The block chain is a technical system which is jointly maintained by multiple parties, stores data in a block chain structure, uses cryptography to ensure transmission and access safety, and can realize consistent storage of the data and cannot be tampered. Specifically, a blockchain is a permanent, non-reversible modified data record generated by superimposing encrypted data or blocks in chronological order. From a technical level, the blockchain involves many scientific and technical problems such as mathematics, cryptography, internet and computer programming. From the application aspect, the blockchain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace leaving in the whole process, traceability, collective maintenance, openness and transparency and the like.

The privacy calculation is a technical system for realizing data value mining on the premise of providing privacy protection. In the face of each participating node of data calculation or an attacker intending to steal information, the privacy calculation technology can realize calculation of data related to calculation in an encrypted state or a non-transparent state so as to achieve the purpose of privacy protection of each participating node. The block chain has the advantages that data is open, transparent and shared, but some block chain users do not want to expose their private information for the upper application scenes of the block chain. For such situations, the existing solution combines privacy computation and a blockchain technique, and provides a safe and private solution for an upper application scenario of a blockchain.

Exemplarily, the prior art provides a block chain-based distributed privacy computing method and device, and the device is designed as a block chain infrastructure layer, a distributed parallel computing layer and an interface display layer, and the technical scheme includes that a computing request client issues a computing task and decomposes the computing task; the task distribution module distributes tasks, and the computing node returns a task claim confirmation message; the calculation request client side compiles a benefit distribution intelligent contract; the computing node downloads the training model for training and returns the result to the computing request client; the safety verification module verifies the result returned by the computing node and fuses the result to obtain a final federal model; the intelligent contract distributes benefits to each computing node by using a benefit distribution function.

The existing scheme has the following defects: firstly, in the scheme, benefit distribution is carried out on each computing node by calling a distribution function through an intelligent contract, and the intelligent contract for writing the benefit distribution is formulated according to the benefit distribution function and the contribution amount of each computing node. However, the contribution amount of each computing node does not store the task completion condition, so that the problem of unclear task completion condition statistics exists, and the benefit distribution in the privacy computing process is unbalanced. Secondly, the abnormal state of the privacy computation task on the block chain is not monitored and managed in the scheme, and the behavior of each node participating in the privacy computation cannot be effectively normalized.

Therefore, in summary, in the current technical solution of combining the blockchain and the privacy computation, it is mainly concerned that how the privacy computation itself provides a computing environment with privacy security, or only the blockchain intelligent contract is used to distribute benefits to each node, and the non-tamper property of the blockchain is not used to supervise and audit all parties of the privacy computation, nor is the usage amount of the data stored to implement subsequent mechanisms such as pricing and charging, and further supervision and fine management on the data usage are lacked.

In order to solve the problems that benefit distribution is unbalanced and behaviors of all participated nodes of privacy calculation cannot be effectively normalized when the privacy calculation is combined with a block chain technology in the current stage, the privacy calculation evidence storage method is provided so as to achieve balanced benefit distribution and normalized management of all participated nodes in the privacy calculation process.

Illustratively, as shown in fig. 1, a system architecture diagram of a private computing presence system is provided herein. The privacy computing verification system 10 includes: a first node 11, a second node 12, a block link point 13.

The first node 11 is a node initiating a privacy computation task in a privacy computation process. Specifically, the first node 11 starts the privacy calculation process by sending a privacy calculation request to the second node 12. Meanwhile, the first node 11 sends task feature information of the private computation task to the block link node.

The second node 12 is a node participating in the privacy computation task in the privacy computation process. Correspondingly, after receiving the privacy computation request sent by the first node 11, the second node 12 authenticates the privacy computation request by acquiring the task feature information of the privacy computation task stored on the blockchain node 13, and participates in the privacy computation task if the authentication is passed. It should be noted that after participating in the privacy computation task, the second node 12 uploads the relevant result information of the privacy computation task to the blockchain node 13.

And the block chain node 13 is used for storing task characteristic information of the privacy calculation task and result information of the privacy calculation, and bearing the responsibility of determining a payment strategy to realize balanced benefit distribution. In addition, the block link point 13 determines the credit level of each participating node according to the stored historical privacy calculation result information, so as to supervise each participating node and realize the standard management in the privacy calculation process.

In different application scenarios, the first node 11, the second node 12, and the block chain node 13 may be disposed in different devices included in the privacy computing deposit system 10, or may be integrated in the same device included in the privacy computing deposit system 10, which is not specifically limited in this application.

When the first node 11, the second node 12 and the block link point 13 are integrated in the same device in the privacy computing and evidence storing system 10, the communication mode among the first node 11, the second node 12 and the block link point 13 is the communication among internal modules of the device. In this case, the communication flow among the three nodes is the same as "the communication flow among the three nodes when the first node 11, the second node 12, and the block link point 13 are independent of each other".

The system architecture of the privacy computing evidence storing method provided by the application is introduced above.

The technical solution provided by the present application is specifically explained below with reference to the drawings of the specification.

Illustratively, as shown in fig. 2, the privacy computing evidence storing method provided by the present application specifically includes the following steps S201 to S213:

it should be noted that, in the privacy computing and evidence storing scheme provided in the present application, the number of the second nodes may be multiple. In fig. 2, the number of the second nodes is only one for exemplary illustration, and does not represent that the technical solution of the present application is only applicable to the case where the number of the second nodes is only one.

S201, the first node determines task characteristic information.

The first node is a node initiating a privacy computation task. The task characteristic information is the characteristic information of the privacy computation task. It is understood that the privacy computation task herein is a computation task involved in providing privacy computation services for blockchain users when combining blockchain and privacy computation technologies.

Optionally, the task feature information of the privacy computation task may include one or more of: and data description information, a timestamp, a participating node name and configuration parameter information of the privacy calculation task.

S202, the first node sends task characteristic information to the block chain nodes. Accordingly, the block link node receives task feature information from the first node.

The first node sends the task feature information to the blockchain link point, so as to verify the feature information of the privacy computation task on the blockchain. In this way, other privacy computation participating nodes can download the task feature information through the block chain nodes, and compare the task feature information with the received task feature information from the first node, so as to facilitate the privacy computation request through the first node when the two feature information are consistent.

S203, the first node sends a privacy calculation request to the second node. Accordingly, the second node receives a privacy computation request from the first node.

And the second node is a node participating in the privacy calculation task. The privacy computation request is a request message initiated by the first node for instructing the second node to participate in the privacy computation task. Wherein the privacy computation request comprises task characteristic information of the privacy computation task,

s204, the second node judges whether the privacy calculation request passes according to task characteristic information included in the privacy calculation request.

In one possible implementation, the second node compares the received task characteristic information from the first node with the task characteristic information of the privacy computation task downloaded from the block link point. Further, if the comparison result is inconsistent, the second node determines that the privacy computation request fails, and executes the following step S205; if the comparison result is consistent, the second node determines that the privacy computation request passes, and then executes the following step S206.

S205, the second node sends the request failure information of the privacy computation task to the block chain node. Accordingly, the tile chain node receives request failure information for the private computing task from the second node.

Optionally, the second node generates request failure information of the privacy computation task after determining that the privacy computation request fails. The request failure information records a judgment process that the second node fails to pass the privacy calculation request. Illustratively, the request failure information may be a kind of log information.

S206, the second node sends the calculation result information of the privacy calculation task to the block chain nodes. Accordingly, the tile chain node receives the computation result information of the private computation task from the second node.

Optionally, after determining that the privacy computation request passes, the second node participates in executing the corresponding privacy computation task, records the computation result of the privacy computation task, and generates the computation result information.

Optionally, the computation result information of the privacy computation task comprises one or more of: the corresponding log hash value, the task state, the calculation result, the target data use mode, the target data volume, the target data calling times and the target data calling result of the privacy calculation task; and the target data is data required by the privacy calculation task.

It can be understood that the second node uploads the calculation result information of the privacy calculation task to the block chain node, so as to perform a higher-reliability evidence storage on the privacy calculation process. And the subsequent block chain node can conveniently carry out trust rating on the first node and the second node according to the calculation result information, so that the first node and the second node can be supervised, and the behavior of each participating node in privacy calculation can be normalized.

S207, the block chain link point sends first indication information to the first node. Accordingly, the first node receives the first indication information from the blockchain node.

The first indication information is used for indicating the first node to determine first feedback information, and the first feedback information is used for indicating the blockchain node to make a payment strategy.

S208, the first node sends the first feedback information to the block chain node. Accordingly, the block link node receives the first feedback information.

In one possible implementation, the block chain node sends first indication information for making a payment policy to the first node based on a consensus mechanism in the block chain technology. Correspondingly, after receiving the first indication information, the first node performs voting operation on the payment policy based on a consensus mechanism in the blockchain technology, and generates first feedback information based on the voting operation. After that, the first node sends the first feedback information to the blockchain node so that the blockchain node acquires the voting opinions of the first node on the payment strategy.

In another possible implementation, the first node may preset factors that affect the payment policy. For example, the first node presets factors influencing the payment policy, which may include: providing credit levels of the participating nodes of the target data, a target data using mode, a target data amount, target data calling times and a target data calling result; and the target data is data required by the privacy calculation task. In this way, after receiving the first indication information, the first node may determine the first feedback information according to a preset factor affecting the payment policy, so that the blockchain node obtains the voting opinion of the first node on the payment policy.

S209, the block chain node sends second indication information to the second node. Accordingly, the second node receives second indication information from the blockchain node.

The second indication information is used for indicating the second node to determine second feedback information, and the second feedback information is used for indicating the blockchain node to make a payment strategy.

S210, the second node sends second feedback information to the block chain node. Accordingly, the blockchain node receives the second feedback information.

In one possible implementation, the block link point sends the second indication information for making the payment policy to the second node based on a consensus mechanism and an intelligent contract in the block chain technology. Correspondingly, after receiving the second indication information, the second node performs voting operation on the payment policy based on a consensus mechanism in the blockchain technology, and generates second feedback information based on the voting operation. After that, the second node sends the second feedback information to the blockchain node so that the blockchain node acquires the voting opinions of the second node on the payment strategy.

In another possible implementation, the second node may preset factors that affect the payment policy. For example, the second node presets factors influencing the payment policy, which may include: providing credit levels of the participating nodes of the target data, a target data using mode, a target data amount, target data calling times and a target data calling result; and the target data is data required by the privacy calculation task. In this way, after receiving the second indication information, the second node may determine the second feedback information according to a preset factor affecting the payment policy, so that the blockchain node obtains the voting opinion of the second node on the payment policy.

S211, determining a payment strategy by the block chain node according to the first feedback information and the second feedback information.

It is understood that, as described in the foregoing S208 and S210, after receiving the first feedback information of the first node and the second feedback information of the second node, the blockchain node determines the final payment policy according to the voting opinions of the first node and the second node on the payment policy. It should be noted that, the specific block link points determine the final payment policy according to the voting opinions of the first node and the second node on the payment policy based on the consensus mechanism, which is the prior art and is not described herein again in this embodiment.

It should be noted that, through the above S208-S211, the first node, the second node, and the block link point jointly make a payment policy in the privacy computation process through signaling interaction. In addition, the first node, the second node and the block chain nodes can automatically adjust the pricing of the target data in the payment strategy according to the related information of the historical privacy calculation tasks recorded on the block chain through intelligent contracts. Or the first node, the second node and the block link point can automatically complete the payment of the target data through an intelligent contract.
