Abstract

The present invention can be a method, system, and computer program product. One embodiment of the present invention provides a computer-implemented method for identifying an artificial object. The method includes receiving capacitance data which is obtained by measuring with at least one electrodes in a sensor at least one predefined surfaces of the artificial object placed against the sensor; converting each of the obtained capacitance data into an evaluation level in an evaluation system having more than two evaluation levels, to obtain a capacitance distribution on the surface of the artificial object; determining whether the obtained capacitance distribution matches a pre-registered capacitance distribution or one of pre-registered capacitance distributions; and if the determination result is positive, concluding the artificial object is identified. The method can further include identifying or performing an authentication of a user associated with the artificial object when artificial object is identified.
