Embodiment

[0060] After the data provider is registered on the platform, it needs to download the pricoco client and run it on the server where the client is located. After submitting a certain deposit for the account, when two or more parties perform MPC operations, the pricoco platform will from time to time. Conduct a status inspection to check whether the calculation parties comply with the platform rules. If cheating is found, the account will be frozen and the deposit provided will be confiscated.

[0061]This system is mainly composed of three systems: merchant registration, deposit service, and platform system verification.

[0062] Merchant registration: Merchants register as MPC computing merchants on the platform, add corresponding labels and descriptions to display the data services they can provide, and merchants must provide their public key data information during registration.

[0063] Deposit service: If a registered merchant wants to provide data calculation, a correspo...

Abstract

The invention provides a data source screening method and system for preventing a commercial tenant from behaving based on zero-knowledge proof, and the method comprises the steps: 1, generating a random value on a privacy computing platform, and transmitting the random value to a commercial tenant server in an HTTPS mode; 2, in a merchant server, generating a corresponding calculation result value and a zero knowledge proof according to the random value; 3, sending the calculation result value, the zero-knowledge proof and the process data to a privacy calculation platform; and 4, in the privacy computing platform, verifying the computing result value and the zero-knowledge proof, and if the verification result does not meet the preset requirement, correspondingly punishing the merchant. Through the verification of the invention, the platform can check the commercial tenants performing privacy calculation according to the public keys provided by the commercial tenants, so as to improve the discourse cost of the commercial tenants, improve the management capability of the platform and the quality of data provided by the commercial tenants, and enable the commercial tenants to be more real and credible in the aspect of privacy data calculation.

Description

technical field [0001] The invention relates to the technical field of data source screening, in particular to a data source screening method and system for preventing merchants from doing evil based on zero-knowledge proof. Background technique [0002] sacre is a privacy computing platform, which provides two or more parties to conduct private data interactive computing in a safe and credible environment on the premise that the data of each merchant is not local. The platform will incentivize the calculation between merchants with points. Points can improve the search priority of merchants on the platform and can occupy better resources on the platform. [0003] Some merchants will perform disguised calculations on the platform, and obtain the platform's point rewards under the premise of invalid calculations to improve their rankings. [0004] Patent document CN114172655A (application number: CN202111310563.7) discloses a secure multi-party computing data system, method,...
