  • Abstract
    A scheme is developed to help prevent the use of new generations of copying equipment to forge products. Computer images of three-dimensional reflective particle labels are encoded using the Walsh-Hadamard transform. An optimal quantizer and the encodings are then used to authenticate the labels
