System and method for data exchange by using distributed ledger

Abstract

Disclosed are a system and method for data exchange by using a distributed ledger. Data is exchanged outside the chain, and information used to access data outside the chain is exchanged through the blockchain. Embodiments can provide a hybrid blockchain data exchange platform that stores large amounts of data (such as IoT data) in a data server outside the blockchain. Data consumers can use tokens obtained from the blockchain to obtain data from the data server. The embodiment of the hybrid blockchain data exchange platform provides data accuracy and security. There is no need to store the entire content of the data in the blockchain and / or ensure the irrefutable nature of the exchanged data.

Description

technical field [0001] The present invention relates to data exchange between data providers and data consumers, and in particular to data exchange using distributed ledgers. Background technique [0002] The Internet of Things (IoT) is a system of interconnected computing devices, mechanical and digital machines, objects, animals or people with unique identifiers (UIDs) capable of transmitting data over a network without human-to-human or human-to-machine interact. With the widespread adoption of connected devices such as smart appliances, cameras, voice-controlled personal assistants, smartphones, sensors, etc., IoT systems are being widely used. Accordingly, large amounts of IoT data (eg, sensor data, captured video and / or audio, transaction data, etc.) are generated. These diverse and robust IoT data can be used by multiple data consumers (e.g. individuals, commercial enterprises, government departments, researchers, security forces, etc.) , targeting advertising and ...
