  • Patent number: 6414757
    Abstract: A system and method for secured image creation. A bitmap image is processed to separate color or greyscale planes, or is used as a greyscale, single plane image. The plane(s) are each converted into microtype character layers with each layer arranged at a different angle relative to another layer. The microtype character width is modulated in width based or color or greyscale values and, if multiply colored, the layers are superimposed to form a processed image with anti-counterfeit, anti-scan and anti-copy properties.
