the following steps:
s401, the sharing client sends the data sharing request to the block chain node.
In this embodiment, the data requester may input a decentralized identity code of the industrial data to be shared at the sharing client to trigger generation of a data sharing request, where the data sharing request includes: decentralized identity of industrial data to be shared and information of data requesting party. It should be noted that the decentralized identity of the industrial data to be shared is obtained by triggering a query operation at the sharing client by the data requestor.
Specifically, the sharing client may convert the data sharing request into a triggering parameter, where the triggering parameter includes an identity code of the industrial data to be shared and information of a data requester. The triggering parameter is used for triggering the block chain to carry out consensus verification on the data request party according to the intelligent contract.
S402, carrying out consensus verification on the data request party according to a preset intelligent contract by the block link points.
In this embodiment, the method for performing consensus verification on the intelligent contract parameters based on the consensus mechanism of the block chain may refer to the prior art.
And S403, if the verification is passed and the data requester passes the authorization, feeding back a sharing request feedback result of the indication key by the block link point.
The key is used for decrypting a data decentralized document of industrial data to be shared, and in the embodiment, the key comprises: the private key of the owner of the industrial data to be shared.
S404, if the verification fails, the data request party does not pass the authorization, the block link point feeds back a sharing request feedback result indicating that the consensus verification fails, and the data request party cannot decrypt the data decentralized document of the industrial data to be shared.
S405, the sharing client receives and displays the sharing request feedback result.
S406, the sharing client generates a decentralized identity code of the sharing operation and a corresponding sharing decentralized document.
In this embodiment, the decentralized identity code of the sharing operation uniquely identifies the sharing operation, and the coding format of the decentralized identity code of the sharing operation may refer to the coding format of the data decentralized identity code of the industrial data.
Specifically, sharing a decentralized document includes: the method comprises the steps of decentralizing identity codes of industrial data to be shared, information of owners of the industrial data to be shared, information of data requesters, identification of intelligent contracts and sharing request feedback results. Optionally, the shared decentralized document further comprises a sharing time indicating a time at which the execution of the sharing operation is completed.
