Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 shows a flow chart of an end-to-end based data service method according to an embodiment of the present disclosure. The method can be applied to a data service platform, which can be a data service platform based on a blockchain, for example, a data service platform based on a federation chain in a blockchain, and the data service platform can be constructed as an end-to-end (end-to-end) peer-to-peer network through cryptography and a distributed manner of the blockchain.
The data service platform may include data for registered account transaction, that is, different registered accounts may perform data transaction in the data service platform. A user registering an account may see data for a transaction in the data services platform and may request data that is desired to be transacted. The registered account may be an account registered in the data service platform, and the registered account may be a federation member of the data service platform.
It should be noted that the data used for transaction in the data service platform are profile information of data, for example, data description information, the data service platform does not include complete data, and includes only data description information, and a user who registers an account can only see the data description information, that is, the data service platform does not store data, only stores the data description information, and the data service platform does not transmit data, only transmits transaction information of the registered account, or only transmits information in the process of performing data service for the registered account. Moreover, because the data service platform is based on the blockchain technology, the data service platform can perform accounting on the transaction information, and the accounting mode can be realized according to a consensus mechanism, for example, accounting on data requests, data request responses, data transaction fees, and other behaviors, or setting an accounting frequency for accounting, which is not limited in the disclosure. As long as the accounting mode can ensure the safety of the transaction, ensure the infringement tracking of the transaction and the like.
The data service process of the data service platform is described below by taking an example that a first node requests data which is desired to be traded from a second node, wherein the first node and the second node are terminal devices, such as computers and the like, used by a registered account of the data service platform, and the first node and the second node correspond to different registered accounts, that is, the registered account logged in by the first node is different from the registered account logged in by the second node.
As shown in fig. 1, the method may include:
step S11, generating data request information according to the data request of the first node;
step S12, sending data request information to the second node according to the data request information;
step S13, receiving response information of the data request information and data address information sent by the second node;
step S14, if the response information of the data request information is the request data, generating a key according to the data transaction mode;
step S15, sending the key and the data address information to the first node to make the first node obtain the data.
The user of the registered account in the data service platform may see data (profile information/data summary information) for transaction in the data service platform, if there is a user who wants to request the data, for example, the user of the first node wants to request the data of the user of the second node, the user of the first node may click the data to make a request, and the data service platform may generate data request information according to the data request of the first node, where the data request information may include an identifier of the second node, an identifier of the requested data, and the like.
It should be noted that the data for transaction in the data service platform all have matching intelligent contracts, for example, description information of the transaction data, and the first node has seen and agreed the intelligent contracts by default when clicking the data to make a request.
The data service platform can acquire that the first node requests the data of the second node according to the data request information, and the data service platform can send the data request information to the second node. The second node may check whether the request is allowed according to the data request information, for example, check whether a registered account of the first node has a right to request the data, whether the data used by the first node conforms to an intelligent contract matched with the data, and the like, and if the check is that the request is not allowed, the second node may send information of rejecting the request to the data service platform so that the data service platform informs the first node; if the request is allowed, the second node may send the information of allowing the request and the data address information to the data service platform.
And if the data service platform receives that the response information of the second node to the data request information is refused, directly forwarding the information of the refused request to the first node.
If the data service platform receives that the response information of the second node to the data request information is allowed, the data service platform can generate a secret key according to a data transaction mode.
The data service platform may send the key and data address information to the first node to cause the first node to obtain the data.
Optionally, if the secret key includes a private key, the data service platform may also ask the second node whether to send the private key to the first node, and after the second node confirms that the private key can be sent to the first node, the private key is sent to the first node.
Optionally, the data service platform may also receive the verified (approved) fee of the first node and the second node for charging.
The settlement of the data service can be carried out by the first node and the second node together, after the data delivery is completed, the first node and the second node can verify the cost, and if both the first node and the second node approve the cost, the cost can be reported to the data service platform, so that the data service platform can complete the charging process of the data service.
The data service platform based on the block chain is used for carrying out data service on the registered account, and the data of the registered account is forwarded through the data service platform in a data address information mode; and the data service platform can be prevented from participating in the data delivery process, so that the data service platform is prevented from reserving data, the privacy of the data is ensured, and the data of the registered account is prevented from being leaked through the data service platform.
In one possible implementation, the data request information may include data description information, intelligent contracts, and additional information; the data description information comprises data identification, data abstract and identification of a node to which the data belongs.
The registered account can know the summary information of the data and the node to which the data belongs through the data description information. The data identification is used to distinguish data for transactions in the data services platform. The additional information may be data-related information input by the registered account (data asset purchaser) of the first node, for example, information related to data usage, data charges, etc., such as data charges deemed reasonable by the first node, request information for other data related to the data, time when data usage is desired, etc., i.e., the additional information may be information that the first node wishes to negotiate with the registered account (data seller/data asset provider) of the second node.
In one possible implementation, the smart contracts may include one or more of the following: the name of the intelligent contract, the transaction content, the transaction state, the data use time limit, the data use area limit, the fee information, the payment mode, the transaction frequency limit value and the data transaction mode. The data usage time limit and the data usage area are limited to data usage rights, and the transaction time limit refers to the maximum number of times that the data can be transacted, for example, 1000 times, 10000 times, and the like.
Before purchasing data, a data asset purchaser needs to carefully read the contents in the intelligent contract to determine whether the authority information accords with the data asset purchaser, so that the effectiveness of a data request is improved.
In a possible implementation manner, the data address information may be determined by the second node according to the data transaction manner.
In one possible implementation, the data address information may include offline data address request information or a link address; the data transaction mode can comprise an API transaction mode, an off-line transaction mode or a data security platform transaction mode;
the link address can be determined by the second node according to the API transaction mode or the data security platform transaction mode; the offline data address request message may be determined by the second node according to the offline transaction manner.
Fig. 2 shows a flowchart of step S14 according to an embodiment of the present disclosure. As shown in fig. 2, in a possible implementation manner, the step S14 may include:
step S141, if the data transaction mode is an API transaction mode or a data security platform transaction mode, generating a public key and a private key;
step S142, if the data transaction mode is an off-line transaction mode, generating a private key;
the public key is login information, and the private key is the use permission of data. Namely, the public key is used by the first node when the webpage corresponding to the link address is logged in, and the private key can be used by the first node to call or use the data. The public key may include an account, a digital certificate, etc., and may be implemented using public key infrastructure (pki). The private key may comprise a hash value or the like.
If the data service platform receives the response information of the second node aiming at the data request information as permission, a data transaction mode can be obtained from the intelligent contract and is judged, and if the data transaction mode is an API (application programming interface) transaction mode or a data security platform transaction mode, a public key and a private key can be generated for the data transaction (the data transaction between the first node and the second node); if the data transaction mode is an off-line transaction mode, only the private key can be generated for the data transaction.
Optionally, if the first node receives the public key, the private key and the link address, the data asset purchaser of the first node may click the link address and jump to a login page of the API data platform or a login page of the data security platform, in an example, if the data transaction mode is the API transaction mode, the link address is the login page of the API data platform; and if the data transaction mode is a data security platform transaction mode, the link address is a login page of the data security platform. Wherein the API data platform and the data security platform may be websites associated with the first node.
The first node can log in a login page of the API data platform or a login page of the data security platform by using a public key, and after logging in, the API data platform or the data security platform already has data requested by the first node. I.e., the user of the first node (the data asset purchaser) can only see the requested data. The data in the API data platform or the data security platform may be directly sent to the API data platform or the data security platform by the second node after determining that the data request of the first node is allowed.
The first node may call the data in the API data platform or the data security platform using the private key. For example, in the API data platform, the first node may perform data query through a query function, at this time, the API data platform needs to call the data to perform query, and if the private key of the first node is verified, the API data platform returns a query result in XML, JSON (JSON object Notation), or other defined format, that is, the first node successfully calls the data of the API data platform by using the private key.
Optionally, a plurality of tools may be configured in the data security platform for the first node to operate to implement a plurality of functions, for example, a data graph function, a data analysis function, and the like. The first node only needs to click corresponding functions, the private key can pass verification, the data security platform can directly call the data to automatically analyze the data or produce a chart, and the first node can also derive the data processing results. The data security platform has multiple functions, so that the operation is simple, and the data can be conveniently used by scientific research personnel.
Fig. 3 illustrates a flow chart of an end-to-end based data service method according to an embodiment of the present disclosure. As shown in fig. 3, in one possible implementation, the method may further include:
step S16, receiving data description information uploaded by a registered account in the data service platform, sample data and intelligent contract options matched with the data description information;
and step S17, if the data description information and the sample data are qualified, setting the data description information, the sample data and the intelligent contract option matched with the data description information to be shared in the registered account.
The data for transaction in the data service platform are uploaded by a registered account (a data asset purchaser and/or a data asset supplier) and pass verification through the data service platform, and the data for transaction in the data service platform are data description information and are not complete data, so that the data of the registered account is prevented from being reserved by the data service platform.
The data service platform receives the data description information uploaded by the registered account and the intelligent contract option matched with the data description information, and can check whether the data description information is qualified, for example, whether the registered account to which the data in the data description information belongs is true (identity identification and verification), whether credit is qualified, and the like can be checked or verified, whether the data corresponding to the data identifier exists, whether the data can be called, and the like can be verified, if the data description information is qualified, the data description information can be determined to be qualified, the data description information and the intelligent contract option matched with the data description information can be set to be shared in the registered account, and the data description information and the intelligent contract option matched with the data description information can be seen by the registered account in the data service platform.
The steps S16 and S17 may be performed before step S11.
Optionally, when the first node wants to request data, the first node may click on the selected data description information and pick up the selected data description information from the intelligent contract options matched with the data description information, for example, a required or preferred data transaction mode may be picked up, and after the selection is determined, the data service platform generates an intelligent contract; if the user of the first node further inputs the additional information, after the input of the additional information is completed, the data service platform may generate the data request information of the first node according to the request data description information, the intelligent contract, and the additional information of the first node, and then proceed to step S12.
It should be noted that the registered account may also be an intelligent contract matched with the data description information, that is, the first node cannot participate in checking to determine the intelligent contract, and when the first node clicks the selected data description information, the first node agrees by default to the intelligent contract matched with the data description information.
The data service platform guarantees the credit degree of the data and the safety of the transaction through the examination and verification of the uploaded data.
In one possible implementation, the data service platform has a matching mechanism for providing value added services; the value added services may include data mining for registered accounts and/or screening registered accounts for data for transactions.
The data service platform may mine valid data for the registered account and may filter data for the registered account for transactions, e.g., filter data that meets market requirements. Through the provision of the value-added service, the data description information uploaded to the data service platform by the registered account is easier to realize transaction, and the use population of the data service platform can be expanded.
In one possible implementation, the data service platform may have a billing function, and the billing function may include: billing of data and billing of data transactions. That is, the billing of the data service platform is divided into two chains: a data chain and a transaction chain. The data chain is used for carrying out accounting on data in the data service platform, for example, accounting on data description information and sample data.
The accounting of the data transaction may include accounting for the operation of the data, accounting for a registered account for the operation of the data. Wherein the data comprises data description information, sample data or data corresponding to the data description information; the manipulation of the data includes one or more of: uploading data, auditing data, requesting and responding data, using data and charging data transaction. For example, the accounting of the data transaction may be uploading of data description information and sample data, a registered account of the uploading, use of data corresponding to the data description information, a registered account using data corresponding to the data description information, and the like.
The data service platform can comprise a verification node and a non-verification node, and the verification node can perform accounting, account book maintenance, transaction operation and the like; non-authentication nodes can only maintain security context between nodes, request services from authentication nodes on behalf of users, etc.
Fig. 4 illustrates a schematic diagram of data transaction and billing in an end-to-end based data service method according to an embodiment of the present disclosure. As an example, as shown in fig. 4, the block chain billing of the data service platform can be divided into two chains of data billing and data transaction billing, and the billing is performed through the underlying blocks. The data asset provider and the data asset purchaser correspond to different registered accounts in the data services platform.
As shown in fig. 4, the data asset purchaser may browse a data asset list (data description information, sample data, and an intelligent contract option matching with the data description information) in a system home page of the data service platform, and the data asset purchaser may also use the sample data, if there is data to be purchased, may click a corresponding data placement, that is, make a data request, the data service platform may pop up an order payment page, the data asset purchaser may pay, and after the order payment, if the data request is allowed by the data asset provider, the data service platform may return my order of the data asset purchaser, and the my order may include purchased data, an intelligent contract, a data asset provider, and the like; the data asset provider may return data address information to the data asset buyer according to a data transaction mode in the smart contract, for example, the data transaction mode may be an offline transaction mode, the data asset buyer may return a page, the page may include an address input box and "request to input a mailing address of your offline data", after the data asset buyer inputs, the data service platform forwards the mailing address to the data asset provider, the data asset provider may post data to the mailing address, for example, the data may be encrypted and stored in a usb flash disk, the usb flash disk is encrypted, and the encrypted usb flash disk is mailed to the mailing address so that the data asset buyer obtains the requested data.
The data involved in the above process is billed per se, i.e. the data content is recorded; the overall process of trading of data involved in the above process is billed, as are the data asset buyers and data asset suppliers involved in the trading process.
It should be noted that the data asset provider and the data asset purchaser are only for this transaction, and the data asset provider may also be used as the data asset purchaser and the data asset purchaser may also be used as the data asset provider.
