AI Technical Summary

Technical Problem

Existing technologies neglect the protection of the data provider's ownership of the original data during the data computation process, and do not consider the regulatory measures after the data requester obtains the data, resulting in damage to the interests of the data provider and the existence of data loss of control and potential risks.

Method used

By adopting a data trust computing framework based on consortium blockchain, data is standardized and registered by dividing it into three parts: identifier, feature data, and data entity. A data trust computing mechanism and traceability mechanism are designed to realize data processing as a service, ensuring that data providers can provide data analysis results without data requesters having access to the original data, and ensuring the security and integrity of data flow through on-chain traceability.

Benefits of technology

It ensures data security and control for data providers, prevents data leaks, rebuilds trust relationships in the data computation process, alleviates data barriers and loss of control issues, and ensures that data requesters obtain analysis results while protecting the interests of data providers.

Abstract

The application provides a data trusted computing framework based on a consortium blockchain, entities include a data demander, a data provider, a consensus node and a certificate authority; a structure is divided into a data registration layer, a data trusted layer, a data consensus layer, a data processing layer and a data delivery layer. The data registration layer adopts a data architecture paradigm based on the consortium blockchain, divides data into identification, characteristic data and data entities to standardize a data registration process, provides a unified access mode for heterogeneous, heterogeneous and heterogeneous data resources and integrates data resources; the data trusted layer uses a data trusted computing mechanism, so that the data provider provides a data resource analysis and processing result for the data demander without contacting original data; the data consensus layer includes a data trusted traceability mechanism, guarantees safety and integrity of data flow; the application can change a traditional data hosting / exchange as a service mode into a data processing as a service mode and realizes data "available but invisible".
