User authentication

A method for providing security at a door entry location, the method comprising:

• receiving, by a processor unit of a door entry system, a plurality of user inputs via a pressure-sensitive input interface, the pressure-sensitive input interface being a plurality of pressure-sensitive buttons arranged on a numerical keypad of the door entry system;
• determining, by the processor unit, a pressure applied to the pressure-sensitive buttons by a user when attempting to unlock the door entry system;
• and
• distinguishing, by the processor unit, real user inputs that represent a component part of an authentication code or pattern from fake user inputs that do not represent a component part of the authentication code or pattern, based on the pressure applied to the pressure-sensitive input interface.

A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for providing security at a door entry location, the method comprising:

• receiving, by a processor unit of a door entry system, a plurality of user inputs via a pressure-sensitive input interface, the pressure-sensitive input interface being a plurality of pressure-sensitive buttons arranged on a numerical keypad of the door entry system;
• determining, by the processor, a pressure applied to the pressure-sensitive buttons by a user when attempting to unlock the door entry system;
• and
• distinguishing, by the processor, real user inputs that represent a component part of an authentication code or pattern from fake user inputs that do not represent a component part of the authentication code or pattern, based on the pressure applied to the pressure-sensitive input interface.
