Electronic book content protection

摘要

A system and method are disclosed for protecting an electronic book from unauthorized access. HTML for the book is shredded by dividing it into portions, and a selection scheme is used to intersperse decoy data among the portions. Dynamically generated cascading style sheets are used to define a pattern for decoy and content data such that a browser on a client device correctly processes the HTML but an unauthorized program such as a web scraper cannot correctly process the HTML.
