Abstract：With the development of communication and network technologies， such as Internet， cloud computing， and the Internet of Things， cross-boundary flow and storage of data become more convenient. In the era of big data， national data security is facing more severe challenges. Data sovereignty will become the theoretical foundation of national administration of data and data-related technologies， facilities and service providers. In practice， unfortunately， the spontaneous game between nations results in a multi-jurisdictional conflict and chaotic national security dilemma. With the purpose of solving the dilemma， the international community should focus on data sovereignty with the concepts of participation and cooperation. Specifically， data jurisdiction should be based on territorial jurisdiction and personal jurisdiction. All countries around the world take collective actions to confront criminal actions in cyberspace in order to realize common security and development．
