Abstract: The present invention discloses an identification system which includes an image sensor, a storage unit and a comparing unit. The image sensor captures a plurality of images of the motion trajectory generated by a user at different timings. The storage unit has stored motion vector information of a group of users including or not including the user generating the motion trajectory. The comparing unit compares the plurality of images with the motion vector information to identify the user. The present invention also provides an identification method.
