Zusammenfassung:	Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for applying a ghost image to an identification document that include the actions of obtaining a first image of an object. Identifying a first portion of the first image that corresponds with the object and a second portion of the first image that does not correspond with the object. Generating a second image by converting the first image to a negative image, and removing the second portion of the first image that does not correspond to the object. Generating a halftone image from the second image. Causing optically variable media to be applied to the identification document based on the halftone image. The optically variable media has a first appearance when viewed from in reflected light at a first angle and a second, different appearance when viewed in reflected light at a second, different angle.
