DataBytes: An NCDS Lunchtime Webinar Series

DataBytes is an NCDS-sponsored lunchtime webinar series that gives our members and the larger data community the chance to discuss the most pressing and interesting issues in data science. Webinars are generally held on the first Wednesday of every month, excluding July. All webinars are easily accessible from the NCDS homepage and from this page. Talks generally last 30 to 45 minutes, followed by Q and A, and conclude no later than 1 p.m. Questions will be taken via chat. Audience members are encouraged to call in using their computer rather than using the call-in number.
If asked for a password, please use databytes. 

If you are interested in presenting during a DataBytes webinar, please email subers@renci.org.

Title: Privacy Analytics of Homegrown IoT Data

Speaker: Shahriar Nirjon, assistant professor in the Department of Computer Science at UNC-Chapel Hill

About the Talk: 

The growing network of interconnected devices known as the Internet of Things (IoT) promises to make humans more productive, efficient, and healthy using sensors that monitor everything from the number of steps we take each day to the temperature of our homes. But a major concern about the IoT is its lack of security measures, which creates anxiety about exposing our most personal data.

The problem becomes even more complicated when households deploy multiple smart devices—all capable of being hacked and giving up sensitive data. There is a recent trend in the IoT world that many third-party, commercial IoT devices are now becoming voice enabled by using the APIs offered by the voice-controlled home-hub devices like Echo or Google Home. Because these home-hubs enable actuation and control of real-world entities, a potential danger is that they can be activated by false commands (e.g., sounds from a TV) and/or unauthorized commands (e.g., an outsider commands someone’s home hub to control his home appliances, places a large purchase on his Amazon account, or calls an Uber driver). A careful scrutiny of voice commands is therefore a necessity to ensure safety and security.

In this webinar, Nirjon discusses his research on the ‘overhearing’ problem of acoustic sensing devices and development of a system that mitigates personal or contextual information leakage due to the presence of unwanted sound sources in the acoustic environment.

About the Speaker:

Shahriar Nirjon is an assistant professor in the Department of Computer Science at the University of North Carolina at Chapel Hill. Shahriar is interested in building practical cyber-physical systems that involve embedded sensors and mobile devices, mobility and connectivity, and mobile data analytics. Research challenges that he deals with include practical issues in physical world sensing, user-contexts and mobility, real-time issues, and resource constraints of the embedded platform. His work has applications in the area of remote health and wellness monitoring, and mobile health.

Shahriar received his Ph.D. from the University of Virginia, Charlottesville in 2014. Shahriar has won a number of awards, including two Best Paper Awards, at the Mobile Systems, Applications and Services (MOBISYS 2014), and the Real-Time and Embedded Technology and Applications Symposium (RTAS 2012). Shahriar has worked as a Research Scientist in the Networking and Mobility Lab at the Hewlett-Packard Labs in Palo Alto, CA (2014 – 2015), and as a Research Intern at Microsoft Research, Redmond, WA (Summer 2013) and at Deutsche Telekom Lab, Los Altos, CA (Summer 2010). Several of his work have been highlighted in the electronic and print media, including – the Economist, the New Scientist, and the BBC.
