1. A method for making an authenticating system for an object, the method comprising: selecting an image; adding a watermark in a predetermined area of the image, the predetermined area being a portion of the image; adding an other watermark in an other area of the image such that the other watermark overlaps with the watermark in the image; establishing the image having the watermarks therein on the object or on a package for the object using opaque ink, whereby the image, the watermark, and the other watermark are printed with the opaque ink; and associating at least one of the watermarks with the object to render object-specific authenticating data.
