Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a method for monitoring quality of blockchain data according to an embodiment of the present invention, where the method is applicable to a data quality monitoring situation, and the method can be executed by a device for monitoring quality of blockchain data according to an embodiment of the present invention, where the device can be implemented by software and/or hardware, and can be integrated in an electronic device such as an intelligent terminal for monitoring data quality.
As shown in fig. 1, the method for monitoring quality of block chain data includes:
s110, receiving shared data of a data provider, and acquiring identity information of the data provider.
The shared data may be a code, a document, or a picture. The data provider may provide any form of shared data.
In this embodiment, the identity information may be the name, address, number, etc. of the data provider, and the identity information of the data provider is obtained to trace the data provider. For example, the identity information of the data provider is a name, and the data provider identity can be determined. Preferably, the identity information may be a number, and different users may use the respective numbers on the blockchain, and the corresponding data provider may be found through the numbers.
In this embodiment, the blockchain server is used to receive the shared data provided by the data provider. The data sharing on the blockchain means that a blockchain participant (data provider) stores data into an intelligent account book of the blockchain by calling an intelligent contract of the blockchain, and other blockchain participants (data users) can inquire the shared data by calling the intelligent contract of the blockchain. A block chain (block chain) is a decentralized database. The distributed node consensus algorithm is a brand new distributed infrastructure and computing mode which uses a block chain data structure to store data, uses a distributed node consensus algorithm to verify and update data, uses cryptography to ensure the safety of data transmission and access, and uses automated script codes to operate data.
S120, encrypting the identity information to obtain an encryption result; and transmitting the shared data and the encryption result association to a block chain.
Among other things, encryption is a technique for restricting access to data transmitted over a network. The encoded data resulting from the original data being encrypted by the encryption device and the key is referred to as ciphertext. The process of restoring the ciphertext to the original plaintext is called decryption, which is the reverse process of encryption, but the decryptor must decrypt the ciphertext with the same type of encryption device and key.
In this embodiment, the encryption processing on the identity information may be symmetric encryption or asymmetric encryption. In the symmetric encryption algorithm, a data sender and a data receiver use the same set of rules to encrypt and decrypt data; asymmetric encryption refers to encryption techniques integrated into a blockchain to meet security requirements and ownership verification requirements. It differs from symmetric encryption mainly in that symmetric encryption uses a shared key to decrypt data, whereas asymmetric encryption uses a "key pair" to decrypt data, the key pair comprising two parts: one public key and one private key. Preferably, the identity information is encrypted by adopting an asymmetric encryption mode. The identity information is encrypted in an asymmetric encryption mode, so that the safety of the ciphertext in the transmission process can be ensured.
In the present embodiment, the encryption result may be an unreadable code, document, or picture. Only holding the corresponding decryption key can decrypt the encrypted information into readable plain text.
In this embodiment, the shared data and the encryption result are associated and transmitted to the blockchain, that is, the corresponding encryption result can be determined by the shared data. The data user can obtain the shared data sent by the data provider, and can also obtain the ciphertext of the identity information of the data provider, when finding the data with problems, the data user can initiate tracing, decrypt the ciphertext of the identity information of the data provider to obtain the identity information of the data provider.
In this technical solution, optionally, the encrypting the identity information to obtain an encryption result includes:
processing the identity information by adopting a threshold encryption algorithm to obtain at least two key fragments;
and encrypting the at least two key fragments by adopting the encryption public keys stored by the at least two coalition members associated with the shared data to obtain key fragment ciphertexts.
In this embodiment, the threshold encryption algorithm may be an algorithm that divides the identity information into multiple pieces of information and encrypts the pieces of information respectively during encryption. For example, the identity information may be divided into n shares using a threshold encryption algorithm.
In this embodiment, the encryption public key stored by the federation member associated with the shared data is used to encrypt the key fragment, so as to obtain a key fragment ciphertext. Namely, the encryption public keys stored by different alliance members are adopted for encrypting each key fragment. It can be understood that when there are n key fragments, n coalition members are required to encrypt the key fragments by using the stored encryption public keys to obtain key fragment ciphertexts.
The encryption public keys stored by the at least two coalition members associated with the shared data are used for encrypting the at least two key fragments to obtain the key fragment ciphertexts, so that each key fragment can be encrypted by adopting different encryption methods, and the safety of the key fragment is ensured.
In the present technical solution, optionally, the number of the coalition members is the same as the number of the key fragments;
the encrypting the at least two key fragments by using the encryption public keys stored by the at least two coalition members associated with the shared data includes:
and distributing the at least two key fragments to at least two alliance members to encrypt by adopting alliance member encryption public keys corresponding to the key fragments.
In this embodiment, the number of the coalition members is the same as the number of the key fragments, that is, the identity information may be divided into a plurality of key fragments with the same number as the number of the coalition members according to the number of the coalition members. For example, when the number of the coalition members is 5, the identity information is divided into 5 key fragments; when the number of the coalition members is 2, the identity information is divided into 2 key fragments.
In this embodiment, when the number of the coalition members is the same as the number of the key fragments, the key fragments may be distributed to each coalition member, and each coalition member may encrypt the key fragments by using the encryption public key. For example, if the number of the coalition members is 2, and a and B are used for representing the coalition members respectively, the identity information can be divided into 2 ciphertext fragments, a and B are used for representing the ciphertext fragments respectively, the ciphertext fragment a can be distributed to the member of the coalition a for encryption, and the ciphertext fragment B can be distributed to the member of the coalition B for encryption; and if the ciphertext fragment a is distributed to the member of the B alliance for encryption, the ciphertext fragment B is distributed to the member of the A alliance for encryption.
At least two key fragments are encrypted by adopting the encryption public keys stored by at least two coalition members related to shared data, so that the identity information of a data provider can be effectively kept secret.
In this technical solution, optionally, after encrypting by using the public encryption key of the federation member corresponding to the key fragment, the method further includes:
and associating and transmitting the member number of the coalition member and the key fragment ciphertext to a block chain.
In this embodiment, the member number may be a numeric number or an alphabetical number. According to the block chain requirement setting. For example, federation members may be numbered with 1, 2, and 3, or with A, B, and C.
In this embodiment, the member number of the coalition member is associated with the key fragment ciphertext, that is, the key fragment ciphertext corresponding to the member number of the coalition member can be found through the member number of the coalition member, and the coalition member corresponding to the key fragment ciphertext can also be found through the key fragment ciphertext.
The member number of the coalition member and the key fragment ciphertext are transmitted to the block chain in an associated mode, so that subsequent coalition members can decrypt the key fragment ciphertext conveniently.
S130, responding to a shared data tracing request of a data user, and initiating voting to the alliance members related to the shared data.
In this embodiment, the shared data tracing request may be that when the data user uses the shared data, the data user considers that the data is in a problem, sends the shared data tracing request, and queries the identity information of the data provider. The shared data tracing request may be a tracing request in a form of sending a data quality complaint, or a tracing request in a form of clicking complaint operation.
In this embodiment, a federation member may be a member that supervises data. The coalition members initiate proposals by calling a block chain intelligent contract, any member in the coalition can initiate proposals for a certain event, and the data quality governance relates to a plurality of operation events, but the operation events are initiated by a coalition co-governance mode, namely, no member can independently execute and decide a certain operation. The intelligent contract is also called an intelligent contract and is a program which is event-driven, has a state, obtains multiple-party approval, runs on a block chain and can automatically process assets according to preset conditions, and the intelligent contract has the greatest advantage of utilizing a program algorithm to substitute for human arbitration and execution of the contract.
In this embodiment, when a data consumer finds data problematic, a vote may be initiated to a coalition member associated with the shared data, the coalition member voting proposal by invoking the block chain intelligent contract. The result of the voting by the members of the alliance is 'agreement' or 'rejection', when the 'agreement' or 'rejection' exceeds a certain proportion, the final result of the proposal is 'pass' or 'fail', and the proposal passing the proposal will generate the final execution effect. When the final result is 'pass', the alliance member can acquire the information of the data provider and transmit the information to the block chain; when the final result is 'fail', the federation members can reject the shared data tracing request of the data user. Preferably, the proposed end result is a pass when the league member votes that the agreed proportion is greater than the rejected proportion. For example, when 5 of the voting results of the members in the alliance agree and 4 reject the voting results, the proposed final result is pass; when there are 4 agrees and 5 rejections in the voting results of the coalition members, the proposed final result is fail.
In this embodiment, the shared data and the coalition members are associated with a certain rule, that is, the coalition members corresponding to the shared data can be determined by the shared data. Wherein, certain rules can be numbering, sorting, and the like. For example, the shared data is divided into a data and B data, the federation members can be divided into A members and B members, the a data can be associated with the A members, and the a data can be associated with the B members. The rules may be set according to requirements on the blockchain.
In this technical solution, optionally, responding to the request for tracing to the source of the shared data of the data user includes:
determining whether the shared data tracing request has problem information or evidence information uploaded by a data user;
and if so, sending the problem information or the evidence information to the coalition members associated with the shared data.
In this embodiment, the problem information or the evidence information uploaded by the data user may be used to prove that the data has a problem, and is used for the coalition members to determine whether the shared data has a problem. The question information or the evidence information may be information in a form or information in a document form.
By sending the issue information or evidence information to the coalition members associated with the shared data. The method and the device can be used for the coalition members to judge the shared data uploaded by the data provider, improve the voting accuracy of the coalition members and save the voting time.
In this technical solution, optionally, determining whether the shared data tracing request has problem information or evidence information includes:
and if a problem information or evidence information uploading request of a data user is received, providing a form to the data user so that the data user fills in the problem information or evidence information in the form.
In this embodiment, the form may be in the form of Word or in the form of Excel.
In this embodiment, the request for uploading the problem information or the evidence information of the data user may be sending the request for uploading through a click operation, or may be sending the request for uploading through a sending code.
In this embodiment, when the shared data tracing request has problem information or evidence information and receives a problem information or evidence information uploading request of a data user, a form may be provided to the data user for the data user to fill the problem information or evidence information in the form.
By receiving the problem information or evidence information uploading request of the data user and providing the form to the data user, more standard problem information or evidence information can be obtained, and the working efficiency and accuracy of the voting of the members in the alliance are improved.
And S140, if the voting result meets the preset condition, decrypting the encrypted result by adopting a decryption algorithm to obtain the identity information of the data provider so as to monitor the quality.
In this embodiment, the preset condition may be that a plurality of voting results pass. For example, there may be 5 votes passing through the coalition members; or there may be 3 votes passing in the coalition members. The setting can be made according to the members of the alliance.
In this embodiment, the decryption algorithm corresponds to the encryption algorithm, that is, the encryption algorithm uses public key encryption and the decryption algorithm uses private key decryption, or the encryption algorithm uses private key encryption and the decryption algorithm uses public key decryption. Preferably, the decryption algorithm is decrypted by using a private key, so that the security of the identity information of the data provider in the transmission process can be ensured.
In this embodiment, the identity information of the data provider is obtained for quality monitoring. The quality monitoring can be completed by carrying out failure processing on the problem data, or can be completed by controlling the shared data uploaded by the data provider.
In this technical solution, optionally, the voting result meets a preset condition, which includes:
and the voting agrees to the number of the members in the alliance is larger than or equal to a set threshold value.
In this embodiment, the threshold may be set according to the number of coalition members. For example, the threshold value may be 3 or 5.
In this embodiment, the federation members vote on the shared data tracing request of the data user, some of the federation members vote that the result is agreed, and some of the federation members vote that the result is not agreed, the results of all the tables are counted, the number of the agreed voting results and the number of the disagreeable voting results are determined, and whether the number of the agreed federation members is greater than or equal to the set threshold value or not is judged.
And determining whether the voting result meets the preset condition or not by setting a threshold value, and determining whether to decrypt the encrypted result or not by using the voting result of the members in the alliance, so as to ensure the healthy development of the whole block chain data sharing network.
In this technical solution, optionally, after initiating the voting to the coalition members associated with the shared data, the method further includes:
and if the voting agrees that the number of the alliance members is smaller than the set threshold value, the voting result does not accord with the preset condition, and shared data tracing request rejection information is fed back to the data user.
In this embodiment, the rejection information may be fed back to the data user in the form of an email or in the form of a document. The reject information may be reject tracing or failure of the tracing request.
In this embodiment, when the number of the coalition members agreed by the voting is less than the set threshold, it indicates that most of the coalition members do not agree to decrypt the encrypted result, and then the shared data tracing request rejection information is fed back to the data user.
By feeding back the shared data tracing request rejection information to the data user, the data user can be prompted to check the shared data tracing request, and whether the shared data has problems or not can be determined again.
In this technical solution, optionally, decrypting the encrypted result by using a decryption algorithm to obtain the identity information of the data provider includes:
decrypting each key fragment ciphertext by adopting a private key of a coalition member to obtain key fragments;
and splicing all the decrypted key fragments to obtain the identity information.
In this embodiment, when the voting result meets the preset condition, the private key of the coalition member is used to decrypt each key fragment ciphertext to obtain the key fragment, and the key fragment is transmitted to the block chain. When the private key of the coalition member is adopted to decrypt each key fragment ciphertext, the association between the coalition member and the key fragment ciphertext needs to be determined firstly, and the key fragment ciphertext can only be decrypted by the associated coalition member by adopting the private key. For example, if the federation member a is associated with the key fragment ciphertext a and the federation member B is associated with the key fragment ciphertext B, the federation member a may decrypt the key fragment ciphertext a but may not decrypt the key fragment ciphertext B.
In this embodiment, the coalition members decrypt each key fragment ciphertext respectively to obtain a plurality of key fragments, and splice the key fragments to obtain the identity information. The key fragments can be spliced according to the fragment sequence of the key fragments.
The identity information can be obtained by decrypting each key fragment ciphertext by the coalition members, thereby realizing tracing to the data provider and ensuring the healthy development of the whole block chain data sharing network.
In this technical solution, optionally, before decrypting each key fragment ciphertext by using a private key of a coalition member to obtain a key fragment, the method further includes:
reading member numbers related to each key fragment ciphertext; and the member number is stored in an associated manner after being encrypted by the public encryption key of the coalition member.
The member number associated with each key fragment ciphertext is read, so that the coalition members associated with the key fragment ciphertext can decrypt each key fragment ciphertext, and the working efficiency is improved.
In this technical solution, optionally, after obtaining the identity information of the data provider, the method further includes:
and carrying out data uploading authority control on the data provider.
In this embodiment, the authority control may be to control the number of times the data provider uploads the shared data, may be to control the frequency of uploading the shared data by the data provider, or may be to control the size of uploading the shared data by the data provider. For example, the control data provider can upload shared data only 3 times a day.
By controlling the data uploading authority of the data provider, the quality of the shared data uploaded by the network can be improved, and the healthy development of the whole block chain data sharing network is ensured.
According to the technical scheme, shared data of a data provider are received, identity information of the data provider is obtained, encryption processing is carried out on the identity information, an encryption result is obtained, the shared data and the encryption result are transmitted to a block chain in an associated mode, voting is initiated to a member of a union associated with the shared data in response to a shared data tracing request of a data user, if the voting result meets a preset condition, a decryption algorithm is adopted to decrypt the encryption result, the identity information of the data provider is obtained, and quality monitoring is carried out.
