User location check method, controlled device access method, controlled device, and user terminal

A controlled device for establishing a wireless network connection, the controlled device comprising one or more processors, memory coupled to the one or more processors, and a plurality of programs stored in the memory that, when executed by the one or more processors, cause the mobile terminal to perform operations including:

• dynamically generating a first security code, wherein the first security code is a randomly generated alphanumerical string including a link address;
• periodically broadcasting the dynamically generated first security code repeatedly within a predefined time window;
• receiving a second security code and a user account identifier from a remote server, wherein the remote server receives the second security code and the user account identifier from a mobile terminal after the mobile terminal obtains the dynamically generated first security code through the broadcasting and forwards the second security code to the controlled device according to the link address in the dynamically generated first security code;
• checking whether the received second security code is consistent with the dynamically generated first security code;
• and
• determining that a user location check succeeds only in accordance with a determination that the received second security code is consistent with the dynamically generated first security code and performing a predefined operation associated with the user account identifier.

A non-transitory computer readable storage medium storing a plurality of programs that, when executed by one or more processors of a controlled device, cause the controlled device to perform operations including:
