Authentication method and system
First Claim
1. A method comprising the steps of:
- providing, by an electronic device and for display within a keypad zone of a screen associated with an electronic device, an operable keypad;
generating, by a remote server, a plurality of images scrambled keypads;
removing, by the remote server and from the plurality of images of scrambled keypads, any image that represents a scrambled keypad having at least one key in a same position as a respective key of the operable keypad to provide a remaining plurality of images;
selecting, by the remote server and from the remaining plurality of images, an image of a scrambled keypad;
sending, from the remote server and for delivery to the electronic device the image of the scrambled keypad;
outputting, by the electronic device and for display at least partially within the keypad zone, at least a portion of the image of the scrambled keypad; and
receiving, at the electronic device, by operation of at least one key of the operable keypad via the image of the scrambled keypad, an identifier.

Abstract
The invention provides a computer-implemented authentication method comprising the step of enabling a user to input an identifier (e.g. a PIN) into an electronic device having a screen and a keypad operable within a keypad zone of the screen; by operating at least one key of the keypad via an image of at least part of a scrambled keypad which is displayed at least partially within the keypad zone. The user'"'"'s operation of the keypad key via the image generates an encoded version of the user'"'"'s intended input. In one sense the invention can be perceived as superimposing a non-functional image of a scrambled keyboard over an underlying, functional keypad. The image may be any type of electronic image, and may include a video image. The invention is particularly suited for use with, but not limited to, mobile phones, tablet computer, PCs etc. It can be implemented in any system wherein a user'"'"'s identity must be verified before access is granted to a controlled resource.
