Over the next year, the DHS will implement changes to facilitate the collection of ten digital fingerprints from international travelers visiting the United States. Under the US-Visit program, the DHS currently collects two digital fingerprints and a digital photograph which are stored to provide the DHS, law enforcement and intelligence agencies with information on biometrics data for visitors to the United States. This data is analyzed and assists in keeping suspected terrorists, immigration violators and criminals outside the United States and ensures public safety. The move to replace the current two-fingerprint scanners with ten-fingerprint scanners was prompted by improvements in security. The DHS already began collecting the ten-fingerprint scans at Washington Dulles International Airport. By early 2008, nine additional airports are expected to transition to the new feature and by the end of 2008, the DHS expects deployment worldwide.
