Embodiment Construction

[0044] In the auditing process provided in this specification, the auditing target is each computing party performing secure multi-party computation. The audit process can be started according to the received audit request for the query result, which can be determined according to secure multi-party computation.

[0045] In the existing secure multi-party computing method, each computing party participating in the calculation can send each encrypted data obtained after encrypting the original data to other computing parties. Similarly, for each calculation party, the calculation party can also receive encrypted data sent by other calculation parties, and after passing the secure multi-party calculation, any calculation party can restore the original data of other calculation parties, The comprehensive data corresponding to the original data of each computing party is obtained. In order to audit each computing party in the secure multi-party computation, each computing party c...

Abstract

This application discloses a method and device for data auditing. For each computing node, when performing secure multi-party computing according to a query request, encrypted data received from other computing nodes and / or encrypted data generated by itself can be used as Data to be audited is stored in a trusted storage space. So that if the agent receives an audit request for the query result corresponding to the query request, the agent can, according to the key obtained from each computing node, check the encrypted data contained in the data to be audited obtained from the trusted storage space Perform decryption processing to obtain the original data of each computing node. And audit each computing node according to each original data.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and device for data auditing. Background technique [0002] As a supervisory mechanism, audit plays an important role in modern society. At present, with the development of the network, the types of audited content are also increasing. For example, audit the insurance situation of the user in the insurance company, audit the loan situation of the user, audit the assets of the user, and so on. The service provider can determine whether to provide services to users or what kind of services to provide based on the audit results. [0003] Due to the openness of the market, there may be multiple service providers for the same service in the market. However, a user can execute the same service at multiple service providers that provide the service, so that each service provider executes the same service for the same user, that is, a multi-head type service. ...
