This methodology involves capturing user-specific signature data through prescribed movements using sensor-equipped devices. Subsequent feature extraction and machine learning model utilization enable accurate user classification grounded on distinct sensor data patterns. The versatility of this technology spans diverse applications, offering robust solutions for secure user authentication, access control, and tailored device interactions where precise user identity verification is essential.
