Online data ecology is not only complex and diverse, data derived from the users’ behavior also continue to develop new features, which put forward higher requirements to protect the personal information. The study argued that, to effectively protect personal information on the Internet,we need to understand the two-wayinteractive mechanism between companies’data behavior and users’Internet participation, then grasp the risks that may occur in every aspect of the interactive process.
