The invention provides a method and system for identifying a WIFI hotspot service. Before a user side and a WIFI hotspot device are successfully connected, a local service is in an encrypted state, and thus the local service can be prevented from being stole; before connection, the WIFI hotspot device continuously monitors the WIFI connection status of the user side, and when the user side enables a WIFI function, information that the WIFI hotspot device expects to connect with the user side preferentially is received at first time, thereby improving the success rate of connection of the WIFI hotspot device with the user side; and after connection succeeds, the WIFI hotspot device opens the local service to the user side. Through the abovementioned method, whether the WIFI hotspot device is connected with the internet or not, the user side can use the local service, and resources of the local service are not occupied, so that the user side can conveniently and smoothly use the local service.
