Abstract
With the rapid development of mobile Internet, the application environment of data information is becoming more and more complex. How to prevent the leakage of sensitive data has become an urgent practical problem to be solved in the field of information security. In this situation, data leakage protection (DLP) technology emerges, its aim is to protect sensitive data in all directions and to establish a security protection mechanism covering the whole data life cycle. Starting from the research background and basic concepts of data leakage protection, this paper reviews and summarizes the current research status and development trend of data leakage protection technology.
