In this paper we present a feasibility study of printed document forensics based on steganographic anti-counterfeiting markings using portable devices. We propose two system architectures and analyze their pros and contres for mass usage. Furthermore, we perform an analysis of the probability of error that can be attained in the system based on steganographic anti-counterfeiting markings and explicit the conditions to reach reliable performance.
