The Transparent Society is a call for "reciprocal transparency," If police cameras watch us, shouldn't we be able to tune into police stations? If credit bureaus sell our data, shouldn't we know who buys it? Rather than cling to an illasion of anonymity - a historical anomaly, given our origins in close-knit villages - we should focus on guarding the most important forms of privacy and preserving mutual accountability.

The biggest threat to our freedom, Brin warns, is that surveillance technology will be used by too few people, not by too many.
