Abstract
In today's digital world securing dierent forms of content is very important in terms of protecting copyright
and verifying authenticity. Many techniques have been developed to protect audio, video, digital documents,
images, and programs (executable code). One example is watermarking of digital audio and images. We believe
that a similar type of protection for printed documents is very important. The goals of our work are to securely
print and trace documents on low cost consumer printers such as inkjet and electrophotographic (laser) printers.
We will accomplish this through the use of intrinsic and extrinsic features obtained from modelling the printing
process. In this paper we describe the use of image texture analysis to identify the printer used to print a
document. In particular we will describe a set of features that can be used to provide forensic information about
a document. We will demonstrate our methods using 10 EP printers.
