The invention discloses a recognition method based on a brain wave, and belongs to the technical field of biological recognition. The method directly achieves the matching of an original brain wave signal with a user based on a deep learning frame, and also can achieve the brain wave signal recognition of the motion of a user at the same time, removes the existing signal processing and feature extraction operations, and greatly simplifies a conventional brain wave identity recognition model.
