Explanation of terms used in the embodiments of the present application: blockchains are a kind of chained data structures that combine blocks of data in a sequential manner in time order, and cryptographically guaranteed, non-tamperable and non-counterfeitable distributed ledgers. In broad terms, blockchain technology is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to validate and store data, distributed node consensus algorithms to generate and update data, cryptography to secure data transfer and access, and intelligent contracts composed of automated script code to program and manipulate data.
A federated chain, also known as a community blockchain (Consortium Blockchains), is a special type of blockchain that establishes partnerships among multiple parties to form a restricted access network for sharing information, data, and transactions, but allows only specific entities to participate, rather than being fully open as a public blockchain. Unlike public blockchains, participants in a federated chain are typically pre-authorized organizations or individuals. For example, a community of 15 financial institutions, each running a node, needs to be validated for 10 of the institutions in order to validate each block. Blockchains may allow everyone to read or be limited to participants only, or walk a hybrid route, such as the root hash of the block and its API (application programming interface) to be exposed, which may allow the outside world to be used for a limited number of queries and to obtain blockchain state information. These blockchains may be considered "partially decentralised".
Smart contracts are an automated compounding and mechanism based on blockchain technology, which is a piece of programming code that defines rules and behaviors that are executed under specific conditions. The main objective of smart contracts is to automatically execute the contract terms without third party intervention and to ensure the security, transparency and reliability of the transaction.
Referring to fig. 1, a flowchart of a method for implementing security of private computing data based on a federation chain according to a first embodiment of the present application is shown, where the method includes the following steps:
the data provider, the calculator and the data user are used as nodes to create a alliance chain;
the method comprises the steps that data sent by a data provider are received and uploaded to a alliance chain, computing resource information sent by a receiving computing party is received and uploaded to the alliance chain, and intelligent contract information sent by a data user is received and uploaded to the alliance chain;
receiving a data acquisition request of a data user, acquiring data information and computing resource information from a alliance chain, and sending the data information and the computing resource information to the data user;
according to a request of a user for accessing a computing party to provide services, acquiring data information from a alliance chain, sending the data information to the computing party, receiving information of model training and updating by the computing party, wherein the model can be an air control model, a marketing model, an anti-fraud model, a quantitative transaction model and the like, and the model training process comprises data preparation, feature engineering, model selection and initialization, training optimization, super-parameter adjustment, verification evaluation, iterative optimization, final deployment, continuous monitoring and the like;
triggering an intelligent contract for the request for providing services, calculating benefit distribution according to the contribution of each party in the federal modeling process, and distributing the benefit to each party;
acquiring a request of a supervisor to apply for joining a alliance chain, adding the supervisor to the alliance chain, and requiring to have read data authority and decryption authority when the supervisor applies for joining the alliance chain, so that the supervisor can be used as a member of the alliance chain to monitor data security in real time;
and acquiring information of the data security of the alliance chain of the supervision party in real time.
Prior to implementation of embodiments of the present application, the performance of federation chains and smart contracts may be evaluated through simulation and modeling methods. For example: the workflow of federation chains and intelligent contracts can be modeled using Petri nets, state machines, or other modeling tools, and their performance metrics analyzed by simulation, such as data synchronization speed, fairness of security and benefit distribution, and the like. And a alliance chain technology is adopted to ensure the data synchronization and the safety of a data provider, a data user and a calculator in the federation modeling process. The alliance chain technology can prevent data from being tampered and lost, and improves the data security.
As shown in fig. 2, a specific method for the smart contract to calculate a benefit allocation based on the contributions of parties to the federal modeling process includes:
selecting block nodes from the alliance chain link points;
reading alliance chain information according to the block outlet node, and calculating a benefit distribution result;
packing out blocks according to benefit distribution results;
broadcasting the packaged blocks;
and writing the packaged blocks into a block chain.
According to the steps, the relation between contribution and benefit distribution of each party in the federal modeling process is realized through intelligent contracts. The intelligent contract can quickly establish allocation rules, ensure that all parties execute according to the contract and accelerate the speed of joint modeling.
And for other nodes, after the step of broadcasting the packaged blocks, the other nodes receive the packaged blocks and verify the packaged blocks, and the packaged blocks are written into the blockchain after the verification is passed.
As shown in fig. 3, in this embodiment, a specific method for obtaining information of the data security of the real-time supervision alliance chain of the supervision party includes:
synchronizing all blockchain data generated by the alliance chain in the running process to a supervisor node;
and when the block chain data triggers an alarm rule, alarm information sent by the supervisor node is received.
The steps realize the automatic supervision and audit of the blockchain data by the supervision party, and the alarming information is immediately sent when the blockchain data triggers the alarming rule, so that the data safety is ensured.
The following describes the above method in detail using a specific application scenario:
a is a data provider, B is a calculator (training model providing method), C is a data user (external service provider), and three parties provide borrower risk assessment service and share service benefits through a alliance chain and intelligent contracts.

Building a risk assessment intelligent contract: on the federation chain, an intelligent contract is written, and the contract code comprises the following functions: storing the proportion of the revenue share of each party (e.g., A40%, B30%, C30%), the smart contract triggers automatic execution and proportioned revenue when the revenue enters the contract account. The intelligent contract execution process on the federation chain is visible to all parties who can verify whether the revenue distribution is made according to the contract. The supervisory side applies for joining the alliance chain, adds the supervisory side to the alliance chain, and monitors the execution process of the intelligent contracts on the alliance chain in the whole process by the supervisory side, so that the income is ensured to be carried out according to the contracts. And adding the supervision party into the alliance chain to enable the supervision party to monitor the data security in real time. Thus, the supervision party can timely discover potential data security problems and take corresponding measures for processing.
