Abstract
A method for authenticating security markers includes capturing an image of a region of interest on a product with a camera; storing image data in a two-dimensional array on a microprocessor; counting a number of pixels at or above a predetermined brightness level in the image data with the microprocessor to determine a first score; establishing an area within the image; counting a number of pixels within the area to determine a second score; calculating a ratio of the second score to the first score; and if the ratio is above a predetermined threshold the security marker is authenticated.
