Abstract
Techniques for watermarking structured data, such as map data are addressed. These techniques advantageously allow the detection of an unauthorized copy of the original data and to track the source of the unauthorized copy based upon a variety of opportunities to access the unauthorized copy. For example, in an Internet context, an unauthorized copy of a map may be provided to online customers so that they can make queries such as the distance between two driving destinations. Having such access, copies can be detected and traced to the original purchaser of the map.
