Printer Forensics Using SVM Techniques

Abstract

In today's digital world securing different forms of content is very important in terms of protecting copyright and verifying authenticity. We have previously described the use of image texture analysis to identify the printer used to print a document. In particular we described a set of features that can be used to provide forensic information describing a document. In this paper we will introduce a printer identification process that uses a support vector machine classifier. We will also examine the effect of font size, font type, paper type, and “printer age”.
