Privacy Protection Technology in IOT Data Storage Based on Blockchain

The so-called Internet of things refers to connecting many objects in reality and existing on the network structure in a specific form. With the development of the Internet of things technology, the types of data collected in the Internet of things are increasing and the data scale is expanding. The traditional data storage system is no longer applicable. In order to effectively store and use these data, a new data storage system is needed to manage the information collected in the Internet of things. This paper proposes a data storage system of the Internet of things based on the blockchain, then analyzes the functions of various privacy protection technologies and their protection effects on the system, and forecasts the development direction of privacy protection technologies in the future data storage system of the Internet of things.
