All eyes from New York’s 15,000 . security cameras


New video From the human rights organization Amnesty International, maps the location of more than 15,000 cameras used by the New York Police Department, both for routine surveillance and in face recognition searches. 3D model shows the camera’s 200-meter range, part of a sweeping traction network that captures the unintended movements of nearly half of the city’s population, placing them in danger for Identification error. The group says it is the first to map the locations of several cameras in the city.

Amnesty International and a team of volunteer researchers have mapped the cameras that can feed the NYPD Lots of criticism for facial recognition Systems in three of the city’s five boroughs – Manhattan, Brooklyn and the Bronx – 15,280 were found in total. Brooklyn is the most watched, with more than 8000 cameras.

A video made by Amnesty International shows how surveillance cameras work in New York City.

“You will never be anonymous,” says Matt Mahmoudi, the artificial intelligence researcher who is leading the project. NYPD used cameras in Approximately 22,000 facial recognition The searches have been since 2017, according to NYPD documents obtained by the Surveillance Technology Watch Project, a New York-based privacy group.

“Whether you’re attending a protest, walking into a particular neighborhood, or even just grocery shopping, your face can be tracked through facial recognition technology using images from thousands of camera points across New York,” Mahmoudi says.

Cameras are often placed on top of buildings, on street lights, and at intersections. The city itself has thousands of cameras. In addition to private companies and homeowners You often grant access to the police.

Police can compare faces captured by these cameras to criminal databases to search for potential suspects. Earlier this year, the NYPD It was required to detect Details of facial recognition systems for public comment. But those disclosures did not include the number or location of the cameras, or any details of how long the data was kept or with whom the data was being shared.

The AI ​​team found that cameras are often clustered in predominantly non-white neighborhoods. The most watched neighborhood in New York City is East New York, Brooklyn, where the group found 577 cameras in less than 2 square miles. More than 90 percent of the population of eastern New York not white According to city data.

facial recognition systems Performance is often less accurate More on dark-skinned people than light-skinned people. In 2016, Georgetown University researchers found that police departments across the country They used facial recognition to identify non-white suspects more than their white counterparts.

In a statement, an NYPD spokesperson said the department never arrests anyone “on the basis of a facial recognition match,” and uses the tool only to investigate a “suspect or suspects in connection with the investigation of a particular crime.”

“When photographs are taken in or near a specific crime, a comparison can be made between the image of the suspect against a database that includes only abstract footage legally preserved in law enforcement records based on previous arrests,” the statement read.

Amnesty International is publishing the map and accompanying videos as part of its #BantheScan campaign urging city officials to ban police use of the tool ahead of the city’s mayoral primaries later this month. In May, deputy Ask the municipal candidates If they support blocking facial recognition. While most did not respond to the inquiry, candidate Diane Morales told the publication she supported the ban, while candidates Sean Donovan and Andrew Yang suggested auditing the divergent impact before deciding on any regulation.
