Abstract

Artifact-metrics authentication is a method to authenticate artifacts that have measurable intrinsic characteristics like microscopic random patterns produced in the manufacturing process. In this study, we use a single-walled carbon nanotube (SWCNT) composite paper that is a composite material made from the mixture of the SWCNTs and the pulp (paper materials), as the material of a new artifact-metrics authentication. Advantages of using SWCNT-composite papers, for example, are easy to handle and to make, and impossible to replicate the patterns. As authentication methods, we focus on the use of Raman spectroscopic characteristics of the SWCNTs, and use features of the distinctive SWCNT patterns in each paper, for authentication “keys.” The estimated result of error rate = 10-5 or less was obtained from an experiment that used combination data obtained from specific Raman peaks of the SWCNTs. Our SWCNT-composite papers also have the other usable properties that can be used for authentication keys, thus we are able to improve authentication accuracy more using those keys.
