The ubiquity of technologies such as on-line data repositories, biometric identification systems, smart electricity meters, etc., has created new challenges in information security and privacy. Information theory provides fundamental limits that can guide the development of methods for addressing these challenges. This talk will first describe a fundamental information theoretic framework for examining, in a general setting, the tradeoff between the privacy of data and its measurable benefits. This framework will then be used to investigate this tradeoff in several problems arising in the applications noted above.

Extraordinary advances in sequencing technology in the past decade have revolutionized biology and medicine. Many high-throughput sequencing based assays have been designed to make various biological measurements of interest. A key computational problem is that of assembly: how to reconstruct from the many millions of short reads the underlying biological sequence of interest, be it a DNA sequence or a set of RNA transcripts? Traditionally, assembler design is viewed mainly as a software engineering project, where time and memory requirements are primary concerns while the assembly algorithms themselves are designed based on heuristic considerations with no optimality guarantee. In this talk, we outline an alternative approach to assembly design based on information theoretic principles. Starting with the question of when there is enough information in the reads to reconstruct, we design near-optimal assembly algorithms that can reconstruct with minimal amount of read information. We implement the algorithms in multi-core software and test them on real data to compare with state-of-the-art software in the field.

The rapid advances in networking and computing technologies have brought the first big wave of Internet revolution since the 90’s. Combined with this, the latest mobile networking, smartphone and cloud computing technologies led to the second big wave of mobile big bang. Internet of Things (IoT) is the latest big wave impacting the way we live, travel, work and enjoy. Apple, Google, Amazon, Facebook and many other global Internet players have emerged and have been introducing numerous innovative services and open ecosystems. These advances and challenges have greatly affected the telecommunications industry over the past decade. This talk will explain the challenges faced by telcos around the world and how they have been changing, including KT. The latest information and communications technologies (such as SDN/NFV, LTE/LTE-A/5G) will be described. Emerging services such as Smart IPTV, Digital Goods, Clouds, ICT Convergence (such as Smart Home, Smart Energy, e-Healthcare), and Internet of Things will be described along with their R&D challenges.

5G, Vision and Future Works 

Driving largely by mobile internet and internet of things, 5G and future wireless networks are facing the challenge of higher user experienced data rates, lower latency, higher traffic volume density and higher connection density. The traditional cellular technology has been difficult to meet the requirements. Unlike the previous four generation of cellular technology, 5G and the future networks will be high densification and highly integrative: tying any new air interface and spectrum together with current cellular networks and WiFi to provide higher capacity. To support this, the integrative wireless network architecture and new technology should be studied to provide energy-efficient, spatial densification, spectral aggregation, and backhaul densification network. This speech will discuss all of these topics, identify key challenges and candidate technologies for future research, and introduce the current activities of 5G within China.
