Method and device for data auditing

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. ...

Problems solved by technology

[0009] The embodiment of this specification provides a method and device for data auditing, which is used to solve the problem that in the existing multi-head type business, it is difficult to verify the data of the multi-head type because the user's business data at each computing node belongs to the privacy data of each computing node itself. business audit issues
