Government Surveillance

CDT works to subject government surveillance to democratic controls and strengthen oversight of intelligence and law enforcement technology, ensuring personal safety while respecting individuals’ rights.

New technologies are giving governments around the world unprecedented means to collect and access personal information. This includes law enforcement and intelligence agencies demanding content from tech companies and purchasing personal data such as location information from data brokers, the use of surveillance technologies such as license plate readers and facial recognition cameras, and the use of AI to analyze huge swathes of information about individuals and groups.

Much of this government surveillance is aimed at fighting crime and protecting national security, yet in order to ensure basic freedoms, there must be checks and balances on governments’ ability to access, collect, and store people’s data. Both security and freedom can be protected, but only through balanced laws and policies that uphold human rights.
