The method involves determining sequence of instruction randomly, and sending the instruction to a user. A response is received from the user. Analysis for validation of the instruction is performed, where the instruction is to be validated when the response is a valid response for the instruction and a time elapsed between sending of the instruction and receiving of the response is shorter than a set period. A mechanism is not activated if the instruction is not validated. The next instruction is sent after validation. The mechanism is activated when the last sent instruction is validated. An independent claim is also included for a device for activating a mechanism. |
