In recent years， the rapid development of Internet of Things （IoT） has spurred the emergence of the Internet of Behavior （IoB）， which leverages IoT-derived data and information to achieve higher levels of knowledge and wisdom， rapidly evolving into a promising technology in various application potential. IoB involves extensive collection， processing， and utilization of user behavioral data， thereby exposing user data security and privacy to significant risks. Therefore， it is vital to protect the IoB user data with effective data management and control. After introducing the fundamental concepts and characteristics of IoB， its development trends and the security and privacy risks associated with user data were analyzed. Furthermore， the current situation of management and control of behavioral data was elaborated， the main problems and challenges existed in IoB were discussed， and the potential research directions to achieve user data management and control in IoB were proposed.
