Trust TEE?: Exploring the Impact of Trusted Execution Environments on Smart Home Privacy Norms

IoT devices like smart cameras and speakers provide convenience but can collect sensitive information within private spaces. While research has investigated user perception of comfort with flows originating from these types devices, little focus been given to the role sensing hardware in influencing sentiments. Given proliferation trusted execution environments (TEEs) across commodity- server-class we surveyed 1049 American adults using Contextual Integrity framework understand how inclusion cloud-based TEEs ecosystems may influence data collection use. We find that significantly increase flows. These increases are more pronounced for manufactured by smaller companies show bridge previously-documented gulfs trust between small large companies. Sentiments around consent, bystander data, indefinite retention unaffected presence TEEs, indicating centrality norms.
