Smart Home Beyond the Home: A Case for Community-Based Access Control

As smart devices are becoming commonplace in homes, we need to explore the needs of not just the residents of the home, but also of secondary stakeholders who may be granted access to these devices from outside of the home. We conducted a mixed methods study, which included a survey of 163 smart home device owners and a follow-up interview with 13 individuals who currently share their smart home devices with others outside of their home. Nearly half (47.8%) of our survey participants shared at least one smart home device with someone that did not live with them. Individuals sought greater safety and security by providing remote access to trusted family members or friends. By understanding users' perspectives about privacy and trust in relation to sharing smart home devices beyond the home, we build a case for community-based access control of smart home devices in the Internet of Things.

随着智能设备在家庭中日益普及，我们不仅需要探究家庭居住者的需求，还需考虑可能从家庭外部被授予访问这些设备权限的次要利益相关者的需求。我们进行了一项混合方法研究，其中包括对163名智能家居设备所有者的调查，以及对13名目前与家庭外部人员共享智能家居设备的个人进行的后续访谈。在我们的调查参与者中，近一半（47.8%）至少与不住在一起的人共享了一种智能家居设备。个人通过向信任的家庭成员或朋友提供远程访问权限来寻求更高的安全性。通过了解用户对于在家庭之外共享智能家居设备相关的隐私和信任的看法，我们为物联网中智能家居设备基于社区的访问控制提供了依据。
