Detailed Description
The present application will be described in further detail with reference to the drawings and the embodiments, in order to make the objects, technical solutions and advantages of the present application more apparent.
Fig. 1 is a schematic flow chart of a method of an embodiment of the present application, and a feedback method of data verification information implemented in the embodiment is applied to a federated chain server, as shown in fig. 1, and mainly includes:
step 101, receiving an information verification request.
In one embodiment, the federated chain server may receive a user's information verification request from a federated chain client.
In one embodiment, to improve the efficiency of determining the data verification target by the federated chain server, the information verification request may carry an intelligent contract identifier of the data to be verified, so that the federated chain server may determine the data verification target.
The data to be verified is data analysis result information (such as business intelligence information purchased by a user) for verifying authenticity of the user.
In practical application, the data verification target may be indicated by carrying other information in the information verification request, for example, the number information of the data analysis result information purchased by the user, and the mapping relationship between the number information and the intelligent contract may be pre-stored in the blockchain network for the alliance chain server to query.
It should be noted that: a federation chain is co-organized for intelligent information providers, which in conjunction with a trusted authentication center (ca) issues certificates to designate the identity of the individual information providers (i.e., merchants that supply the intelligent information). The user may autonomously download the client of the federation chain to request verification of data in the regional chain network of the federation chain and identity information (i.e., electronic signature values) of the corresponding information provider from the federation chain server.
Step 102, determining a data verification target based on the information verification request.
In one embodiment, the smart contract indicated by the smart contract identification may be determined as the data verification target.
And step 103, acquiring intelligent contract attribute information, basic data set and basic data abstract attribute information of the data verification target from a blockchain network.
Wherein the intelligent contract attribute information comprises an intelligent contract and a home electronic signature value of the intelligent contract; the intelligent combination is about code information for data analysis; the basic data set comprises homomorphic encrypted basic data; the basic data abstract attribute information comprises a homomorphic encrypted basic data abstract and a attribution party electronic signature value of the basic data abstract.
In this step, the federated chain server needs to obtain the intelligent contract attribute information, the basic data set, and the basic data summary attribute information of the data verification target from the blockchain network.
The code information for data analysis is stored in the blockchain network in the form of intelligent contracts, and meanwhile, the basic data is stored in the blockchain network after homomorphic encryption, so that the alliance chain server can calculate and obtain data analysis result information based on the information and provide the data analysis result information for a user for verification on the premise of not revealing the original information.
In order to ensure that the original information is not revealed after the basic data and the basic data abstract are provided for users, homomorphic encryption is needed to process the data so as to ensure the safety of the data.
In addition, the step of acquiring the attribution electronic signature value of the basic data abstract and the attribution electronic signature value of the intelligent contract is to provide the electronic signature values for the user, so that the user can acquire the authenticity of the intelligent contract for generating the data analysis result information by the alliance chain server and the authenticity of the basic data abstract fed back by the alliance chain server based on the electronic signature values, and further the authenticity of the data to be verified can be acquired by utilizing the data analysis result information and the basic data abstract fed back by the alliance chain server.
In one embodiment, the homomorphically encrypted base data may be all or part of the base data used by the data analysis algorithm.
For the purpose of clearly illustrating the technical effects of the present application, the following details of the blockchain, homomorphic encryption techniques and smart contracts used in the present application are as follows:
blockchain: essentially, a decentralised database is a series of data blocks generated by association using cryptography, each data block containing information of service data for verifying validity of the information.
Homomorphic encryption: a function of processing encrypted data is provided. That is, other people can process the encrypted data, but the process does not reveal any original content. Meanwhile, after the user with the secret key decrypts the processed data, the processed result is obtained. We take an example of real life. A user called Alice purchased a large piece of gold that she wanted to make a necklace from the worker. However, the worker may steal the gold during the process of making, after all, …, which is a gram of gold and a lot of money, cannot be a method for the worker to process the gold block (delegate processing of your data), but cannot obtain any gold (without giving away access to it)? There is of course a way Alice can do this: alice locks the gold in a closed box that holds a glove. The worker can carry the glove and process the gold seeds inside the box. However, the box is locked, so that workers cannot take the gold blocks, and any gold falling in the processing process cannot be taken. After the processing is completed. Alice takes back the box and opens the lock to obtain the gold.
Intelligent contract: a piece of code running on top of the blockchain, a computer protocol that aims to propagate, verify or execute contracts in an informative manner. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible.
And 104, generating data analysis result information based on the intelligent contract and the basic data set.
And step 105, feeding back the data analysis result information, the attribution side electronic signature value of the intelligent contract and the basic data abstract information.
Furthermore, the alliance chain server can provide basic data key point data and the value range of the key points for the user according to the information verification request so as to further verify the authenticity of the purchased data analysis result information. Specifically, in one implementation manner, the method embodiment may further include:
acquiring and feeding back a key point attribute value and a value range attribute value of a key point of the data verification target from a block chain network; the key point attribute value is encrypted using a zero knowledge proof technique.
It should be noted that: zero knowledge proof refers to the ability of a prover to trust that a certain assertion is correct without providing the verifier with any useful information. If a were to prove to B that it had a key for a room that could only be unlocked with the key, but not in any other way. B determines that there is an object in the room, A opens the door of the room with its own key, and then takes the object out to show it to B, thereby proving that it really has its own key. This is a zero knowledge proof. The key has the advantages that in the whole proving process, B can not see the key all the time, so that the leakage of the key is avoided.
In the method, the key points encrypted by the zero knowledge proof technology and the value range of each key point are obtained, so that a user does not need to see all basic data, and whether the key points in the analysis result information of the data to be verified are in the corresponding value range fed back by the alliance chain server is judged based on the value range of the key points, and the authenticity of the analysis result information of the data to be verified can be obtained.
According to the embodiment, all basic data and data analysis algorithms are not required to be provided for a user in the scheme, but the alliance chain server acquires intelligent contract attribute information, basic data set and basic data abstract attribute information of a data verification target stored in advance from the blockchain network, generates data analysis result information based on the information, and feeds back the data analysis result information, the attribution electronic signature value of the intelligent contract and the basic data abstract information to the user together, so that the safety of the verification information can be ensured, and the user can acquire the authenticity of the held data analysis result information based on the verification information on the premise that the data analysis algorithm and all basic data are not acquired.
