Digital anti-counterfeiting software method and apparatus
First Claim
1. An automated method for digitally encoding at least one digital image into a source image so that the at least one digital image is not discernible within the source image without application of a reader having a frequency pattern, the method comprising:
- obtaining the at least one digital image having a first pattern of line elements, the first pattern of line elements corresponding to the selected frequency pattern of the reader;
obtaining the source image having a second pattern of line elements;
applying an encoding algorithm to incorporate the at least one digital image into the source image; and
generating a revised source image comprising the first pattern of line elements and the second pattern of line elements,wherein the revised source image substantially replicates the source image when viewed without the reader, andwherein the first pattern of line elements are configured in the revised source image to be hidden until viewed with the reader having the selected frequency pattern.

Abstract
This invention relates generally to a method and apparatus, as implemented by a software program on a computer system, for digitally producing counterfeit-deterring scrambled or encoded indicia images. This method and system are capable of combining a source image with a latent image so the scrambled latent image is visible only when viewed through a special decoder lens. The digital processing allows different latent images to be encoded according to different parameters. Additionally, latent images might be encoded into single component colors of an original visible image, at various angles from each other.

7. A non-transitory computer storage medium having software code stored thereon, the software code being configured to cause a computer to execute a method for digitally encoding at least one digital image into a source image so that the at least one digital image is not discernible within the source image without application of a reader having a selected frequency pattern, the method comprising:
-
obtaining the at least one digital image having a first pattern of line elements, the first pattern of line elements corresponding to the selected frequency pattern of the reader; obtaining the source image having a second pattern of line elements; applying an encoding algorithm to incorporate the at least one digital image into the source image; and generating a revised source image comprising the first pattern of line elements and the second pattern of line elements, wherein the revised source image substantially replicates the source image when viewed without the reader, and wherein the first pattern of line elements are configured in the revised source image to be hidden until viewed with the reader having the selected frequency pattern. - View Dependent Claims (8, 9, 10, 16, 17, 18, 19, 20)
