EFF’s Street-Level Surveillance Project Dissects Police Technology


Step onto any city street and you may find yourself subject to numerous forms of police surveillance—many imperceptible to the human eye.

A cruiser equipped with automated license plate readers (also known as ALPRs) may have just logged where you parked your car. A cell-site simulator may be capturing your cell-phone data incidentally while detectives track a suspect nearby. That speck in the sky may be a drone capturing video of your commute. Police might use face recognition technology to identify you in security camera footage.
