<p>The present subject matter discloses device and method determining legitimacy of user. A detecting module detects fingers swept in a sequence by a user on the fingerprint sensor 102. The determining module 114 determines: a pressure applied, while sweeping, corresponding to the two or more fingers, a time duration corresponding to the sweeping of each of the two or more fingers, and a time gap between the sweeping of a finger and a subsequent finger, of the two or more fingers, in the sequence. Matching module 116 matches the sequence, the pressure, the time duration and the time gap with a reference sequence, a reference pressure, a reference time duration and reference time gap, respectively, associated with the user. The generating module 118 generates a score based on the matching. Further, the determining module 114 determines the legitimacy of the user based upon comparison of the score with a threshold.</p> |
