Abstract: Various embodiment provide a multi-terminal cooperative working method, a terminal device, and a multi-terminal cooperative system. In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.

Abstract: This application provides a method for secure multi-terminal cooperative working, applied to a network on which a plurality of terminal devices perform cooperative playing and/or cooperative recording, where the plurality of terminal devices include a first terminal device. The method includes: determining, by the first terminal device, a security mechanism; obtaining, by the first terminal device, cooperative working information, where the cooperative working information is information played and/or recorded by the plurality of terminal devices; and performing, by the first terminal device, security processing on the cooperative working information based on the security mechanism. After obtaining the cooperative working information, the first terminal device performs security processing on the cooperative working information based on the security mechanism, so that a process other than the cooperative working process cannot access the cooperative working information, thereby ensuring security of the cooperative working information.
