A tile-based arrangement is employed to effect watermarking of plural-bit auxiliary data into still or moving digital images. In a particular embodiment, the plural-bit auxiliary data is represented as a rectangular block of overlay data. This block is repetitively tiled, both vertically and horizontally, across the image, and combined with the image data to effect the encoding.
