Abstract

In todayâ€™s digital world securing different forms of content is very important in terms of protecting copyright and verifying authenticity. One example is watermarking of digital audio and images. We believe that a marking scheme analogous to digital watermarking but for documents is very important. In this paper we describe the use of laser amplitude modulation in electrophotographic printers to embed information in a text document. In particular we describe an embedding and detection process which allows the embedding of between 2 and 8 bits in a single line of text. For a typical 12 point document this translates to between 100 and 400 bits per page. We also perform an operational analysis to compare two decoding methods using different embedding densities.
