Abstract
The present invention relates to an authentication method for electronic apparatus and authentication system, which comprises the steps of: enabling an electronic apparatus to be moved by a user from a first position to a second position; enabling an inertial sensor embedded in the electronic apparatus to detect and thus constructing a three-dimensional continuous trajectory of the electronic apparatus's movement from the first position to the second position in a Cartesian coordination system composed of a first-direction axis, a second-direction axis and a third-direction axis; and enabling a processor embedded in the electronic apparatus to perform either a process for registering the three-dimensional continuous trajectory as a standard movement trajectory; or a comparison between the three-dimensional continuous trajectory and a previously registered standard movement trajectory so as to authenticate the correctness of the three-dimensional continuous trajectory and thus authenticating the electronic apparatus.
