A method for obtaining a confirmation of a permission to control a terminal to be bound by a current account at a network-side server; the method comprising: sending (S202), from a control terminal to the network-side server, via the current account, a binding request for binding the terminal to be bound to the current account; determining, by the network-side server, a detectable physical property of the terminal to be bound according to a physical feature which the terminal to be bound has, the physical feature which the terminal to be bound has, being a display screen, an indicator light or a physical button; sending, from the network-side server to the control terminal, a binding operation prompt relating to the determined detectable physical property; executing (S101) by the control terminal a binding verification operation in response to the binding operation prompt relating to the physical property; wherein the binding verification operation consists in detecting on the terminal to be bound verification information relating to the detectable physical property; reporting (S102), by the control terminal, the verification information relating to the detectable physical property of the executed binding verification operation to the network-side server; verifying, (S403) at the network-side server, a validity of the reported verification information; sending (S404), from the network-side server, a binding result to the control terminal according to a verification result of said verifying the validity of the reported verification information; ; and establishing at the control terminal a control relationship between the current account at the network-side server and the terminal to be bound if the binding result is successful, and consequently the current account obtaining the confirmation of the permission to control the terminal to be bound; or displaying at the control terminal a binding failure prompt if the binding result is failing. sending (S202), from a control terminal to the network-side server, via the current account, a binding request for binding the terminal to be bound to the current account; determining, by the network-side server, a detectable physical property of the terminal to be bound according to a physical feature which the terminal to be bound has, the physical feature which the terminal to be bound has, being a display screen, an indicator light or a physical button; sending, from the network-side server to the control terminal, a binding operation prompt relating to the determined detectable physical property; executing (S101) by the control terminal a binding verification operation in response to the binding operation prompt relating to the physical property; wherein the binding verification operation consists in detecting on the terminal to be bound verification information relating to the detectable physical property; reporting (S102), by the control terminal, the verification information relating to the detectable physical property of the executed binding verification operation to the network-side server; verifying, (S403) at the network-side server, a validity of the reported verification information; sending (S404), from the network-side server, a binding result to the control terminal according to a verification result of said verifying the validity of the reported verification information; ; and establishing at the control terminal a control relationship between the current account at the network-side server and the terminal to be bound if the binding result is successful, and consequently the current account obtaining the confirmation of the permission to control the terminal to be bound; or displaying at the control terminal a binding failure prompt if the binding result is failing. <EOS>
