Speaker: Prof. Xuemin (Sherman) Shen, Department of Electrical and Computer Engineering

Abstract: It is envisioned 5G Networks will integrate diverse spectrum, deployments, technologies to achieve diverse and enhanced KPIs and support diverse applications and services. In special, 5G networks are expected to support data rates of 10-50 Gbps for low-mobility users, deliver an end-to-end latency of less than 5 milliseconds and over-the-air latency of less than one millisecond, broad coverage area, and efficient use of the spectrum by using MIMO, advanced coding and modulation schemes and new waveform design. The question is how challenge and difficult it is to achieve the expected performance. Can we have alternative and better approach to achieve such performance? In this talk, we introduce Space-Air-Ground Integrated Networks by making use of the advantages of different networks to achieve the performance goal. We also present our developed Space-Air-Ground Integrated Networks simulator for demonstration.

Title: Image Pixelization with Differential Privacy
Speaker: Dr. Liyue Fan, University at Albany, SUNY
Abstract: Ubiquitous surveillance cameras and personal devices have given rise to the vast generation of image data. While sharing the image data can benefit various applications, including intelligent transportation systems and social science research, those images may capture sensitive individual information, such as license plates, identities, etc. Existing image privacy preservation techniques adopt deterministic obfuscation, e.g., pixelization, which can lead to re-identication with well-trained neural networks. In this talk, I will describe sharing pixelized images with rigorous privacy guarantees. We extend the standard differential privacy notion to image data, which protects individuals, objects, or their features. Empirical evaluation with real-world datasets demonstrates the utility and efficiency of our method; despite its simplicity, our method is shown to effectively reduce the success rate of re-identication attacks.
