Design of automatic paper identification system with QR code for digital forensics

Abstract

As the printing technology is developing, the use of digital documents which is printed with a variety of printing papers is increasing. And the increase in criminal forgery of digital documents has been the cause of many social problems. As a result, the development of digital forensic techniques to collect and analyze the evidence of the crime of forgery of digital documents is increasingly important. In this paper, we propose an automatic paper identification technique with QR code that is formed based on the extracted features from each paper's microscope image. © Springer-Verlag Berlin Heidelberg 2014.
