Data Hiding Capacity and Embedding Techniques for Printed Text Documents
Abstract:In previous publications we have demonstrated the use of laser intensity modulation to embed information in halftone and text documents. In those experiments we were able to embed and correctly decode 33 bits in a 12 point page of printed text. In this paper we will present our current work on developing a channel model for a text document. This model will allow us to define capacity bounds for the channel and to better understand the modulation and detection techniques that can be used to reach that capacity.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
