The content filter is a general-purpose filtering system rather than a special filtering system for special subject matter, filtered content can be obtained by learning using the training system. The filtering system is physically separated from the training system, communicates with the training system through data interface, and can be set in a network information entry device. Different filtering characters obtained by the training system are respectively assigned to the filtering system of different network information entry device with respect to filter effects of different objects. The filter of the invention realizes contents filtering by analyzing and judging text content, providing an intelligent and highly effective content security service for user.
