1. A user authentication device, comprising:
- an input sensing module comprising a sensing surface with which a palm of a user is placed in contact to provide input palm information, the sensing surface having a three-dimensional shape; and
a control module configured to compare the input palm information sensed by the input sensing module with stored user palm information to output an authentication signal when a number of data points of the input palm information consistent with the stored user palm information is equal to or greater than a predetermined number,wherein the stored user palm information comprises lengths of fingers, shapes of fingers, widths of finger knuckles, lengths of palm lines, shapes of palm lines, lengths between the finger knuckles adjacent to each other, and associative relations between the finger knuckles corresponding to each of other adjacent fingers.

10. A method of authenticating a user, comprising:
-
sensing an input by a palm of the user, which occurs by placing the palm of the user in contact with a sensing surface of an input sensing module to provide input palm information, the sensing surface having a three-dimensional shape; comparing the input palm information sensed from the input sensing module with user palm information previously stored in a memory; and generating an authentication signal when a number of data points of the input palm information consistent with the stored user palm information is equal to or greater than a predetermined number, wherein the stored user palm information comprises lengths of fingers, shapes of fingers, widths of finger knuckles, lengths of palm lines, shapes of palm lines, lengths between the finger knuckles adjacent to each other, and associative relations between the finger knuckles corresponding to each of other adjacent fingers. - View Dependent Claims (11)

12. An input sensing module comprising:
-
a flexible base member; a plurality of sensing electrodes disposed on the flexible base member; and a flexible protective member disposed on the flexible base member and protecting the sensing electrodes, the flexible protective member comprising a three-dimensional sensing surface with which a palm of a user is placed in contact, wherein; the sensing electrodes are capacitively coupled to the palm of the user; the flexible base member comprises a first base portion having a first non-flat average curvature and a second base portion having a second non-flat average curvature smaller than the first average curvature; the sensing electrodes comprise first sensing electrodes disposed in the first base portion and second sensing electrodes disposed in the second base portion, the first sensing electrodes have a first pitch, and the second sensing electrodes have a second pitch greater than the first pitch; the first pitch is defined by a sum of a first width of an electrode of the first sensing electrodes and a first distance between the first sensing electrodes adjacent to each other; and the second pitch is defined by a sum of a second width of an electrode of the second sensing electrodes and a second distance between the second sensing electrodes adjacent to each other. - View Dependent Claims (13, 14, 15, 16, 18, 22, 23)
