Venue: Athena Auditorium, MYRA School of Business

 

Talk Summary:

Context. A word that is hard to define if we don’t know the “context” to which we are referring. Systems and interactions with such systems are more meaningful, useful, usable and efficient if context is considered as a core element in the system design. So does life in general.
In this talk, Raghav will discuss the importance of context in modern day computing, especially in the Internet of Things. The talk will also cover the use of contextual information in various application domains such as mobile device security, user authentication, personal safety, remote healthcare, and visualization in coordinated and multiple view environments. Raghav will also share his lessons in iterative evolution of research projects.

 

About the Speaker:

Dr. Raghav V. Sampangi is an Instructor at the Faculty of Computer Science, and a Faculty Associate at the Centre for Learning and Teaching, at Dalhousie University, Canada. His research interests include investigating issues with security, usability and interactions for context-aware devices in the Internet of Things (IoT), and designing mechanisms to overcome them.
He holds a Ph.D. in Computer Science from Dalhousie University, Halifax, Canada, where he worked on a context-dependent adaptive mechanism for security; particularly, key generation and authentication. He also holds a Bachelor’s degree (B.E) in Electronics and Communication Engineering from Visvesvaraya Technological University, Belgaum, India, and a Master’s degree (M.Tech) in Information Systems and Management from the University of Mysore, Mysore, India. He is a proponent of lifelong learning and considers every interaction the source of a life lesson.

Dr. Raghav V. Sampangi delivered a lecture on “Context-Aware Research Adventures” at MYRA School of Business on December 29, 2016.

Context is a term that is defined in several different ways in different contexts (pun intended). Recognizing this aspect, Dr. Sampangi has focused his efforts on developing a definition for the term context that is adaptive and usable in several technology solutions. In this talk, he discussed the main aspects of a context-aware system, namely: sensing, understanding the context and adapting the system behaviour. He also identified the fact that several context-aware systems that are currently available in the market focus on one or two key aspects that determine the context of use, and not all. This, he said, was the motivating factor for him to develop a usable and adaptive definition for context.

Dr. Sampangi also discussed the impact of sensors and unique identification technology on everyday living, especially healthcare. However, making these technologies available generally also requires them to be affordable. Affordability often implies that there will be trade-offs in some aspects of the system, and typically, security is reduced (or not offered at all) to make way for functionality. Motivated by this aspect, Dr. Sampangi has also been focusing his efforts on developing “lightweight” solutions for security in sensor and unique identification devices that form a core part the Internet of Things. In that context, he discussed three algorithms that he has designed during over the past few years to secure such devices.

He stressed on the fact that developing modular solutions to security and privacy also ensures that it is easy to swap modules when technology evolves. This, he said, was a way to be ready for an ever-changing technology domain.

Dr. Sampangi also shared some general life-lessons throughout his talk, as a way to recognize that it is important for us to learn lessons from all interactions in our lives, and that we should not be demotivated by things we experience. There is always a lesson to be learned, and this prepares us to be better prepared for the future.
