Towards private proximity services, we realized a set of proximity services at different spatial resolutions. For small-scale (∼ 0.5 m) securing remote access to smart homes and for mid-scale (10-20 m) to manage nearby Internet of Things (IoT) devices and offer fine-grained service discovery in indoor environments. Regarding large-scale services (100 m), we implemented a device grouping via similarity of light patterns, ambient sound, Wi-Fi signals, and ultrasound communication which is

To improve user's privacy from a system point of view, we analyzed different security mechanisms in the domain of device-to-device (D2D) communication such as access control, location privacy. Based on visible light communication (VLC), we are implemented and tested a system for private indoor service discovery and distance-bounding authorization. Furthermore, we examined the feasibility of homomorphic encryption for time-series data like visible light patterns.
