Abstract
An embedded data code comprises periodic tiles having occlusions. In one embodiment, each tile is comprised of glyphs encoding a first code system. The occlusions are comprised of information, such as glyphs encoding a second code system, graphics, or text. The occlusions may occur periodically in each tile. A reading device may be used to capture an image of a portion of the substrate that includes a tile. A processor then analyzes the image to determine the tile code pattern and decode the tiled code.
