Abstract (in Japanese) (See Japanese page) 
(in English) This study proposes and evaluates Fonty, a copy protection technology for text content. First, Fonty encrypts text content by applying certain substitution rules that exchange characters. Next, Fonty edits the mapping between characters and glyph shapes in the web font according to the above substitution rule. The decrypted text content is automatically displayed in the user's browser when rendered using web fonts. The proposed method keeps the text encrypted even within the user's browser, and the user cannot copy the text described in the HTML. We have found through user studies that the text protected by the proposed method is highly copy resistant compared to existing copy protection.
