Abstract
A system for distributing digital content over a computer network (e.g., the Internet) uses certificates to establish a trust relationship between a content provider and a display device. The certificates identify the display device and the content provider as well as unique characteristics of the distribution. For example, the content provider may be a book publisher and the display device may be a printer/binder.
