The US Department of Defense is slowly adopting a biometrics-based system as a possible replacement for its classic card-based access and authentication solution. The new system, called BioTracker, works by logging per-user keyboard typing speed, keystroke style, and mouse use. It then creates a unique fingerprint for each user and uses it to continuously authenticate the DOD employee while using a computer. The system is advertised as a “proof-of-presence”” authentication solution and is currently under testing.”
