Abstract: A system for verifying product authenticity. A verification system may include: coded microstructures contained within a product. In particular implementations, such as pharmaceuticals, the microstructures are edible and, in some cases, even digestible. Glyph coding may be included to enhance the readability of the microstructures that may have been damaged during manufacture. Microstructures may be incorporated into the product so that they are not visible from the outside of the product to increase the difficulty of counterfeiting the product.
