"Make the Voodoo Box Go Bleep Bloop:" Exploring End Users' Understanding and Information Needs Regarding Microchips

Julian Speith, Steffen Becker, Timo Speith, Markus Weber, Yixin Zou, Asia Biega, Christof Paar

TL;DR

Microchips underpin modern electronics yet remain opaque to users, raising security and accountability concerns in light of global supply chains. The authors conduct a vignette-based online survey with 250 US participants to assess end users' understanding, desired desiderata, and information needs, finding that while basic knowledge is common, societal and security implications are underappreciated and information needs depend on context and user affinity for technology. The study shows end users highly value cyber security and trustworthiness, prefer information about microchip functionality, approvals, and system interactions over manufacturing details, and exhibit greater information needs in more critical settings. These insights motivate a path toward microchip transparency, including building mental models, designing user-centered information disclosures (e.g., microchip labels), and involving end users in regulatory discussions to better align policy with user information needs and trust requirements.

Abstract

Microchips are fundamental components of modern electronic devices, yet they remain opaque to the users who rely on them daily. This opacity, compounded by the complexity of global supply chains and the concealment of proprietary information, raises significant security, trust, and accountability issues. We investigate end users' understanding of microchips, exploring their perceptions of the societal implications and information needs regarding these essential technologies. Through an online survey with 250 participants, we found that while our participants were aware of some microchip applications, they lacked awareness of the broader security, societal, and economic implications. While our participants unanimously desired more information on microchips, their specific information needs were shaped by various factors such as the microchip's application environment and one's affinity for technology interaction. Our findings underscore the necessity for improving end users' awareness and understanding of microchips, and we provide possible directions to pursue this end.
