Method for preventing unintended touch input of terminal, and terminal

A method for preventing an unintended touch input of a terminal, and a terminal. The method comprises: detecting a touch operation inputted by means of a touch screen of a terminal and obtaining a touch parameter of the touch operation (S101); judging whether the touch parameter matches a preset touch parameter (S102); and if the touch parameter matches the preset touch parameter, determining that the touch operation is an invalid operation, and not responding to the touch operation (S103). The method can effectively reduce the probability of a terminal being accidentally operated.
