Video description: The Internet of Things (IoT) is a network of devices that collect and exchange data, where the physical world and the internet converge. The promise of IoT is efficiency and convenience — devices like Amazon’s Alexa that serve as a personal assistant, thermostats that adjust automatically based on use patterns, appliances turned on and off remotely with smartphones and wrist watches that measure our physical activity. The potential cost is privacy, security and freedom. Who owns the information that’s collected by these gadgets? How can private companies use this information? Perhaps more problematic, are we simply creating new portals for conflict, such as when hackers used webcams to shut down Twitter? As the lines between state and non-state actors blur, critical questions remain: Whom do we trust to build secure devices? Whose job is it to find and fix vulnerabilities? How do we balance efficiencies gained by IoT with privacy, dignity and security?
