Disclosed is a crowd sensing method, comprising: a cloud platform sending a data collection request message to a first terminal, the data collection request message being used for requesting a message of data collection; the cloud platform acquiring a data collection request response message sent by a terminal of a tail node, the data collection request response message sequentially comprising a message of data collected by a terminal of each node, the nodes comprising nodes used for collecting data and determined according to an original task of the cloud platform. Thus, the sending of device information and current position information about a terminal to a cloud platform is avoided while the terminal collects data, thereby preventing personal information about the terminal from being leaked, and further enhancing the security of the terminal. |
