Abstract
A variable data addition method and system are disclosed herein. The method includes generating an original image, and defining at least one sub-section of the original image to transform individually. A reversible transformation is applied to the defined at least one sub-section, thereby altering the original image to form an altered image that is non-readable until an inverse of the reversible transformation is applied to the altered image.
