Abstract

The invention discloses a large data collection transaction system based on a block chain and a trusted computing platform, including: an address verification module on the user chain, a data collection module, a data upload module, a data credibility verification module and a data remuneration payment module . The system solves the problem of shortage of data sources by integrating large-scale personal data islands, and implements all-round supervision and protection of data collection, storage, packaging, and uploading operations, realizing full-link trustworthiness of data and direct use The method of anonymous proof enables the data collection company to protect the privacy of users when authenticating the validity of the public key address on the user chain; and, based on the characteristics of decentralization and automation of blockchain smart contracts, it ensures the openness and transparency of data reward payment, thereby To a certain extent, it reconciles the contradiction between personal privacy protection and big data collection, and ensures the credibility of data sources. At the same time, it is practical and easy to implement.

Description

technical field [0001] The invention relates to the technical field of cloud computing security, in particular to a big data collection and transaction system based on a block chain and a trusted computing platform. Background technique [0002] In recent years, with the rapid development of multimedia technology, software technology and storage technology, technologies such as big data and machine learning have profoundly affected and changed social production and lifestyle, but reliable data sources are the prerequisite for the implementation, operation and development of these technologies. The popularity of IoT devices provides a solution to the shortage of big data sources. Large-scale IoT devices can collect various data with economic analysis value such as personal location tracking record data, personal health data, personal living habits and preference data, but How to ensure the fairness and credibility of data transactions and the privacy of data providers is curr...
