In January 2020, Hill wrote an article for the
New York Times about
facial recognition company
Clearview AI, describing the company's technology as flawed, which led to privacy-eroding and false arrests by law enforcement agencies due to its erroneous results. In a November 2023 letter to Clearview CEO
Hoan Ton-That regarding concerns about the company's collection of the public's biometric information, senator
Ed Markey (D–MA) cited Hill's article in
The New York Times. In September 2023, Hill authored the book ''Your Face Belongs to Us: A Secretive Startup's Quest to End Privacy as We Know It'', published by
Random House (). The book discusses Clearview AI's facial recognition technology, use by law enforcement and industry, and how it may threaten individuals' safety and privacy. The book was among the list of "Best books of 2023 – Technology" selected by John Thornhill, an editor with the
Financial Times. It was shortlisted for the 2024
Royal Society Trivedi Science Book Prize. On March 11, 2024, the
New York Times published a story authored by Hill in which she wrote about how automakers such as
General Motors,
Honda,
Kia, and
Hyundai were sharing driver data with data brokers like
LexisNexis in violation of privacy policy. On March 22, 2024, GM announced it was ending the practice. According to her follow-up article on April 30, 2024, senators
Ron Wyden (D–OR) and
Ed Markey (D–MA) requested the
Federal Trade Commission to investigate data sharing practices. == Personal life ==
