abstract

In today'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 has the capability to embed 14 bits into characters that have a left vertical edge. For a typical 12 point document this translates to approximately 12000 bits per page.
