Human-centred Privacy and Security

Managing security and privacy in our hyper-connected world is increasingly difficult. Our research aims to help people manage their privacy and security online. We use both HCI and AI methods for this. We apply HCI methods to study users’ perceptions, mental models, and preferences regarding security and privacy. We also apply AI models and technologies to support users when managing their security and privacy online, for instance, by learning what their privacy preferences are and automatically applying them online.

We have applied our human-centred privacy and security research across different domains and systems, from the web, to social media, to the cloud to the smart home. We have also focused, using a similar approach, on the problem of Multiuser Privacy.
