The Department of Justice is expanding its fingerprint database to include iris scans, photos searchable with face recognition technology, scars, tattoos, and measures of voice and gait. The DoD collects iris scans, prints and face recognition photos from anyone coming in and out of Afghanistan; Department of Homeland Security gathers face recognition photos and fingerprints from people entering the U.S. Even motor vehicle departments in many states use face recognition technology to ID people when they get their licenses, and they tend to be cooperative with criminal investigations. The big agencies are also increasingly making their databases interoperable, so an immigrant's print that lands in the DHS database (IDENT) can be accessed by the FBI. Information is also shared with foreign governments and private companies.
