Family Dynamics-based Access Control for IoT

Family Dynamics-based Access Control for the Internet of Things

Today, children are increasingly connected to the Internet and consume content and services through various means. It has been a challenge for less tech-savvy parents to protect children from harmful content and services. Internet of Things (IoT) has made the situation much worse as IoT devices allow children to connect to the Internet in novel ways (e.g., connected refrigerators, TVs, and so on). In this work, we propose to utilise family dynamics to provide a more natural, and intuitive access control mechanism to protect children from harmful content and services. In our proposed approach, access control dynamically adapts based on the physical distance between family members. For example, a particular type of content can only be consumed, through TV, by children if the parents are in the same room (or hearing distance). This approach allows parents to assess a given content by themselves. This is a contrasting view to AI-based decision making where AI decide on behalf of the parents. We believe that parents are the best person to make the decision, given that they get the right opportunity. Our access control mechanism aims to guarantee that opportunity (i.e., block certain content, services, and devices when the parents are not in the vicinity). We developed a prototype using OpenHAB and several smart home devices to demonstrate the proposed approach. We also conducted a focus group to identify how family dynamics can be further used to support better security and safety for children. We believe that our approach also facilitates the creation of better relationships between family members.
