Abstract
Systems and methods applicable, for instance, to the generation and usage of authentication images. In one aspect, unauthorized attempts to duplicate authentication images can be thwarted. In another aspect, there can be provision for authorized authentication image generation using low-resolution print devices.
Claims23
An authentication image, comprising:
- one or more latent images, wherein the latent images indicate authenticity;
- and
- one or more background images, wherein the background images work in conjunction with the latent images to inhibit unauthorized duplication of the authentication image,
- wherein generation of the authentication image utilizes knowledge of idiosyncrasies of one or more of low-resolution print devices or home/office equipment such that the authentication image scans as valid;
- and
- wherein authorized software uses knowledge regarding the background images and knowledge regarding the latent images to yield one or more of the latent images from the authentication image.
3 more elements
A computer-implemented method, comprising:
- generating, by a computing system, an uncompensated print file for an authentication image, wherein printing of the uncompensated print file by a low-resolution print device yields a print result not matching the uncompensated print file;
- and
- generating, by the computing system, from the uncompensated print file, a compensated print file for the authentication image, wherein the generation of the compensated print file utilizes known low-resolution print device idiosyncrasies, and wherein printing of the compensated print file by the low-resolution print device yields an authentication image print result that scans as valid.
