USENIX Security ’21 – Kalεido: Real-Time Privacy Control for Eye-Tracking Systems
Kalεido is a real-time privacy control framework for eye-tracking systems presented at USENIX Security ’21. It is designed to mitigate privacy concerns by allowing users to dynamically control the visual information captured by eye-trackers.
Eye-tracking systems are widely used in various applications, including gaming, virtual reality, and human-computer interaction. However, these systems raise privacy concerns as they capture users’ eye movements and can potentially reveal sensitive information.
Kalεido addresses this issue by providing users with real-time control over the visibility of their eye movements. It offers three different privacy levels: Full Disclosure, Blurring, and Concealing. Full Disclosure shares unmodified eye-tracking data, while Blurring and Concealing distort or completely obfuscate the eye movements, respectively.
The framework utilizes a combination of wearable devices and computer vision algorithms to achieve real-time privacy control. Users wear an infrared-transparent eyepatch, which enables eye-tracking while protecting privacy. Computer vision algorithms analyze the captured video feed and apply the chosen privacy level before transmitting the gaze data.
The effectiveness of Kalεido was assessed through a user study with 30 participants. The results showed that users found the privacy controls intuitive and easy to use. Participants expressed a high level of trust in the system’s ability to protect their privacy.
In conclusion, Kalεido is a novel real-time privacy control framework for eye-tracking systems. It addresses privacy concerns by offering users granular control over the visibility of their eye movements. The framework’s effectiveness was demonstrated through a user study, where participants expressed satisfaction and trust in the system’s privacy protection capabilities.
