Towards Context Classification and Reasoning in IoT

November 21st, 2017|Publications|

Internet of Things (IoT) is the future of ubiquitous and personalized intelligent service delivery. It consists of interconnected, addressable and communicating everyday objects. To realize the full potentials of this new generation of ubiquitous systems, IoT's `smart' objects should be supported with intelligent platforms for data acquisition, pre-processing, classification, modeling, reasoning and inference including distribution. However, some current IoT systems lack these capabilities: they provide mainly the functionality for raw sensor data acquisition. In this paper, we propose a framework [...]

Together or Alone: Detecting Group Mobility with Wireless Fingerprints

November 21st, 2017|Publications|

This paper proposes a novel approach for detecting groups of people that walk “together” (group mobility) as well as the people who walk “alone” (individual movements) using wireless signals. We exploit multiple wireless sniffers to pervasively collect human mobility data from people with mobile devices and identify similarities and the group mobility based on the wireless fingerprints. We propose a method which initially converts the wireless packets collected by the sniffers into people’s wireless fingerprints. The method then determines group [...]

Crowd behaviour analytics focuses on behavioural characteristics of groups of people instead of individuals’ activities. This work considers human queuing behaviour which is a specific crowd behaviour of groups. We design a plug-and-play system solution to the queue detection problem based on Wi-Fi/Bluetooth Low Energy (BLE) received signal strength indicators (RSSIs) captured by multiple signal sniffers. The goal of this work is to determine if a device is in the queue based on only RSSIs. The key idea is to [...]

Analysis of Security Standardisation for the Internet of Thing

November 21st, 2017|Publications|

  Recently, Internet of Things (IoT)-related studies actively being conducted in various fields. Like conventional network system, IoT can also be a target for security attacks. With these problems for IoT security being magnified, many researchers are studying and developing countermeasures. Although a lot of companies launch products and services, they do not know how to apply countermeasures to products and services without interoperability problems. In IoT environments, integration is a necessary process between heterogeneous products and services from multiple [...]

Secure IoT Platform for Industrial Control Systems

November 21st, 2017|Publications|

Supervisory control and data acquisition (SCADA) systems, are part of industrial control system (ICS), have been playing crucial roles in real-time industrial automation and controls. Through the evolution of 3rd generation, or networks based system, SCADA systems are connected to almost types of networks such as wired, wireless, and cellular and satellite communication, but security is still a big challenge for SCADA system while communicating within. Internet of things (IoT) is a ubiquitous platform, a new advance enhancement, for efficient [...]

Security Requirement Analysis for the IoT

November 21st, 2017|Publications|

  Due to the rapid growth of network infrastructure and sensor, the age of the IoT (internet of things) that can be implemented into the smart car, smart home, smart building, and smart city is coming. IoT is a very useful ecosystem that provides various services (e.g., amazon echo); however, at the same time, risk can be huge too. Collecting information to help people could lead serious information leakage, and if IoT is combined with critical control system (e.g., train [...]
