I think most of us know that smartphones, tablets, and even web browsers track a lot of data about us without us even knowing it. This data has found its way into the hands of some workers in the past to help better target products that consumers. In the future, we will have the Internet of Things where almost everything is web connected. The CIA is really looking forward to this Internet of Things because it offers a better way to track "persons of interest."
CIA director David Petraeus thinks that being able to tap in to connected household devices will change notions of secrecy within our country and make it easier to track suspected terrorists and other enemies of our country. “Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters — all connected to the next-generation internet using abundant, low-cost, and high-power computing,” Petraeus said, “the latter now going to cloud computing, in many areas greater and greater supercomputing, and, ultimately, heading to quantum computing.”
