Texture block coding
A method of watermarking that hides data within the continuous random texture patterns of an image. The technique is implemented by copying a region from a random texture pattern found in a picture to an area that has similar texture, resulting in a pair of identically textured regions in the picture.

A watermarking attack that is particularly useful for images that are distributed over the Internet. It relies on a web browsers ability to assemble mutiple images so they appear to be one image. A watermarked image can be broken into pieces but displayed as a single image by the browser. Any program trying to detect the watermark will look at each individual piece, and if they are small enough, will not be able to detect the watermark.
