The Human Dynamics Lab at the MIT Media Laboratories pioneered the idea of a society enabled by Big Data. The Lab has developed technologies such as reality mining, which uses mobile phone data to extract patterns that predict future human behavior, a `nervous system’ framework for dramatically more efficient transportation, health, energy, and financial systems, the New Deal on Data policies which are now enshrined in the US Consumer Privacy Bill of Rights, and a Trust Network communication architecture that ensures that this new data driven society is secure and fair.
