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

The invention discloses a method and a device for data auditing. For each computing node, received encrypted data sent from other computing nodes and/or encrypted data generated by the computing nodecan be stored in a trusted storage space as data to be audited when secure multi-party computation is carries out according to a query request. Thus, if an agent receives an auditing request for a query result corresponding to the query request later, the agent can acquire the encrypted data contained in the data to be audited from the trusted storage space for decryption processing according to secret keys acquired from the computing nodes, so as to obtain original data of the computing nodes, and conduct auditing on the computing nodes according to the 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. ...
