FIELD: physics.
SUBSTANCE: user identification method comprises detecting the user touching the sensitive area on the mobile device with a finger, collecting the fingerprint data for a predetermined time, the fingerprint data including information regarding the pattern of the ridges, the pattern of the sweat glands and the microcirculation dynamics in the finger. Next, a check is made to ensure that the resulting patterns of ridges and sweat glands are matched to the corresponding portions of the previously stored pattern samples for the user. If both received patterns correspond to the corresponding parts of the samples saved for the user, then the microcirculation dynamics in the finger is recorded. In case of successful registration of the microcirculation dynamics in the finger, the user is identified as previously recorded.
EFFECT: increasing the accuracy of the user identification of the mobile device.
