Claim 13:
14. A method of devising an authentication tool which is to reside on a mobile apparatus as a set of computer executable instructions in the form of a trained neural network, wherein the mobile apparatus is to operate as an authentication apparatus to determine whether a captured image is a primary image or a non-primary image of a data-coded image pattern of an authentic information bearing device upon execution of the instructions of the authentication tool, and wherein the trained neural network comprises a number of channels and each channel has a plurality of feature data; wherein the method comprises:
feeding a computer-based neural network with a plurality of training files, wherein each training file is a data file of a training image comprising a plurality of image-defining elements, wherein the training images comprises a plurality of primary images of the data-coded image pattern and a plurality of non-primary images of the data-coded image pattern, and wherein the data-coded image pattern comprises a set of spatially distributed pattern defining elements which correlates to a coded data by a domain transformation function and has a characteristic signal strength relating to magnitude of the coded data; and
training the neural network to differentiate between a primary image and a non-primary image with reference to the characteristic signal strengths of the primary images and the non-primary images to obtain the feature data to form the trained neural network.
