The video includes frames that each includes a user biometric characteristic image. Moreover, the method includes obtaining frames from the video and determining obtained video frames that include an optimally positioned user biometric characteristic image. The optimally positioned user biometric characteristic image is user biometric data usable for generating accurate authentication transaction results to authenticate the user. The method also includes storing the optimally positioned user biometric characteristic image included in a determined video frame in the mobile device. 29Y-axis a 1 X-axis 16 Z-axis 22 FIG. 1 Please rotate hand a 26 towards mobile 34 Ns device.
