Systems and methods for authentication of a consumer product are provided herein. An embodiment of a method for authentication of a consumer product includes providing the consumer product, optionally with packaging material associated therewith. Filtered light from an intrinsic portion of the consumer product or packaging material associated therewith is detected using a photodetector of a portable computing device to produce at least one single-color image data set representative of the intrinsic portion for at least one color. The at least one single-color image data set is compared with a stored data set that is representative of authentic information for the intrinsic portion using a microprocessor of the portable computing device, with the comparison conducted independent of and separate from any analysis of non-color data obtained from preconfigured security features. An indication of authenticity of the consumer product is provided based upon the comparison.

A security article is a substrate having a diffractive grating thereon, coated with a windowed high index layer and a color shifting coating visible through the window. The color shifting coating is disposed on the high index layer or on the opposite side of the substrate. Alternatively, a thin film color shifting structure conforming the diffractive grating is disposed between the grating and the windowed high index layer, also conforming to the shape of the diffractive grating. Alternatively, an ink with low density of color shifting pigments is applied over the high index layer conforming to the shape of the diffractive grating. The resulting color shifting image provides a reference to a holographic image.
