It refers to the characteristics that the information dissemination and specific content circulating in the network system can be effectively controlled, that is, any information in the network system should be controllable within a certain transmission range and storage space. In addition to the conventional monitoring of communication sites and communication contents, the most typical hosting strategies, such as passwords, must be strictly controlled and implemented when the encryption algorithm is managed by a third party.
