A security activation method for wireless identification for controlling an electronic device system boot up includes the following steps: receiving a first identification signal, designating a corresponding first identification code as a pre-established account, transmitting a confirmation signal to a wireless transmission device corresponding to the pre-established account, receiving an authorization signal from the device, receiving a second identification signal, and comparing a corresponding second identification code with the pre-established account; if the second identification signal is the same as the pre-established account, determine whether the system accesses a boot buffer inside the electronic device; and having the following corresponding implemented actions: if the system accesses the boot buffer inside the electronic device, the system boots and transitions into operational mode; and if the system doesn't access the boot buffer, the system is shut down and receives an automatic command for system boot.
