Documenting Police Tech in Our Communities

Data Library

One of the primary goals of the Atlas of Surveillance is to provide journalists and researchers with the data they need to do in-depth reports on law enforcement surveillance around the country. To that end, we've made our source data available, but we've also compiled this library of data sets and data projects from other organizations that informed the Atlas of Surveillance or are useful in tandem with our research.

Clearview AI Table

Last Updated: April 6, 2021

"Clearview AI has created a powerful facial recognition tool and marketed it to police departments and government agencies. The company has never disclosed the entities that have used its facial recognition software, but a confidential source provided BuzzFeed News with data that appeared to be a list of agencies and companies whose employees have tried or used its technology.

"Using that data, along with public records and interviews [Buzzfeed has] created a searchable database of US-based taxpayer-funded entities, including tribal, local, and state police departments publicly funded university law enforcement bodies; district attorneys’ offices; and federal agencies such as the Air Force and Immigration and Customs Enforcement. [Buzzfeed] included only those agencies for which the data shows that at least one associated individual ran at least one facial recognition scan as of February 2020."

In April 2021, EFF released Data Driven 2: California Dragnet, a public records collection and data set that shines light on the massive amount of vehicle surveillance conducted by police in California using automated license plate readers (ALPRs)—and how very little of this surveillance is actually relevant to an active public safety interest. The data set covered 89 law enforcement agencies in California and is a sequel to EFF's 2018 Data Driven report.
