This paper presents a 3-D hand gesture capture technique using the 2D camera and Wi-Fi connection signals of a smartphone. The motion detection principle of this technique involves combining the algorithm of pixel-based computer vision and the extraction of Doppler shift from the reflected Wi-Fi signals. Moreover, a joint displacement calibration procedure is proposed to transform the camera pixel...
Differential privacy (DP) is a framework to quantify to what extent individual privacy in a statistical database is preserved while releasing useful aggregate information about the database. In this work, we aim an exploratory study to understand questions related to the optimality of noise generation mechanisms (NGMs) in differential privacy by taking into consideration the (i) query sensitivity,...
