Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic flowchart of a method according to an embodiment of the present invention, where the method for feeding back data verification information implemented in the embodiment is applied to a federation link server, and as shown in fig. 1, the method mainly includes:
In one embodiment, a federation link server may receive a user's information verification request from a federation link client.
In one embodiment, in order to improve the efficiency of determining the data verification target by the federation chain server, the information verification request may carry an intelligent contract identifier of the data to be verified, so that the federation 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 the user) which is needed by the user to verify authenticity.
In practical application, the data verification target may also be indicated by carrying other information in the information verification request, for example, number information of data analysis result information purchased by the user, and a mapping relationship between the number information and the intelligent contract may be stored in the blockchain network in advance for the league chain server to query.
It should be noted that: a federation chain is commonly established for intelligent information providers, in conjunction with a publicly trusted certification authority (ca) to issue certificates identifying the identity of each information provider (i.e., the merchant supplying the intelligent information). A user may autonomously download a client of the federation chain to request from a federation chain server to verify data in the regional chain network of the federation chain and identity information (i.e., an electronic signature value) of the corresponding information provider.
In one embodiment, the intelligent contract may identify the indicated intelligent contract as the data validation target.
And 103, acquiring intelligent contract attribute information, basic data set and basic data abstract attribute information of the data verification target from the block chain network.
Wherein the intelligent contract attribute information includes an intelligent contract and a home-side electronic signature value for the intelligent contract; the intelligent contract is code information for data analysis; the basic data set comprises homomorphically encrypted basic data; the basic data digest attribute information includes a homomorphically encrypted basic data digest and an attribution side electronic signature value of the basic data digest.
In this step, the alliance link server needs to obtain the intelligent contract attribute information, the basic data set and the basic data abstract 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 an intelligent contract, and meanwhile, the basic data is also 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 to check on the premise of not revealing original information.
In order to ensure that the original information is not leaked after the basic data and the basic data abstract are provided for the user, homomorphic encryption is required to be adopted to process the data so as to ensure the security of the data.
In addition, in this step, the electronic signature value of the attribution side of the basic data digest and the electronic signature value of the attribution side of the intelligent contract need to be obtained, so as to be provided to the user, and the user can know the authenticity of the intelligent contract used by the federation chain server for generating the data analysis result information and the authenticity of the basic data digest fed back by the federation chain server based on the electronic signature values, and further can know the authenticity of the data to be verified by using the data analysis result information and the basic data digest fed back by the federation chain server.
In one embodiment, the homomorphic 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 invention, the following detailed descriptions of the blockchain, homomorphic encryption technology and intelligent contracts are provided as follows:
block chains: the system is essentially a decentralized database, and is a string of data blocks which are associated by using a cryptographic method, and each data block contains information of service data for verifying the validity of the information.
Homomorphic encryption: a function of processing encrypted data is provided. That is, others can process the encrypted data, but the process does not reveal any of the original content. Meanwhile, the user with the key decrypts the processed data to obtain the processed result. Let us take an example in real life. A user called Alice bought a large piece of gold that she wanted to make into a necklace. However, a worker may steal gold during the manufacturing process, namely …, which is a gram of gold and much money, so that there is no method for the worker to process the gold block (missing processing of your data), but not get any gold (missing accessing to it)? Of course, Alice can do this: alice locks the gold in a closed box, which houses a glove. The worker can carry the glove to treat the gold inside the box. However, the box is locked, so that the worker cannot not only take the gold blocks, but also any gold falling off in the treatment process. And (5) finishing the processing. Alice returns the box and opens the lock to obtain the gold.
Intelligent contract: a piece of code running on top of a blockchain, a computer protocol intended to propagate, verify, or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted 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 105, feeding back the data analysis result information, the electronic signature value of the attribution party of the intelligent contract and the basic data abstract information.
Further, the alliance link server can provide basic data key point data and a value range of the key points for the user according to the information verification request, so that the user can further verify the authenticity of the purchased data analysis result information. Specifically, in one implementation, the method embodiment may further include:
acquiring and feeding back a key point attribute value and a value range attribute value of the key point of the data verification target from a block chain network; the key point attribute values are encrypted using a zero knowledge proof technique.
It should be noted that: a zero knowledge proof means that the prover can convince the verifier that some argument is correct without providing the verifier with any useful information. If a wants to prove to B that he has the key of a certain room, the room can be unlocked only by the key, but not by any other method. 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 B, thus proving that it really has the key of the room. This is a zero knowledge proof. The key proof method has the advantages that the B can not see the key appearance all the time in the whole proving process, and therefore the key is prevented from being leaked.
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 link server or not 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.
It can be seen from the above embodiment that, in the scheme, all basic data and data analysis algorithms do not need to be provided for the user, but the alliance chain server obtains pre-stored intelligent contract attribute information, basic data set and basic data abstract attribute information of a data verification target from the blockchain network, generates data analysis result information based on the information, and feeds back the data analysis result information, the electronic signature value of the intelligent contract and the basic data abstract information to the user together, so that the security of the verification information can be ensured, and the user can know the authenticity of the held data analysis result information based on the verification information on the premise of not obtaining the data analysis algorithms and all the basic data.
