Abstract
A method for detecting authorized 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; eroding the image data; counting the pixels which remain at or above the predetermined brightness level after erosion to determine a second score; calculating a ratio of the second score to the first score; and producing a first authentication signal if the ratio meets a first predetermined criteria.
