Physical I.D.: Development of artificial skin that is physically difficult to duplicate

Abstract

In recent years, digital transformation has attracted attention. In such a situation, since the exchange of data between manufacturing equipment and control equipment increases with the adoption of IoT, there is a possibility of security problems occurred by duplication of manufacturing robots in factories. Therefore, the management method of the robot is not based on data like QR code, but is studied by attaching a unique physical pattern. In this study, we focused on the fact that a tuning pattern can be obtained by using two soft materials with different curing times, and produced a Physically Unclonable Artificial Skin (PUAS) with various surface patterns by changing the mixing ratio. As a result, the characteristics of the patterns by mixing ratio were found.
