The document discusses human mobility and social ties based on a 2011 study. It mentions green options like controllers and individuals having power over big data. The section on differential privacy provides a mathematical definition involving randomized functions giving approximately the same results for datasets differing in one element. An image source and joke about binary numbers are also included.

24. DIFFERENTIAL PRIVACY
“A randomized function K gives –differential
privacy if for all data sets D1 and D2 differing
on at most one element, and all S ⊆ Range(K),
where the probability space in each case is
over the coin flips of the mechanism K.”
