There are several interesting topics here. The use of Google Glass to analyze passcodes doesn't surprise me much - It does give some yet another reason to be suspicious of people wearing them. Doing so anywhere near an ATM has to be marked up as a bad idea anyway. Random analysis of RF signals seems like something to do only if you have way too much time on your hands, but I know people that would do it. I have to admit being intrigued by the use of acoustic anomalies to identify fraudsters - Unless, of course, 'acoustic anomalies' is simply a fancy way of describing things that they are saying that just don't make sense... :-)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
