The document discusses various topics related to biometrics including: 1. Biometrics can be used for physical access control, ATM access, and authenticating transactions over the telephone or from home computers. Fingerprints, iris scans, and facial recognition are some common biometric technologies used. 2. Early biometrics systems from the 1880s involved precise body measurements and physical descriptions but failed by 1903. Modern biometrics use automated methods to recognize individuals based on physiological or behavioral characteristics. 3. Biometrics are part of identity management and can help with security, national security threats, accountability, and optimizing resources. However, biometrics also have limitations like environmental factors affecting performance.
