Will security concerns prevent widespread adoption of wearables and IoT devices?

This week's Question: In the paper " Friend or Foe?: Your Wearable Devices Reveal Your Personal PIN  " scientists from Binghamton University and the Stevens Institute of Technology combined data from embedded sensors in wearable technologies, such as smartwatches and fitness trackers, along with a computer algorithm to crack private PINs and passwords. By using data from “accelerometers, gyroscopes, and magnetometers inside the wearable technologies regardless of a hand’s pose,” the researchers could record a hand’s fine-grained movements. The researchers then used a “Backward PIN-sequence Inference Algorithm” to crack the codes.
