Copyright protection and distribution system for scanned books/comics

The book scanning agency scans paper books, and converts them to e-book format. However those e-books are vulnerable to illegal copy, because they don't have any copyright protection technologies. In addition to the e-books, illegally scanned books and comics are distributed at commercial on-line storage site without any regulations. To resolve such problems, in this paper, we proposed a system of identification and copy protection for scanned books and comics.
