Abstract
A method, service, and product for hiding a watermark existing in a digital media within a software application, comprising creating a set pattern of pixels represented by coordinates which represent a red, a green, a blue, and an alpha level of color, where the set pattern of pixels covers a set of original pixels within the digital media. The method including determining whether the transparency level of color should be removed from the set pattern of pixels based on a known pixel transparency removal parameter; and modifying the set pattern of pixels to remove the transparency level of color coordinates, wherein an original pixel color can be seen because the set pattern of pixels are made transparent; or not modifying the set of pixels to remove the transparency level of color coordinates, wherein the original pixel color cannot be seen because the set of original pixels is made transparent.
